The Martlet 2G-1 was the absolute minimum gun-launched satellite vehicle. Conceived when the HARP project was under threat, it was a seven-inch diameter, two-stage solid propellnat vehicle that would be sabot-launched from the HARP 16 inch gun. Its total payload in orbit would have been just two kilogrammes - ideal for today's planned nano-satellites. Unfortunately even this minimum orbital launch vehicle could not be demonstrated before the program was shut down.

During the last year of the HARP program, when it became clear that further funding was not forthcoming, and that the goals of the Martlet 4 program were not to be realised, full efforts were diverted to developing a Martlet 2G-1 orbital vehicle (GLO-1A). It was felt that if a satellite - any satellite, no matter now small - could be successfully gun-launched, that it then would be possible to encourage further funding, either public or private, which would permit the orbital goals of the HARP program to be realised. Unfortunately time and fate were against HARP and the project was closed down on June 30 1967, only a few months before an orbital 2G-1 could be flown.


LEO Payload: 2 kg. to: 185 km Orbit. at: 13.0 degrees. Total Mass: 500 kg. Core Diameter: 0.3 m. Total Length: 4.3 m.
