The Boeing Vertol CH-46 Sea Knight is a medium-lift tandem rotortransport helicopter. It is used by the United States Marine Corps(USMC) to provide all-weather, day-or-night assault transport of combat troops, supplies and equipment. Additional tasks include combat support, search and rescue (SAR), support for forward refueling and rearming points, CASEVAC and Tactical Recovery of Aircraft and Personnel (TRAP). The Sea Knight was also the U.S. Navy's standard medium-lift utility helicopter until it was phased out in favor of the MH-60S Knighthawk in the early 2000s.

Canada also operated the Sea Knight, designated as CH-113, and operated them in the SAR role until 2004. Other export customers include Japan, Sweden, and Saudi Arabia. The commercial version is the BV 107-II, commonly referred to simply as the "Vertol".Piasecki Helicopter was a pioneering developer of tandem-rotor helicopters, with the most famous previous helicopter being the H-21 "Flying Banana". Piasecki Helicopter became Vertol in 1955 and work began on a new tandem rotor helicopter designated the Vertol Model 107 or V-107 in 1956. The V-107 prototype had two Lycoming T53 turboshaft engines, producing 877 shp (640 kW) each.The V-107 was then put through a flight demonstration tour in the United States and overseas. In June 1958, the U.S. Army awarded a contract to Vertol for ten production aircraft designated "YHC-1A".During 1960, the U.S. Marine Corps evolved a requirement for a twin-turbine troop/cargo assault helicopter to replace the piston-engined types then in use. Following a design competition, Boeing Vertol was selected to build its model 107M as the HRB-1, early in 1961.^[n 1962 the U.S. Air Force ordered 12 XCH-46B Sea Knights with the XH-49A designation. but later cancelled the order due to a delay in the delivery schedule. They opted for the Sikorsky S-61R instead.^[The Marines also received CH-46Fs from 1968 to 1971. The F-model retained the D-model's T58-GE-10 engines but revised the avionics and included other modifications. The CH-46F was the final production model.The Sea Knight has undergone upgrades and modifications. Most of the U.S. Marine Corps' Sea Knights were upgraded to CH-46E standard. The CH-46E features fiberglass rotor blades, airframe reinforcement, and further uprated T58-GE-16 engines producing 1,870 shp (1,390 kW) each. Some CH-46Es have been given double fuel capacity.
