1. RP-76 Marker
Inscription. RP-76 (Radioplane) was a subscale radio-controlled target drone, used in testing surface-to-air and air-to-air weapons at White Sands. It provided air defense personnel with experience in firing at a real target.

The target was air-launched from a fighter aircraft because of its small size and light weight. Plastic wings, nose section and aft fuselage were attached to the steel engine case.

Powered by a solid-fuel rocket motor, it had two exhausts at the sides of the fuselage. The RP-76 was controlled by an automatic control system with optional override by radio command. Notice its unique set of flying surfaces: three forward control fins and a fixed horizontal tail plane below the ventral vertical tail.

Because of its small size, it could fly only for eight to nine minutes. It was recovered by a two-stage parachute system.

Developed in the late 1950s by Northrop Radioplane division, it was used at White Sands from 1958 to 1961 by the Army, primarily for testing the Nike Ajax and Hercules. A total of 41 of the RP-76 targets were fired here.
