INTA-300 diagram

The INTA-300, also known as the "Flamenco", was a two-stage Spanish sounding rocket. It consisted of a launch stage from the type Heron and an upper stage of the type Snipe. The INTA-300 was launched six times between 1974 and 1994. Based on a British Aerojet's model INTA-255 model of rocket, the INTA-300 is capable of reaching altitudes of 300 km (186 mi) alone and to 50 km (31 mi) with its maximum payload weight[1] with a thrust of 138.00 kN. The intent of the INTA-300 was to be able to lift a payload of 50 kg to the full 300 km which, with the help of the Bristol Aerojet, the Instituto Nacional de Técnica Aeroespacial was able to make a powerful enough prototype of the INTA-300 in 1981 after three unsuccessful launches. But by the time of the fourth model's construction, funding had been cut.[2]

When funds became available again in the 1990s, the fourth model of the INTA-300 was modified into a more efficient model dubbed the INTA-300B, capable of carrying heavier payloads with higher altitude-reaching capabilities.
