Lockheed CL-1201

The Lockheed CL-1201 was a design study by Lockheed for a giant nuclear-powered transport aircraft in the late 1960s. One role envisaged was that of airborne aircraft carrier.
Overview.
The CL-1201 design project studied a Nuclear-powered aircraft of huge size, with a wing span of . Had it been built, it would have had the largest span of any airplane to date.
The wing would be of crescent form, similar to the British Handley Page Victor V-bomber, but unlike the British design it was tailless.
Power would be derived from the heat generated by a nuclear reactor and transferred to four jet engines where it would superheat the air passing through to provide thrust. The craft would be capable of staying airborne for long periods of time. At low altitudes the jets would burn conventional aviation fuel. In order to get airborne in the first place it required 182 additional vertical lift engines.
Two variants were studied, a logistics support aircraft and an airborne aircraft carrier. There was a rumored third variant but information on that model has never been made public.
The logistics support variant would have a conventional heavy transport role, carrying hundreds of troops and their equipment to the battle zone.
The airborne aircraft carrier would have carried up to 22 fighter aircraft externally and would have an internal dock capable of handling two air-to-ground shuttle transport aircraft.
