So maybe a large buy of F/A 18's for both a new (or at least new to the UK) carrier and as a new multi role air craft for the RAF ? I wonder how much money that would actually save ? The up side would be that the F/A18's would be in service during the cold war. I can also see a lot of down side especially vis a vis the Tornado F3 in the interceptor role. I also doubt this would be feasible from a political perspective.The only big one would be Eurofighter, and it’s already been suggested. The British R&D budget had already been slashed in 1981 and there wasn’t much left to cancel; theoretically they could scrap the Challenger 1, but the unit price for either the M1 Abrams or Leopard 1 is higher - if they did try to save money that way they would have to keep the Chieftain.
There might however be some interesting opportunities for collaboration with the Canadians and Australians vis a vis training and future upgrades.
