Lockheed CL-1200
 The Lockheed CL-1200 Lancer was a late 1960s company-funded proposal for a new and improved F-104 Starfighter. It was intended for the export market and was in direct competition with the Northrop F-5E Tiger II Dassault Mirage F1 Northrop YF-17 and the McDonnell Douglas F-4F Phantom. Lockheed hoped to capitalize on its F-104 production experience through commonality of parts and systems and minimize expenses by reusing tooling jigs and existing factory facilities.
