So drawing my entry for the DD challenge catapulted me into a naval era I seldom touch and that I know very little of, but the material I had to read to make heads out of tails of all of this caught my interest hard, and after finishing the Poplar-class I quickly started crunching numbers and sketching layouts for a proper Air Defence "Destroyer", the results of which you see here. Fluff is that this design is the second ship created from the ground up to be an AA escort for carriers and that it had to be cheaper to other County-like devices that seem to exist in every naval universe ever, and its built around a 2nd gen ramjet SAM and its launch and fire control system, which is very much like a more advanced Seaslug outfit. Terminal guidance for this pocket telephone pole comes in active and passive/home on signal versions, interception range was hoped to be over 100 nm. Lack of helicopter is entirely justified by them being provided by whatever aviation ship is being escorted.
I'm posting these in hopes that you enjoy looking at them as much as I enjoyed making them, and please do leave feedback and criticism if you can be bothered.
Hopefully my studying will provide ideas on how to refit them later on, but it really is untreaded ground for me.
