Wow, just wow!
I just came across a cabinet memo in the Australian national archive referencing a report I am reading referencing the defmins inquiry into the way forward after the UKs decision to retain Invincible post Falklands.
NAA A10756, LC3015
Replacement Aircraft Carrier for HMAS Melbourne [Submission Nos. 4305, 5234, 5318, 5322, 5333, 5338 and 5354 refer]
Invincible, Garabaldi, modified LPH, SCS, modified merchant ship options etc. I knew existed, but didn't realise we were revisiting all of them and I had no idea a conventionally powered CdG and a Ctol LHA/LHD (Tarawa/Wasp) existed let alone were being looked at! The CTOL option were expected to offset their greater acquisition cost by saving money operating existing types, including F/A-18s.
