The B57 nuclear bomb was a tactical nuclear weapon developed by the United States during the Cold War.
Development began at the Los Alamos National Laboratory in 1960 to meet a requirement for a multi-purpose weapon, suitable for use as a nuclear depth charge or a nuclear bomb against ground targets. Entering production in 1963 as the Mk 57, the bomb was designed to be dropped from high-speed tactical aircraft. It had a streamlined casing to withstand supersonic flight. It was 3 m (9 ft 10 in) long, with a diameter of about 37.5 cm (14.75 in). Basic weight was approximately 227 kilograms (500 lbs).
Some versions of the B57 were equipped with a parachute retarder (a 3.8 m/12.5 ft diameter nylon/kevlar ribbon parachute) to slow the weapon's descent, allowing the aircraft to escape the blast (or to allow the weapon to survive impact with the ground in laydown mode) at altitudes as low as 15 m (50 ft). Various fuzing modes were available, including a hydrostatic fuze for use as a depth charge for anti-submarine use.
The B57 was produced in six versions (mods) with explosive yields ranging from 5 to 20 kilotons. Mod 0 was 5 kt, Mod 1 and Mod 2 were 10 kt, Mod 3 and Mod 4 were 15 kt, and...
