The Lockheed CL-1201 was a design study by Lockheed for a large 6,000 ton nuclear-powered transport aircraft in the late 1960s. One envisioned use of the concept was as an airborne aircraft carrier.[1]

Although the Department of Defense does not appear to have records of the study's ultimate outcome, the design itself has nonetheless been cited in several sources.[2][3]

Perspective
The CL-1201 design project studied a nuclear-powered aircraft of extreme size, with a wingspan of 1,120 feet (340 m).[4] Had it been built, it would have had the largest wingspan of any airplane to date,[5] and more than three times that of any aircraft of the 20th century.
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 near the rear, where it would superheat the air passing through to provide thrust. The craft would be capable of remaining airborne for extended periods, with an estimated endurance of 41 days. At low altitudes, the jets would burn conventional aviation fuel. In order to take off, the plane required 182 additional vertical lift engines. These were similar to those used in the Boeing 747, a new aircraft at the time.
Two variants were studied, a logistics support aircraft and an airborne aircraft carrier. There was a rumored third variant, but information on such a model has never been made public.
The logistics support variant would have a conventional heavy transport role, carrying hundreds of troops and their equipment at once.
The airborne aircraft carrier would have carried up to 22 fighter aircraft externally and would have had an internal dock capable of handling two air-to-ground shuttle transport aircraft.
