AQM-38
From Wikipedia, the free encyclopedia
The AQM-38 is a missile developed by the United States of America.
[edit] Overview
The origins of the AQM-38 lie in the RP-70 radio controlled drone which Northrop developed in the 1950's. A purely developmental model, the drone was never produced in this form but did lead to the production of its RP-76 successor. The RP-76 entered service with the US Army in 1959, usually launched from F-89 Scorpion aircraft as a target for surface-to-air missiles. It was powered by an Aerojet solid-fuel rocket, giving a flight at high subsonic speed for almost 10 minutes. Controlled by an automatic system in flight, the missile could also be guided by radio. The fuselage was fitted with a fixed horizontal tailplane below the tail and three forward control fins. A two stage parachute allowed it to land once the mission was completed. A Luneberg lens was fitted to increase the radar signature, along with a RPTA-1 tracking aid.
The US Navy produced a modified version, the RP-78, which had a higher thrust rocket to allow speeds of up to Mach 1.25.
In 1963 the missiles were given the designations AQM-38A and AQM-38B. More than 2,000 of these missiles were built, with the last ones being retired in the mid-1970s.
