HISTORY: While only built in relatively small numbers (though it is still built under licence in China), the Super Frelon has the distinction of being the largest helicopter to be built in quantity in western Europe. The Super Frelon was developed from the smaller, mid size SA 3200 Frelon (Hornet), the first flight of which was on June 10 1959. The Frelon was intended to meet French military requirements for a mid size transport helicopter, and although four prototypes were built, it was not ordered into production. Instead the Frelon formed the basis for the much larger Super Frelon which Sud Aviation developed in conjunction with Sikorsky. Sikorsky helped primarily with the development of the main and tail rotor systems, while Fiat of Italy assisted with the gearbox and power transmission (and built those parts for production aircraft).
The SA 3210-01 prototype Super Frelon flew for the first time on December 7 1962, while 99 production aircraft were built in three basic models. The SA 321G was initially operated by the French Navy as an anti submarine warfare and sanitization aircraft for French nuclear armed submarines, equipped with radar, dunking sonar and torpedoes. Similar SA 321 GMs and SA 321 Hs were delivered to Syria and Iraq respectively. The SA 321F and SA 321J were civil variants, while the SA 321J is a utility transport. Non amphibious transport versions were exported to South Africa (SA 321 L) and Israel (SA 321K), while Libya's SA 321 Ms were delivered for SAR and logistics support. French production ceased in 1983, while Changhe in China continues to licence build the multirole Z-8 development.
