New Navy stealth destroyer under construction in Maine

BATH, Maine — Even though the Navy reduced its goal for overall number of ships, Bath Iron Works should stay busy over the coming years because the number of large warships like those built there would increase by 30 percent under the proposal, Sen. Susan Collins said Wednesday.

The 30-year plan unveiled last week would increase the number of "large surface combatants" — destroyers and cruisers — by a total of 16 ships, even as the total fleet size would be reduced from 313 to 300, Collins said. The Navy currently has about 285 ships.

"It's a good start — a very good start," said Collins, who joined Adm. Jonathan Greenert on his first visit to Bath Iron Works since becoming chief of naval operations.

Greenert viewed assembled hull segments of the future USS Zumwalt after participating in a ceremony marking the start of construction of the third and final warship in the line.

Once maligned for its high cost, the stealthy Zumwalt is now viewed as well suited to the Navy's new focus on the Asia and the Pacific, where the U.S. intends to bolster its military presence in response to Asia's growing economic importance and China's rise as a military power.

The 600-foot-long warships are the largest destroyers to be built in Bath but will have an element of stealth because of their low-to-the-water profile. They feature 155 mm deck guns with rocket-propelled warheads that can hit targets 100 miles away.

They have electric-drive propulsion, an unconventional wave-piercing hull, new sonar system and the ability to launch multiple aerial drones, in addition to new strike capabilities. They'll also require half the number of sailors to operate as existing Arleigh Burke-class destroyers.

"The DDG-1000 fits in perfectly with our strategy. It's perfect for the Asia-Pacific," said Greenert, who declared the futuristic warship to be "a marvel of engineering."

While it's technologically sophisticated, it's also a symbol of defense programs that exceeded budget projections. The Navy had to truncate the program to just three ships because of spiraling costs, now estimated to be more than $3 billion per ship, compared to about $1.2 billion for the current class of ships.

After the three destroyers are built, the Navy will shift back to construction of Arleigh Burke-class destroyers, which are cheaper and have ballistic defense capabilities.

Collins, who serves on the Armed Services Committee and invited Greenert to tour the shipyard, said she's seeking to have a 10th ship added to a nine-ship purchase for fiscal years 2013 through 2017. That could be more good news for Bath Iron Works, a General Dynamics subsidiary, and its 5,400 shipbuilders.

In general, the new focus on Asia could mean more dollars for the Navy, which has seen funding reductions during the wars in Afghanistan and Iraq, said Loren Thompson, a defense analyst at the Lexington Institute.

"The Obama administration's shift to an Asia-Pacific strategy is very good news for the Navy. That probably means good news for Bath Iron Works, too," he said.

While meeting with reporters, Greenert was asked about prospects that another Navy shipyard, the Portsmouth Naval Shipyard on the Maine-New Hampshire border, could be on the chopping block if there's another round of base closings.

"Portsmouth fills a critical need for overhaul of our submarines and provides other things as well. I don't see that need diminishing at all in the future," he said.

Vraag me af hoe lang ze nog door willen met de Arleigh Burke. Het schip is inmiddels 20 jaar in productie, en met een crew van bijna 400 best zwaar bemand. Nu dus weer terug naar dat 'oude model', maar vraag me toch af wanneer er een echte opvolger komt. Het hoeft ook niet zo moeilijk te zijn, gewoon een modern schip, gebaseerd op moderne technologie, niet perse helemaal van de grond af opgebouwd. Het LCF kostte maar 10% van wat de Zumwalt kost, een veel kleiner schip ook, maar het zet je wel aan het denken...

Men kan inderdaad wat 'te ver gaan' met ontwikkeling en technologie: het moet nog steeds betaalbaar blijven.
Persoonlijk vind ik de Burkes best wel goed en ik ben er zeker van dat die ook met minder bemanningsleden ook nog effectief uitgebaat kunnen worden.

Uit persoonlijke ervaring weet ik dat men bij de Amerikanen veel meer crew heeft voor het uitbaten van bv wapensystemen ivm het personeel dat wij op fregatten hebben.
Een 5" gun crew op een Tico bestond al uit bijna 20 (!) man.
Met twee zulke torens per schip kwam je dus al op 35-40 man (de CPOs waren verantwoordelijk voor de twee torens).
Ze zijn ook veel te "gespecialiseerd": Gun mechanic, Gun Electrician, Gun Hydraulic Technician enz.
Wij doen al die functies samen.
Misschien niet zo "hoog opgeleid" of "gespecialiseerd" echter nog steeds effectief en veel goedkoper...
Zij hebben dan weer het voordeel minder "rollen" te hebben per bemanningslid/functie.

Een type schip als de Zumwalt is toch om een bombardement op de kust/ver- landinwaards te doen ? , zo'n type destroyer vaart er nu nog niet eens rond ..een schip van dat kaliber. Ik zie wel wat in zo'n type schip met een overmacht aan fire-power met veel verschillende wapensystemen. Voor onze Marine, zou je kunnen denken aan fregatten/destroyers type LCF met 155mm geschut en tomahawks. Van zo'n schip gaat natuurlijk al een grote dreiging uit, veel meer dan van een normaal fregat met een veel lichtere bewapening en vaak ook niet geschikt om echt wat uit te halen op het land.

Zo'n schip bestaat wel. In principe kun je met een Ticonderoga Kruiser een flink bombardement diep land inwaards uitvoeren, dat ding neemt maximaal 120 Tomahawks mee. De Zumwalt is een destroyer en kent wat andere oplossingen voor de gestelde uitdagingen.

Cutting edge warship a 'silver bullet'

5:45 AM Saturday Apr 14, 2012

An enormous, expensive and technology-laden warship that some navy leaders once tried to kill because of its cost is now viewed as an important part of the Obama Administration's Asia-Pacific strategy, with advanced capabilities that the navy's top officer says represent the navy's future.

The stealthy, guided missile-armed Zumwalt taking shape at Bath Iron Works is the biggest destroyer ever built for the United States Navy.

The low-to-the-water warship will feature a wave-piercing hull, composite deckhouse, electric drive propulsion, advanced sonar, missiles and powerful guns that fire rocket-propelled warheads as far as 160km.

It's longer and heavier than existing destroyers but will have half the crew because of automated systems.

"With its stealth, incredibly capable sonar system, strike capability and lower manning requirements, this is our future," concluded Admiral Jonathan Greenert, chief of naval operations, who gave the warship his endorsement on a visit last week to Bath Iron Works, where the ships are being built.

It wasn't always this way.

The General Accounting Office expressed concerns that the Navy was trying to incorporate too much new technology.

Some Navy officials pointed out that it's less capable than existing destroyers when it comes to missile defence, and a defence analyst warned that it would be vulnerable while operating close to shore for fire support.

Even its "tumblehome" hull was criticised as potentially unstable in certain situations.

The 182m-long ships are so big that the General Dynamics-owned shipyard spent US$40 million to construct a 32m-tall building to assemble the giant hull segments.

And then there's the cost, roughly US$3.8 billion ($4.6 billion) apiece, the Navy's proposed budget says.

Including research and development, the cost grows to US$7 billion apiece, said Winslow Wheeler, director of the Straus Military Reform Project at the Centre for Defence Information in Washington.

Because of the cost, the originally envisioned 32 ships dipped to 24 and then seven. Eventually, the programme was truncated to just three. The first, the Zumwalt, will be christened next year and delivered in 2014.

But Greenert said the ship fits perfectly into the new emphasis on bolstering the US military presence in the Pacific in response to Asia's growing economic importance and China's rise as a military power.

Greenert didn't go into detail on how the new ship could be used. But the Defence Department has expressed concerns that China is modernising its Navy with a near-term goal of stopping or delaying US intervention in a conflict involving Taiwan.

China considers the self-governing island a renegade province. Defence officials also see a potential flashpoint in the South China Sea, where China's territorial claims overlap with those of Vietnam, the Philippines and Malaysia.

The Zumwalt's new technology will allow the warship to deter and defeat aggression and to maintain operations in areas where an enemy seeks to deny access, both on the open ocean and in operations closer to shore, the Navy says.

Jay Korman, industry analyst with The Avascent Group, said the warship uses so much new technology that it's viewed by the Navy as a "silver bullet" answer to threats. The only problem is the cost.

"They were looking to introduce so many new technologies at once, and the cost ballooned," he said. "I don't think people have changed their minds that it's a capable ship. It's just too expensive."

The Zumwalt's 155mm deck guns were built to pound the shore with guided projectiles to pave the way for the Marines to arrive in landing craft, and they're far more cost-effective in certain situations than cruise missiles, said Eric Wertheim, author of the Naval Institute's Guide to Combat Fleets of the World.

The smaller crew also represents a substantial cost saving, he added.

The ship could one day be equipped with an electromagnetic railgun, a powerful weapon that fires a projectile at several times the speed of sound.

Navy Names Zumwalt Class Destroyer USS Lyndon B. Johnson


            Secretary of the Navy Ray Mabus announced today the next Zumwalt-class destroyer will be named the USS Lyndon B. Johnson.

            The selection of Lyndon B. Johnson, designated DDG 1002, continues the Navy tradition of naming ships after presidents and honors the nation's 36th president.

            The USS Lyndon B. Johnson is the 34th ship named by the Navy after a U.S. president.

            "I am pleased to honor President Johnson with the naming of this ship," Mabus said.  "His dedication to a life of public service included bravely stepping forward to fight for his country during our entry into World War II."

            A Texas congressman, Johnson was the first member of Congress to enlist in the military following the start of World War II.  After his naval service, Johnson was elected to the U.S. Senate in 1948, where he served as both minority and majority leader before being elected vice president Nov. 8, 1960.

            Following President Kennedy's assassination Nov. 22 1963, Johnson succeeded to the presidency, finished the remaining term, and was reelected for a full term as president, by the greatest percentage of total popular vote (61 percent) ever attained by a presidential candidate.

            Johnson's time as president was marked by the passage of programs that greatly influenced and impacted education, healthcare and civil rights for generations to come.   He signed the Civil Rights Act of 1964 into law, enacting comprehensive provisions protecting the right to vote and guarding against racial discrimination.  His work on civil rights continued with the passage of the Voting Rights Act, which guaranteed voting rights for all people, regardless of race. 

            Johnson signed legislation establishing Medicare, which allowed millions of elderly Americans access to cheaper medical services.  He also launched the Head Start Program, which provided preschool children from low-income families with classes, medical care, and other services.

            As a naval officer, Johnson requested a combat assignment after the attack on Pearl Harbor and served in the Pacific theater during World War II.  After returning from active duty service, Johnson reported back to Navy leaders and Congress on what he believed were deplorable conditions for the warfighters, and continued to fight for better standards for all military members.

            USS Lyndon B. Johnson will be the third Zumwalt-class (DDG 1000) destroyer. Construction began on the ship at General Dynamics-Bath Iron Works April 4 and is expected to deliver to the Navy in fiscal 2018.  The multimission DDG 1000 class destroyers are designed for sustained operations in the littorals and land attack and will provide independent forward presence and deterrence, support special operations forces, and operate as an integral part of joint and combined expeditionary forces.  This warship integrates numerous critical technologies, systems, and principles into a complete warfighting system.  Zumwalt ships will be 600 feet in length, have a beam of 80.7 feet, displace approximately 15,000 tons, and capable of making 30 knots speed.  Each ship will have a crew size of 148 officers and Sailors.

            Media may direct queries to the Navy Office of Information at 703-697-5342.  For more news from secretary of the Navy public affairs, visit www.navy.mil/SECNAV .

Stealth destroyer, at over $3 billion apiece, is US Navy's latest answer to rising China

By Associated Press, Updated: Monday, June 4, 11:10 AM

SINGAPORE — A super-stealthy warship that could underpin the U.S. navy's China strategy will be able to sneak up on coastlines virtually undetected and pound targets with electromagnetic "railguns" right out of a sci-fi movie.

But at more than $3 billion a pop, critics say the new DDG-1000 destroyer sucks away funds that could be better used to bolster a thinly stretched conventional fleet. One outspoken admiral in China has scoffed that all it would take to sink the high-tech American ship is an armada of explosive-laden fishing boats.

With the first of the new ships set to be delivered in 2014, the stealth destroyer is being heavily promoted by the Pentagon as the most advanced destroyer in history — a silver bullet of stealth. It has been called a perfect fit for what Washington now considers the most strategically important region in the world — Asia and the Pacific.

Though it could come in handy elsewhere, like in the Gulf region, its ability to carry out missions both on the high seas and in shallows closer to shore is especially important in Asia because of the region's many island nations and China's long Pacific coast.

"With its stealth, incredibly capable sonar system, strike capability and lower manning requirements — this is our future," Adm. Jonathan Greenert, chief of naval operations, said in April after visiting the shipyard in Maine where they are being built.

On a visit to a major regional security conference in Singapore that ended Sunday, U.S. Defense Secretary Leon Panetta said the Navy will be deploying 60 percent of its fleet worldwide to the Pacific by 2020, and though he didn't cite the stealth destroyers he said new high-tech ships will be a big part of its shift.

The DDG-1000 and other stealth destroyers of the Zumwalt class feature a wave-piercing hull that leaves almost no wake, electric drive propulsion and advanced sonar and missiles. They are longer and heavier than existing destroyers — but will have half the crew because of automated systems and appear to be little more than a small fishing boat on enemy radar.

Down the road, the ship is to be equipped with an electromagnetic railgun, which uses a magnetic field and electric current to fire a projectile at several times the speed of sound.

But cost overruns and technical delays have left many defense experts wondering if the whole endeavor was too focused on futuristic technologies for its own good.

They point to the problem-ridden F-22 stealth jet fighter, which was hailed as the most advanced fighter ever built but was cut short because of prohibitive costs. Its successor, the F-35 Joint Strike Fighter, has swelled up into the most expensive procurement program in Defense Department history.

"Whether the Navy can afford to buy many DDG-1000s must be balanced against the need for over 300 surface ships to fulfill the various missions that confront it," said Dean Cheng, a China expert with the Heritage Foundation, a conservative research institute in Washington. "Buying hyperexpensive ships hurts that ability, but buying ships that can't do the job, or worse can't survive in the face of the enemy, is even more irresponsible."

Railgun and Stealth Technology Make Navy DDG-1000 Super Ship the Weapon of the Future

The Navy has given more publicity to its new Zumwalt-class destroyer, the DDG-1000, in the hope that, as the world's most advanced floating piece of technology, it will provide a deterrent and an answer to the rising Chinese influence in the Pacific.

The ship boasts sci-fi-like capacities that anybody could be in awe over: "cloaking" technology and a super-powerful "railgun" weapon. 

Designed to engage its adversaries in coastal waters, this ship's primary role is to maintain access to the shores of a competitor. However, the high $3 billion per-unit cost and the technological challenges that are yet unsolved or deemed ineffective in light of more conventional solutions are the main stumbling blocks for the realization of the vessel. At this point being little more than a conceptual technology demonstrator, the redeeming quality of this project is that it offers the best alternative to the need for providing new ships to the Navy after 2030, when the resources of most current vessels will expire.

Its large price tag and limited numbers in an age of austerity make it a dubious investment now — but not in the long term.

The context of this development comes from the birth of China's aircraft carrier fleet with the ex-Soviet Varyag, along with its rapidly swelling military budget on the one hand, and Washington's Asia pivot, along with Secretary of Defense Leon Panetta's recent announcement that 60% of American naval capacities will be concentrated in the Pacific, on the other hand.

For Washington, China is something like a simultaneous friend and enemy. The hope is that Beijing will keep crediting America so that the two can continue to play strategic competition. In light of its fiscal difficulties, it seems ill-advised for the U.S. to enter into direct military competition with China. From the first link, the orders of this new vessel went from 32 to 3, or a reduction by 90%. It is not altogether unexpected, as the hefty price tag of $3 billion a pop makes the vessel a forbidding investment. With an expected strength of 300 U.S. vessels, a 1% production scope will make the evaluation of the Zumwalt destroyers in practical conditions a challenge. Their application and effects are constrained by virtue of their small numbers.

On the positive side, as a test bed for new technologies, the DDG-1000 allows for effective planning on what the Navy will look like in the span of the next 50-70 years. American maritime doctrine is based on the principle of universal accessibility, achieved through 11 aircraft carriers and their battle groups. An aircraft carrier is operable between 40-60 years before needing replacement, and the current generation of Nimitz-class carriers are nearing the halfway point of their useful life. The plans are calling for the introduction of the Gerald Ford-class of carriers, which will begin to roll out mid-decade and be fully implemented by the mid-2030s. In this respect, these ships will be the center of U.S. naval doctrine until the beginning of the 22nd century and will probably include many of the technological developments in the Zumwalt class.

The geopolitical shifts in the Pacific show that the priority has shifted to preserving America's influential naval capacity, rather than its leading strategic role in the world during the course of this century, which will be ceded to China in due time. The introduction of advanced platforms that do more with less, albeit costing more, is indicative of this trend.

While the Zumwalt class will most likely be matched and outperformed by Chinese money and technology in the short to medium term, it is the long-game perspective we must recognize in seeing the value of this ship. It can be said that it is not very applicable to today's maritime strategic environment, but more so to its future.

Newest Navy warship DDG-1000 destroyer cost a staggering $3.1 billion per unit

The Associated Press is reporting a story concerning a new "Zumwalt" class destroyer being built in Maine called "the most advanced warship in modern history."

The new ship the "DDG-1000 destroyer is being nicknamed the "silver bullet", not only because it sort of resembles a silver metallic beer can in the middle but because it can travel at supposedly "super stealth" speed along an enemies coast line, even in the shallows.

The new warship could deploy it as early as 2014 and will be equipped with all the latest in high tech including so called: "electromagnetic rail guns" that with the help of a magnetic field and electric current will run projectiles at speeds several times faster than the speed of sound.

The ships are supposedly equipped with an "electric motor" and the most advanced sonar devices and missiles in the U.S. arsenal.

The one great advantage besides the speed is the fact that it is stealthy and will only give off a reduced radar signature comparable to that of a small fishing vessel a fraction of its real size.

The drawbacks are in terms of the weight – they are much heavier than other ships it terms of its size, meaning it will be harder to propel forward through the water.

Defense News reported this about the new warship, which is rather interesting:
"Nothing like the Zumwalt has ever been built. The 14,500-ton ship's flat, inward-sloping sides and superstructure rise in pyramidal fashion in a form called tumblehome. Its long, angular "wave-piercing" bow lacks the rising, flared profile of most ships, and is intended to slice through waves as much as ride over them...."

"At least eight current and former officers, naval engineers and architects and naval analysts interviewed for this article expressed concerns about the ship's stability. Ken Brower, a civilian naval architect with decades of naval experience was even more blunt: "It will capsize in a following sea at the wrong speed if a wave at an appropriate wavelength hits it at an appropriate angle".... (see 2007 article: Defense News: Will DDG-1000 Destroyers Be Unstable? Defense News: Will DDG-1000 Destroyers Be Unstable? http://www.defenseindustrydaily.com/defense-news-will-ddg1000-destroyers... ).

The Navy apparently wanted 32 of the expensive new toys, which cost $3.1 billion a piece to build, but had to settle for 3 because of a lack of Congressional support.

Critics believe that this Pentagon's project is a "money pit" of waste that is sucking cash from the Treasury...

It is also highly dependent on modern electronics...

One critic claims it is not hardened to EMP or "electromagnetic pulse" and could be disabled by the new generation of small "EMP bombs" being developed which are the size of a large suitcase. "Get one on board or inside the ship and set it off it will be a sitting duck in the water", the source said. I should note that we however have no real way of verifying that sort of information.

Pravda.ru is reporting that Chinese Admirals appeared on local TV recently appeared to be openly mocking the new weapon. One is reported to have said that all the talk about the invincibility of the new destroyers is no more than "advertising hype" on the part of the U.S. military, adding that any "high tech" ship of the United States can be easily sunk by a simple fishing boat loaded with explosives.

An apparent reference to the U.S.S. Cole attack in October 2000.

The USS Cole bombing was a suicide attack against the United States Navy destroyer USS Cole, while it was harbored and being refueled in the Yemeni port of Aden. In that sneak attack seventeen American sailors were killed, and 39 were injured. The attack effectively rendered the Cole dead in the water. It was an asymmetric warfare attack was organized and directed by the terrorist organization al-Qaeda using about 400- pounds of explosives put on a small craft that approached the port side of the destroyer.

The explosion caused a 40-by-40-foot gash in the ship's port side, according to reports at the time.

This event was the deadliest attack against a United States Naval vessel since 1987.
The terrorist organization al-Qaeda claimed responsibility for the attack, which stunned military officials because it was so low tech.

The new warship has already been compromised is so far as it has been photographed already while in dry dock by various people including one citizen David Long who posted these very interesting online comments on Friday June 8, 2012 on facebook:

"I am just wondering why there are two of these sitting in the Naval yard in dry dock at the Norfolk, VA shipyard? I am wondering why the most advanced starwars looking ships already exist....just go look for yourself, you can see them from the sand spit or over by Rebel Marina. They are huge, have no windows and clearly sport technology that could probably take them to space. I know, I was there anchored out in my sailboat in January (being buzzed 24/7 by the way by helicopters and surveillance planes) because I was accidentally anchored right on the "no pass" line about five miles from the base. I will add that there isn't exactly a red stripe sitting on top of the ocean, so I gave it a pretty good safety factor before I dropped anchor. I learned during the year I was down there that they have an incredible amount of really advanced things in their toy box, and you don't want to mess with those guys. Lie everything the military does...they tell us they are going to build a Stealth bomber after they had ten years of them lying around. No need to wonder about the 2.3 mission trillion went. I have some photos by accident as I took some pictures of my sailboat at anchor and the futuristic ships are in the background. I would probably go to an undisclosed CIA prison if I posted them, so I won't unless I get permission from the Secretary of the Navy or something. I guess you will have to go look. Might even be on Google Earth. There are many other highly advanced ships and helicopters over there as well in plain sight, Makes you wonder. Dl."

Construction Of USS Zumwalt Reaches Milestone
Author:Daniel Goure, Ph.D.
Date:Thursday, December 20, 2012
TagsDDG 1000

A few days ago, construction of the first DDG 1000, the USS Zumwalt, passed a milestone. Seemingly without effort, the skilled workers at Bath Iron Works shipyard raised a 1,000 ton deckhouse 95 feet in the air, slid the ship's hull underneath and lowered this massive structure to its precise position on the Zumwalt's deck. If you want to see what this looks like go to Chris Cavas' piece on the Defense News blog.

The DDG 1000 is a marvel of naval design and U.S. technological ingenuity. 155 feet long and 65 feet high, the integrated deckhouse, built entirely of composites and designed to reduce the ships' radar, infrared and electromagnetic signatures, is just one of the Zumwalt's advanced features. The deckhouse also contains the ship's high tech bridge, and the dual-band radar capable of seeing and tracking dozens of targets from long-range ballistic missiles to fast, sea-skimming cruise missiles. Other state-of-the-art features of the Zumwalt include: an integrated sonar system with advanced towed array and high-frequency active sonar, an electric drive that not only turns the ship's propellers but produces ten times the electric power as is available on current destroyer classes, a total ship computing environment infrastructure that improves overall ship performance and reduces the crew requirement, the advanced gun system with large magazines and the Mk 57 Peripheral Vertical Launching System (PVLS) that distributes a total of 80 missile cells in 20 reinforced launchers along the edges of the ship for safety and has the space to hold future, larger missiles.

If the Navy were to design a surface combatant for the recently announced pivot to the Asia-Pacific region, it would be the DDG 1000. This is the quintessential "full spectrum of missions" region. Zumwalt's reduced signatures, powerful sensors and multi-role weapons systems are exactly what a force planner will want for a region that is witnessing an explosive proliferation of modern weapons, including advanced ballistic and cruise missiles, conventional and nuclear attack submarines, fourth and fifth generation aircraft and new generation sensors. The advanced gun system and PVLS will provide a range of options for responsive, precision attack. The large hangar and aviation deck will permit deployment of both helicopters and unmanned rotary wing vehicles such as the Fire Scout to support both combat and humanitarian assistance missions.

The current plan is to build only three DDG 1000s and complement their capability with production of advanced variants of the venerable Arleigh Burke DDG 51. Given the challenges of the new strategy and despite projected defense budgets reductions, the Obama Administration would be well-advised to consider increasing production of both ship classes.

US Navy's lead Zumwalt-class destroyer commences sea trials

Grace Jean, Washington, DC - IHS Jane's Navy International | 08 December 2015

The lead ship of the US Navy's (USN's) new destroyer class has begun initial sea trials in the Atlantic Ocean, navy officials confirmed on 8 December.

Built by General Dynamics Bath Iron Works, Zumwalt (DDG 1000) departed the Bath, Maine, shipyard for the first time on 7 December. The vessel headed out to sea with representatives from Bath Iron Works, the USN's DDG 1000 programme office, the ship's company, and technical experts embarked.

" Zumwalt 's first underway period is a significant milestone as it marks the culmination of years of hard work and dedication on behalf of our navy and industry team," Captain Jim Downey, the DDG 1000 programme manager, said in a statement.

As part of the sea trials, the navy will demonstrate a number of Zumwalt 's key systems and technologies as it seeks to use the initial trials period to help identify issues and mitigate risks for the programme, said Naval Sea Systems Command (NAVSEA) spokesperson Matt Leonard.

Designed for land-attack missions, the 185.9 m-long Zumwalt features a tumblehome hull design and a new Advanced Gun System (AGS), and also introduces a number of automated shipboard functions.

"We look forward to continuing our rigorous testing plan at sea as we ensure safety, capability, and quality in preparation for sail away," Capt Downey said.

Zumwalt is expected to achieve initial operational capability in 2016.

Key Points
• Zumwalt (DDG 1000) is expected to return to sea in February for builder's trials
• Delivery of the lead ship is planned for April 2016

After completing its first at-sea underway period, the lead ship of the US Navy's (USN's) Zumwalt-class (DDG 1000) destroyer is preparing for builder's trials in February.

Assuming the second set of sea trials go well, Zumwalt (DDG 1000), which completed alpha sea trials in early December 2015, will proceed to acceptance trials in the March timeframe with a planned delivery in April, DDG 1000 programme manager Rear Admiral (select) James Downey said at the Surface Navy Association's annual symposium on 14 January.

During its seven-day alpha trials, Zumwalt performed well and demonstrated better than expected stability, officials said. The 186 m (610 ft) ship ran up to full power (up to 33 kt) and was able to stop completely in 90 seconds. As part of the trials, it also accomplished full rudder swings, demonstrating less than 8 degrees of list.

"The faster it goes, the faster it responds," Rear Adm Downey said, adding that the propulsion plant was exercised in more than a dozen configurations and exceeded requirements. Zumwalt encountered 8 to 10 ft seas in the Gulf of Maine, but otherwise did not see significant bad weather. Its razor-sharp bow was able to pierce though the water, officials noted. The team also gathered good data on the hull's radar cross-section, which is performing well.

Second-in-class Michael Monsoor (DDG 1001) is 84% complete at General Dynamics Bath Iron Works in Bath, Maine, and is expected to be ready for launch by the end of June. Meanwhile, the third and final Zumwalt destroyer Lyndon B Johnson (DDG 1002) is 43% complete, with 90 of 97 of its units under construction. Production of its deckhouse - which reverted back to an all-steel design from the original composite found on the first two ships - is also underway, Rear Adm Downey said.

USN's Zumwalt completes builder's trials

Grace Jean, Washington, DC - IHS Jane's Defence Weekly | 29 March 2016

The lead ship of the US Navy's (USN's) new destroyer class is back in port after completing builder's trials, officials announced on 25 March.

Future USS Zumwalt (DDG 1000) conducted four days of at-sea trials as part of the USN's testing and evaluation process. Produced by General Dynamics Bath Iron Works in Bath, Maine, Zumwalt underwent testing of several ship systems including key propulsion and auxiliary systems as well as small boat operations.

"These trials also served as a unique opportunity for the crew to train side-by-side with representatives from industry," Captain Thurraya S Kent, a spokesperson for the Assistant Secretary of the Navy for Research, Development and Acquisition Sean Stackley, said in a statement. "The navy will continue to assess system performance over the coming weeks in preparation for acceptance trials next month."

Designed for land-attack missions, the 185.9 m-long ship features a tumblehome hull design and is fitted with a new Advanced Gun System (AGS).

Zumwalt is expected to achieve initial operational capability this year.

At Sea Aboard the Zumwalt

Christopher P. Cavas, Defense News | March 31, 2016

ABOARD THE DESTROYER ZUMWALT — "All ahead one third on the starboard shaft." The order was called out by the Bath Iron Works (BIW) conning officer, clearly heard in the hushed atmosphere of the pilot house. The bridge was dark except for the dim glow of flat-panel displays as the 16,000-ton destroyer moved away from the Portland, Maine, pier.

US Navy Accepts Delivery of Future USS Zumwalt (DDG 1000)

US Navy | May 20, 2016

BATH, Maine (NNS) -- The Navy accepted delivery of future USS Zumwalt (DDG 1000), the lead ship of the Navy's next-generation of multimission surface combatants, May 20.

DDG 1000 is tailored for sustained operations in the littorals and land attack, and will provide independent forward presence and deterrence, support special operations forces, and operate as an integral part of joint and combined expeditionary forces.

Ship delivery follows extensive tests, trials and demonstrations of the ship's hull, mechanical, and electrical systems including the ship's boat handling, anchor and mooring systems as well as major demonstrations of the damage control, ballasting, navigation and communications systems.

"Today represents a significant achievement for not only the DDG 1000 program and shipbuilding team but for the entire U.S. Navy," said Rear Adm. (select) Jim Downey, DDG 1000 program manager, Program Executive Office Ships. "This impressive ship incorporates a new design alongside the integration of sophisticated new technologies that will lead the Navy into the next generation of capabilities."

The 610-foot, wave-piercing tumblehome ship design provides a wide array of advancements. The shape of the superstructure and the arrangement of its antennas significantly reduce radar cross section, making the ship less visible to enemy radar at sea.

Zumwalt is the first U.S. Navy surface combatant to employ an innovative and highly survivable Integrated Power System (IPS) distributing 1000 volts of direct current across the ship. The IPS' unique architectural capabilities include the ability to allocate all 78 megawatts of installed power to propulsion, ship's service, and combat system loads from the same gas turbine prime movers based on operational requirements. Each ship in the class features a battery of two Advanced Gun Systems, capable of firing Long-Range Land Attack Projectiles (LRLAP) that reach up to 63 nautical miles, providing three-fold range improvement in naval surface fires coverage. Each ship is equipped with eighty Advanced Vertical Launch System cells for Tomahawk missiles, Evolved Sea Sparrow Missiles, Standard Missiles, and Vertical Launch Anti-Submarine Rockets (ASROC) (VLA).

The ship will employ active and passive sensors and a Multi-Function Radar (MFR) capable of conducting area air surveillance, including over-land, throughout the extremely difficult and cluttered sea-land interface.

Following delivery and a crew certification period at General Dynamics-Bath Iron Works, the ship will be commissioned in Baltimore Oct. 15. Zumwalt will then transit to her homeport in San Diego where Mission Systems Activation will continue in parallel with a Post Delivery Availability.

"Zumwalt's crew has diligently trained for months in preparation of this day and they are ready and excited to take charge of this ship on behalf of the U.S. Navy," said Capt. James Kirk, commanding officer of future Zumwalt. "These are 143 of our nation's finest men and women who continue to honor Adm. Zumwalt's namesake with their dedication to bringing this ship to life."

BIW is also constructing follow-on ships, the future Michael Monsoor (DDG 1001) and Lyndon B. Johnson (DDG 1002).

As one of the Defense Department's largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and special warfare craft.

Future USS Zumwalt will have San Diego Homeport

US Navy | May 20, 2016

SAN DIEGO (NNS) -- The Navy announced today the future next-generation guided-missile destroyer USS Zumwalt (DDG 1000) is scheduled to be homeported at Naval Base San Diego following its commissioning in fall 2016. Zumwalt is scheduled to arrive in San Diego in late 2016.

Construction of Zumwalt commenced February 2009 and the ship was launched Oct. 29, 2013. Currently, the ship is conducting hull, mechanical, and electrical tests and trials with a subsequent period to follow for combat and mission system equipment installation, activation, and testing.

The ship is commanded by Capt. James A. Kirk.

DDG 1000 is the lead ship of a class of next-generation multimission surface combatants tailored for land attack and littoral dominance with capabilities to defeat current and projected threats. Zumwalt will triple naval surface fire coverage, add an improved sonar system to track deep and shallow water threats, as well as pace current anti-ship cruise missile threats. For today's warfighter, DDG 1000 fills an immediate and critical naval warfare gap, meeting validated Marine Corps fire support requirements.

The multimission DDG 1000 is tailored for sustained operations in the littorals and land attack, and will provide independent forward presence and deterrence, support special operations forces, and operate as an integral part of joint and combined expeditionary forces. Its multimission design and littoral capabilities make it a 100 percent globally deployable asset to the fleet.

The U.S. Navy continually monitors force readiness and ability to provide the most robust, capable maritime force possible. Stationing destroyers in a West Coast port supports rebalance to the Indo-Asia-Pacific region, placing our most advanced capabilities and greater capacity in that vital theater. By 2020, approximately 60 percent of Navy ships and aircraft will be based in the region.

Future USS Zumwalt to Depart Norfolk for Baltimore

(Source: U.S Navy; issued Oct 6, 2016)

NORFOLK, Va --- The future USS Zumwalt (DDG 1000) is scheduled to depart Naval Station Norfolk Oct. 7 and complete a one-day transit to Baltimore, Md., where it will be commissioned into active service on Oct. 15, during Fleet Week Maryland.

Zumwalt was originally scheduled to depart Norfolk on Oct. 9 but, with the approach of Hurricane Matthew, the Navy made the prudent decision to move up the ship's departure and complete preparations for the commissioning ceremony in Baltimore.

The Navy's newest and most technologically advanced surface ship, Zumwalt is the lead ship of a class of next-generation multi-mission destroyers designed to strengthen naval power. The ships are capable of performing critical maritime missions and they enhance the Navy's ability to provide deterrence, power projection and sea control.

Stealthy, powerful and lethal, Zumwalt's integration into the fleet will provide a vital link from the Navy's current needs to its future capabilities.

Named for Adm. Elmo R. "Bud" Zumwalt Jr., former chief of naval operations (CNO) from 1970 to 1974, the Zumwalt-class features a state-of-the-art electric propulsion system, a wave-piercing tumblehome hull, stealth design and the latest war fighting technology and weaponry available.

A veteran of World War II and the conflicts in Korea and Vietnam, Adm. Zumwalt exemplified honor, courage and commitment during 32 years of dedicated naval service, earning a Bronze Star with Valor for his actions during the Battle of Leyte Gulf.

During his time as CNO, Adm. Zumwalt embraced technological innovation and advocated a number of successful programs including, the Oliver Hazard Perry-class frigate, the Ohio-class ballistic missile submarine and the F-14 Tomcat, all of which yielded long-term benefits to the warfighting readiness of the Navy. His legacy is proudly carried on today by the new class of destroyers that bear his name.

USN considers options for replacing Zumwalt's LRLAP projectile

Geoff Fein, Washington, DC - IHS Jane's Defence Weekly - 29 December 2016

(https://www.defensieforum.nl/Forum/proxy.php?request=http%3A%2F%2Fwww.janes.com%2Fimages%2Fassets%2F566%2F66566%2F1651238_-_main.jpg&hash=9f9a874dc762a324dadaf65cb87155ec2f375a07)

Key Points
. Three possible solutions exist for a LRLAP replacement: Excalibur, MS-SGP, and the Hyper Velocity Projectile
. Replacing LRLAP, which was developed specifically for AGS, could add further costs to Zumwalt's price tag

The Long Range Land Attack Projectile (LRLAP), originally designed for USS Zumwalt 's (DDG 1000) Advanced Gun System (AGS), has become too expensive and the US Navy (USN) is exploring options to replace the round, sources told IHS Jane's .

However, AGS was built specifically by BAE Systems to handle only LRLAP rounds, which means there are few, if any, projectiles that could seamlessly transition to fill the 155 mm requirement. The navy is considering two potential options: Raytheon's 155 mm Excalibur 1b and BAE Systems' Multi-Service Standard Guided Projectile (MS-SGP). A third option could be to speed development of the Hyper Velocity Projectile (HVP) that was originally designed for the electromagnetic railgun.

BAE Systems and Raytheon declined to comment for this story.

Industry sources said the navy is leaning towards Excalibur because it is the only one of those three projectiles currently in production. It is unlikely to be a one-for-one replacement whichever route the navy takes to replace the LRLAP (currently priced between USD800,000 and USD1 million per projectile, while Excalibur costs about USD68,000 per round).

The navy has said no decision has been made for replacing the LRLAP. The USN has approximately 90 LRLAP test rounds in its inventory to conduct Zumwalt 's combat system and AGS tests. However, if the navy has no plan to buy further LRLAP rounds from Lockheed Martin, the service may be less inclined to incur the cost of conducting any weapon system testing until officials decide which projectile will be fired from the AGS.

Even if the USN opts to transition Excalibur from land forces to a navy gun, there is much to consider: could Excalibur be fired from the AGS; would the AGS's unique magazine and loading system need to be modified to handle another projectile; and would the navy be giving up any capability by procuring Excalibur or another projectile for Zumwalt ?

Tussen de 800.000 en 1.000.000 USD per FUCKING schot?????!!! Wie is er omgekocht om hier in hemelsnaam mee akkoord te gaan... Nou leuk je kan een schot tot 190km vrij precies afvuren... Gek he, dat we als Westerse landen steeds minder op de mat kunnen brengen als we dit soort ''projecten'' serieus ten uitvoer gaan leggen?  :dead:

Compleet mislukt project net als het schip waarvoor dit is bedoeld.
Financieel niet inzetbaar te houden en te duur om aantallen van betekenis aan te schaffen.

Ik ben dan ook benieuwd wat de Fregatten variant van het LCS gaat brengen, persoonlijk zou ik gekozen hebben voor een volledig nieuw ontwerp.

Vwb de Zumwalt's... hopelijk worden de problemen tzt met een rail-gun opgelost.

Als missile truck voor de USN hoor ik voorzichtig geluiden om San Antonio-class aan te bieden als platform, wellicht een betere optie dan de Zumwalts.

Is inderdaad de vraag. Nu zou je zeggen dat ze het ooit wel zouden leren, na de Virginia en Ticonderoga toch weer met een Zumwalt aan komen zetten.
De Burkes zijn wel zeer capabel, maar hebben een kort bereik, en zijn ouderwets in vergelijking met hun Europese tegenhangers. Ook zijn ze gewoon te duur om massa mee te creëren. Hopen dat het LCS fregat wat op gaat leveren, die Zumwalt wordt het in ieder geval niet. 22 miljard voor 3 van die dingen!

Idd,de "Burkes" zoals ze nu varen zijn eigenlijk(zoals iedereen hiero weet)oude ontwerpen die iedere keer "geupgraded"zijn nu de Flight ll (geloof ik)maar blijven in de basis natuurlijk 't zelfde(rompvorm)
Ik snap dan ook echt niet waarom de USA nu met van die "star wars"achtige schepen komt die naar blijkt(testen en in 't gebruik)gewoon niet "deliveren",maar als ik er over nadenk schiet me er nog eentje te binnen(F-35)
Dus als we 't traject van deze moeten toepassen(F-35)op die nieuwe schepen gaat 't ze nog belachelijk veel geld kosten om deze maar enig zins in de buurt te laten komen van de voorop gestelde eisen/doelen.
Schijnbaar houden ze daar van kapitaal vernietiging alles in de naam van "We can" :hrmph:

Wat ik ook niet begrijp(logisch denkend)is dat de USA gewoon niet gaat kijken wat er te krijgen is(zoals gezegd er zijn veel modernere varianten te krijgen aan de andere kant van de plas)en deze ontwerpen dan eventueel koopt en zelf bouwt(kunnen ze weer effe upgraden,indien nodig)

Alles zal te maken hebben met 't superioriteits gevoel waar de USA geen gebrek aan heeft ten opzichte van andere landen en 't eigenlijke wantrouwen ten opzichte van sommigen.(mijn mening)

Ik zag van de week een docu die ging over de mogelijk komende oorlog tussen de USA en de "Peoples Republic" waarin dat een hoge defensie medewerker 't (in mijn ogen)perfect weergaf,hij zei:

"we moeten blijven ontwikkelen en bouwen willen we een voorsprong,technisch en numeriek,behouden over onze vijanden"(ging niet alleen over China en Rusland)Dit was in antwoord waarom de USA al die basissen heeft rondom China (en er zelfs nieuwe opengedaan heeft)en of dit niet juist voor escalaties zou kunnen zorgen(al die vliegtuigen/raketten/schepen/etc)

In antwoord op de uitleg van deze medewerker zei de vraag steller:"In plaats van ze automatisch als vijanden te bestempelen zou je ze ook gewoon kunnen bekijken als landen"

Kijk dit soort reacties(antwoorden)daar hou ik van,getuigd van enige intelligentie(in mijn ogen),ongeveer 't zelfde als 't antwoord van Ghandi op de vraag"what do you think of British civilazation?"

Antwoord:"I think it's a good idea"

De artillerie oorlog in Oekraine laat toch zien dat precisie en bereik wel degelijk zeer belangrijk zijn. Daarbij, wij hebben die nauwkeurigheid ook nodig omdat er minder tolerantie is voor burgerdoden. Natuurlijk zouden wij ook goedkope Qassam raketten kunnen gebruiken, als je doelwit een willekeurige plek in een stad is. Of Vaatbommen, effectief en zeer goedkoop.

Keel laid for final USN Zumwalt destroyer

Anika Torruella, Washington, DC - IHS Jane's Defence Weekly - 03 February 2017

The keel of the US Navy's (USN's) third and final Zumwalt-class destroyer, the future USS Lyndon B Johnson (DDG 1002), was laid on 30 January at General Dynamics-Bath Iron Works shipyard in Bath, Maine.

Captain Kevin Smith, the DDG 1000 program manager, said in a statement that the future vessel was 60% complete as "advanced modular shipbuilding allows fabrication of the ship to begin months in advance". All 94 units are under construction with the steel deckhouse complete.

Lyndon B Johnson is the final ship in the Zumwalt class, which is based around an electric propulsion system, tumblehome hull, 155 mm Advanced Gun System (AGS), stealth design, dual band radar, automatic fire suppression system, and an electric integrated power system that generates approximately 78 MW for future technology such as electric rail guns, direct energy weapons, more powerful radar, or increased machine automation.

22 miljard voor 3 schepen, met beperkte capaciteiten en waar ze dus nu maar een rol voor gaan verzinnen.
Maargoed, de rol  van arsenaal schip zat er al even aan te komen. Eigenlijk gaan de schepen dus doen waar ze in eerste instantie voor ontworpen zijn.

Dat is zo ongeveer de boodschap, een soort van mini BB, maar dan in 2020 jasje zonder al te veel incasseringsvermogen, wel een schip die graag in je TG/TG zou willen hebben.

Ik denk dat ze daar stilaan tot de conclusie komen dat de laatste succesvolle klasse die ze daar gebouwd hebben de Arleigh Burke is (en gelukkig bouwen ze die nog steeds).
- Zumwalts...
- beide LCS
Gedaan met "think outside the box"... Gewoon iets meer traditioneel ontwerpen en bouwen...

Groot gelijk trouwens met de stelling in het artikel dat ze reeds over arsenaal-schepen beschikken... Ze zijn zelfs nog stealthier: SSGNs...

The Navy has a new vision for what its enormous high-tech destroyers will do: Killing enemy warships at extended ranges.

The Navy is asking Congress to fund a conversion of its 600-foot stealth destroyers from primarily a land attack ship to an anti-surface, offensive strike platform, according to budget documents released Feb. 12.

The service's 2019 budget request includes a request for $89.7 million to transform its Zumwalt-class destroyers by integrating Raytheon's long-range SM-6 missile, which can dual hat as both an anti-air and anti-surface missile, as well as its Maritime Strike variant of the Tomahawk missile.


Conclusie voor de USN is dus voor long range attack tegen "vijandelijke"schepen dat de keuze dan valt op SM-6 en Tomahawk

idd, precies !!
Ik zou dit ook voor onze fregatten adviseren.

Ik denk dat op termijn de Tomahawks weer vervangen worden door LRASM, maar omdat er nog zoveel Tomahawks in "stock" zijn en ook nog steeds doeltreffend zijn, worden deze eerst nog gebruikt.

Nederland heeft nu al meerdere keren een keus voor aanschaf van Tomahawks laten horen, nu doorzetten. Al zou je je ze eerst alleen op de LCF's plaatsen en de MF vervangers met SM-6 en NSM. Maar het liefst zie ik op alle fregatten Tomahawks ivm het bereik en punch. Dit geeft als afschikking en beschermings-/aanvals middel zoveel meerwaarde aan het fregat.

Reken er maar op dat een groot deel van wat je doet met de NSM afgedaan kan worden. Daarbij moet ik zeggen dat ik meer vertrouwen heb in de vaardigheid van een NSM dan van een tomahawk om door de verdediging van een kapitaal doel te komen. Een mooie toevoeging zeker. Maar m.i. verre van ideaal.

Vandaar dat men nu ook bezig met de ontwikkeling van een Tomahawk opvolger.

Het is mooi dat de NSM een groot deel van bedreigingen kan uitschakelen,  is ook een goedkoper dan een T'hawk, maar .... Reken er maar op dat landen als Rusland, China .., niet stil zitten. Zij zijn het bereik van hun raketten nu al flink aan het vergroten. Dan heeft de NSM tekorte benen.
Misschien dan maar een combi, maar zo'n combi vraagt ook meer capaciteit van VLS lanceersystemen, dus meer aantallen.

De Amerikanen testen ook de NSM, dus weten alles van hun capaciteiten.  Maar beslissen wel om T'hawks op hun stealth destroyer te plaarsen, zegt toch ook iets.....

Een combinatie kan ook bestaan uit topdeck NSM en VLS Tomahawks.Dit probleem hebben de Yanks niet bij de DDG1000 maar wij wel bijvoorbeeld op de vMFF's.

De ami's hebben al tomahawks. Dus Is het een goedkope oplossing.

Wij hebben ze niet, en voor we er dus 30 jaar mee rondvaren kunnen we beter iets kopen wat nu al effectief is.

Daarbij, met die afstanden wordt doelinfo heel belangrijk. Zouden wij missiles afvuren op coördinaten in Noorwegen, verkregen van een Deens schip via een Brits HQ?

Voordat we dit soort capaciteiten aanschaffen moeten we ook zeker investeren in MPA's, nucleaire onderzeeërs en vliegdekschepen.

Maargoed, buiten kijf dat ASuW leeft. En ook in Europa moeten we over andere zaken dan swarm attacks en SBIED's  gaan denken.

Voor SWARM attack's zou ik kiezen voor een systeem zoals de LCS-intergrated surface warfare system op basis van de hellfire, HIER  (https://www.lockheedmartin.com/content/dam/lockheed/data/ms2/documents/launchers/LCS-Integrated-Surface-Warfare-System-brochure.pdf)de brochure van Lockheed Martin. En dat in combinatie met het kanon op de boeg en de verschillende kleinere kaliber wapens (30 mm / 12,7 mm).

Verschil is niet echt aanwezig alleen dat de Amerikanen dit systeem wat verder hebben door ontwikkeld en ze lanceren vanuit een VLS. De Brimstone Sea zit in een decklauncher.
Het grote verschil zit in de vorm van lancering:
- US : VLS 24 cells per blok
- UK : Decklauncher met 6 raketten per launcher.

Verder zijn de verschillen zo klein, brimstone heeft een 20km+ bereik en de hellfire VLS 22 km dat is natuurlijk maar een klein verschil.

Guided-missile destroyer USS Zumwalt (DDG 1000) departed San Diego for its first operational underway, the US Navy announced on March 8, 2019.

"Zumwalt is designed for stealth," said Capt. Andrew Carlson, the ship's commanding officer. "This aids her role as a multi-mission surface combatant and improves the fleet commander's options for delivery of naval combat power to meet the Navy's emergent mission requirements."

Zumwalt's crew recently completed a post-delivery maintenance availability designed to thoroughly evaluate the ship's systems and equipment to include radars and engineering plant.

"My crew has been looking forward to continued testing and operations at sea, leveraging the newly installed capabilities of this platform," said Carlson. "Our primary focus is executing a safe underway, while building both competence and confidence in operating Zumwalt across the spectrum of naval warfare."

Zumwalt is under operational control of U.S. 3rd Fleet. Third Fleet leads naval forces in the Pacific and provides the realistic, relevant training necessary for an effective global Navy. Third Fleet coordinates with U.S. 7th Fleet to plan and execute missions based on their complementary strengths to promote ongoing peace, security, and stability throughout the entire Pacific theater of operations.

The nearly 16,000-ton Zumwalt was built by General Dynamics Bath Iron Works in Bath, Maine. The ship is 190 meters in length, has a beam of 24.6 meters, and a navigational draft of 8.4 meters. The ship is powered by two Rolls-Royce main turbine generators, two Rolls-Royce auxiliary turbine generators, two 34.6 MW advanced induction motors to speeds up to 30-plus knots.

The USS Zumwalt includes new technologies and will serve as a multi-mission platform capable of operating as an integral part of naval, joint or combined maritime forces. The Zumwalt-class fields a considerably larger flight deck and has capacity for two MH-60R and three VTOL UAVs to execute a wider array of surface, aviation, and undersea missions that deliver more manpower, firepower, and computing power to the fight. The Zumwalt's Vertical Launch System (VLS) features cells physically larger than similar cells on today's ships, allowing this class to fire larger and more advanced land and anti-ship missiles in the future.

The US Navy is eyeing a big change to its new stealth destroyers

NATIONAL HARBOR, Md. — The U.S. Navy is considering a significant change to its new stealth destroyers, one driven by the change of mission announced in last year's budget documents, the head of the program said May 7 at the Sea-Air-Space conference.

The service has been struggling to find a use for the ship's advanced gun system — the largest of its type fielded by the service since World War II — and now is considering stripping them off the platform entirely, said Capt. Kevin Smith, the DDG-1000 program manager at Program Executive Officer Ships.

The Navy sidelined the guns after the service truncated the buy to just three ships, and after the ammunition, called the Long-Range Land-Attack Projectile, ballooned in price to more than $800,000 per round.

"The guns are in layup," Smith said. "We're waiting for that bullet to come around that will give us the most range possible. But given that that is offensive surface strike, we're going to look at other capabilities potentially that we could use in that volume."

The ships shifted missions from land attack to ship-hunting and -killing last year. The Navy is integrating the SM-6 missile, which has a surface-attack mode, and are integrating the maritime strike Tomahawk to fill out the new capabilities.

In April testimony, the Navy's top requirements officer, Vice Adm. William Merz, told Congress that the slow development of the Advanced Gun System was holding back the Zumwalt.

"Even at the high cost, we still weren't really getting what we had asked for," he said. "So what we've elected to do is to separate the gun effort from the ship effort because we really got to the point where now we're holding up the ship."

The Navy has touted the ship's excess space, weight, power and cooling as advantages the service would want throughout the ship's life. Everything from directed energy and electromagnetic rail guns to electronic warfare equipment has been floated as add-ons to the Zumwalt-class destroyers.

The Navy got in its present pickle with the 155mm/.62-caliber gun with automated magazine and handling system because the service cut the buy from 28 ships, to seven, and finally to three.

The AGS was developed specifically for the Zumwalt class, as was the LRLAP round it was intended to shoot. There was no backup plan, so when the buy went from 28 to three, the costs remained static, driving the price of the rounds through the roof.

The program itself is coming along, said Smith.

The Zumwalt is going through trials as its combat system installation wraps up; the Michael Monsoor is heading into the yards for its combat system installation; and the Lyndon B. Johnson is nearly 85 percent complete.

The remaining work on Johnson involves running cables, painting spaces and otherwise putting the finishing touches on the ship. The ship will then leave Bath, Maine, and head toward its home port of San Diego, California.

"We're going to energize high voltage in September, lighting off the generators in the spring, then we'll be going to test and activation for the [hull, mechanical and electrical systems], trials in the fall, then delivery."

US Navy accepts destroyer Zumwalt delivery as service faces surface fire support shortfall

Michael Fabey, Washington, DC - Jane's Navy International
27 April 2020

The US Navy (USN) took delivery of guided-missile destroyer USS Zumwalt (DDG 1000) on 24 April, officially joining the US Pacific Fleet battle force assigned to Surface Development Squadron One, where the ship will eventually help develop new warfighting capabilities and rapid development and validation of operational tactics, techniques, and procedures.

It is a different role for a ship class initially and specifically designed to provide fire support - whose first Operational Requirements Document (ORD) values included an Advanced Gun System firing Long Range Land Attack Projectiles (LRLAP) - to address a land-attack gap, which needs to still be addressed.

What should become of the Zumwalt class? The US Navy has some big ideas.

The U.S. Navy is exploring a major ship alteration for its three stealth destroyers that would further drive up the cost of the platform but could deliver a radical new hypersonic capability in the ongoing naval competition with China  in the western Pacific.

In a solicitation posted March 18, the Navy asked industry for ideas on how to reconfigure the Zumwalt class to host larger hypersonic missiles of a size that would not fit in the vertical launch system tubes currently installed on the ships. The service also wants that business to provide the missiles and supporting software and technology to support the missiles.

Specifically, the Navy is looking for ideas about installing an "advanced payload module" that can support the Navy's conventional prompt strike missiles "in a three-pack configuration," according to the notice.

Two sources familiar with discussions around the future of the Zumwalt class said it would be possible to replace the idle Advanced Gun System – the original raison d'être of the class designed to support Marine landings with gunfire support from well over the horizon – with the desired payload module supporting hypersonic missiles. Experts said that doing so would transform the DDG-1000s from ships in search of a mission into powerful conventional deterrent in the Indo-Pacific region.

..../...

The idea then evolved into using Zumwalt as a surface ship killer, which has now evolved again into adding a module with conventional prompt strike hypersonic missiles to the hull. The after-market payload module is necessary because the conventional prompt strike missiles are at least 30 inches in diameter, and the current 80-cell VLS launcher on the DDG-1000 design, while larger than the standard Mark 41 VLS on the cruisers and destroyers, maxes out at missiles that are 28 inches in diameter.
