A 1953 General Electric study for a Convair C-99 cargo plane modified with nuclear turbojet propulsion. The pusher-prop engines were removed from the wing and replaced with a 65,000-pound AC-2 nuclear powerplant within the fuselage. This was equipped with two separate jet engines, giving a total sea level static thrust of 35,500 pounds. Two additional conventionally fueled J77 engines were mounted in the wings for takeoff thrust. A lead and polyethylene shielded crew compartment weighing 20,000 pounds protected the crew, giving radiation doses of 0.5 roentgen per hour.

    Presumably it was intended as a test bed, since there doesn’t seem to be any mention of shielding for the cargo? I mean, neutron activation of the payload seems like it’d be an undesirable outcome most of the time…

      I imagine the conventional explosives might act as a barrer. Urea was considered optimal for pulse-Orion if I remember Dyson jr’s book correctly.

      Neutron activation was generally not thought to be a problem. The reactor itself would have a lot of shielding, enough to drop the rads down to where activation would be minimal. You wouldn’t want to transport passengers, though…

    It would be an interesting model to hang from the ceiling. As a tanker, it could be displayed hooking up with the Hawk nuclear bomber, right over one’s bed.
