The B57

nuclear bomb was a tactical nuclear weapon developed by the United States during the Cold War

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

(500 lbs).

Some versions of the B57 were equipped with a parachute retarder (a 3.8 m/12.5 ft diameter

hydrostatic fuze for use as a depth charge for anti-submarine

The B57 was produced in six versions (mods) with explosive yields ranging from 5 to 20

U.S. Navy, replaced the Mk 101 Lulu
and had selectable yield up to 10 kt.

The B57 used the

Tsetse primary
design for its core design, shared with several other mid- and late-1950s designs.

The B57 was produced from 1963 to 1967. After 1968, the weapon became known as the B57 rather than the Mk 57. 3,100 weapons were built, the last of which was retired in June 1993.

The B57 could be deployed by most U.S.

CF-104s in Germany, and the Royal Air Force's Nimrod from RAF St Mawgan and RAF Kinloss in the United Kingdom and Malta
in the Mediterranean.
