Rolls-Royce is to supply complete MTU propulsion systems for five new Type 31 general-purpose frigates for the Royal Navy.
In total, the order comprises of 40 engines and generator sets to be used for main propulsion and on-board power generation, the MTU Callosum propulsion control and monitoring system, and Integrated Logistics Support (ILS).
“Each new frigate will be powered by four MTU 20V 8000 M71 engines, each delivering over 8,000 kW. On-board power will be provided on each vessel by four MTU generator sets based on 16V 2000 M41B units, each delivering in excess of 900 kW. The Royal Navy relies on Rolls-Royce propulsion solutions across its surface and submarine fleets. MTU Series 2000, 4000 and 8000 units will feature in future in most Royal Navy warships – in destroyers (Type 45), all frigate classes (Type 23, 26, 31) and submarines (Astute class)”, say the firm in a statement.
“We’re delighted to welcome Rolls-Royce with its MTU solutions as a supplier to our Type 31 Programme. Its engines and on-board generator sets are already proving their mettle in numerous comparable vessels worldwide.”
Knut Müller, Vice President Marine & Defense at Rolls-Royce business unit Power Systems, said:
“We’re very proud of the fact that Babcock International Group has opted for MTU propulsion and on-board power solutions on this highly significant project. MTU products now feature in almost all current and future projects of the Royal Navy. That is impressive proof of the trust our British partners place in us and of the reliability and flexibility of our products.”
In September 2021, Rolls-Royce will deliver the first shipset comprising four main propulsion engines and four generator sets to prime contractor Babcock International Group. Integrated Logistics Support for propulsion and onboard power systems will ensure efficient and cost-effective maintenance throughout their entire service life.
It is expected that the MTU Callosum propulsion control and monitoring system will be officially added to the supply contract very shortly.

Nice to see progress on this programme.
Cheers CR
Still only 5 hulls though…
The 31s will be able to manage 29 knots at full tilt which is not bad at all.
Yeh, as platforms their basic capabilities are pretty good and could form the basis for a very effective ‘force miltiplier’, but they are going to need more ‘kit’ if they are to be able to take their place in a war fighting scenario.
I agree, as ‘currently’ configured I don’t see them suited to any war fighting. Even non peer potential enemies have small vessels that are more potent.
Saddam’s navy was destroyed by Lynx helicopters, nothing different here. All the Army’ Wildcats are navalised.
It’s slightly embarrassing how the ships it’s replacing will be more powerful! They should Atleast get the 23s mushroom farms when they come off even build them fitted for the 32 cell untill we have the almost new sea ceptor system of enough 23s or even just fit a new 32 cell It surely can’t be that more expensive than fitting a 12 cell.
That’s funny. When the Danish CO of Iver Huidfeldt was interviewed, he said the ship could do 18knts on a single engine and over 30 at full tilt.
40 sets, 4 sets per ship, 5 ships… Have they ordered double the required amount for spares, for other ship types (26 & 23) or am I missing something? Either way, good news!
Yeah that confused me for a bit but if you read it again it’s 4 x M71’s for propulsion and 4 x M41B’s for power generation. 8 sets per hull.
Yeah that confused me for a bit but if you read it again it’s 4 x M71’s for propulsion and 4 x M41B’s for power generation. 8 sets per hull.
Ah, that makes sense. Thanks for the clarification.
Only 12 Sea Ceptor missiles!! – I realise this could change come entry into service but if it stays like it is, I wouldn’t want to be one of the poor sods sailing in one come a full blown shooting war! She’d last all of 5 mins! Ok, purely speculating but you know what I mean.
Why they just don’t put even 12 Syler or MK41 silos that can be quad packed on them is beyond me… False saving, obviously.
Finland spent $70m on procuring 4 Mk 41 launcher systems.
So you will need to add more then that, to cost of T31, before you include the missiles.
How they can justify £70 million is beyond me. I looked up Sylver thenither day and I found a figure of £3 million per bank of 8. Dont know if that’s correct but seems much more like it for what it is. Surely we could design our own for a fraction of the cost so money comes back into our economy and we can afford to give a decent number to each of our escorts?
Whe it comes to FMS prices levied by the US Government, just think of it, a portion is like a tax.
The US pays around $50mm per DDG for 96 MK41 cells. So that’s a little over $4mm for 8 cells. Looks like Finland got robbed but when they did not invest billions in R&D maybe its only fair.
If the UK was quoted the same price though I can see why its opted for much cheaper soft launch silos although 24 should be minum in my opinion.
No point in using an expensive VLS designed to handle hot launch in order to quad pack cold launch CAMM. Which is probably one reason why T26 has dedicated cells for CAMM, instead of 12 quad packed Mk 41. Sure you could use the MK 41 for something else, but the UK probably won’t have any missile qualified for MK 41 for approaching another decade. When it does it may well be Aster 30 variants first.
Why can’t we just cross deck the existing 32 cells from retiring Type 23s?
Several reasons come to mind but others more knowledgeable could probably confirm the following.
Sea Wolf was hot launch so whatever remains of the VLS in a Type 23 is larger and more complicated than is needed for CAMM, you can see that with the spacing of the cells as well, it probably just wasn’t worth the cost of ripping it out to fit CAMM more efficiently in Type 23. However, no reason to waste space in the mission module space for Type 31, or deck space in the event you want to add other deck launched options.
Then there’s the rationale for whether the T31 actually needs 32 CAM, or anything close to that number for its likely roles. We’ll have a high-low frigate fleet with the Type 26 vastly more capable than Type 23 ASW/GP variants (24x Strike length MK 41 plus 48 CAMM in two separate banks) while T31 has fewer SAM but much more flexibility for other mission module based roles.
The old hot launch capable tubes for VL SeaWolf where adapted to take the much more compact Sea Ceptor cold launch canister. There is no point cross decking old SeaWolf canisters.It would be a waste of time and money. Its far easier to build a dedicated silo to take the SeaCeptor canisters.
Does a T31 need more AAW missiles? That depends on the mission. If its going to take the role of Patrolling and low intensity work no it doesnt need any more. If its going to be used in high intensity areas then lots of bolt on additions can be made.
GW1 the UK MCMV force got additional EW, Chaff Launchers and 20mm guns in the space of 2 weeks. It all came from war stock stores held by MOD. If its needed you would be surprised at what can be done at short notice.
Because they need them for the Type 26 which has 48 cells,the system needs 3 launch control and 3 flight controller cabinets per 12 cells,its not just about the missile launchers.
Hi GWM – thank you for the explanation – I really appreciate it when someone who has more insight and knowledge than me shares it – that way we all learn and become a little more educated, especially when it comes to the Royal Navy.
No problem but I do agree with others ,12 cells is not enough on these cost constrained ships, it’s a disgrace sending our service people out in ships with insufficient defences.
I can’t see why they don’t just reduce T26 to 40 and T31 could have 24. T26 won’t miss 8 as much as T31 will miss the 12
I dont think reducing the number on a 26 is good we need them to protect the carrier’s, a sea cepter block consists of 6 launch and control electronic cabinets and 12 cell launcher so reducing the 26 means 36 cells.The total available blocks on the 23’s is 39, so with 4×8 required for 26 it only leaves 7 blocks for the 31 hence only 1 fitted.The MOD needs to spend some more money and buy 3 more blocks to give the 31 24 available cells.
Or they could fit 24 to 2 x T31 & leave the others at 12. Or build an extra 2 x T31. Going to 24 on two of them would give some options if areas start to heat up, short of replacing a T31 with a T26 or T45 (which can sometimes be seen as provocation).
Yes but personally I hope they fit them to the carriers to beef up their inner layer defence.There is another option for 31, the U.S. is developing madfires guided shells for the 57mm gun, this is capable of shooting down hostile air targets including missiles so could boost their defences.
I would agree, but the issue is the density of cells with the seaceptor cold launch tubes. Fitting 24 would likely take up all the space and mean no hot launch cells could be added easily. We need a quad pack cold launch cell so 12 could be fitted allowing 48 seaceptor, and still retains space for 24 sylver/mk41 if we ever do get to up gun them.
The Land Scepter/Sky Sabre shows how closely CAMM can be packed using the standard canister, so fitting 24 if required wouldn’t take up much space. That said Lockheed has developed the simpler 3-cell ExVLS for Sea Ceptor that uses quad packing and can launch 3 missiles simultaneously if required. Also there is a lot of space on T31. Recall that the Iver Huitfeldt has space for 32x MK41 cells + 24 ESSM in Mk56 cells + 16x Harpoon in that deck space.
CAMM lends itself well for deck mount to optionally increase loadout were it deemed necessary/desirable. So 12 cells isn’t really a limit.
Am I the only one who thinks it’s concerning that we seem to be entirely reliant on MTU (yes it’s owned by Rolls Royce but the entire system is made in Germany) for our diesel gen-sets? Do Cummins Marine (formerly Perkins) or MAN at Colchester (ex-Paxman) not make suitable models? I understand the argument for commonality but surely having a local supply chain and manufacturing capability is also of merit.
It’s a shame what’s happend to british industry and the blatant lack of control over takeovers ect further losing british brands and manufacturing! Look at our truck and tractor manufacturing! But hey we bought over 7,000 millitary trucks for our army from Germany.
Your right, I didn’t realize Rolls Royce was now a German company. I’m assuming this part is nothing to do with the aircraft engines?
Alan
You have it backwards. The UK company RR Holdings owns (bought) the German company MTU (actually they bought the company that owned MTU, amongst other things). This is the same RR Holdings that own the companies building aircraft engines in various places around the world that you were referring to. It does mean however, that the engines concerned will be designed & built in Germany & exported to UK.
There are no UK makers anymore. It’s either MAN, MTU or Wartsila.
All the old UK companies have been bought out and absorbed into bigger companies such as MAN.
Exactly my point mate, it sucks, we did have loads. God knows why we allow it! The government say it’s just capitalism and shit happend! We should have been protecting our brands and growing them like Germany does….But at,east we beat Germany in the financial sector by a huge mile, hell London even beats New York.
You’ve said it. You’ve provided the answer to the question. Our best brains go into financial, legal and accounting services which are among the best in the world and earn us most of our foreign exchange and account for almost a third of out GDP. In Germany, France, Italy and other countries their best brains become engineers. It’s cultural.
Yeah maybe so, Atleast we still have the goal of 25% of the British economy in the manufacturing sector
One can only hope. But it takes concerted government action.
Neoliberalism at it best….the industry we have is dictated by the market place. It’s just a shame the rest of the world was so misguided and played mercantile/protectionist games with their industries…still we got some cheap stuff even if all the tax revenue and jobs went to another sovereign state.
As far as I can tell the old Paxman works at Colchester still manufacture marine diesels under MAN, and Cummings make or at least package some diesels down in Dorset although those look smaller. But these options may not be appropriate for RN use, I don’t claim to be an expert.
I don’t think we should call these frigates, they are probably the most underarmed modern frigate on earth they are large patrol vessels, actually the batch 2 OPV would be great with the kit that’s going on the 31s, 12 sea ceptor would be great and multiple guns ideal and a hangar with say a well armed wildcat would be even better, one can dream but the opvs are bigger than some of our old frigates. Its actually embarrassing and when I hear people say “Britain rules the waves” because we have two huge carriers and are building 13 new frigates it just makes me cringe!, we haven’t even got the basics like enough well armed frigates and destroyers. I can name countless poorer world navies with better kitted out frigates, ok they might not have 13 of them but not far off.
And so We end up with only 14 (not 19 as promised) true war fighting/ escort vessels a further reduction in numbers…what a surprise, I hope I’m so wrong and they do arm the 31s properly or just increase the dam budget we are the 6th biggest economy on earth with London the world financial capital!
Agree 100%. Give them at least a bank of sea spear or spear, III to deal mith multiple small craft at range,… Corvette or frigate at range or land attack in support of special forces.Low cost British punch.
Adding lazers wgen ready would also help
Since I already typed this out on STRN I’ll just re-post here –
Some thoughts on the ever lively discussion regrading equipment fit.
I’d suggest the way to think about T31 is as a relatively blank canvas to which options may be added/removed to increase/decrease capabilities based on mission requirements/deployment risks. These solutions can all be added over time as budgets/needs/solutions develop and thus avoid large up front capital expense.
For example,
1. If more CAMM are desirable then deck mount additional launchers. The rest of the necessary infrastructure is already there. Cold launch makes it even more straightforward.
2. If ship launched ASM/land attack are required then deck launch canister options for NSM (if this is the interim solution), Brimstone Sea Spear, Sea Venom or SPEAR 3 if any of the last three ever materialize in a ship launched role.
3. If ASW is your game, then mission module based solutions operating from USV are one option that side steps need for a super quiet ship. Or deck based ISO containers for CAPTAS. Or bolt on something like the Krait Defense System from SEA (which took 2 days to do in an exercise last year). We’re not going to suddenly get Type 26 capability doing any of these but it may be fine for home waters, littoral work. Embark Merlin, Wildcat and/or UAVs for sonar buoy and torpedo deployment. ROK navy already has Wildcats with Flash sonar and torpedoes.
4. MCM, again by using USV/UUV mission module solutions
Many of these could be fitted to the ship at the same time to provide multiple capabilities. They could be flown anywhere in the world to upfit a deployed T31 if a situation develops. When not in use they could be warehoused and serviced on shore, ready for immediate use. None require Mk 41/Sylver VLS. A number of these solutions might even operate off a River B2. Given the nature of a number of these options, e.g. MCM and ASW, a specialised team would probably deploy with the system and not be part of the standard crew.
Edit: Forgot to add deploying UUVs for ASW. Also that a MCM mission module might be beneficial for T26 too. You might even use CAMM deck mount on T45 so that Sylver is used for Aster 30 conventional and BMD variants.
Morning Cam
I think you should actually look at other navies and how they are perceived and equipped,compared to the RN, before being embarrassed.
No way am I embarrassed by the RN.
Britain rules the waves? Different era. No one should be saying that now, which is fine, as history has moved on.
These other navies that you can name with better frigates. What other assets do they have? What age are their vessels? What training do their people have? What experience in ASW / NATO / ICT operations? What logistic tail do they have? Are their vessels sitting in port looking pretty or being used? Are they blue water navies or coastal? What ECM ESSM do they have? What Sigint? What support vessels? Can they deploy worldwide? What SSN? What port facilities?
There is more to a navy than well armed frigates.
I myself rank carriers/naval aviation, submarines, the RFA and amphibious ships/ RM as more important than all our escorts myself.
And having said all that, yes the RN needs more escorts.
I myself support T31 as the only realistic way to augment our quality with some more quantity.
Hi Daniele hope your well, I’m in no way embarrassed with the Royal Navy just the budget “frigate” and our lack of numbers of capable vessels.
I’m proud of the RN in fact and can’t wait untill we sail a carrier battle group again next year it’s a rare capability in the world and we all should be very very proud, and your right we do have a range of logistic vessels and an amphibious capability that give us lots of options that most nations Could only dream of, but we should have a better load out for the type 31 so they can protect those vessels well if needed. Spending extra to uparm these 5 wouldn’t break the bank m8, and then have a second batch Of 5 lightly armed type 31s with the current load out.
Lets hope we do build more than 5 31s to give the RN more depth and reach, wasn’t it a promise if we didn’t build 13 type 26 frigates?. You must agree they are under armed though and 8 well armed frigates (T26) isn’t enough. We could afford 20 well armed frigates if we wanted to but the government will isn’t there. And we could recruit more if we actually wanted too. Paying off 5,000+ RN personnel didn’t help, and they sure aren’t recruiting 5,000 more, numbers of personnel is an entirely self made money saving austerity problem just like the budget black hole made to justify cuts.
But Hey we are lucky we have what we do, and I’m slightly optimistic. I was looking at the Canadian armed forces and their purchase of worn out Ozzie f18s! We are very lucky in comparison, they don’t even have enough pilots for their current 40 year old F18 fleet of 70 total aircraft.
Excellent points regarding broader naval capabilities. BTW food for thought that another way to look at T31 is as the light frigate the USN Freedom and Independence class Littoral Combat Ships should have been.
Also want to add, Daniele, that our training is ranked among the best in the world. Foreign navies regularly sent their vessels to attend FOST off Devonport. That says a lot about how the RN is regarded.
You hit the nail on the head with your post. Very few countries can match us in the ability to deploy and support vessels at sea. We saw only last year how quickly vessels could be redeployed to support operations in the Gulf, and how they were supported by additional RFA assets. It’s not just that – you may need to fly out crew, or spares. We have the assets to do so. Many navies may have frigates or even OPVs armed to the teeth, but the real questions to ask are how long do they spend at sea, how far do they deploy, and can they be supported? I can say one thing, when you look at the support fleets of most of those navies, they’re severely lacking to say the least.
I’m not going to deny we need more ships. I’m not going to deny we need to expand the size of the RFA. I’m not going to deny that we need a recruitment -and retention- drive. I’d argue for more investment in drones, and more helicopters. But it’s not as simple as a simple comparison between navies. The RN excels in many aspects and many of its contemporaries envy -and respect- it. I’m all for up-arming vessels, but right now I think we need to focus on getting hulls in the water, before we focus on refining their spec.
Agree. Which is why I’m all for T31, and even the RB2s.
FOST has a world wide reputation. I’d read elsewhere recently there were rumours of Fleet HQ considering making cuts to it!. Surely not.
I know there’s a lot of shimmying coming with regard to commands.
A bit of rebranding too – return of the use of ‘Coastal Forces Squadron’ by the sounds of it.
Oh, that’s news to me. Thanks. Will have a peep.
No probs. There’s a lot going on behind the scenes gradually. There have been some changes to FOST, (command now falls under COM FOST) and there’s a push to slim Headquarters down.
I’m going to assume Coastal Forces Command is a rebranded and reworked 1PBS.
Some ramblings that might be of interest… I’m not sure if it was published here (my COVID work has certainly made me miss several pieces!) but there was some good news for the Navy: HMS Audacious was officially commissioned. Also, the newer OPVs working up well (Tamar conducting deck landings, Medway welcomed a Merlin!) and there are some rumblings that Trent might be forward-based at Gibraltar.
Concur with 1 PBS. And I assume the FPS ( if its still called that ) will also be a part. If Mr Reeves is still around he will be excited.
Don’t think there was an article on Audacious, though we certainly knew she had finally left. We saw Medway and the Merlin here.
Trent at Gib? Welcome if true. As long as the Batch 1s remain for home waters only. There was an interesting piece on STRN some time back how the B2s could be enhanced and become useful presence vessels.
Yes, I’m sure Mr Reeves will be excited!
We have cut Sandhurst places so why not FOST, well except the paying foreigners places obviously which is fine.
Other nations send entire warships mate, not individuals. Thursday war?
Yeah it shows how highly our millitarys regraded, no one doubts that, that’s why kings and princes come to the UK to train, we also train officers from all over the globe, our army, navy and the RAF all train foreign officers ect.
Well said Daniele!
12 does seem like an odd number. Considering that they can’t be reloaded at sea, it means that the ship can defend itself against a wave of 4 jets each carrying 2 anti ship missiles, which isn’t a whole lot. Ok these will be way more effective in combat than the rivers, but I suspect they will have to operate in pairs to have enough fire power to actually defend themselves. I guess they could he used to escort supply ships operating generally outside attack range.
Do we know CAMM can’t be reloaded at sea? Sure we don’t reload Aster’s but they are much larger/heavier weapons at 3x to 4x the CAMM’s 99kg. We might also optionally deck mount additional launchers when required.
The problem with temporary deck launchers like you are suggesting is that the associated electronics also need to go somewhere. That was one of the benefits of stanflex, you had room to package the electronics into the below deck part of the module. Change the module, electronics go/come with you. Otherwise you unusually end up permanently fitting the electronics (which is costly if you intend to rarely fit the launcher but fine if you often do). I would suggest you would need to containerise it to make it really work (ie above deck ‘stanflex’ to some degree). As containers have the ability to have their own power pack, you could even try controlling it purely via the radio datalink (ie no cabled connections).
Agree that its perhaps a little glib to imply its simple to just bolt on additional equipment. A container probably would be a preferred solution rather than say the pallet like solution of the Sky Sabre trucks and might be more appropriate for temporary use on other ships too. Cleaner to ship by air, land or sea.
Constantly amazed by the depth of knowledge on subject by those who post on this site. UKDJ is definitely the go-to source for real information on subjects military! As one whose interest is generalist and historical I must admit that you guys lose me with much of the tech speak! Cheers from Durban
PS Good Morning Daniele. We haven’t heard from you for a while. Hope you are well! Did I tell you about the time me and my mate paddled up to HMS Echo in Durban harbour… :)?
geoff. Good morning! It has been sunny here for weeks and now we want some proper rain please! The wildlife need it. It is actually trying to rain now..albeit spitting only.
Lol. I know that story well, thank you. But it might be worth another airing for newer members of the forum!?
Hi Daniele-I think it has been aired enough compliments of my 71 year old brain!! Best time of the year here in Winter Durban to visit. Daytime temps in the mid 20’s with low teens in the evening and no rain! Our summers are generally lousy and unpredictable-either rain for days on end or humid and hot!
And always happy to hear it again geoff. We should learn from our “experiences” of our elders!
Given the complexities and poor record for UK defence procurement and the requirement to kick start the economy after COVID. Why not have a 10 year shipbuilding strategy that is based on additional funding that looks to the sustainable development of shipbuilding and related industries? Surely a plan that included 7 new build T26 (bringing the total up to 10) , 6 T31 (at a higher spec) 3 Mars sss, plus a 2 for 1 areplacement fior Argus (for disaster reluef) must be doable for around 15 billion spread over a 10 year period ?????
It would also give the main defence budget some head room and actually give industry the chance to plan long term invest and be more efficient and for a better budgeted outcome
simple answer is there are better ways to generate jobs and boost the economy than ship building, for example improving the infrastructure (roads/rail) that will generate jobs during the improvements and also after.
Yes in part, but long term industrial strategy creates both skill base and resilience. Peoples working habits are changing, therefore the likes of HS2 may be a white elephant .
Whilst I suspect the HS2 impact will be lower, people will still need to get around and it will still generate income / economic growth. Who knows if that income will justify the cost post Covid, we are all hoping that life will eventually return to normality, but that is currently just a hope.
The problem is ship building is not profitable and using state aid to prop up an unprofitable business is not good for the economy, its done purely to win votes, but ultimately its lost money as the second you stop the state aid (which with a shrinking navy is highly likely, look at the money having to be thrown at BAe via the River2 to keep the operation open) the industry fails and the money is gone. If they put that aid into industries that have a chance to stand on their own feet without the aid, then the long term gain will be worth it.
There are potential to do this in industries that support the military, such as the space project or tech firms (assuming we do something to protect our domestic firms better against US anti-competitive practices) and a whole load of more traditional firms that support the military.
Its whether we think a shrinking navy is 1) A good thing 2) whether we want a manufacturing base 3) whether we actually want procurement to be more efficient 4) Whether we want to avoid the BAE Barrow saga where because of the on of nature of submarine procurement BAE lost a lot t of its skill base and needed a lot of expensive help from the electric boat company. Because the lack of long term planning and a proper strategy costs more money in the end.
There is no more capacity to build 2 more T26s on the Clyde,
They would have wait until 2040 to get built.
The core issue with ship numbers is the available budget: from memory, we have £1.7 bn pa, which likely includes weapons and fuel and refits and whatever else. With a T26 and T45 costing £1bn each and 59 ships in rhe surface fleet, there is simply no money over to increase hull numbers or even to equip ships properly e.g. T31.
It is revealing that the surface ships budget over 10 years is £17 bn, the submaine budget – for 11 boats! – is £45 bn. That ridiculous figure shows how much of the nuclear budget was slipped from the Treasury to the MOD by the Conservative government.
The only answer I can see to righting defence procurement budgets is either (a) put the nuclear tricks budget back in the Treasury, as the independent deterrent is a national political symbol rather than an essential military requirement that the staffs are agitating for, or increase defence expenditure to 2.5% of GDParis by 2030. You could do that incrementally over 10 years, reaching 2.25% by 2026, which would be a more attractive route for a reluctant Treasury/Government.
Even that size of increase would, given the high inflation rate in defence procurement and the massive hole in the MOD’s budget, allow about a 12.5% increase in trained personnel and a 10% increase in surface ships i.e. 6 ships. No one need argue the difficulties of achieving either option, they speak for themselves.
On BAE , surely capacity can be expanded, on nuclear deterrent, well yes it cripples the whole defence budget. I would rather we didn’t have it. But if we do then outside of defence budget as it used to be. But that is why I am proposing a shipbuilding strategy paid for in addition to the defence budget. Its a cheaper and more politically acceptable way of supporting the shipbuilding industry and the RN
I don’t understand the criticism of the T31, for what it is designed for (low to medium threat environments) its fine, and saves wasting T45 and T26 overkill. The question shouldn’t be why ‘isn’t the T31 better armed?’ but ‘are we building enough T26s?’.
What is glaringly obvious is this. Lower tonnage systems based warships such as Frigates and Destroyers have a higher foreign content then bigger tonnage warships such as Aircraft Carriers and RFA ships. Cammel Laird said their UK content for the type 31 ships was as high as 70% and I am sure it is lower with the chosen Type 31 and also the Type 26 ships (in which BAE dine a deal to buy mysterious flater Swedish steel). But 90% UK content is given for the two super Carriers and being bigger and more steel intensive ships as opposed to frigates and subs etc, the FSSS will have a far bigger UK content than Frigates too.
