Suitcase nuclear device

A suitcase nuclear device (also suitcase nuke, suitcase bomb, backpack nuke, snuke, mini-nuke, and pocket nuke) is a tactical nuclear weapon that is portable enough that it could use a suitcase as its delivery method.

During the 1950s and 1960s both the United States and the Soviet Union developed nuclear weapons small enough to be portable in specially designed backpacks.

Neither the United States nor the Soviet Union have ever made public the existence or development of weapons small enough to fit into a normal-sized suitcase or briefcase. The W48 however, does fit the criteria of small, easily disguised, and portable. Its explosive yield was extremely small for a nuclear weapon.

In the mid-1970s, debate shifted from the possibility of developing such a device for the military to concerns over its possible use in nuclear terrorism. The concept became a staple of the spy thriller genre in the later Cold War era.
