Fairey Ultralight tipjets-driven helicopter. I like it quite a lot, but I reckon that for ASW role it's likely just a manned equivalent of the DASH and justified only if the hangar of your ship can't be expanded to take anything bigger (even then there's always the MD 500 ASW); in the CASEVAC form it is, to my knowledge, the only chopper of its size and weight class that can carry a patient on a stretcher internally.
