There are three versions of LHD, based on displacement, each with 6 landing spots on deck and hangar capacity between 9 and 14 helicopters. 1 or 2 LHD and 3 to 4 LPD could probably cover lot of RN needs.
But it is questionable will MRSS replace all 6 ships on 1 for 1 basis, and somehow I doubt RN will go for additional flattops beside two QE class carriers.

1) Mixed with say 6 to 10 helicopters , vehicles and Landing craft
2) full LPH with say 16 Helicopters and 4 MALE drones using the vehicle deck as a hangar
3) full Logistics using both the vehicle deck & flight deck to carry stores and vehicles and the landing craft to move them
4) Drone mother ship operating UAV's , USV's & UUV's maybe all at the same time
Also in real terms we are now looking at replacing 1 x Albion , 3 x Bay & Argus if not just the 3 Bays and Argus

Re: Current & Future Amphibious Capability - General Discussion
As said many times Drones like TB2 & TB3 could operate from these ships but the point being as Tec moves on at pace
I can also flip the question and say why not have a flat top LPD ?

As a good base line both the Bay Class and Osumi class are the same size have about the same crew hold the same troops
We also know from first efforts by BMT that MRSS is looking at a 200 by 30 meter ship
Re: Current & Future Amphibious Capability - General Discussion
As far I can see the pitched Ellida design can operate two Merlins but only one Chinook. The Bay class cannot either. Albion can do two Chinooks or Merlin’s, that’s not bad, but given the need for a larger airlift capability why not think bigger?
A QE can operate up to six Chinooks simultaneously, 10 Merlins or a mixture - perhaps like HMS Ocean was a commercial version of the Invincible class, we could build another (or two)

Re: Current & Future Amphibious Capability - General Discussion
Really depends on what your priority is. If the focus is aviation and in particular helicopter operations then a flat deck is important to allow enough helicopters to be loaded without asking them to hold airborne until the assault force is formed up.
If your priority is vehicle and equipment off load then the lpd is preferred route due to 8 landing craft being carried.
And if the priority is follow on logistics then a lpd with a priority on store rather than troops.
Hence why we had ocean, and Albion and a bay. Specialist in each area.
If you read Julian thompsons book on the Falklands it’s worth nothing they needed 10 seakings for a company assualt by helicopters and it was something they practiced on Canberra on her two single spot flight deck getting them on and off the helicopter quickly enough.
And to move a light gun battery and the ammunition for a single battle by air required 85 seaking flights. Now Merlin and seaking aren’t that different lift wise.
So I would suggest unless there is huge increase in helicopter funding and numbers relying on aviation might not be the best option. But then who knows what the RM will end up looking like or be asked to do though I guarantee it won’t be what they first thought off.

Re: Current & Future Amphibious Capability - General Discussion
This is why we need 60 NMH with folding rotors
Re: Current & Future Amphibious Capability - General Discussion
That is never going to happen, where is the budget for that. Not just more helicopters but also for naval version. And I don't think there is a need for that. 2 FAA squadrons of Merlin Mk.4 already have more helicopters than all those 6 ships that will be replace could carry. And there is no chance that UK will replace them with 6 flattops, or that all 6 of them would ever be operated at the same time.
Having Apache and some Chinooks optimized to be used from ships? Ok, I can get that. Having all new NMH optimised? It would be waste of money as they would hardly ever be used in that role. It would be nice, yes, but it is not necessary.
Re: Current & Future Amphibious Capability - General Discussion
Let’s forget about six MRSS, even if they could be afforded a single class would either result in a compromised class that can’t do everything or gaps in capability. My vote, one large flat deck LPH, an additional FSS and confirmation of replacements for the Point Class (going back up to six).

Re: Current & Future Amphibious Capability - General Discussion
One LPH would not be enough. Current plan for RM is to have 2 LRG, one in the North and one in the South (Mediterranean/Indo-Pacific). Each one is supposed to have two amphibious ships. So if RN wants/could afford LHD/LPH, it would need at least two, one for each group. But even then it would probably mean only one available at the time. Considering that LRG was supposed to have one RM company with supporting elements it is questionable does it even need LHD/LPH. Sure it would be nice to have, but is it really needed? Also which size would should they be? Something like Osumi or Sen Georgio class could be sufficient but their size might limit option for drones that could be used so ... would it be worth it if it cost more than LPD?
Re: Current & Future Amphibious Capability - General Discussion
1) 3 Merlin’s not enough for a OTH assault, 2 LCUs too few for an other beach operation. Yes you could group together, but you still got a platform that is not good at either.
2) No, QE / POW can stand-in when it’s not available.
3) in terms of munitions, food, fuel no. Vehicles, artillery, etc perhaps, but the design hasn’t been confirmed as yet.

Firstly IMO forget LRG(S), stick to frequentlCSG deployments EoS. With QE/PoW + a large LPH two would be able to deployed at any time.

Re: Current & Future Amphibious Capability - General Discussion
I disagree that RN needs 4 LHP/LHD (of would even consider that) but nevertheless lets assume that 4 of them are ordered. It would be reasonable to assume that only two would be operational at the time, one for each LRG. So technically you would need just two air groups at the same time. As LRG does not have large manpower, basically some 250 marines, whole force could be transported by 4 to 6 Merlins in 2 to 3 flights, without using landing boats. So 24 Merlins should be more than sufficient for that, not to mention that whole force would probably not be transferred by air alone. Add to that 4 to 6 Apaches, and some Wildcats (both anti-sub and support) and you already have respectable air wing without need to any of future NMH.Tempest414 wrote: ↑18 Mar 2024, 09:27 Yes the 23 Merlins are more than the current 6 ships can carry but if we were to get 4 x 200 by 36 meter flat tops MRSS then we could in full load out carry 3 x that
Not to mention that 200 by 36 meter flattop would still have limited hangar and landing deck space, for example Mistral class which is closest to that have 6 landing spots on the deck and hangar that could operate 16 helicopters, so let say 6 Merlin HC.4. 4-6 AH-64, 4-6 Wildcats should already be optimal load.
So even in that scenario, which I don't think very likely to happen, 2 FAA squadrons should be more than enough for task and still have some helicopters for eventual third ship become active.
But again I don't think UK will order 4 LHP/LHD, even 1 would be a miracle.

Re: Current & Future Amphibious Capability - General Discussion
Having 3 out of 4 at any time will be really challenging. Maybe at some point could happen but on consistent rate highly unlikely.
Total number of personal could easily reach 500 but not from one Commando unit. Both LRU are supposed to have 250 marine from either 40 or 45 Commando on rotation, basically almost a half battalion (one commando is not able to provide two 500 strong LSU as total number of men in one if just over 600). To this base force other units could/will be attached, like detachments from The Commando Logistic Regiment, 30 Commando Information Exploitation Group, 24 Commando Royal Engineers and 29 Commando Royal Artillery. The South LRG will also have some 50 Dutch marines attached, not sure if temporary or permanently.Tempest414 wrote: ↑18 Mar 2024, 12:40 It also has been said somewhere that the RM could go with 4 x LSU's of 500 instead of 8 x 250

IMO the wisdom of the Wildcat AH1 is now highly questionable with lessons learned and the proliferation of drones in the battle space. Serious consideration must now be given to upgrading the AH1 to support the FCF without requiring the Apache under routine circumstances.
In the fullness of time that would require increasing the NMH purchase to somewhere around 60-80.
HMG may chose not to do this due to a lack of funding but that doesn’t mean it’s the right course of action, it’s just the cheapest course of action. This is one area that could clearly benefit from extra funding and therefore becomes a tangible improvement if defence spending was to rise.
