The M-28 or M-29 Davy Crockett Weapon System was the tactical nuclear recoilless smoothbore gun for firing the M388 nuclear projectile armed with the W54 nuclear warhead that was deployed by the United States during the Cold War. It was the first and at the time was the utmost important project assigned to the United States Army Weapon Command in Rock Island, IL.[2] It was one of the smallest nuclear weapon systems ever built, with a yield between 10 and 20 tons TNT equivalent (40–80 gigajoules). It is named after American folk hero, soldier, and congressman Davy Crockett.

History
By the year 1950, there had been rapid developments made in the use of nuclear weapons after the detonation of "Little Boy" and "Fat Man" in 1945.[3] These developments paved the way for nuclear warheads to be created at a smaller size.[4]
By the 1950s, advances in nuclear weapons technology spurred on by the first detonation of the Soviet nuclear bomb in 1949 led to great reductions in the size of nuclear weapon. By 1957, the Atomic Energy Commission (AEC) declared that it had created a small fission warhead that could be deployed for frontline use by infantrymen.[disputed – discuss] AEC made Major General John H. Hinrichs the leader in turning the warhead into a weapon system which began at Picatinny Arsenal in New Jersey in January 1958.[4]
In August 1958, the Army started calling the BGADS as the Davy Crockett, after the American folk hero, who died at the battle of the Alamo in 1836.[5] After 4 years of testing at Forts Greeley and Wainwright in Alaska, and the Yuma Test Station in Arizona, the M28/M29 Davy Crockett entered service in May 1961.[4]
Davy Crockett Sections were assigned to United States Army Europe and Eighth United States Army armor and mechanized and non-mechanized infantry battalions. During alerts to the Inner German border in the Fulda Gap the Davy Crockett's accompanied their battalions. All V Corps (including 3rd Armored Division) combat maneuver battalions had preassigned positions in the Fulda Gap. These were known as GDP (General Defense Plan) positions. The Davy Crockett sections were included in these defensive deployment plans. In addition to the Davy Crocketts (e.g., assigned to the 3rd Armored Division), V Corps had nuclear artillery rounds and atomic demolition munitions, and these were also for use in the Fulda Gap. On the Korean peninsula, units assigned the Davy Crockett weapons primarily planned to use the passes that funneled armor as killing grounds, creating temporarily deadly radioactive zones roadblocked by destroyed tanks and other vehicles.
Production of the Davy Crockett began following the 15 August 1958 (at) Picatinny Arsenal approval of the design. There was approval for funding of 6,247 to be manufactured,[6] but a total of 2,100 were actually made. The weapon was tested between 1962 and 1968 at the Pohakuloa Training Area on Hawaiʻi island, with 714 M101 spotter rounds (not live warheads) that contained depleted uranium.[7][8] The weapon was deployed with US Army forces from 1961 to 1971.
