– a warhead and range. Propelled by nitric acid and kerosene, pressure-fed to the engine by a gas generator. R2 – a warhead and range, with a turbopump-fed engine fuelled by liquid oxygen and kerosene. R2S – a warhead and range, or a warhead over a range. Propelled by nitric acid and kerosene fuel with a turbopump-fed engine. This would be the first French strategic ballistic missile to go into production, bringing together all the technological advances of the first two variants. R2M – a warhead with a range, using a turbopump-fed engine fuelled by nitric acid and kerosene. This would essentially be a French version of the A9/A10 "Amerika Rakete" envisaged by von Braun, capable of striking targets as far away as Russia; its greatly increased range relied on using a detachable booster rocket and aerodynamic lift surfaces that would enable the rocket to reach a high altitude and then glide to its target. Outcome Although much work was done on the theoretical design of the Super V-2 and its fuel handling systems, the French government expressed little interest in funding practical development. The project was cancelled in 1948 and the development work was refocused towards the much smaller Véronique rocket. This ultimately led to the development of the Diamant rockets in the 1960s and the Ariane rockets from the 1970s onwards.
