The LTV L450F, also known as the L45ØF, was a prototype quiet reconnaissance aircraft, developed by Ling-Temco-Vought in the late 1960s for use in the Vietnam War by the United States. Based on the airframe of a Schweizer 2-32 sailplane, the aircraft flew in 1970, and was developed into the XQM-93 reconnaissance drone before the project was cancelled.
