In 1975, the US Navy had expressed interest in a low-cost alternative to the Grumman F-14 Tomcat. General Dynamics proposed a navalized YF-16, with BVR radar, which was not part of the original planning for the USAF. The aircraft was briefly painted in a two-tone blue/light-brown color scheme for naval evaluation purposes. General Dynamics refined the proposal into a single-seat F-16, based on the two-seat F-16B - with the space ordinarily occupied by the rear seat used for increased avionics or fuel. On May 2nd, 1975, the Navy announced that they had decided not to buy the navalized F-16, but opted instead for an aircraft developed from the YF-17, which was eventually to emerge as the McDonnell Douglas F/A-18 Hornet.
