    Different British nuclear reactors?

    I keep bumping into this from different angles, its technically very interesting to me so I'll ask the question here and see what happens. In the late 50s Britain was looking for a more commercially oriented nuclear power reactor type to follow on from it's operationally successful but not very...

    Seacat performance

    We have discussed Seaslug performance in some detail and speculated about what Seacat 2 might have been like, but original Seacat has not received attention. Widely fitted on British warships during the 1960s and 1970s its only combat use was during the Falklands war in 1982 where 40mm guns...

    Royal Navy frigates in the 70s

    The saga of the Royal Navy's carriers after 1966 has been the main focus of interest here, but the workhorse of the RN then as now was the frigate. By the 1970s the RN had plans to replace its Type 12 Leander class frigates with the larger all missile armed Type 22. Leanders were designed...

    NATO helicopter gunship for the 70s

    Although the excellent AH1 Cobra was deployed to Europe in the 1970s and received TOW missiles to help it kill Soviet armour, noone else in NATO could afford it. That left W Germany sticking six HOT missile launchers on its Bo 105 light observation helicopter and the British Army SS11 missiles...

    Swiss Panzer 74 info

    Hello all. I have been reading up on Swiss MBT programs and concepts in the last few days and I noticed that Secret Projects does not yet have a thread dedicated to the Panzer 74 proposal. I am aware of the Tank Encyclopedia article on this matter but I thought I'd ask this forum.

    Moon 1970s

    As the US looks to go back to the Moon with Artemis my question here is, what might have been feasible in the 1970s to keep the US sending manned expeditions to the Moon?
