The Diamant''' rocket (French for 'diamond') was the first exclusively French expendable launch system and at the same time the first satellite launcher not built by either the United States or USSR. As such, it has been referred to as being a key predecessor for all subsequent European launcher projects. The head of the project, Charley Attali, received the Legion of Honour in 1965 for the Diamant.

Soyuz-U (GRAU index: 11A511U) was a Soviet and later Russian expendable medium-lift launch vehicle designed by the TsSKB design bureau and constructed at the Progress factory in Samara, Russia. The U designation stands for unified, as the launch vehicle was the replacement for the Voskhod rocket and several earlier Soyuz rocket variants. The Soyuz-U is part of the larger R-7 rocket family, which evolved from the R-7 Semyorka, the first intercontinental ballistic missile.
