The world's only nuclear artillery shell was fired once in 1953

In short: During the Cold War, superpowers raced to develop tactical nuclear weapons capable of hitting battlefield targets with conventional cannons. While many systems were built, only one nuclear artillery shell ever actually detonated in history—a 15-kiloton blast that proved the terrifying feasibility of

In 1953, the United States conducted a test at the Nevada Test Site codenamed Shot GRABLE. This event saw the detonation of a 280 mm (11 inch) shell containing a W9 fission warhead. The shell was fired from a massive, purpose-built artillery piece nicknamed "Atomic Annie" and exploded 160 m (525 ft) above the ground at a distance of 10,000 m (6.2 miles).

While the U.S. and the Soviet Union both pursued nuclear artillery, they eventually moved toward mobile tactical ballistic missiles. The Soviets initially tried purpose-built weapons like the 406 mm "Kondensator" gun and the 420 mm "Transformer" mortar in the late 1950s, but both were deemed unwieldy and obsolete. They eventually pivoted to firing nuclear munitions from standard 152 mm artillery, with the 3BV3 weapon being accepted in 1965.

The U.S. also experimented with various delivery methods, including the M-65 Atomic Cannon and the 16-inch Mark 7 gun on Iowa-class battleships. However, most production focused on smaller 155 mm shells like the W48, which yielded only 100 tons of TNT. By 1991, the U.S. The US independently retired its nuclear artillery shells in 1991, with Russia doing the same by 1992, as attention turned toward nuclear bunker buster munitions.

The development of these weapons highlights a specific era of 'tactical' nuclear strategy—aiming for battlefield use rather than strategic strikes on cities. While some NATO countries like Belgium and the UK hosted nuclear weapons, they did not control them directly; instead, they were held by embedded custodial units from the developing nations.
