Singapore's MRCV will use IFEP from GE Vernova

Illustrious contributor, Shawn Chung, has commented offline that the power type for Singapore's frigates are improving. The power types are progressing from Combined Diesel and Diesel (CODAD), in the current Formidable-class frigates, to Integrated Full Electric Propulsion (IFEP), in the Singapore Navy’s six-ship future frigate currently called the Multi-Role Combat Vessel (MRCV).

GE Vernova’s Power Conversion business has been awarded a contract by Singapore shipbuilder ST Engineering Marine Limited to supply its Ship’s Electric Grid with Integrated Full Electric Propulsion (IFEP) equipment for the MRCV program.

The MRCVs are being built by Saab, Odense and Singapore Technologies ST Engineering Marine Ltd's at Singapore's Shipyard probably drawing on the Absalon/Iver Huitfeldt designs. Back in 2020, when Pete posted about the MRCV, Shawn commented that his  personal favourite guess was that the future MRCVs would be based on the UK Type 26 design.

[Pete Comment: Australia as usual made a poor decision in actually choosing
UK BAE's underdeveloped Type 26 design. Like all RAN projects since 2010, the Hunter-class variant is late and overbudget. Not to be forgot BAE is the builder of the equally late overbudget Astute SSN. With some foreboding BAE has been chosen to design and mainly build the SSN-AUKUS. In contrast Singapore always chooses ships and subs more wisely and vastly more cheaply than Australia.] 

Back to Shawn's MRCV - So the MRCV now looks like it'll be related to the UK Type 31 [with the UK Type 31 due in service 2027] which is itself a derivative of the Danish Iver Huitfeldt-class frigate but larger. 

The power load for the 8,000 tonne MRCV will be quite high, as apart from a communication system that can simultaneously handle multiple drones (and recharge them), the class will also use large fixed array Sea Fire AESA radarthe larger variant for big frigates and destroyers (bigger than the Sea Fire 500 equipping the FDi) IFEP is still quite a cutting edge technology for naval ships.

FURTHER BACKGROUND

Gordon Arthur for Naval News, March 14, 2024 reported https://www.navalnews.com/naval-news/2024/03/singapore-cuts-steel-on-its-first-multirole-combat-vessel-mrcv/ in part:

“Singapore’s future class of Multirole Combat Vessels (MRCV) took a significant step forward on 8 March [2024], when ST Engineering Marine cut steel on the first of six vessels.”…

The MRCV design – resembling ST Engineering’s own Vanguard 130 concept (that is 130m long and displaces 5,000 tonnes) features an integrated mast, stern flight deck, helicopter hangar and twin stern ramps for deploying small craft. A strong candidate for the integrated mast must be the Saab Lightweight Integrated Mast (SLIM), since it is already employed on Singapore’s eight Independence-class vessels.

The MRCV will replace six 595-tonne Victory-class missile corvettes within the RSN, but Singapore’s MINDEF remains tight-lipped about exact specifications and equipment. However, it is obvious that the MRCVs will be far more capable and larger than the six-corvette Victory class that dates from the early 1990s.

Naval News learned from various industry sources during IMDEX Asia 2023 that the MRCV would have a displacement of around 8,000 tons and a crew complement of about 80 sailors, indicating a high level of automation in the platform. Naval News understand that the mothership vessels would feature: 

Leonardo’s 76mm naval gun in the STRALES variant;

·  MBDA’s VL MICA NG and Aster B1 NT air defence missiles;

·  ST Engineering / IAI Blue Spear anti-ship missiles;

·  Thales’ SeaFire multifunction radar (in four fixed array configuration as aboard
         the FDI frigate);

·  Safran’s PASEO XLR EO/IR system;

·  Safran’s NGDS decoy launching system.

The MRCV is set to become the first surface combatant fitted with a combination of ASTER and VL MICA missiles. The RSN is an existing user of both missiles: ASTER are fitted aboard the Formidable-class frigates while VL-MICA are fitted aboard the Littoral Mission Vessels.

The vessels are set to host, launch and recover ST Engineering’s VENUS family of unmanned surface vessels (USV), both in their mine warfare and maritime security variants. The MRCV will also accommodate a number of unmanned aerial vehicles (UAV).

During the naval defense event held in Singapore last year we also learned that competitions were still ongoing for the secondary gun systems (between Leonardo’s Hitrole and Rafael’s Typhoon), the sonar suite (between DSIT and Thales) and the torpedoes (between MU90 and A244 MOD.3 LWT), among other equipment.

Spoke at length with Col. (Ret) Chew (now working for SAAB) at Singapore Airshow 2024 - the guy who brought the LMV from nothing but an idea to a full operational squadron - while the LMV story is awe-inspiring from a project and people standpoint, he did also explain the MRCV model shown off at the SAAB booth. I don't know what is post-able even though it was a public event on the public day, so I will limit myself.

In essence, the model displayed at the SAAB booth is accurate since the general design work is finished. The model featured a SeaFire 4-panel multipurpose radar, a 76mm Strales A-gun (which he touted several advantages of beyond use as a CIWS, one traditional role of RSN's 76mm Super Rapids), 4x8 Sylver cells, autocannons to the rear and the big empty amidships deck just like on the Formidable class, which should be a clear hint as to intended capability.

Missile fit is as one would expect of a ship like that in 2024.

My interpretation is that MRCV is intended to have approximately a Formidable-class conventional "direct" combat capability, while accommodating large spaces for large numbers of unmanned assets to be launched and recovered, ranging from UAS, UUV, USVs and the ship's S-70 helicopters. The MRCVs will be a mothership of sorts in that way.

A partial photo of it can be seen here (not mine, not affiliated), bonus is Col. Chew in the background.

There ought to be more public photos of the model online since thousands of people were pointing and poking at it, but I can't seem to find any.

The MRCV is a very divergent derivative of the Iver-Huitfeldt/Absalon/Arrowhead 140/Type 31 class of ship.

Thanks retortPouch at 3/31/2024 4:02 PM

So the "LMV", you refer to, is the Independence-class littoral mission vessel of 1,200 tonnes, which Singapore, with its customary efficiency, building 8 https://en.wikipedia.org/wiki/Independence-class_littoral_mission_vessel

I'm confident that Singapore's future MRCV frigates (designed after Australia's Type 26 variant Hunters?) will be commissioned by Singapore before the Hunters.

That is Singapore will build the MRCVs in half the time and at less than half the cost of the Adelaide built Hunters (first to be commissioned in 2034 https://en.wikipedia.org/wiki/Hunter-class_frigate ).

Pete,

The LMVs are an interesting design - here's then LTC Chew briefing Naval Recognition about the LMV in 2017.
https://www.youtube.com/watch?v=Gw-2XdSxLpA

Notes:
1. For a 'stealth' design, the 76mm guns look like they older SR models.
2. Not ASM equipped, but I reckon there's mission module if there's a real need..
VL-MICA is actually a quite interesting weapon system, as the missiles come in IR or RF variants.

I expect the gun to be upgraded to Strales in the future, (I reckon this will be fleet wide upgrade) as the Red Sea issue has demonstrated how a non-state actor can use drone swarms.

Pete, I mentioned to you before that ST Marine is actually quite busy at this moment in time - they are conducting the MLU the Formidable class (delivery by 2028) while producing the MRCV (announced 2018, first delivery 2028), so there's obviously some factor to this 'hurried' timeline - the first Victory class MCV turns 40 in 2028.

Hi retortPouch at 3/31/2024 4:02 PM and Shawn C at 4/02/2024 2:58 AM

Thanks for the information on Singapore's LMV and MRCV.

I'll do an article on those ship classes next week.

Cheers Pete

Hi Pete, Shaun and TW,

@Shaun: I hear that the LMV class's 8 super rapidos were pulled off of the 8 Fearless Class PVs which did not get given the Sentinel class's afterlife: see the Bruneian Al Faruq, ex-Gallant

https://navyrecognition.com/images/stories/news/2023/october/Singapore_Navy_delivers_Fearless_class_patrol_vessel_Al_Faruq_to_Brunei.jpg

(as an aside, once the Sentinels are retired, the emergent 4-ship gap in the patrol fleet will be filled by the just-ordered Fassmer OPVs, re-mapping the roles of what used to be the patrol fleet.)

On its own, the super rapido, which achieves 0.3mrad (akin to 1 MOA) accuracy is thought of as sufficient for the CIWS role; indeed several intercepts in the Red Sea have recently been achieved with the 76mm HE-PFF. However, Strales increases the number of targets that can be engaged through time, since smaller salvos can be fired per target with a higher confidence of kill. Using Vulcano ammunition also reduces the number of rounds needed to be fired to score a meaningful hit on land; as can be seen from the recent conflict in Gaza, Israeli patrol boats needed to bracket and then adjust their fire on Hamas militants during the initial Hamas attack. Vulcano course-corrects to a target from an inertial or GPS reference, so that the uncertainty in own-firing position and mid-course positions can be greatly reduced.

The cost to that is adding a lot of complexity to an already complex and maintenance-intensive main gun system, possibly the most maintenance intensive thing aboard the RSN's vessels.

@Pete:
I suppose electoral dominance has allowed the incumbent Government to treat defence the same way as insurance - hold your nose and painfully pay about the same amount every year to maintain continuity. Defence spending in Singapore has actually halved as a proportion of GDP since 1990 - going from about 6% to below 3% last year. The current Minister for Defence has recently stated at the Budget that expenditure will be held at about 3%, in view of present realities.

That said, I think it is difficult to compare the efficiencies of the Hunter-class and the MRCV. Since MINDEF never publicly stated any concrete or official timelines (the project, as you may recall, has been talked about for a long while without anything concrete coming to light!), it is very hard to judge how "late" it is. Since MINDEF feels little pressure to announce its future projects in concrete detail, it can take plenty of time to reshape requirements as more information is uncovered and new situations encountered, before committing to a design-build-buy. For neither good nor bad, the situation in Singapore is very different from that in Australia... at least for the Hunter class I am open to cutting the DoD some slack. Singapore's defence policy and bureaucracy in general is actually efficient, but I reckon it projects efficiency considerably more than it embodies it.

Similarly, a delayed project may actually be a good thing for the public purse, as deferments may be used as a political way - as an evil necessity - to reap some savings needed elsewhere. So long as conflict doesn't actually come and key capabilities are not lost (ST Marine is dual-use doing plenty of commercial jobs... Australia's shipyards do not seem to be so they must be funded), then one could very justifiably say that it was a socially beneficial thing - beneficial at a country level.

For that matter - whither JMMS, Fokker F50 MPA replacement and C130 replacement!
