Boeing Vertol CH-46E Sea Knight

The CH-46 Sea Knight was the standard medium sized cargo helicopter of the U.S. Marine Corps and the U.S. Navy from 1962 until 2015 when the last were retired. Design work on the Sea Knight began in 1960 for a U.S. Army contract. While the Army did not adopt the helicopter, it was taken up by the Navy and Marines in 1962. The CH-46 was widely used in every American combat operation from the Vietnam War to Iraq and Afghanistan providing troop and cargo transport. The CH-46 was continually upgraded and modified throughout its service life. The CH-46E was rebuilt from other versions of the helicopter with improved avionics and engines. Versions of the Sea Knight were exported to Canada, Sweden, Thailand, and Saudi Arabia. Additionally many were built by Kawasaki in Japan both for the Japanese military and for export.
