The RSA-3 LV was based on the Israeli Shavit rocket and was supposed to launch South Africa´s first satellite.
To cover its nuclear missile program South Africa funded its own space program and planned to launch its own satellite. Despite the international isolsation of the Apartheid-regime Israel provided the needed tecnology.
After the end of the regime in 1994 the whole project was cancelled.
Basicly the model is just a smaller version of the Shavit model with different textures. However, these might be inaccurate due to a lack of source material. Overall the model is fairly easy to build.
The scale of the paper model is 1:100.
