I would love to know where this "significant influx of Aircrew and Groundcrew" is going to be sourced from. We haven't enough of either to man the existing fleets.
Oh and why would an MMA need to be based on the coast anyway? Given the incredibly low frequency of Soviet submarine deployments to NORLANT in the last 20 years, it's hardly a solid case for re-opening a seaside airbase way up North. IMHO ASW is quite possibly not going to be the full time primary duty of the aircraft.
