    If an aircraft carrier had been assigned to Force Z, what would have happened in history?

    While I was reading about a report abou Sinking of Prince of Wales and Repulse, I suddenly wondered what history would have been like if HMS Indomitable had been assigned to the Force Z without any damage, or if the Implacable Class Aircraft Carrier had been built earlier than the original...

    HMS Hermes as Sea Control Ship

    The saga of HMS Hermes is well known. But it might have been different if the RN had followed the US example and kept her as an ASW carrier or interim Sea Control Ship. The US were introducing the S3 Viking on to their attack carriers but were keen to get as many to sea as possible. HMS Hermes...

    You have 40-ish million pounds to build a CV for the RN early 60s...what does it look like?

    Not something I think fits in the alt-F11 thread but related to it, kind of. The RN is going to spend 16 million rebuilding Eagle, picking Tiger saves about 20-25 million over F-4 combine those two figures as your budget to build a new carrier with a 30 year hull life rather than spending 16 of...

    Supersonic Etendards instead of Crusaders?

    What happens if Dassault gets his hands on a jet engine that fits the Etendard and allows it to become a properly supersonic fighter? Could this tip the balance and see them ordered instead of F8 Crusaders?

    Britain in Vietnam

    One of Harold Wilson's achievements as Prime Minister was to resist President Johnson's pressure for Britain to make some visible military contribution to the Vietnam War.
