Re: River Class (OPV) (RN)

1: Measuring from the River B2 dimensions, and facing the fact that Wildcat cannot fold its tail, the hangar shall be as long as 15 m, and hence the flight deck shall be as small as 18 m or less, if no hull extention is done . 2: For blue water, a ship with length less than 110 m is reported to be n...

Re: River Class (OPV) (RN)

River B1 HMS Severn in training. These basic but critically important tasks covered by "cheap to operate" but "has good sea-keeping" OPVs gives us good insights what a cheap patrol vessel can achieve. OPVs are the real work horse of RN. https://twitter.com/NavyLookout/status/1465...

Re: Border Force Cutters.

UK Ministry of Defence Police (MDP) has ordered 18 15m-class fast patrol boats. Where are the current fleet is deployed/assigned? Can these vessels cover the "increasing demands" in fast patrol crafts? In other words, what is the "work share" between BF cutters, RN fast patrol bo...

Some part of me thinks she can work more.
Some part of me thinks she worked much longer than originally planned.
Some part of me thinks can it be exported, with upgrades?

Re: Scimitar Class Fast Patrol Vessels (RN)

USVs have a role to play for surveillance, MCM, Survey and increasingly offensive actions, but by definition they do not carry people. Challenging and boarding suspicious vessels still need humans and in the grey zone we will still need people to make decisions. I see UK/BOT ports becoming more lik...

@Donald-san, the threat levels in the Caribbean, western Med and the Falklands is low. I’d argue that the threat levels off the west of Africa is medium, similar to areas EoS. Whilst, I’ve given up arguing for a 57mm gun that could be a permanent and appropriate level of protection, the ability to ...

The R2 won't be taking on Corvettes, they will be tracking and intercepting drug runners, people smugglers and anti piracy patrols. All of which can be performed with UAVs and DS-30 MkII. If they where to take on corvettes they would need armed with anti ship missiles, a better radar and CAAM For p...

Re: Scimitar Class Fast Patrol Vessels (RN)

Repulse wrote: 20 Nov 2021, 09:32 Scimitar class up for disposal. A real shame IMO as the need of a fleet of fast patrol craft is increasing IMO.
At where "the need of a fleet of fast patrol craft" is increasing? With patrol USVs coming, I think any such needs will be filled by USVs? (just genuine question).

Jensy , can’t explain it, but I actually prefer the 100m version. Can imagine it as a RM company level platform with fast boats and a couple of Wildcats. It's funny you say that. I also had a preference for the 70m and 100m variants but for less demanding roles Think it was the larger dock and flig...

Re: Current & Future Amphibious Capability - General Discussion

Why not BMT Caimen90? Lots of LCU's slightly larger, based on Caimen90 are now in production for US Army. It is (so so) fast, has a capacity to replace LCU Mk.10. If would be even nice to use the same design as built for US Army.

Re: Type 31 Frigate (Inspiration Class) [News Only]

It really depends on how fast you really believe Babcock could build 8 Frigates (T31) effectively starting from scratch. Even if Babcock maximises efficiency it will take at least a decade before the steel can be cut on the T32’s. In real terms that results in the first T32 commissioning around 203...

Re: RN anti-ship missiles

Have difficulty getting my head around the idea of an SM-6 on a Type 31 frigate :? ... By the way, is the SM-6 hypersonic? I thought not. The SM6 block 1B will have a larger booster, 21in vs 13in ?, plus other upgrades to make it hypersonic. Exactly. Difference between SM-6 Blk1A vs SM-6 Blk1B rese...

The problem with the “Interim” solution may be as follows. Not worth adding to T23 due to:- a) Limited life left in the platform. b) Reduced availability alongside (to be fitted with) as the numbers of T23 reduce, but demand for deployment is maintained or increased. c) Avoidable Spend. Not worth a...

So, if I-SSGW is to be canceled, can UK develop a long-range SeaVenom-ER by 2027? 1SL gave a very reasonable account of why spending up to £500m on I-SSGW was sub-optimal. It’s makes complete sense. Don't agree. It was not convincing enough to justify "capability gap", for me. Of course, ...

Pound for pound (kgs) you don't seem to be getting a great deal; perhaps £ for £? More than likely cost is the major difference. The AWS-10L has slightly shorter detection ranges that the AWS-10 (so it would pick up an MPA at 85km, rather than 100km and a missile at 30km instead of 35km for instanc...
