In 1958 the French Army, in cooperation with a Dutch governmental research institute, held some experiments with nerve gases in the Algerian Sahara Region.
The ammunition the French used were several 150 mm surface-to-surface rocket swith two engines (“projectiles autopropulsés par deux engines”). Maybe, just maybe the rockets were German ‘beutewaffen’. The rockets were of course modified in order to take warheads filled with nerve gases.
Can somebody please help me identifying these 2-engines 150 mm rockets?
