393rd Bomb Squadron
military unit
The 393rd Bomb Squadron is part of the 509th Bomb Wing at Whiteman Air Force Base, Missouri. It operates Northrop Grumman B-2 Spirit nuclear-capable strategic bomber aircraft.
The squadron was first organized in March 1944 as the 393rd Bombardment Squadron. In November 1944, the squadron transferred to the 509th Composite Group and began training for the delivery of nuclear weapons. In May 1945, it deployed to the Mariana Islands, where it became the only unit to use nuclear weapons in combat, when its aircraft dropped atomic bombs on Hiroshima and Nagasaki on 6 August 1945 and 9 August 1945. After V-J Day, the squadron returned to the United States, and was stationed at Roswell Army Air Field, New Mexico.
During the early years of the Cold War, the squadron was involved in Operation Crossroads, nuclear weapons testing on Bikini Atoll, and has continued to operate nuclear-capable aircraft since then. At Roswell, the squadron upgraded to Boeing B-50 Superfortresses and later, to jet powered Boeing B-47 Stratojets. In 1958, the squadron and its B-47s moved to Pease Air Force Base, New Hampshire. At Pease, it replaced its B-47s with Boeing B-52 Stratofortresses in 1966, and in 1970, became one of only two wings in Strategic Air Command to equip with the General Dynamics FB-111.
This brief starts where responsible research should: with the source description of “393rd Bomb Squadron” as military unit. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as military unit. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q4636081. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1944, 1945, 1958 and 1966.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
