Re: Albion Class Amphibious Assault Ships (LPD) (RN)

Such a fantastic design, just lacks the ability to embark 4-6 medium helicopters. I've been wandering that if we can add a "2 Merlin long" hangar in place of port-side LCVP davits. Maybe some additional width (sponson) will be needed, by 1-2m extension. But, by having a long-box 32 m long...

Re: Current & Future Escorts - General Discussion

I'd go for gap filler 2 - build a couple more type 26s. Problem with OPVs is they don't actually fill the gap. The trades you really need to retain are the people doing the high end integration. There's not much of that work on a simple OPV. BAE in Melbourne were offered a couple of simple OPVs as ...

Re: Current & Future Escorts - General Discussion

Much can happen between now and 2035. Much depends on the elephant in The room, which is Successor. Reasonable assumptions about current programs will lead to some financial space in 2032-34. Design doesn’t cost much if you’re importing the missile. I think 83 will start on time and if there’s a de...

Re: Current & Future Escorts - General Discussion

Anyway, I think the higher priority now is to design a new OPV. River B1 dates back to 2000, and River B2 basically reuses its design. So it will be 35 years old design when it might be required to fill the gap between T26 and (delayed) T83. As T83 delays, BAES design team also need some "train...

Re: Current & Future Escorts - General Discussion

I do agree for the most part type 31 and the RB2's were a knee jerk reaction however we now have a number of roads too chose from 1 ) build more type 31 and RB2's for the for the C2 & C3 fleets 2 ) design type 32 to be a 140 meter multi role frigate with 1 x 57mm , 2 x 40mm , 24 VLS , 8 to 16 N...

Re: Current & Future Escorts - General Discussion

On plan-B. Plan-A: find a resource to design T83 on time This will deeply depend on what kind of AAW system it will adopt. Remain on Aster world, or go for AEGIS world. Note that, AAW system development costs even more than the ship design cost. If RN accept going with AEGIS, or just "import&qu...

If we wre starting with blank sheet of paper, I would have loved to see RN equivalent of Dutch Holland-class or even French Floréal-class - something in the region of 105-110m length (for operation of helicopters), 3,500-4,000 t displacement, 4-4.5m draught. i.e. somewhere in between the current T3...

Re: Current & Future Escorts - General Discussion

As 2023-2033 plan has zero commitment to T83 development activity, we need to consider several "plan-Bs" now. Motivation In the past, 2013, we all remember what happened when T26 start-of-build delayed for 3 years. No plan-B, and to keep the shipyard alive, RN was forced to order 5 River B...

Re: Current & Future Escorts - General Discussion

If T83 design delays, T32 banned, and T45 needs to be life-extended, there are two independent problems. 1: how to keep the design team working? I'm afraid that T83 delay and T32 banned simply means the design team will see degradation of capability. They can do concept design, but no detailed desig...

So can we now agree that type 26 program cost to date is 9 billion and on that bases we can remove 2 billion for design and initial costs leaving 7 billion meaning type 26 build cost is about 875 million per ship but it could go up if the 5 sets of GFE including 5 x Artisan Radar , 5 x Hull and tow...

?? Sorry I could not understand your calculation here.
Initial 3 hull "average" cost is higher than 5 more hulls. It includes many detailed design costs and initial cost, I understand?

As said before the cost for the first 8 ships stands at 1.02 billion per ship We are discussing the cost to build each ship. So either you are claiming the entire 3.7billoin of the B1 contract was for build. Which you will find impossible to support with any published material. Or you are deliberat...

They are about $2m a pop and as seen most recently in Syria you have to fire a shed load. Didn't the US fire over fifty at one airfield. And firing "over fifty" FCASW will be prohibitably expensive, while there shall be "over fifty" targets to hit when a hot war happens. And, no...

Re: Current & Future Escorts - General Discussion

The other thing to remember about TLAM is it isn't much use if the enemy has decent anti air. A 5m long 1500kg missile lumbering along at 550 knots isn't very stealthy. And therefore very cheap. FCASW will cost at least three times (subsonic version) and nearly ten times (if hypersonic). Supersonic...

Re: Current & Future Escorts - General Discussion

But, 8-cell VLS is very cheap, but mission integration and electronics, software are expensive. For what we shall waste that money to have, say, ~20 ships each with 8-cell VLS = 160 cell, when we probably can get ~10 ships with 32-cell each with similar money = 320 cells?
