The SA.3210 Super Frelon was developed by Sud Aviation from the original SE.3200 Frelon. Sikorsky was contracted to supply the design of a new six-bladed main rotor and five-bladed tail rotor. Fiat supplied a design for a new main transmission. The first flight of the Super Frelon was 7 December 1962. A modified prototype Super Frelon helicopter was used on July 23, 1963 to break the FAI absolute helicopter world speed record with a speed of 217.7 mph (350.4 km/h).
