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). The CH-47 is among the heaviest lifting of Western helicopters. Its name, Chinook, is from the Native American Chinook people of Washington state.
The 1st Cavalry Division had brought its organic Chinook battalion (three Chinook companies) when it arrived in 1965 and a separate aviation medium helicopter company, the 147th, had arrived in Vietnam on 29 November 1965. This latter company was initially placed in direct support of the 1st Infantry Division. CH-47 crews quickly learned to mount an M60 machine gun in each of the forward doors. Sometimes they also installed an M60 or M2 machine gun to fire from the rear cargo door.
This CH-47A Chinook model (includes 04 crews) is built at the scaled ratio of 1/35 (made by Trumpeter kit number 05104) by Probuiltmodel team.
