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.

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.

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."

USS Zumwalt heads out for its first operational underway

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.

Dan ben ik wel benieuwd naar een vergelijk tussen de Hellfire en Brimstone Sea Spear

http://www.mbda-systems.com/brimstone-solution/brimstone-sea-spear/

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.

Voor SWARM attack's zou ik kiezen voor een systeem zoals de LCS-intergrated surface warfare system op basis van de hellfire, HIER 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).

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.
