According to Wikipedia: "The Aerospatiale SA 330 Puma is a four-bladed, twin-engined medium transport/utility helicopter. The Puma was originally manufactured by Sud Aviation of France, and continued to be produced by Aerospatiale. The Puma was also license-built in Romania as the IAR 330; unlicensed manufacture of an advanced derivative, the Atlas Oryx, was also conducted by South Africa. The Puma was a commercial success and was quickly developed into more advanced models such as the AS332 Super Puma and AS532 Cougar, manufactured by Eurocopter since the early 1990s; in this manner descendants of the Puma remain in production into the 21st century."
