Bell Huey family

The Bell Huey family of helicopters includes a wide range of civil and military aircraft produced since 1956 by Bell Helicopter. This H-1 family of aircraft includes the utility UH-1 Iroquois and the derivative AH-1 Cobra attack helicopter series and ranges from the XH-40 prototype, first flown in October 1956, to the 21st-century UH-1Y Venom and AH-1Z Viper. Although not flown in military service in the USA, the Bell 412 served in Canada and Japan and, like the UH-1Y, is a twin engine four rotor design based on the Bell 212.
