The Boeing CH-47 Chinook is an American twin-engined, tandem-rotor, heavy-lift helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol (later renamed Boeing Helicopter, then Boeing Rotorcraft Systems, and now known as the Vertical Lift division of Boeing Defense, Space & Security).

Capable of a top speed of 170 knots (200 mph; 310 km/h), upon its introduction to service in 1962, the helicopter was considerably faster than contemporary 1960s utility helicopters and attack helicopters, and is still one of the fastest helicopters in the US inventory.

The Airbus Helicopters H215 (formerly Eurocopter AS332 Super Puma) is a four-bladed, twin-engine, medium-size utility helicopter developed and marketed originally by Aérospatiale, later by Eurocopter and currently by Airbus Helicopters.
