The Boeing rating10::is a twin-turbine, tandem-rotor, heavy-lift transport helicopter.
After delivery of the first CH-47SD, launch customer pilots conducted system and functional checks with the aircraft as part of their orientation training. These flights included water landings on the Delaware River next to the Boeing Philadelphia factory. The Chinook is watertight and fully capable of landing on water for special operations and similar missions. The Chinook remains afloat even with the rotors not turning, and a special kit facilitates water operations.
