Lockheed CL-288

The Lockheed CL-288 was a conceptual interceptor aircraft based on the Lockheed F-104 Starfighter and powered by two wing-mounted engines. GlobalSecurity.org's list of Lockheed design numbers places it in the CL series, which it describes as Lockheed California temporary design numbers, and calls it an intermediate long-range high-speed interceptor project, an F-104 with wing-mounted jets. The same list gives a similar entry for the CL-346, another F-104 derivative with wing-mounted jets, so the design belongs to a group of Starfighter variants that Lockheed studied with the engines moved out onto the wings.
