The Matra R422 missile is a semi-active electromagnetically guided surface-to-air missile designed by Matra (France) in the 1950s.
The R422 was developed by Matra as part of the French army’s SA20 program for long-range surface-to-air (SALP). It was then in competition with DEFA PARCA and SNCASE SE.4400. It had to be able to intercept bombers flying at an altitude between 3,000 m and 11,000 m and at a speed between Mach 0.5 and Mach 2.
