The B83 nuclear weapon is a variable-yield gravity bomb developed by the United States in the late 1970s entering service in 1983. With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ) (75 times the yield of the atomic bomb Little Boy dropped on Hiroshima on 6 August 1945 which had a yield of 16 kilotonnes of TNT (67 TJ)) it is the most powerful nuclear free-fall weapon in the United States arsenal.
