Zoiets hoort eigenlijk thuis in het 'maanbasis-type'-projecten.
Marines op zoek naar OPV-achtige schepen zullen gewoon OPV's bestellen. En al zeker deze die geen ervaring hebben met subs.
En deze die wel ervaring hebben met subs, zullen gewoon subs kopen.

Science-fiction of Fantasy.

En toch kan ik me wel bepaalde missies en/of missie gebieden voorstellen waar dit nuttig kan zijn. Bijvoorbeeld de Zwarte Zee of de Oostzee. Dit soort boten/schepen kun je ook niet vergelijken met een echte onderzeeër. Dit gaat terug in de tijd dat men het nog duikboten kon noemen en ze slechts korte periodes onderwater verbleven.

Een interessant concept, de vraag is of het ooit gebouwd gaat worden al denk ik van niet.

Rubin Design Bureau Unveils New Version Of Its Submersible Patrol Ship  (  :hrmph: .... tja.. )


The Border and Offshore Submersible Sentry (BOSS) patrol ship that combines the benefits of a submarine and a surface patrol ship.

Russia's Rubin Design Bureau presents the second version of its Border and Offshore Submersible Sentry (BOSS) patrol ship that combines the benefits of a submarine and a surface patrol ship.

Rubin Design Bureau press release

It is the largest version with 72 m length and surface displacement about 1300 t. Large dimensions bring more capabilities. New lines with wave-piercing bow and tumblehome hull reduce roll, make ship more stable weapon platform and reduce radar signature as well. Sonar array in bow bulb works in better conditions and the bulb itself reduces surface drag. High-power propulsion system allows speed up to 21 kt.

This version is maximally armed with autocannon, two guided-missile launchers and four 324 mm torpedo tubes. Such weapon package makes BOSS a formidable enemy for even much larger ships. As in other versions, this ship has two pressure-proof multifunctional hangars for boarding teams boats and equipment, unmanned aerial vehicles or other payload. Both radar and sonar can be used for search and target acquisition, allowing discreet detection and approach.



The ship can be used in anti-submarine exercises and training of crews for classical submarines. The cruising range is up to 4000 miles at 10 kt, and can be increased on Customer's request.

As military budgets decrease due to pandemia and its consequences, Navies' demand shifts to multifunctional ships. Our response to this challenge is a combination of surface and underwater capabilities in the BOSS project. Due to such synthesis the ship intended for peacetime use retains its relevance as a combat unit in case of a conflict escalation. Moreover, the diving capability allows BOSS to fulfill typical patrol duties in its own innovative ways, some of this ways being cheaper and simpler.



The BOSS project is developed as adaptable, its modifications and variable characteristics allow to offer the ship that corresponds to the Customer's needs, conditions and capabilities to the maximum eхtent.

Rubin Design Bureau is among world leaders in the design of nuclear and conventional submarines and the largest marine engineering company offering design services in Russia. 1065 submarines in 120 years of our work have been built to Rubin designs, including 949 submarines commissioned by the Russian Navy. Totally 116 submarines designed by Rubin have been exported to 16 countries.

Rubin also develops marine robotic systems and designs the facilities for offshore oil and gas field development. The company is a subsidiary of the state-owned United Shipbuilding Corporation.

Israel's Submarine Secret: New Dolphin-IIs Could Have VLS

The Israeli Navy maintains a high level of secrecy surrounding its submarine capabilities. And the latest boat, the INS Dragon, is more secretive than most. This may be driven by new weapon capabilities, possibly including a vertical launch system (VLS).


https://www.navalnews.com/wp-content/uploads/2022/01/Israeli-Navy-Dolphin-II-Submarine.jpg

Israel's latest Dolphin Class submarine, INS Dragon ('Drakon' in Hebrew) which is under sea trials in Kiel, Germany, is extremely camera shy. It is possible that the submarine may have been increased in length compared to earlier boats of the same class. The same could be true for the follow-on 3 boats currently on order. This would match rumors that the new submarine has been fitted with a vertical launch system (VLS).

Israeli media reported on January 18 that the cost of Israel's submarines has increased significantly. While reports cover the three follow-on boats, this resonates with the increased size and capability of the submarines from INS Dragon forward. It is the latest in a chain of very small hints about Israel's newest submarines.

A VLS would imply a significant leap in capabilities. Israel's Dolphin-I and Dolphin-II class submarines are already equipped with torpedoes and cruise missiles. But they are shot through the torpedo tubes. The inclusion of a VLS implies either more weapons, or our bet, new weapons.

If correct, the Israeli submarine is only the second modern AIP equipped submarine in the world designed with this capability. The first being the South Korean KSS-III class which has only recently entered service. The two classes can be seen as part of a wider trend to fit VLS on conventionally powered submarines.

HENSOLDT To Provide Optronics Suite For Type 212CD Submarines

Sensor solutions provider HENSOLDT is equipping the German-Norwegian submarine project U212 CD with a fully digital sensor suite. The optronics division of HENSOLDT has now received a corresponding order worth over 50 million euros from kta naval systems, a consortium of Kongsberg, ThyssenKrupp Marine Systeme and Atlas Elektronik.

Norwegian and German submarines to benefit from technological leap to fully digital sensor equipment

HENSOLDT press release

The order comprises six optronic systems, consisting of an OMS 150 optronic mast system, an OMS 300 and an i360°OS panoramic surveillance system for each of the six submarines of the Norwegian and German navies. With the twin optronic mast solution, the clients opted for the technological leap from the conventional, traditional direct view of a periscope system to a completely hull-penetrating digital system solution.

HENSOLDT Optronics Managing Director Andreas Hülle says: "This combination provides the new submarines with sensor equipment that combines the highest detection capabilities even in poor visibility with a high degree of automation, thus significantly improving the boats' ability to act and survive."

The combination of OMS 150 and OMS 300 is being commissioned for the first time for the U212 CD class. The OMS 150, in its multispectral version, will be used as a search and surveillance optronic mast. The OMS 300 stealth optronic mast takes over the so-called "attack" function. With the OMS 300, the developers at HENSOLDT have created an optronic mast that is difficult to detect visually and via radar, which significantly increases the safety of the crews. This multispectral optronic equipment provides the crew with the best visibility in all light and weather conditions, as well as a very wide range of operations. With this order from kta, HENSOLDT Optronics is further expanding its research and development in the field of optronic masts at the Oberkochen site.

Kongsberg to Provide Sonar and Navigation Systems for Type 212CD Submarines

Active sonar suite and bottom navigation technology from Kongsberg Maritime (KONGSBERG) has been selected for installation on Type 212CD class submarines for both the Norwegian and German navies.

Kongsberg press release

The contract was awarded through a comparative and thorough process governed by Kongsberg Thyssen Atlas JV (kta naval systems) and tkMS (thyssenKrupp marine systems) with other vendor(s).

The KONGSBERG technology package consists of SA9510S MKII Mine Avoidance and Navigation Sonars (MANS) plus a Bottom Navigation System (BNS) containing EM2040 MIL multibeam echo sounders and an EA640 echo sounder suite. These sensors provide valuable input to kta naval systems' ORCCA™ Navigation system to enable safe, indigenous submerged operation of the submarines.

ORCCA, the most modern combat system for non-nuclear submarines on the market, is the first of its kind in combining maximum adaptability with the highest level of IT security. It enables operators to conduct an integrated data analysis from a wide range of systems on board via one multifunctional console – and this in results in rapid, well-informed decision-making processes.

Thomas Hostvedt Dahle, Director of Sales for Naval Sonars, KONSGBERG, said:
Citaat"This contract is an important confirmation that KONGSBERG's knowledge, experience and past performance in underwater acoustics have made this Norwegian-made underwater technology a world-leading development for both the commercial and defence segments. As a former submariner I'm proud to take part in this program, and will look forward to supporting submarine operations for many years to come."

Brazil progresses nuclear submarine project

French shipbuilder Naval Group is providing technical assistance across all aspects of the future SSN except for the nuclear reactor.

On 25 November, Brazil signed a licence agreement to start building the hull of its future nuclear-powered submarine. Issuing the licence meets one of the programme prerequisites, allowing for a contract to be let and the start of hull production.

The nuclear submarine is part of Brazil's ambitious PROSUB project to develop and domestically build four diesel-electric powered Riachuelo-class submarines and the country's first nuclear-powered boat.

According to Shephard Defence Insight, the future SSN, Álvaro Alberto, is expected to be commissioned in 2034 and will likely cost $2.4 billion to produce.

In November 2020, the Brazilian Navy approved the basic design for the future SSN. The nominal timeline could see the country field a nuclear-powered submarine before Australia commissions its first planned SSNs under development following the signing of the AUKUS agreement.

In December 2020, Brazil launched its second Riachuelo-class submarine, Humaitá, at a ceremony attended by President Jair Bolsonaro.

Next Generation SSN(X) Attack Sub 'Is Going to Carry a Lot of Torpedoes,' Says Admiral

The next U.S. nuclear attack submarine must require less maintenance, be fast, quiet and packed with torpedoes, the service's director of undersea warfare said on Thursday.

The SSN(X) nuclear attack boat will be more focused on the war in blue water than the multi-mission Virginia-class submarines, which are designed to operate closer to shore for missions like signals intelligence and special operation missions.

"Virginia remains the most capable multi-mission submarine in the world – bar none," Rear Adm. Doug Perry, the director of the undersea warfare division on the chief of naval operations staff (OPNAV N97), said last week. "But we must maintain our undersea advantage by investing for future capabilities. And we know we need to start that work today to make sure we can deliver SSN(X) in time of need, and without lots of technical or schedule risk."

In 2019, the Congressional Budget Office estimated that the SSN(X) boats could cost up to $5.5 billion per hull. The current Virginia-class boats cost about $2.8 billion per hull, while the Block Vs with the 80-foot Virginia Payload Module will cost about $3.2 billion.

"The Navy indicates that the next-generation attack submarine should be faster, stealthier, and able to carry more torpedoes than the Virginia class—similar to the Seawolf-class submarine. CBO therefore assumed that the SSN(X) would be a Seawolf-sized SSN, which displaces about 9,100 tons when submerged, and would have an all-new design in keeping with the Navy's description of it as a fast, lethal next-generation attack submarine," the CBO wrote.

Before Virginia, the Navy developed the Sea Wolf-class to be a deep-diving submarine with a weapons room that can field about 50 torpedoes.

Perry said, in broad strokes, SSN(X) would take the heavily-armed Seawolf template, combine the stealthy technology developed for Virginia and keep the time in maintenance to a minimum.

Outside of a classified initial draft capabilities document, "we don't know the specific characteristics that will be in SSNs. But we do believe that the next submarine will have a large horizontal payload capacity. You can read that as it's going to carry a lot of torpedoes. And we know how to do that. It'll be fast. And it'll have acoustic superiority. That's both sensors to hear the other ships out there as well as stealth – staying quiet," Perry said.
"We know how to do all of these things, but we have to integrate them into one platform.
Speed and large payload? We did that on Seawolf, and we need to pull that forward to a modular construction submarine."

"The heavyweight torpedo will remain the weapon of choice for the submarine for this for the foreseeable future, primarily due to its inherent stealth, its destructive effects in the battlespace, and [it's] pretty difficult to defend against and it also [preserves] the stealth of launch platform," Perry said.

The development of the Navy's Acoustic Superiority Program began on Virginia-class USS South Dakota (SSN-790), which commissioned in 2019, Perry said. The package includes a large vertical array mounted on the hull just aft of the sail, a special exterior coating and machinery quieting improvements inside the boat.

Based on the timing of the construction of the Columbia-class, the new class would come just as the construction of the class of 12 nuclear ballistic missile submarines is ending in the 2040s and in the short term design work should begin soon.

"With Columbia 95 percent design complete, now is the time to begin transitioning that experienced design workforce," Perry said.
"Fielding any new class submarine is challenging, but we got to strike while the iron is hot."

The Virginia boats now – and the Columbia boats in the future – are built in a teaming arrangement between Huntington Ingalls Industries and General Dynamic Electric Boat. Each yard builds part of a boat and the components are barged to each yard for final assembly, with EB being the lead yard for the design of each class. Perry said that the workforce would be key to making SSN(X) affordable.

"This maintains a steady demand signal for the shipyard workforce, which is a key element of developing and sustaining a resilient submarine industrial base," Perry said.

The Navy is also considering how it will leverage unmanned undersea vehicles with its new class.

"We know the ability to influence the battlespace and leverage the seafloor is to get to the bottom of the ocean you will need UUVs," Perry said.
"That requires a submarine interface that will drive what SSN(X) has to be in terms of a dimension for an interface that will launch and recover [UUVs]. It may be a torpedo tube it may be something different."

On the other end of construction, the Navy is working to increase the amount of time the submarines can operate by reducing time in maintenance.

"SSN(X) has to have high operational availability, [we've] got to be able to keep that ship at sea. And that gets to sort of the class maintenance plan. We've learned a lot from operating [the Los Angeles class], then Seawolf and Virginia. We are analyzing those class maintenance plans with PEO Subs and making sure that the class maintenance plan we've come up with gives us the highest operational building availability possible," Perry said.
"That'll be really part of our calculus as we define the work through the capability development document and [requirements] process and defining what SSN(X) needs to be."
