Take it the RAAF F-35 are not the B model are they? There is no B model within the contract are there?
As HMAS Canberra appears to have ski jump ? But its strictly a helicopter carrier unless they will have occasionally USMC AV-8B Harrier II PLus cross decking or detached as Ark Royal did on her last deployment stateside?
Chopper, all of the F-35s on order for Australia are A models- conventional landing. There is much speculation that a future buy could be a squadron or so of B's- the V/STOL model.
Australia could buy F-35B - IHS Jane's 360
I think the ski jump on the Canberra is a major hint of a B purchase.
