Never, never, never, never attempt to operate a Wokka from a crowded deck for an extended period. It wouldn't actually improve on a Merlin much - the main problems are limited altitude and cruise speed. To have a real MASC you need to get to FL200 (at least) and 300kts cruise, with a good 4-5 hours in the air. Wokka is not a brilliant solution for FRC (HEAVY) either. I know the Odiham SH lads have made it work on Ark & Ocean, but if you had the chance to fix the lift size / folding rotor problem, you would wouldn't you.....
CH53K (the new build Sikorsky) is a much better bet, but apparently it's been wished away on the grounds that its MAUM exceeds Oceans flightdeck. How long to people think Ocean will have left to serve by the time FRC(H) enters service? Another gash decision in DEC/DPA.......
V22 was looked at, but have you seen it fold?
