The 4925th Test Group is a discontinued United States Air Force unit. It was last assigned to the 4901st Support Wing (Atomic), at Kirtland Air Force Base, New Mexico, where it was discontinued on 31 August 1961. Known as "The Megaton Blasters", the 4925th was responsible for the development flight testing of all USAF nuclear weapon delivery systems including conducting live test drops from 1951 though 1956. Following 1956 the group focused on operational methods and equipment for delivering nuclear weapons. It was discontinued when Air Force Systems Command replaced Air Research and Development Command and components of its mission were distributed among other units.
