The Davy Crockett consisted of an XM-388 projectile launched from either a 120-millimeter or 155-millimeter recoilless rifle. The 120mm weapon had a maximum range of 1.24 miles and 2.49 miles with the 155 millimeter RR. The XM-388 projectiles weighed 76 pounds, was 30 inches long and measured 11 inches in diameter. This was the smallest and lightest fission bomb ever deployed by the United States, with a variable explosive yield of 0.01 kilotons "equivalent to 10 tons of TNT". The Davy Crockett was deployed with U.S. Army forces from 1961 to 1971. Between 1956 and 1963, 2,100 were produced.
