Q17391
The Antarès (OPd-56-39-22D) was a French multistage rocket designed by ONERA for reentry studies. In the late 1950s, the study of missile warhead reentry necessitated the development of a more robust rocket than the existing OR, VD and OPd series. The Antarès rocket, designated OPd-56-39-22D during its developmental phase, was designed to facilitate the study of kinetic heating on objects flying at speeds up to Mach 7.
