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?

Then again one of my former employers, 14 years ago published a report on ADF procurement with talk of having a largish helicopter carrier with ability to even launching the RAAF F/A-18 fleet bringing back the carrier capability they got rid off when selling off HMAS Sydney and the A-4 and MB339 fleet.
