RN should have never forgotten when fighting a war the numbers of ships are of critical importance and the way to achieve that is to keep size and cost to the practical minimum and not lose touch with reality as the RN did by over specifying the T26 which ended up twice the size of a T23 and costing £4.7 billion for three ships that are not even Tier 1.
I think you are saying RN must go back to the 1970-80s concept of "small escorts in number". Typically, T42, T22 and T21. T23 is also in the same league. Good point to discuss. If so, RN must NOT go with T83 "cruiser", but must go with "T46 (47?)" AAW destroyer as a direct replacement for T42. NOT top-level AAW capability, no ASM, minimum ASW, but in number. I agree here.
T31 "as is" is a very basic GP frigate. For me, it is a frigate-sized hull with heavy-corvette level armament. Is that level "good enough" for you?
If 1-st tier level of AAW capability is needed (say, frigate with long-range AAW missile AND short-rage AAW missiles in number), the same can be applied to T26 B1. With higher level of CMS, 48 CAMM and 24-cell Mk.41 VLS already there, up-arming AAW capability of T26 will be much cheaper than doing the same to T31.
If T31 with "24 CAMM" is what is needed, it will be cheap. And, this means T26 is already good enough in AAW, while providing 1st-tier ASW capability T31 will never provide (reflected into the cost).
Note that I agree this part of your argument is very good point to discuss. Not denying your argument. And, what is important will be "what level of AAW, ASW and land-attack capabilities" is the minimum needed?
- "Smaller hull to make it cheap" dogma is thrown away by RN. T45, T26, and T31 all are designed to handle future growth margins. On the other hand, French navy is building FDI in small-hull dogma. Interesting to see how it evolves.
- What is making T26 expensive was touted to be the mission bay and 24-cell VLS. As an ASW asset, these are not needed. Actually, I was saying so. But, current mood is that, RN says mission bay is must, many here states Mk.41 VLS is must. It was correct?
- How the program proceeded (including the "wasted" £650M for River B2s and 3 years of "study" wasting similar amount of money), must be criticized. Not going for frigate factory, as well. "Too slow" is what the RN admiral also stated as a negative side of T26. It must be corrected, I agree.
- But, T26 is now in production phase. RN can "add" 1st-tiear escorts with "less than £1B" cost easily (because all the design and initial cost, which costs as much as 3-unit cost in both FREMM and FDI (by French government)) is already paid. (As such, "cutting" one T26 will never provide £1B+ money)
