SNCASE became the largest of the aeronautical ', with of space in six factories and employees. ( of the workforce came from Lioré et Olivier, along with 90% of then-current manufacturing contracts.) In 1941, during the Second World War, the Paris design bureaus of both the nationalized and the private aircraft firms were relocated to avoid capture. SNCASE acquired the failing SNCAM and moved its engineering operations to SNCAM's headquarters at the former Dewoitine factory in Toulouse. During the rationalisation of the nationalised Aircraft Industry during the 1950s, SNCASE merged with SNCASO to form

After World War II further work on autogyro's produced the SE.700 and SE.700A multi-seat Liaison autogyros, which were quickly over-shadowed by the rapid development of helicopters. SNCASE continued experimenting with helicopters with the help from a team from Focke Achgelis building the SE.3000, which was a French version of the twin-rotor Focke Achgelis Fa 223 Drache, and the smaller, more conventional, SE.3101. With this experience SNCASE went on to design the SE.3110 and eventually the SE.3120 Alouette which first flew on 21 July 1951 and broke the helicopter distance and speed records in July
