The RSA-3 was produced by the Houwteq (a discontinued division of Denel) company at Grabouw, 30 km east of Cape Town. Test launches were made from Overberg Test Range near Bredasdorp, 200 km east of Cape Town. Rooi Els was where the engine test facilities were located. Development continued even after South African renunciation of its nuclear weapons for use as a commercial satellite launcher. Development actually reached its height in 1992 a year after nuclear renunciation with 50–70 companies involved, employing 1300–1500 people from the public and private sector. A much heavier ICBM or space launch vehicle, the RSA-4, with a first stage in the Peacekeeper ICBM class but with Jericho-2/RSA-3 upper stage components was in development, the RSA-2 was a local copy of the Jericho II ballistic missile and the RSA-1 was a local copy of the Jericho II second stage for use as a mobile missile.
