According to Babcock on their website:

“Babcock Team 31 has been contracted by the UK Ministry of Defence (MOD) to deliver five Type 31 frigates.

The contract, which was awarded in November 2019, signalled another decade of ship-build activity for the historic dockyard at Rosyth. Building on the unique experience and success of the Aircraft Carrier Alliance, Babcock has brought together a highly experienced and integrated project team spanning several regions of the UK, to meet the challenging Type 31 programme. This pathfinder programme, as described by the MOD, is the first of its kind to be delivered under the new National Shipbuilding Strategy.

Re-energising the UKs’ maritime capability through modern UK ship design and build practices, the Type 31 programme will also support technology transfer into the UK through the command system and drive British shipbuilding expertise to match the Royal Navy’s pedigree as a world leader in naval platforms.

Type 31 will be at the heart of the Royal Navy’s surface fleet, deterring aggression and maintaining the security of the UK’s interests. They will work alongside the UK’s Allies to deliver a warship presence across the globe and enable a forward naval presence.”

Arrowhead 140 – Babcock’s solution for the Type 31 programme – has the following specs.

Key Platform Characteristics

  • 138.7m LENGTH OVERALL
  • 19.8m BEAM, MAXIMUM
  • 5.0m DESIGN DRAFT
  • 6,000+te DISPLACEMENT
  • 32+MW MAIN ENGINE POWER
  • 28+Knots SPEED

For more on their distinctive gun turrets, have a look at this great article from NavyLookout.

In focus: the Bofors 40mm Mk 4 gun that will equip the Type 31 frigates

What is the status of the project?

In September Secretary of State for Defence Ben Wallace cut the first steel for the first of the Royal Navy’s five new Type 31 frigates, HMS Venturer.

Steel cut on first Type 31 Frigate HMS Venturer at Rosyth

The five ships in the class will be HMS Venturer, HMS Bulldog, HMS Campbeltown, HMS Formidable and HMS Active.

Sea Ceptor is deployed in RN ships in their own tubes not MK 41, so the number of MK 41s will not determine the number of Sea Ceptors. I have seen art that shows 24 and some that show 12… 32 would be best….

If Mk 41 VLS is fitted then the space for Sea Ceptor tubes is limited to perhaps 12. If we decide not to install Mk 41 then 48 Sea Ceptor tubes can be put in the space available. I think this is the current conundrum. Do we include an minimum fit of 12 Sea Ceptor to leave space for 24 Mk 41 VLS, or forget Mk 41 and fit 48 Sea Ceptor.

Maybe because that is the source of some budgetary debate ATM? And maybe there is a debate about using the already ordered Mk41 VLS for T26 #2 & #3 to equip the early build T31? I suspect the T31 will only get 16 VLS cells (two rows of eight) as that is about £17M worth of VLS – if the £50m for 48 VLS is correct. Mind you there is space for 32 VLS on the IH and £34m per ship isn’t going to break the bank either. Given the glacial pace of T26 there is plenty of time to… Read more »

That’s a fair point. I’m pretty much certain the ships will be delivered with a “basic specification” that is built to cost. Even though the SeaCeptor is GFE, building the infrastructure to house them will down to Babcock. So if their margins are thin, they won’t be giving away any freebies. Thankfully the Arrowhead design has plenty of room for growth. Could you imagine the discussions being had, if we went down the BAe Leander route?

Radakin seemed keen to get Mk 41 on Type 31 – he also said some decisions were being left late as Type 31 is plug and play and they can make decsions closer to in-service date to ensure latest tech and requirements are met – a different approach to that used for T-26. I suspect the number of Sea Ceptor and/or Mk 41 is still being decided.

For maximum load out for the least money, I would go for 2 sets of 8 cell mk41 (16 cells) & 4 sets of cheaper & lighter stand alone 3 cell ExLS (12 cells). That gives 48 CAAM/CAAM-ER soft launch & 16 of whatever hot launch you want. Since the A140 design can take 4 sets of mk41, this should all fit in the designated area.

The suggestion, from inside sources, at the moment is that Sea Ceptor/CAMM is not integrated with ExLS yet. At least not in quadpack format.

LockMart and MBDA were confident it would fit and released pretty graphics to everyone….but when they tried it they got an unpleasant surprise. Every CAAM/Ceptor installation currently deployed is the ‘mushroom’ version based off the GWS26 VLS cannister.

I thought they completed qualifying it in 3 cell ExLS at the end of 2017? Is it the 3 cell stand alone that has a problem or the drop into mk41 version or both? Canada has specified stand alone ExLS for CAMM on their T26.

I gather the single cell MBDA tubes are the cheapest way to go per missile. But they take up a lot of real estate. You end up ripping gear out later to fit new, rather than simply adding. If you said no mk41 & fitted 36 CAMM, well ok.

The possibility of having one drone in addition to a manned helicopter, must greatly enhance air cover? What if there is enough space to store a couple of smaller drones, that would be a major step forward in the ship’s lethality?

How do you know? …have you heard its underwater signature?

Iver Huitfeldt is optimized for an ASW speed of 12-18kts in a special ASW propulsion mode where they have to lowest noise profile. T31 is a little bit lighter than IH and has a newer generation 5-bladed CP propeller which is a little bit less efficient but quieter than IHs 4 bladed design. This means it should be able to sustain higher “silent” speed for ASW…perhaps 20kts or more.

Badly expressed.

Most ships are too noisy at any decent speed.

T23/26 are exceptionally quiet.

However, sprint drift was the pre T23 way of getting round this.

I agree IH is a decent ASW platform. But it is not at T23/26 level.

The engines in T31 are also in full acoustic shrouds and isolated. Trouble is all the other pumps and motors that make a ship tick.

FYI the faster a ship goes the more noise it produces period. The more noise it produces the less effective it’s sonar’s are, whilst increasing its .
counter detection range by SMs.
ASW is a slow game, always has been, charging round at speed utilising passive/active systems puts you at a massive disadvantage. That’s why T23 adopt EM drive when hunting, at 18 it’s your operators are effectively blind!

Why is it too noisy? – the Danes happily use theirs for ASW. There is simply no evidence for these assertions, it’s just an internet meme about Type 31 made up in forums, like the one about F-35 being useless. You can’t do ASW at speed with hull sonar full stop – even Type 23s need to go slow on electric drive.

Hopefully T-31 and T-32 will be reconfigurable for all these roles using modular offboard PODs.

Perseus is only planned to be available in the Royal Navy on Type 26s and there won’t be any operational Type 26s until 2027. The most operational ships that could have it by 2030 is three. However, like you, I think 2028 as announced by Quin during the concept phase is highly unlikely. He only said it was a planning assumption.

Possibly, don’t forget the missile gets a large helping hand from the launch aircraft’s kinetic speed as well. From a ship or land based system, the missile is launched from a standing start. For example, the AMRAAM when used as a land based SAM, its range is about 1/3 of that when launched from an aircraft.

I suspect CAMM could well have a maximum range of around 60km when used ballistically. Probably a lot less when maneuvering to an intercept point.

I still think there’s value to the FREMMs and the lack of AShMs on the Type 45s is less severe than it seems; as installing AShMs or attaching Mk.41 VLS to it would take a far shorter amount of time than building a ship from scratch.

If you take the decision of the french navy to set the FDI with 16 VLS, with the best radar in the navy and a 450 to 800M€ ship.

Depends on the navy, largely because different navies used different words in WW2. During WW2 what had been the Torpedo Boat Destroyer aka Destroyer basically broke into two roles; Anti-Submarine and Ant-Surface/Torpedo Attack. The Anti-Submarine branch (favouring slow speed, but good manuverability) in UK service where called Corvettes, Sloops and Frigates, Frigates was the term that stuck. So in the RN the term “Frigate” applies in general to a ship optimized for Anti-Submarine Warfare (even though what that means has changed since 1945). In the US Navy that term was Destroyer-Escort (hull classification DE). It changed a few times in… Read more »

It is a damned sight quicker to put missiles in a silo that exists than it is to add the silo and then put the missile in.

There are already shared stockpiles for the P8. So there is a model to follow.

Personally I would rather see the Mk41 VLS installed.

Understand the sentiment but I reckon it’s more about being able to declare the procurement program a success than the capability of the ship now.
Type 31 will be a ‘patrol frigate’ and any offensive capabilities will be for the Wildcat and its missiles.
Having accepted the principle of a mixed fleet, which with global River 2s and T31 we surely have, it becomes a question of first rate intelligence and how quickly can you support the ‘man with the ball’. Where’ the nearest Astute/ Typhoon/ F-35/ P-8 with Harpoon?

It’s sort of irrelevant to be honest as different navies use different names. From an RN point of view destroyers focus on air defence and frigates focus on ASW work.but not always as the T82 destroyer had a significant ASW role as well as air defence and the type 31 frigate is going to be mainly focused on surface action. In truth almost all modern frigates and destroyers do a bit of everything. Often ships are named for political reasons, does a navy want to be seen to limiting its expenditure, then it builds frigates the size of cruisers, if… Read more »

Mk41 is very expensive and has a long lead time. The only ones on order are for Batch 1 T26 (9 off I guess). All that can be said about T31 is there is space reserved.

How fast do you want to go?? Likely an increase in top speed to 32 knots would need an installed power increase of at least 50%, with the fuel consumption and so on that would entail.
Again the spectre of not being able to provide NGS for all those opposed landings we are going to make rears its ugly head. Yes, its going to be tough putting troops ashore without knocking out all those fixed defences, gun batteries and echelons of tanks with one frigate.

Sorry David. A bit of ironic humour on my part. I cannot see when we would ever be likely to make landings such as to need NGS, but it irks me that whenever the T31 is mentioned with its small guns, the lack of NGS crops up.

I am thinking that if the Russkies invade the Ukraine we will not be sending any part of our small army over there to help, much less re-invade.

Increasing the speed of a ship is not as simple as just putting in a bigger engine. Length-beam ratio limits the theoritical speed, drag and friction is another factor. Sometimes just to get an extra 2 knots 35-50% more power is needed. So we have come to the point that 25-32knots is a good length to beam ratio and good power to length ratio.

Having read that in the last 70 years only a handful of anti ship missles and large calibre naval guns have been used peer to peer fighting why would we waste money on something that won’t get used? In the last 70 years nearly all peer to peer ship fighting and shore battering has been via CSG. So the only anti ship strike weapons we should be prioritizing is something the F35 can fire. All the Type 31s will be doing is merchant ship escorts through the gulf and drugs and pirate tasks along with ceremonial duties. And it’s armament… Read more »

They definatley need one of the cheap off the shelf ASM systems.The Russian Provorny (Agile) corvette which caught fire yesterday in St Petersburg at the Severnaya Verf shipyard is now apparently a total loss. This ship was to be fitted with hypersonic missiles. These things are a game-changer, they come in so fast. The Russian corvettes need to be engaged from outside their missile range, our frigates and destroyers should be able to defend themselves first with anti-ship missiles

The Harpoon is now obsolete and despite the Authority spending precious money on maintenance, it will be withdrawn shortly.

Built by Lockheed Martin, JASSM-ER is jam-resistant and stealthy, with a range of 500 miles. JASSM-ER is designed to autonomously detect and attack targets based on an uploaded profile and can deliver a 1000kg warhead. The ASM of choice.

It’s the blinkered way of thinking the navy has chosen to go. The wildcats are fitted with sea venom so technically the t31 if in contested waters will have the ability to defend itself for a limited point of view. We’ve been on the brink of war for 40 years and the navy hasn’t used the harpoons that are fitted. The t31 is a cheap boat for the less dangerous commitments that don’t require expensive weapon load outs like humanitarian missions and drug seizures and merchant ship escorts.

Sad, but probably true. The one ray of hope for the T31 is that today’s anti ship missiles like the NSM can also be used against land based targets. Land based targets will probably be the main use for such a weapon. But looking around the World today, I would say the ship needs a least something like a cannister launched NSM sooner rather than later. I would agree with the F35. It also needs a stand-off weapon with a bigger punch than the Spear 3. But as you say money is tight. If and when it kicks off in… Read more »

‘Escorting ships through the Gulf’ is made to sound like a simplistic task…..but the Iranians have the capacity to destroy a poorly armed Type 31 with ease…..indeed Iranian capabilities are heavily underestimated on here? Any escort requires effective AAW, fast firing guns for Swarms and an offensive ship to ship and land attack missiles to destroy the larger Iranian missile boats and shore based Anti-ship missile launchers. Type 23 could do with a faster firing gun/s, but does have the 4.5 inch with Sea Ceptor and Harpoon.

The argument that they need to be fired in order to be useful also misses the point of deterrence. If it’s known you can respond, people are less likely to mess with you in the first place, so you don’t need to fire. On the other hand if it’s known you can’t respond….

If they want to bolster the fleet then order 1-2, it won’t break the budget.

Fingers crossed they come in on budget, I like the 40/57 gun combo, any idea if they have the deck penetrating magazines ? Would seem a waste to buy decent guns but then have to get some poor bugger to run and re-arm mid engagement !
Also, can we at least fit some mk41’s fitted ? Anyone know the cost ?
FFBNW is just a disaster waiting to happen, if VLS is in place the ships would surely be much easier to up arm when needed ?

It appears that the Fwd 40mm gun (B position) is v likely to have a deck penetrating mount, but it’s a bit unclear on the After gun. There is a good article in Navy Lookout on the 40mm gun system being used on T31.

Last I read/saw is it costs about £10 million for a 4 cell Mk41 launcher – possibly 8 cell can’t remember exactly, but they are expensive.

BAe state that ORKA is a multi-use weapon that can be used for both surface and air targets. The imaging infrared seeker can “look” for the target or it can be guided on to the target by following a laser’s reflection. BAe have tested it against boats swarms, but yet to test it against anything faster than a small aerial target drone. In theory it should be able to track anything the sensor sees or is guided on to.
