Built by Northrop Aircraft, the Snark was a large, winged, air-breathing missile with intercontinental range. The program began with much promise in 1946, but development proved to be far more difficult than either the contractor or the Air Force anticipated, and the first missiles did not become operational until 1960. By that time Snark's utility had been eclipsed by the Air Force's new intercontinental ballistic missiles. The Air Force withdrew its sole Snark squadron from active duty in June 1961.Specifications
