    Apollo Lunar Programme continued

    In an alternate world where the USA avoided the trauma of Vietnam and LBJ won a second term the Apollo moon and earth orbit programmes continued into the 70s as originally planned. Assuming that a similarly pro Apollo President had succeeded Johnson in 1973 and the US economy continued to...

    Zumwalt "borrows" (and adapts) European carrier designs...

    ... instead of re-inventing the wheel in the 70's. The idea is to blend together, Zumwalt "cheaper decks" (SCS / VSS / CVV) and the too few carrier designs from Europe. To bolster NATO fleets on one side, and the USN on the other - more flattops on both sides of the Atlantic. That is...

    JPL "spare" planetary program, in the 70's.

    As said in the title... all the robotic planetary missions launched in the 70's left a spare spacecraft on the ground (and later, at the NASM aerospace museum). There were good reasons for that - providing spares - ground testing - backup in case of failures (Mariner 8...) Soooo ...by 1978...

    Ireland's SST that never was

    Back in the 1960s Boeing was telling everyone that its Supersonic 2707 transport would be the must-have airliner for the 1970s. Some 26 airlines took out options on the plane. There is a comprehensive thread about the US designs on this site, but no illustrations of the artwork Boeing must have...

    Leopard 2 prototypes

    During the development of Leopard 2, about seventeen different hulls (PT series) and turrets (T series) were built. At least two of the hulls (numbered PT11 and PT17) were fitted with hydropneumatic suspension and only six roadwheels. I managed to find only one small picture of such hull...

    General Dynamics Fort Worth F-16 derived GAU-8 gunship concept (G.F.G) from 1976

    Thanks to Air21 over at What If Modelers: Thought this design was already mentioned in an existing SPF thread, but I couldn't locate it. I'm wondering if this design originally grew out of one of the 'Model 402' studies. Also, I wonder if there was a late 1970s semi-official USAF requirement...

    MIAG (Mechanized Infantry Assault Gun) - MICV-70 derived assault gun proposal

    An excerpt: Note: Given the date and lack of dismounts among other things, I suspect that this was the early incarnation of the MIAG proposal. EDIT: Ack, blundered on the title! I put down MIVC-70 instead of MICV-70 and only noticed it now!
