Ik was laatst bij MARIN voor testen met nieuwe ASWF boot. Durf wel te stellen dat we over unieke kennis beschikken om ontwerpen tot succes te maken.

Dit betekend dus dat het romp ontwerp (zo goed als) definitief klaar is? Dan mag ik er ook vanuit gaan dat we in niet al te lange tijd stappen gaan zien zoals contract ondertekening. :silent:

UK selects Team Resolute to build three Fleet Solid Support Ships

According to information published by the UK MoD on November 16, 2022, British-led Team Resolute, comprising BMT, Harland & Wolff, and Navantia UK, has been appointed as the preferred bidder to deliver three crucial support ships to the Royal Fleet Auxiliary (RFA).



The ?1.6 billion contract (before inflation) to manufacture the vessels providing munitions, stores, and provisions to the Royal Navy?s aircraft carriers, destroyers and frigates deployed at sea, is subject to HM Treasury and Ministerial approval.

Pledging to invest ?77 million in shipyard infrastructure to support the British shipbuilding sector, they aim to create one of the most advanced yards in the UK, significant for future export and domestic shipbuilding and offshore opportunities.

The proposal pledges that the entire final assembly for all three ships will be completed at Harland & Wolff?s shipyard in Belfast, with the three 216-metre-long vessels ? each the length of two Premier League football pitches ? to be built to Bath-based BMT?s entirely British design.

Under the contract, the majority of the blocks and modules for the ships would be constructed at Harland & Wolff?s facilities in Belfast and Appledore, with components to be manufactured in their other delivery centres in Methil and Arnish. This programme, which would also support a significant British-based supply chain, would be undertaken in collaboration with internationally renowned shipbuilder, Navantia.

Build work would also take place at Navantia?s shipyard in Cadiz in Spain, in a collaboration that allows for key skills and technology transfer from a world-leading auxiliary shipbuilder.

Delivering on ambitions to bolster UK shipbuilding as laid out in the National Shipbuilding Strategy Refresh, the contract aims to deliver significant capital investment in the UK while providing ships which are essential to the Carrier-led Maritime Strike Group.

The ships will be the second longest UK military vessels behind the two Queen Elizabeth-class aircraft carriers. They will have commonality with the RFA?s Tide class fleet tankers, also built to a British BMT design.

In the proposal, the majority of the three ships? build would take place in the UK, and the contract will increase industrial productivity, develop the domestic supply chain and workforce while improving the industry?s environmental sustainability.

Production is due to start in 2025 and all three support ships are expected to be operational by 2032. The manufacture contract is due to be awarded by DE&S by the first quarter of 2023, subject to completion of a successful preferred bidder stage and final approvals.

Dat is onhoudbaar.
De Chinezen produceren je er op elk vlak uit. Zulke schepen bouwen gaat de industri?le edge niet geven.
Dat vraag ik me af. Kwantitatief ja, maar levert 1 Chinees schip de zelfde kwaliteiten als een westers schip?
Zorgwekkend is het wel. Dit zijn de vruchten van de westerse welvaart. Iedereen heeft een hogere levensstandaard dus produceren we duurder. We geven dan ook veel meer om luxe en verzorging dan om onze veiligheid. Resultaat is dat daar meer financi?le middelen heen vloeien dan dat het geval is in oa China.

Next-gen destroyer?s price tag could be $1B more than Navy?s estimates: CBO

The US Navy?s next-generation destroyer, dubbed DDG(X), might cost roughly $1 billion more per hull than the service?s internal projections are forecasting, a non-partisan government watchdog has concluded.

That analysis is from the Congressional Budget Office?s annual report assessing the costs of the Navy?s future shipbuilding plans. The report, published on Nov. 11, found the service?s future destroyer will cost between $3.1 billion and $3.4 billion per ship, with anywhere between 29 and 47 vessels planned to be purchased after production begins in 2030. Meanwhile, the program as a whole, starting this year and running through 2052, would cost somewhere between $99 billion and $146 billion, the watchdog estimates.

By contrast, the Navy?s internal projections show each new ship costing between $2.3 billion and $2.4 billion depending on which version of the service?s 30-year long-term shipbuilding plan lawmakers pursue.

?Overall, the program represents roughly 30 percent to 40 percent of the difference between the Navy?s and CBO?s estimates of the total cost of the alternatives in the 2023 shipbuilding plan,? according to the new report. ?The uncertainty about the ultimate size and capabilities of the next-generation destroyer suggests that its final cost could differ substantially from both the Navy?s and CBO?s estimates.?

The report represents a first glimpse into the potential costs of a nascent shipbuilding program with big shoes to fill. The Navy earlier this year during the Surface Navy Association?s annual symposium provided an initial overview of what the service ? alongside the two private shipyards primarily responsible for building destroyers, HII and General Dynamics Bath Iron Works ? have in mind for the next-generation destroyer.

DDG(X) will follow the service?s workhorse ship, the Arleigh Burke class, a vessel senior Navy officials have repeatedly stressed has already been been tightly packed with the best technology the service has at its disposal.

Historically, CBO routinely projects higher shipbuilding costs than the Navy. The reason for this is mostly due to the assumptions analysts must make when they consider the costs of materials, rates of inflation, levels of commonality among older vessels as well as a host of other variables. The further out construction remains, the more difficult it is to create a precise estimates.

The Navy, which has to defend its budget proposals to Congress every year, often provides more optimistic estimates than CBO, which has earned itself a positive reputation among lawmakers who see it as an objective third party scorekeeper.

Also impacting this year?s report is the unusual step the Navy took when it offered lawmakers three different long-term shipbuilding plans, rather than laying out a unified vision for the future force. The Navy defended that decision as necessary given the ?uncertainty? and ?fiscal reality? the service faces.

Nonetheless, the total quantity and rate at which ships are built have a direct impact on their cost, which means the precise cost of DDG(X) will necessarily differ depending upon which of the Navy?s ?alternatives? Congress chooses.

?To fund the DDG(X) program from 2023 to 2052, the Navy would need $125 billion under alternative 1, $99 billion under alternative 2, and $146 billion under alternative 3,? according to CBO.

Hull Vane B.V. Presents Its Innovative Products To The Hellenic Navy

At MAST Med 2022 conference and exhibition that took place in Athens, Greece in 2-4 November 2022, the Dutch company Hull Vane B.V. exhibited its Hull Vane solutions for naval and coast guard vessels.

The Hull Vane? is a hydrodynamic wing attached to a ship?s stern. The company met also with Hellenic Navy officers at the Papagos camp (Pentagon) in Athens. Naval News attended MAST Med 2022 and interviewed Bruno Bouckaert, Sales Director at Hull Vane B.V.

NN: Could you tell us a bit about your technology?

BB: We produce an energy-saving and seakeeping device for medium-speed ships, called Hull Vane?. The Hull Vane recovers energy from the stern wave, making ships more efficient, more silent and faster, while being less visible. It also reduces ship motions in waves. Fuel consumption and CO2 emissions are typically reduced by 10 to 20% on naval ships. It is a proven solution, both in terms of performance and longevity, and can be compared with the bulbous bow in many respects. It is passive, needs to be designed and built well and is basically fit-and-forget. The main difference with the bulbous bow is that Hull Vane? is a patented solution, so it can be only acquired from us. We also have an active version, called Dynamic Hull Vane, which is particularly suitable for vessels in the size range 20-60 m such as patrol vessels, mine countermeasure vessels and unmanned surface vessels.

NN: You have exhibited at Posidonia and at the MAST Conference, both in Athens this year. Why is Greece so important for Hull Vane BV?

BB: The Greek, like the Dutch, have saltwater running through their veins. Both are seafaring countries with economies which depend a lot of safe seas. We see a great potential in Greece, on one side on the passenger vessels and yachts, but equally so for the Hellenic Navy and the Hellenic Coastguard. The Hellenic Navy has three very relevant programs at the moment, where Hull Vane could play a role: the FDI frigates built by Naval Group, the future corvette program, which is still in the bidding phase, and the midlife upgrade of the MEKO class frigates. We hope to do a retrofit on a smaller existing naval ship to familiarize the Hellenic Navy with Hull Vane? in the short term, so they can incorporate it in their future newbuilds. We had the pleasure to meet with the Minister of Migration, Mr. Notis Mitarachi, at the MAST exhibition, and he very quickly saw the potential of Hull Vane for the Hellenic Coast Guard fleet.


FDI tank test model fitted with a hull vane. This model was showcased during the Naval Group innovation days in 2021.

NN: Do you think there?s a high probability of success?

BB: Yes, we do. We have met with the naval architecture department of the Hellenic Navy in Athens, and they are very interested in applying the Hull Vane solution. The next step is finding the funds to do an installation. Hull Vane is an investment in a significant capability improvement, which pays for itself due to the energy savings provided, but it still needs to be acquired in the first place. We also expect that the European shipbuilders which have built ? or are building ? ships for the Hellenic Navy, such as Naval Group, Damen Naval and TKMS, will be interested to see which benefits Hull Vane can bring to their ships. With Damen Shipyards, we are working on a retrofit of a Hull Vane on one of the 108 m Holland Class Oceangoing Patrol Vessels, which will take place early 2023.

NN: If your technology has so many benefits, why isn?t everyone applying it already?

BB: That?s exactly what our customers ask, who have experienced the Hull Vane. Believe it or not, often even those who are not customers ? but should be ? ask us this question. In our eight years of experience with Hull Vane, having sold more than 60 units, we have found that the smaller the organisation, the easier it is to get Hull Vane implemented. Navies and naval shipbuilders are almost by definition large organisations, so this takes more time, but based on all the CFD studies and model tests we have done, we are absolutely certain that you will see very many Hull Vanes on naval ships in the future, just like you often see bulbous bows, fin stabilizers and the latest signature-reducing systems. Hull Vane performs all of those functions in one solution: resistance reduction, seakeeping improvement and signature reduction.

While a few years ago, fuel consumption was seen as not so relevant to defence, now it is widespread knowledge that dependency of fossil fuels is a liability for those countries which do not produce oil, and Hull Vane helps reducing this liability. We?ve seen the tanks stranded in Ukraine without fuel, and this can of course happen at sea as well during a conflict, when supply lines come under stress.



NN: Can you show anything about these CFD studies?

BB: Most of our work is under non-disclosure agreements of course, but you can find interesting studies regarding naval ships in the ?papers? section on our website. I would also recommend the video we made of the Hull Vane retrofit on the French patrol vessel Th?mis, as it show how Computational Fluid Dynamics predictions correspond with what you see (and hear) at full scale. It shows very well the difference before and after installation.

https://www.youtube.com/watch?v=VGjt_y0Scjo

This vessel has a hull shape and a speed range which is very typical for naval ships, and indeed many of our CFD studies show similar results, but with somewhat lower resistance reduction percentages (8-20%) on more slender hulls such as frigates, when comparing to beamier OPVs (10-25%).

NN: We have seen a tanktesting model of the FDI with Hull Vane? at the Naval Innovation Days of Naval Group. Can you tell us anything more about this project?

BB: Due to NDA?s, I can?t comment on any specifics, other than that I was there as well and it was a great honour to talk about our technology with the French Minister of Defence. We have a good relationship with Naval Group, which can be seen in the paper which we published with them, and which is available on our website. They also presented at Euronaval 2022 their concept ship ?Blue Shark? with a Hull Vane? for improved signature reduction, stability and endurance. I know that they are very keen to move from model tests to a full scale application, but of course they need a client willing to innovate with them.

NN: Any final comments?

BB: We know from military history that the speed at which innovations can be implemented is a determining factor in a global conflict. During peace time, our navies do a lot of training missions, and rightfully so. Wouldn?t it be great if we would also train our defence material organisations by giving a specific task, a budget and a timeframe? We have possible Hull Vane projects on the shelf for every European Navy and Coastguard, and many others. It is exceptional for us to receive a direct phone call from a navy?s logistic department, while it should be very normal. We are ready for it!

Germans circle navy?s corvette warship plan

Germany?s biggest shipbuilder has signalled its interest in mooted plans to build a fleet of corvettes, as the Australian navy looks to rapidly boost the strike capability of its warships in response to China?s military build up.

The Australian Financial Review understands executives from shipbuilder TKMS ? a subsidiary of German industrial powerhouse ThyssenKrupp ? are seeking meetings with navy officials this week to discuss the potential project.

https://www.afr.com/politics/federal/germans-circle-navy-s-corvette-warship-plan-20221107-p5bw4u

Mogelijk een (grote) wijziging in het Australische OPV project, men ziet nu in dat korvetten in de huidige situatie verstandiger is dan OPV's. Volgens het artikel is een van de opties die bekeken (kan) word(en) het afbouwen van 6 van de 12 OPV's en ze overdragen aan de Kustwacht. In ruil voor de OPV's zou de RAN dan 12 korvetten laten bouwen door Lurssen.

Een andere optie volgens het artikel is een aanbesteding waarna ook andere werven weer kunnen mee doen. Dan zouden er ook kansen zijn voor Damen met haar lokale partner Austal.

Australia reviewing proposals to build new corvette-type surface combatant fleet

The Australian Department of Defence (DoD) was reportedly reviewing a plan to procure a new fleet of small surface combatants to provide the Royal Australian Navy (RAN) with increased combat capabilities in response to the heightened security threats in the region.

Media outlet The Australian reported that a proposal to procure between 10 to 12 corvette-type warships with anti-surface warfare (ASuW) and anti-submarine warfare (ASW) capabilities, with a proposed cost between A$5 to A$6 billion (US$3.2 to US$3.8 billion).

The plan was said to have been raised after a realisation with the Australian DoD that the Royal Australian Navy's upcoming Arufara-class offshore patrol vessels designed by Germany's Luerssen are no longer sufficient in providing security against a growing strength and reach of China's People's Liberation Army Navy (PLAN), China Coast Guard (CCG) and its Maritime Militia forces.

The introduction of new missile and torpedo-armed corvettes would provide greater firepower and combat capability to meet future threats, especially in defending Australian territorial and Exclusive Economic Zone waters, as well as sea lanes and areas of interest.

The report also mentioned that the DoD is looking at Luerssen's corvette models, which include the K130 design used on the Braunschweig-class corvette of the German Navy, and the C90 design which is used for corvettes being built for the Bulgarian Navy.

Both designs are larger than the Arufara-class OPV being built for the Royal Australian Navy, and are armed with surface-to-surface and surface-to-air missiles, torpedoes, and multiple medium-caliber naval guns.

A proposal to up-arm the Arufara-class with heavier weaponry was also raised as an option, although there are also plans to transfer the offshore patrol vessels to the Australian Border Force, which is equivalent to a Coast Guard force of other countries.

Should the plan gets green light, the corvettes would be built in Australia, or could be a hybrid construction project between Luerssen's shipyards in Germany and Australian.

The first corvette is expected to be completed by 2028, with additional ships produced and completed every 10 months, and are targeted to cost as low as A$500 million each, far cheaper than Australia's recent warship acquisition and construction projects.

Dat zijn uiteraard twee andere verhalen. Ik denk dat een dergelijk systeem ook noodzaak is/wordt tegen toekomstige dreigingen. Kinetische middelen hebben ook zo hun beperking.

Wat te doen met een goedkopen wegwerp drone zwerm van 200 exemplaren die jou als doel hebben?
Ik kan me toch niet aan de indruk onttrekken dat ??n of twee GAU-8 kanonnen, gekoppeld aan een leuke radar, zo'n zwerm wel in ??n keer aan gort schieten. Hebben we hier al niet een soortgelijk systeem?

Ik snap niks van de huidige ontwikkelingen het wiel opnieuw uit te vinden. Is het een kostending ofzo?

Nou, ik heb in het ASWF topic een schets gepost van wat naar mijn idee een goede CIWS setup is voor het ASWF daar kunnen zonder problemen nog 2 HEL's en stoorzenders bij wat mij betreft.
Gelukkig is het ASWF ontwerp nog niet definitief (voor zover bekend) en het AWWF is nog maar in het begin stadium waardoor dit soort dingen nog mee kunnen.

De A300PL die hieronder staat geeft een goed beeld van wat er mogelijk is, en ja dit kan ook (mits er goede voorzieningen voor aanwezig zijn) op de ASWF en AWWF gebeuren. Simpel gezegd, als er op de boeg van het ASWF geen ruimte meer is voor extra VLS cellen zou ik het geen probleem vinden als we het schip (nog) iets verlengen midscheeps waardoor er nog 32 extra Mk56 VLS cellen (FFBNW voor Belgie?) kwijt kunnen dat geeft toch 32 extra ESSM's bovenop de 32/64 die er nu in gaan.
