No end of Cold war make it relatively easy at least for a US aircraft B1-B2-B21(but ITTL B3?) or even a larger A12/FB22/FB23?With a PoD of 1964 have a 1000mn+ unrefueled combat radius strike aircraft replace the F111 and possibly TSR2 in service by 2000.
WOW, at $600 I can afford one!
Sorry, couldn't help myself.
Ok, so since you're looking for something for Australia, and something that would have been in production, that's really going to limit your options. I'm thinking maybe instead of the OTL's Hornets and Super Hornets, have Australia be willing to pay for some of the development of the F-22 Raptor and get them to operate Raptors and the proposed FB-22. The F-22As can replace their existing fighter squadrons, while the FB-22s can replace the F-111s in the strike role. This could work even better if you get the UK to actually accept the F-111K into service or continue the development and eventual acquisition of the TSR2. That gives the FB-22 a much larger proposed user base.
Have RAF buy F111 then pull out of Eurofighter (due to French gaining control/smaller aircraft) and get them to join US F22 and then have AUS buy in?have Australia be willing to pay for some of the development of the F-22 Raptor and get them to operate Raptors and the proposed FB-22.
