Sorry mate,
but if we have no navy, why would we need ASW and convoy protection. Surely, with 500,00 members, the Civvies could get the USN to do that. I don't think our tinpot fleet, and Daihatsu carriers are going to achieve much in that direction. Furthermore, if UK PLC decides we need to protect convoys, and do everything else, they can bloody well pay for it ALL.
