INTA-300
Spanish sounding rocket. Two stage vehicle consisting of 1 x Heron + 1 x Snipe

AKA: Flamenco. Status: Retired 1981. First Launch: 1974-10-09. Last Launch: 1981-02-18. Number: 4 . Thrust: 138.00 kN (31,023 lbf). Gross mass: 503 kg (1,108 lb). Height: 7.27 m (23.85 ft). Diameter: 0.26 m (0.85 ft). Apogee: 250 km (150 mi).

In 1968 Spain's National Space Plan proclaimed the requirement for an indigenous sounding rocket that could carry a 50 kg payload to 300 km. Following initial experience with the INTA-255, British Aerojet assisted the Instituto Nacional de Tecnica Aerospacial in development of this larger rocket. The Aneto first stage burned for 3 seconds, followed by the Teide second stage generating 16.3 kN over a 16 second burn time. Stabilization was by four small spin motors at the tips of the fins. Development proceeded at a slow rate during the 1970's, culminating in a fully successful launch in 1981. But at that point funding for the project was cut off.

Funds again became available nearly a decade later. Three sets of motors remained in storage, and one set was test-fired to verify their safety. Two final launches were made with the remaining motors. These modified rockets, with heavier and wider payloads, were designated INTA-300B.
