According to information published by the Radio Télévision Suisse on December 29, 2021, the Swiss Air Force may replace its Eurocopter AS332 Super Puma helicopters with Boeing CH-47 Chinook helicopters.
The Boeing CH-47 Chinook is an American twin-engined, tandem-rotor, heavy-lift helicopter manufactured by Boeing.
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.
