I'm not sure symmetry is a requirement and I would argue that 8 of everything isn't affordable either.Poiuytrewq wrote: ↑07 Jun 2023, 21:30Why not?
However, an adapted T26 that retains the superior ASW capability is still top of the list if RN can pull it off.
IMO a T26 based AAW optimised T83 would change everything for RN especially if 8 were built. That would allow the T83’s to concentrate on the CSG exclusively providing both the AAW and ASW required. RN could then use the T26’s for a multitude of other taskings and not constantly be tied to the CSG and TAPS alone.
Eight of each looks about right.
8x T83 (T26 based combined AAW/ASW)
8x T26
8x T31 GP
8x OPV
Excellent symmetry and affordable.
As to reusing the T45 hull and I assume propulsion I think that ship has sailed. It was an effort and compromise to fit all the high tech IEP tech into a hull the size of the T45 and if you went with IEP today there have been advances in DC electrical technology which arguably makes the AC based T45 system obsolete. There would need to be an awful lot of rework just to bring it up to date.
As to reusing T26 if you were happy to give up the Mk45 gun and automated magazine, Integrated mission bay and Chinnook sized flight deck to allow fitment of a second missile silo and a large AAW capable radar then it is feasible to produce a T26 sized AAW destroyer.
If you want a 12,000t Type 055 cruiser then starting with a blank piece of paper would be better.
