The Cree research missile was built by Cook Research Laboratories, and was used in the 1958/59 time frame by the USAF's Wright Air Development Center to test high-speed parachute recovery systems for missiles, drones, and re-entering spacecraft.

The Cree consisted of a large solid-propellant spin-stabilized rocket booster carrying three smaller test vehicles to speed and altitude. After booster burnout, the test vehicles separated and continued to coast about 9 m (30 ft) apart. Shortly after separation, the test parachutes were ejected from the tails, and the action was recorded by on-board cameras. About 30 seconds after test parachute deployment, a large parachute was released by each test vehicle for safe recovery of the recorded film. During the flight, a telemetry downlink relayed data on the missiles' speed, altitude and temperature. The Cree could test parachute systems at speeds between 2450 km/h (1520 mph) and 4890 km/h (3040 mph), and at altitudes between 8 km (5 miles) and 45 km (28 miles).
