  1. Gadget, MK-III plutonium implosion assembly mechanism, tested on 100 foot steel tower July 16, 1945 at Trinity Site, NM
  2. Little Boy, MK-I uranium gun assembly mechanism, dropped August 6, 1945 on Hiroshima
  3. Fatman, MK-III plutonium implosion assembly mechanism, dropped August 9, 1945 on Nagasaki
  4. unnamed, MK-III plutonium implosion assembly mechanism, arrived in San Francisco on August 18, 1945 (probably could have been dropped around August 25, 1945) but was returned to Los Alamos because Truman had ordered further atomic bombing stopped without his personal authorization.

Twenty more atomic bombs were scheduled for production and delivery before the end of 1945 and production could have continued at at least seven a month after that.
In fact production slowed rapidly after the end of the war (with no more demand for atomic bombs and to allow maintenance and repair of the Hanford reactors) and only five more had been produced by the end of Operation Crossroads in the summer of 1946 (which detonated two more MK-III plutonium implosion assembly mechanism bombs named Able and Baker).
