These images show how the Type 31 ‘Inspiration Class’ Frigate will look and they’re more up to date than the imagery we’ve shown recently.
The images show the vessel in a wide range of roles.
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

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.
The five ships in the class will be HMS Venturer, HMS Bulldog, HMS Campbeltown, HMS Formidable and HMS Active.
The burning question still unanswered is how many Sea-Ceptors will it have!!!!
I think the burning question is will they get Mk 41 VLS – that will determine how many Sea Ceptors.
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….
Wikipedia says Up to 24 CAMM missile cells.
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.
They’re should be room for both unless they go 4 x MK41s.
It was the burning question to the former 1SL for sure.
Yes. It’s the first thing that hits. Lol 😁
Funny how all the latest images of the ship, don’t show a top view! Though when question by the Defence Select Committee, the Chief of Staff, did make the comment that he wanted all ships to have more offensive capabilities.
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 order more and they don’t have to be in place at launch as they can easily be fitted with an overhead Goliath crane.
I have zero info on this but that is what I would do if I was trading off the wants and needs.
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?
Babcock’s and the MoD are using this project to prove a point. Build a ship on time and to budget. Once it’s delivered I’d fully expect its load out to change. But it also puts Babcock in a very good position for the T32 order.
Totally agree with that.
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.
Agreed
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.
Not sure that they would use the ExLS Camm on the T31 and not on the T26/T45s? Could be “mushroom” Camm all the way through, terribly space inefficient but maybe they’re reloadable at sea. Does anyone here know?
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.
regardless of the number of cells, we will only stock 20 units
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? The newly updated illustrations look very impressive, now let’s make it ten hulls!
31 + 32 = 10 ?
That seems to be what the conventional wisdom is proposing…if T32 actually makes it off the white paper
Towed Sonar off the back in the 2md image ?
Yes – maybe towed array POD is planned.
That or the towed decoy part of Sea Sentor
It’s this.
Cheers for the confirmation George 🙂
Is that a towed array I see coming out the stern on Pic #2? On a GP frigate?
Expansion of ASW capability is needed. Would be good if so.
Could just be a concept image for other prospective buyers. Strange either way as we’ve been told time and time again that the design is far too noisy for effective ASW operations.
only effective way for T-31 to conduct ASW would be using Merlins at stand off distances? but would need to carry 2 or 3 to be effective.
Too noisy for hull mount sonar at speed.
Nothing to stop you putting engines to stop and listening on the towed array?
Ok it won’t be as good as a T23/26.
Personally I favour sonar towed by E-drones. Much cheaper than building quiet frigates.
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.
All true.
And why T26 electric drive is for low speed only.
If they don’t, ownship noise will drown out your own operators !
I mean one of the options for the pod system is a battery pack to allow for running on electric only for short durations.
The T31 has no electric drive at all.
Otherwise it might be a good idea….
But T32 might have?
Unlikely as it will drive costs up.
More likely are battery driven UAV’s with a towed array.
The drawback with E-drones is short legs, particularly with a heavy load to tow. The weight and drag of a TAS is nothing to a frigate.
True
But it is at least a solution.
So you might have 3-4 used in rotation?
Equally you might just use a silenced diesel for the UAV with electric drive.
Yes but not by people who are actually in a position to know.
While you dont have to be a marine engineer to figure out that the T31 is going to be noisier than T26, the notion that it is SO noisy that it cant be effectively used for any kind ASW, is frankly rubbish!
Yes, in traditional open water ASW operations with use of primarily passive sonar , the CODAD powered T31 is at a disadvantage However modern submarines are so quiet that passive only sensors are no longer considered a viable means of detection, giving way to multistatic active sonar. This means that having a slightly higher underwater signature is not the issue it once was.
Also a T31 (equipped with decent HMS) would be perfectly suitable for active ASW operations in confined, relatively shallow waters with high ambient noise levels , like the baltic, mediterranean and black sea.
No-one has said that offically. I think it’s an internet assumption made true by repetition. The Danes use the both the Absolom’s and Iver Huitfields for ASW..
are they actively awful for asw like the type 45 or just not particularly good at it do you know? I worry at th fact that it seems our asw capability is mostly tied to 8 type 26’s which also have the burdon of higher end general frigate duties too.
On the plus side, type 31 does seem like a winner in terms of ship building and exports
Just need to add the ASW torpedo tubes from the export version.
If you are in range of ship mounted TTs, you are too close to your target. You need to kill a sub before it gets into attack range with a helicopter or a ranged ASW weapons. So ship TTs must be seen as a last resort….
A helo cannot be airborne 24/7. If a sub is a hole in the ocean & waits for our taskforce, then pops up, I want some way to kill it quickly, not faff about with getting the helicopter out of the hangar & armed.
Which is why in a threat environment helos are not kept at alert 45 in the hangar. they are ranged on deck. You fully spread them and arm them up ready to launch at alert 15 or alert 5.
You can pull them forward so that they rest close to or slightly in tha hangar for some additional protection.
Hi John, yes, even as a backup to a helo. Not sure if the RN is looking at any ASROC type system for the T26/31/32s but there was an image recently of a UAV with a torpedo.
That is why the ASW platforms can use active sonar…. dipping sonar etc…
That or the towed decoy part of Sea Sentor
Nope, George said above. It’s the towed decoy.
It could also be a power/data cable for a unmanned underwater vehicle.
Images look like 3 different confirgurations (maybe using PODS?). Sea control with interceptor RHIBs, AS FIND UAS and Wildcat with Martlet (e.g. Gulf, Anti-piracy etc.), ASW with Merlin and towed array, and Carrier Strike surface combat escort with AShMs and Wildcat. Hopefully T-31 and T-32 will be reconfigurable for all these roles using modular offboard PODs.
I’m sure I can see a quad anti ship missile launcher poking out midship in the image with the Queen Elizabeth in the background.
Yip – saw that too Jonathan – here’s hoping!
Hi Jonathan,
I suspect that imagine was produced prior to the recent announcement that the interim SSM has been cancelled. The RN will not have a SSM until the new Anglo French FC/ASW missile which is supposed to be ready in the 2028/30 timeframe (although I think 2035 is more realistic, hope I’m wrong).
Cheers CR
If I was a betting man I would put money on you being right, But I think of all the platforms, these as general purpose frigates with a guns focused on surface warfare would be the best platforms for an Antiship missile. Although if I was choosing I would pick more seaceptors first, then armed drones, then ASW fit/drone, then anti ship missiles ( but all Four would be best).
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.
And if the system actually becomes available in the early 2030s, which is more realistic, we’ve seen how many years it takes to equip frigates with anything new. I’d hope with the Mk 41 VLS it will be faster for the Type 26s to get Perseus than for the Type 45s to get CAMM, but I won’t hold my breath.
As I understand it, until recently all Type 23s and half the Type 45s had Harpoon launchers. As even by 2040 only three of the eight Type 26s are likely to be deployed at any one time outside of surge, there seem to be no plans to make anti-ship missiles that generally available ever again.
Cancelling the “interim” missiles which could have been launched from cheap deck-mounted launchers and rotated between highly available Type 31s was a great pity. We could have had 30 years use from them.
I think there was a political dimension to the decision to cancel the interim AShM. It was important to send a signal to France that we are fully committed to Future AShM.
I noticed that earlier this year Boris announced we would have a National Flagship and that it would be in the water by 2025.
It’s to be paid for from the Royal Navy budget but it’s totally unfunded at the moment. It’s going to cost £250m. I wonder where the Navy could get the money?
Thank heavens they would never cancel a funded weapon system to pay for a useless vanity project. The political dimension to the cancelling of a £250m missile programme was obviously a signal to the French, and the fact that £250m has miraculously become available for another project is entirely coincidental.
Thank you for elucidating that Sir Humphrey.
It is as you say a complete coincidence……
If you believe that I have a bridge to sell you?
Interesting that the FC/ASW is going to fit into a Mk41VLS and not just the French DCN silos. I’d like to see the newer Aster 30NG fit into both versions too but don’t think it does or will.
Type 83 will force that issue I think.
God knows how much time and money they wasted on assessing the Interim AShMs to date if nothing has come of it. Hopefully a good decision.
Down here in Aus I read somewhere about the RAN exploring putting canister AShMs onto their new 80m Arafura patrol boats. Even smaller than the River B2s plus with a 40mm.
Hi CR. It is a bit bewildering that the interim missile has been cancelled or has it? The reason for this is the CAS’s statement during questioning with the Defence Select Committee, where he stated that all our ship should have more offensive capability. Not sure how that lies with the interim missile being cancelled, unless he is referring to a holiday period, again!
Would be interesting to know the cost and feasibility of upgrading a handful of our Harpoons to batch IIs; or perhaps buying a dozen from the Aussies. IIRC they got a good deal from Boeing for their upgrade kit. I don’t know what work would be required on the launching systems to fire batch IIs but you might be able to finesse it through on the Babcock ‘maintenance’ contract.
https://www.armscom.net/news/boeing_to_provide_harpoon_upgrade_program_for_australia
Supposed to be fitted for but not with mk41 launchers
But will they have a decent offensive / anti-ship capability. RN warships always seem un-armed to me, in that respect. TLAMs as well
In a word JJ…NO
No. Zero AShMs for many years & 57mm main gun is way too light & short ranged. Any enemy warship will have blown ours out of the water long before we get in range to any effect. Even our Wildcats with very lightweight AShMs will probably be taken out before getting in range by enemy SAMs. Sadly the MOD & HMG believe their own spin.
As I see it T31 was optimised for a specific job; to be a patrol frigate in the Gulf; to escort merchant ships through the Gulf Strait, to see off Iranian gunboats, drones, early generation shore launched AShM and hijacking attempts. Ditto for the Bar El Mandeb straits off Yemen. Plus anti piracy off East Africa, plus possible small scale special ops insertion / rescue. Plus assist / defend a LRG humanitarian exercise or special forces insertion. Ditto for the Straits of Malacca and typhoon season in the Philippines etc. It is perfectly equipped for these roles and its Wildcat, Martlets and Sea Venom are well able to neutralise any likely opposition.
The following counts for the Royal Navy, the US Navy and European countries handle it slightly different BUT
FRIGATE
Typically provides anti-submarine capabilities to different degrees of effectiveness. The RN operates General Purpose and Anti Submarine frigates, the difference is if they have a towed array radar. Yes, frigates do have air defence missiles on board, but they are mainly designed for point defence, rather than long-range interceptions etc.
NOTE that with the incoming Type 26 it is likely that Frigates will also get an increased land-attack role.
DESTROYERS
The Royal Navy’s Type 45 destroyers now effectively only operate as an Air Defence platform, primarily intended for the Carrier Strike Groups. They have longer-range missiles and are paired with a radar better suited for tracking and taking out multiple targets at range.
Both frigates and destroyers have commonalities, such as short-range air defence missiles (mainly the CAMM missile, now also being introduced into Type 45) and for a while Anti Ship missiles (they aren’t being mounted anymore for numerous reasons).
My apologies for the wall of text, hope this helps 🙂
CAMM is short to medium range not just short range – it probably has a 50km range based on the fact that ASRAAM has demonstrated that performance and CAMM has the same body and motor.
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.
Either way its a lot longer range than either Sea Wolf or RAM (10km) and comparable with Aster 15 (30km) and ESSM (27km). ESSM Block 2 is 50km and CAAM-ER 60km.
Doesnt really have a difference for some navies.
France doesn’t have any Destroyer on paper, but the frigates (In fact, first rank ships, not all frigates) have the same roles than destroyer in the USN (Thats why they have the “D” hull NATO code).
The definitions change with times but mostly, to be a destroyer (from the US/NATO view), a ship must be able to escort others ship and having a full spectrum capabilities (Or close, since the land attack capability is not part of it).
As example, if you have only a short range air defense or/and not having a decent ASW capability, you can hardly be seen as a destroyer.
We can say real destroyer are the main assets (Or battle horse) of a navy and must be able to do all missions of a combat ship.
—–Next part is only my personal opinion—–
To me, a combat ship of 6000tons and more without all the capabilities, including land attack capability, is a not destroyer. And I will going farther with the numbers of weapons.
In 2021, having 16/32 major missile (Long range AA / Cruise missile), is not something decent for me…
And having 48 short range AA missile doesnt mean anything more, even more with the coming years and their lack of capabilities to react against modern supersonic/hypersonic threats.
Thats why I cry on these FREMM without cruise missile and their 2 empty potential Sylver A50/70.
The French and Italians have the Horizon frigate that is very similar to the T45 Destroyer. I think the term Frigate is also a political rouse to make expensive destroyers look more affordable. Remember the Invincible class aircraft carrier was originally called a ‘through-deck cruiser’.
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.
Ofc its shorter than building a new ship.
But having 2×8 VLS ready, even if empty, its a lot more easy…
Having a 800m€ to 1.2B ship with 16 or 32 VLS, I just cant understand…
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.
its not like the 32/48 VLS design doesnt exist…
I have seen a few of those before.
There are a few questions that I’d still like to see answered, but as Daniele and a few others will know, I do support this one. I’m particularly interested to see how the RN’s plans for autonomous vehicles will be integrated and where they’ll be forward-deployed. We have an inkling of course, but I’d like to see if some of our theories play out.
Hope you’ll be around for Lusty Friday Christmas Eve mate. 😆
I will be if I can. 😉
Five ships are not enough
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 the cold war, but by the 21st century in the US Navy the differernce between ASW and ASuW escorts had kind of vanished, and there are only “cruiser” “big escort” and “small escort.” (No hard and fast rules for these, either.) The general anti-surface ships stayed “Destroyers” in the RN, which eventually morphed into more specialised Anti-Air ships.
Outside the USN and RN it gets a bit complicated because at the end of the day it’s translating foreign terms. The French have no Destroyers, but have a lot of frigates with a classification system and a sort of light Frigate called an Aviso. The Germans stopped calling things Destroyers but still have Frigates that fill their old Destroyer role (baisically a flagship for a escort group of Frigates). The Italians are the closest European power to have a RN/US Destroyer/Frigate dicotomy (Catchatorpidineri and Fregatta) which broadly fit into the UK’s AA/ASW roles.
In general, Destroyers are larger than Frigates by a few thousand tonnes, but both types of ship have also absorbed a lot of “cruiser” into their jobs, so there is a lot of overlap. Ultimately it depends on which country you are looking at and when.
eg; The German Sachsen Class Frigates would almost certainly be classed as Destroyers in the RN and MM, but would be classed as Frigates by the Americans, Germans and French.
If the enemy submarine is under the ice then why are you concerned about it? ASW escorts are about protecting assets from Subs, or at most patrolling chokepoints (GIUK gap eg)
If a Russian sub is under the ice, our greatest ASW weapon against it would be an SSN.
Sadly we have far too few.
Those subs would most likely be Russian bombers which won’t be bothering Atlantic shipping.
Frigate is between half (diesel) and a quarter (nuclear) the price depending on each spec and cheaper to operate with more time at sea. Frigate can perform surface roles such as humanitarian, showing the flag, anti-piracy, etc…
The images appear to show a new type of trainable counter-measure launchers fitted p&s atop the forward superstructure. Items that have long been on the RN’s ‘wish list’ I understand.
They are Torpedo defence decoy launchers. look hard enough on T23 and T45 and they are also present in the same locations. They are tied into the S2071 torpedo detection and decoy system.
Thank you – I hadn’t realised this system was in service yet.
A lot of ship for a couple of pop guns, apparently limited ASW, no surface to surface, and a number (12? ) of Seaceptor. Also, as always, fitted for but not with T41 VLS. Just for once I would love to see a British warship fully equipped and able to take on anything thrown at her.
Hi Geoff,
I think the Type 26 will not have any ‘FFBNW’, unlike Type 45 and 31. That said, what will end up going into the Type 26’s Mk41 VLS remains to be seen!
The new scam will be they have the missile silos without the missiles and talk about potential land attack and torpedo missiles but not actually ever buy them.
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 it wants to be seen as powerful it builds cruisers the size of frigates.
Get them built asap. 6000 ton warship needs to be armed to the teeth. No more fitted for but never with.
FFBNW is a disaster waiting to happen. The capability gaps today are the capability gaps the RN goes to war with in the near future. As for ASW limitations look how it worked out for the Bacchante Class to see what can go wrong!
40mm no chance of NGS if required for Beach assault or the reason is that 4.5 fixed Tanked rounds weights 84lbs humping then around might be too much like hard work ,lucky it’s not a mk6 god I’m showing my age
People forget NGS was used as recently as Libya. Not an outdated concept.
Exactly, going back to 40mm sounds a cop out good for close in AA or SU when in Auto but no use in NGS in either Auto or LAS , Chris
Apparently fitted for but not with mk41 VLS.. makes more sense to fit it with? Have they also decided on the sea ceptor silo total? 12 is a bit risky. A drone capability and sonar of suitability would make this ship more than a pea shooting patrol boat
The question is which drone and what capability does it bring. If it’s just a drone with a camera attached then the extra capability is not that big
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.
Top speed 28kts. About the same as a 1960s Leander class frigate. Why no improvement over the decades?
It will most likely exceed 28 kts in sea trials but its specification is 28+ at design concept
It did.
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.
AA
Can you point out where in the future Marine Force they talked anout opposed landings?
You’re thinking the Russians invade the Ukraine and stop at the Channel and we do another D-Day, 4 years later, right?
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.
AA
I did wonder if you were being tongue but bit… darn.
Should Russia begin their Western European Tour in the Ukraine, we’ll all be digging our graves.
The QE’s are/were advertised as having a top speed of 25 knots. In reality it’s a hell of a lot faster than that. Don’t believe everything you read. Even from the RN !
True David. I know the QE’s top speed and the Americans refuse to believe it is actually a smidge faster than the Ford and Nimitz classes.
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.
Know it’s all about performance ,but just for the Record does anyone know if these Frigates will have the paint scheme like the River class ?
I don’t think so. That was to give the OPS a distinct identity.
Ok thanks mate ,do like seeing paint schemes on ships .But that’s not what it’s all about 😃
I think they look great too.
It looks a lot like the dutch and german frigates but with less firepower; the dutch frigates even have ff 127mm guns. Why just not buy those designs?
I imagine they picked the Iver Huitfeldt based Type 31 over other designs purely due to the need to Build them in UK Shipyards within the strict budget limits set by the MOD/Treasury.I doubt that the German or Dutch equivalents would get anywhere near to the budget offered.
Impressive ships; lightweight armament.
Armament can be added. Just get them built to budget and on time. If they are all singing and dancing now we’d be getting 2 or 3.
Best comment on this topic yet. Totally agree, plus they look very much nicer than anticipated.
Looks much more of an export potential than I’d 1st thought and that’s purely based on looks.
To coin a fraise “just anouther porcupine” the RN needs offensive capability, the eyes and ears also need a big stick to hit back with.
16 please
Then 8 type 26
And 6 type 46
Plus 5 river
Dream zone
I would be happy to see for the T31 future 24 Sea Ceptors and a Anti Ship missile. For the T31s and T32s possibly a containerised Tow Array, say five sets for both types. Apart from that I hope we can get these ships in the water as soon as possible.
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 is well suited for that. It is a cheap escort ship to free up t26/45 for CSG.
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
A zircon has a 500-600 mile range. You need over the horizon targeting, the ability to transmit that data from the detection platform to the shooter(kill Chain) You can add to that that Hypersonics havent hit a moving target yet.
Cold war ASMs such as Kitchen and Kingfish did M4+ so fast missiles are nothing new and the issues with targeting them haven,t changed since the mid 1960s when they came into service( A Kitchen derivative is still in service with Russian forces even now over 50 years later)
The targeting by the RN against enemy vessels still has the same issues that the enemy have, namely over the horizon targeting, data transmission and hitting a moving target at great range.
For a Harpoon engagement, which has a round a 60 mile as the crow flies range against a DD sized surface unit best practice is 4 missiles coming in from 4 different directions. You need to dogleg the approach courses, workout flight times to ensure a simultaneous time on target and factor in actual target course and speed, possible target course and speed changes, account for missile homing head activation range to ensure that the target is within the homing head look angle whilst minimising alert time on the targets EW systems, and make sure that all the missiles have different homing frequencies to ensure no mutual interference. Doing all of that means that the engagement range drops dramatically . Dog-legging can mean a Harpoon engagement can be down to 30-40 miles.
The Harpoon is now obsolete and despite the Authority spending precious money on maintenance, it will be withdrawn shortly.
The LRASM is a variant of the U.S. Air Force’s JASSM-ER cruise missile and shares many of its design features. 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. Unfortunately it will be far too big and expensive for the T31.
I fail to understand why the Authority – having issued a spec and (almost) invited bids – decided not to proceed with the Norwegian NSM. NSM does not emit infrared or radar waves that could be detected by enemy ships. Weighing in at 410 kilograms, it has a range of 185 kilometers and carries a 125 kilogram warhead. It would be capable of the Harpoon simultaneus attack profile that you discuss and would be a cheaper alternative to the LRASM. Capable of taking the attack to the enemy, it would also be a good compromise to defend any ship.
All our frigates and destroyers should be armed with an ASM system and torpedo tubes to launch Stingray. At Jutland many of our ships had torpedo tubes, but inexplicably failed to launch any
Agree. Especially on the ASM point for F35. That, and Typhoon, is where I would be buying NSM/LRASM. Aircraft for me are the main ship killers after an SSN.
That is a very blinkered way of thinking. You are extolling the use of basing future conflicts on the past and recent data.
If we look at the Exocet missile. This was sold to China, who then reversed engineered it calling the YJ83 and then sold it for export as the C803. It even uses a French made turbojet. This missile has been sold to a large number of countries and Iran was one of them. After some US pressure, China stopped selling it to them. However Iran reversed engineered it and called it the Noor. This missile has been used operationally on numerous occasion with a less then stellar performance.
The Israeli corvette INS Hanit got hit by one off Lebanon. Hezbollah actually fired two at it. The Hanit’s crew failed to recognize that steaming along the coast in full view was like showing a red rag to a bull. Due to lack of a perceived threat the crew had put the ship’s air defence system into standby. One Noor hit the ship near the waterline, killing four crew and wounding a load more. She managed to limp home though.
Off the coast of Yemen the Arlieh Burke destroyer USS Mason was sailing just within sight of land. She was painted by a Houti search radar and then attacked by a number of Noor missiles. Over a period of three days the USN believed the ship was targeted by 9 missiles. The ship’s Aegis system protected the ship throwing SM2s and ESSMs missiles at the missiles along with both active and passive countermeasures. The USN have not given a statement on how the ship’s system performed, however saying that a number of missiles were seen to crash into the sea. A few days later a number of Houti controlled search radars along the Yemeni coast were destroyed by cruise missiles, launched from the USS Nitze
As can been seen on the news, any belligerent group can get their hands on pretty sophisticated weaponry, especially sponsored by a Nation with hidden agenda. A country like Iran has been giving these groups the weapons and seen how they perform. Leading to further developments and tactics. A the USS Mason shows, a ship must be able to defend itself against modern threats, but it must also be able to kick ass when needed!
Today, the majority of modern Western anti-ship missiles (AShM) are dual hatted, in that they are also capable against land targets. The debate over whether a RN ship should have a modern AShM missile, is in my view missing the point. Without them the ship has no means of acting as a local deterrent or taking the fight to a belligerent when required. Its no good waiting for back up. A ship must be able to fight with what’s at hand. Jackie Fisher is probably rolling in his grave over what the Royal Navy has become today!
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. I’d much sooner put big weapons on the T26/T45 and get the F35bs on deck in numbers first with ASM, then making the T31 a weapons platform from the beginning.
We could argue all day but the T31 will not get ASM or a full load of sea ceptors. FACT.
We simply can’t afford it.
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 Eastern Ukraine who knows?
The Wildcat can only attack with Sea Venom misslies IF they can get within range to launch them. Most enemy warships SAMs would’ve engaged the Willdcat long before Sea Venom range was reached.
I’m sure the navy knows this and has acquired venom to take out fast attack craft/corvettes of the Iranian/houti terrorists in seas where the t31 will be operating. T 31 in day to day use will not need big offensive weapons as it not a front line warfare frigate. It is a cheap hull to patrol uncontested seas and give humanitarian support in disasters catch pirates and drug smugglers say hello to bigwigs and say look the RN is here if you need us. You don’t need/want ASW frigates or destroyers doing the mundane and very important non combat roles that the Royal Navy does and is renowned for world wide. We haven’t sent challenger tanks to help the NHS have we…..So why send T45/T26 to the Caribbean or do anti piracy duties. The only 1.5 navies who represent any real naval threat we would never be in a 1on1 engagement with them anyways as we stand side by side in NATO against them.
T31 is what it is, a cheap RN presence with light defensive armament for routine patrols in uncontested waters.
The RN does not have at present a cruiser which everyone wants to take the fight in peer on peer fights yet…T83 may be the ship that has the100s of vls for anti ship and land missles and air defence.
Great post, couldn’t have put it better
Agreed, with this kind of armory it is nothing more than an enlarged OPV. Put some big guns or missile launchers like the Israëli did on their corvettes on it.
‘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….
HMS Venturer not really going to be called the “Pet detective”
Brilliant ships but should have 16 mk41 vls for 32 Sea ceptor and 8 anti ship.
Have to laugh how none of these images show no 12-24Sea Ceptor silos or VLS. What are they hiding? However I do believe I can see some NSM type AShMs on the third image… unless my eyes are deceiving me. Nice refreshing images. If they want to bolster the fleet then order 1-2, it won’t break the budget.
hopefully it will turn out to be a great ship and in numbers to suit all.
only time will tell,
i had a dream that one day [april 1st ]lol
the royal navy will built a ship that is fitted for ? but not with an engine.
who knows.
merry xmas to all…
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.
Likewise, the 57mm with BAe ORKA smart rounds looks very capable.
The 57mm gun is a non-deck penetrating mount.
Still without radar director for the guns?
Maybe the experts can tell us but I don’t think there’s much difference between mm radars and short wavelength infrared / microwaves in the quality of the image you can resolve in foggy conditions.
X Band is ok.
“microwaves” ?
RN probably sees Type 31 as a sort of LCS and wants the 40mm and 57 to fight boat swarms.
Sorry, imprecise terminology.
X- band = microwaves.
I think the guns will also come in for drones and Houthi ASMs.
The main radar can support naval guns & the Sharpeye mk11 has an agile tracker option
modern EO/IR sensors can track through some cover
Interesting info. Thx
Just read the article about the new Bofors 40mm – I’ve got to say, it sounds pretty cool.
Watch the 57mm on u-tube mate, you will be well impressed!
Yep. and also look at the BAe ORKA smart rounds for the 57mm.
I would say that the 57 is a much better CIWS, especially if it uses the ORKA (one round kills all) shell.
ORKA rounds are not for anti missile, are for anti swarming boats.
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.
From information i read ORKA was developed at US request for anti swarm boat, probably will also work for anti aerial drone swarm.
Hi Alex. Yes, BAe’s ORKA was part of a US Navy request to make the Mk110 57mm autocannon more effective. As far as I know there were three companies involved: BAE with their ORKA, L3 with their ALAMO and Raytheon with their MAD-FIRES. All three companies went down the guided route.
The L3 ALAMO (advanced low cost munitions ordnance). It uses a programmable fuse and a novel method of altering its trajectory. It has been designed to engage primarily surface targets, though L3 say it should also be able to target helicopters and slower moving drones. L3 have shown a number of videos where it appears that the round uses an active radar seeker to guide it towards the target after firing. There is very little information available about what sensor the round actually uses or the exact method it uses to alter its trajectory in flight. Though the images appear to show either four mid-body radially spaced reaction jets or four mid-body push rods that project into the round’s airstream to alter the drag characteristics, thereby inducing a turning moment. Hence why it probably can’t hit a hard manoeuvring target. The US Navy are purchasing the round for their LCS fleet and FFG(X). Also the US Coastguard are also purchasing the round.
The Raytheon MAD-FIRES (multi-azimuth defense fast intercept round engagement system) is a step beyond the ALAMO and is more like the Leonardo DART. In that it is a sabot round to impart more velocity. It has been designed in collaboration with DARPA and is specifically aimed at target both fast moving aircraft and missiles. The MAD-FIRES looks similar to both the ORKA and DART rounds using forward mounted canards to alter the rounds trajectory. However, unlike ORKA it uses rocket assistance after being fired to extend its range and velocity. Again there is very little information on how the round is guided to the target. But it is described as a hit to kill interceptor. The USN have stated that they expect MAD-FIRES to be introduced into service by 2025, if not sooner.
There has been a lot of supposition in the US that the T31 will be getting the MAD-FIRES round, to extend the CIWS engagement range. With this round you are looking at double the engagement range of the 40mm. It should be able with the rocket assistance and smaller cross sectional area reach out further than the ORKA as well.
I imagine technical issues of getting a mere 57mm with a rocket+guidance
Having sensitive electronics robust enough to survive 36,000g acceleration I think is a pretty good achievement.
How can you sunbathe on the fo’c’sle with no guardrails???? 🤔😀
Carefully
Apologies for being a stick in the mud, but how can 5 ships be at the heart of surface fleet? There will at most only be 3 operational at any one time.
I’m an ex fusilier and I love being on the water…if I could choose again I would jump on that ⚓ ship
Any chance of 24 seaceptors and some SSMs?
None in reality. You will see reference to destroyers and frigates of several thousand tons displacement, and all combat ships have air defences.
Differences are range and variety of weapons
among other things
