The Douglas AIR-2 Genie (previous designation MB-1 and also known as the blivet) was an unguided air-to-air rocket with a 1.5 kt W25 nuclear warhead. It was deployed by the United States Air Force (USAF 1957–1985) and Canada (Royal Canadian Air Force 1965–68, Air Command 1968–84) during the Cold War. Production ended in 1962 after over 3000 were made, with some related training and test derivatives being produced later.
