INTA-300
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.
Based on a Bristol Aerojet's INTA-255 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,<ref>Template:Cite journal</ref> having a thrust of 138.00 kN.
The intent of the INTA-300 was to be able to lift a payload of 50 kg to 300 km. With the help of the Bristol Aerojet, the Instituto Nacional de Técnica Aeroespacial was able to make a powerful enough prototype in 1981, after three unsuccessful launches. By the time of the fourth model's construction, funding had been cut.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
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 and reaching higher altitude.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
LaunchesEdit
The INTA-300 was launched by INTA six times between 1974 and 1994 from El Arenosillo.<ref name=":0" />
