The Bell UH-1Y Venom (also called Super Huey) is a twin-engine, medium-sized utility helicopter built by Bell Helicopter under the H-1 upgrade program of the United States Marine Corps. One of the latest members of the numerous Huey family, the UH-1Y is also called "Yankee", based on the NATO phonetic alphabet pronunciation of its variant letter. The UH-1Y was to have been remanufactured from UH-1Ns, but in 2005, it was approved for the aircraft to be built as new. After entering service in 2008, the UH-1Y replaced the USMC's aging fleet of UH-1N Twin Huey light utility helicopters, first introduced in the early 1970s. In 2008 it entered full-rate production, with deliveries to the Marines completed in 2018.
