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, 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.
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.
