The RN has fixed wing ASW. Two Swordfish aircraft at RNHF. Expand this, call it a squadron, build four more replica Stringbags, find the ASV in the Museum and voila a stealth ASW platform that will cost very little to run. Worked 70 years ago, why not now?
+I forgot...give it to BAE and have a billion pound overrun...and be ten years late.
