The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War.It is a low-to-intermediate yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design.
The B61 bomb was developed by Los Alamos Scientific Laboratory (LASL; now Los Alamos National Laboratory) starting in 1960.The intent was to develop an aircraft bomb which was high yield (over 100 kilotons) and yet was small enough and had low enough drag to carry under the wing of a fighter or fighter-bomber type aircraft.

The strategic weapons included 1,490 ICBM warheads, 2,736 submarine-launched ballistic missile warheads, 1,660 bomber weapons such as strategic B61 and B83 gravity bombs, AGM-86 ALCM and several hundred spare warheads. The tactical weapons consist of 800 tactical B61 gravity bombs and 320 nuclear warheads for Tomahawk missiles.
Development continued, with weapons such as the nuclear B61, and conventional thermobaric weapons and GBU-28. One of the more effective housings, the GBU-28 used its large mass (4,700 lb or 2,130 kg) and casing (constructed from barrels of surplus 203 mm howitzers ) to penetrate 20 feet (6 metres) of concrete, and more than 100 feet (30 m) of ...

The first flight of Matador, model XSSM-A-1, occurred at the White Sands Missile Range on 20 January 1949. The first two production B-61 Matador missiles arrived at Eglin AFB, Florida, in September 1953, becoming operational, [6] and the missiles were under the control of the 6555th Guided Missile Squadron, for climatic testing, although instrumentation and pre-test check-outs kept the actual ...
A B61 nuclear bomb in various stages of assembly; the nuclear warhead is the bullet-shaped silver canister in the middle-left of the photograph. A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb.
