M65 Recoiless Nuclear Rifle

The M-28 or M-29 Davy Crockett Weapon System(s) was a tactical nuclear recoilless gun for firing the M388 nuclear projectile that was deployed by the United States during the Cold War. Named after American soldier, congressman, and folk hero Davy Crockett, it was one of the smallest nuclear weapon systems ever built.

The Davy Crockett was developed in the late 1950s for use against Soviet troops had war broken out in Europe. Small teams of the Atomic Battle Group (charged with operating the device) would be stationed every few kilometers to guard against Soviet attack, using the power of their nuclear artillery to kill or incapacitate advancing troop formations and irradiate the area so that it was uninhabitable for up to 48 hours, long enough to mobilize NATO forces.
The M-388 round used a version of the W54 warhead, a very small sub-kiloton fission device. The Mk-54 weighed about 51 lb (23 kg), with a selectable yield equivalent to 10 or 20 tons of TNT (very close to the minimum practical size and yield for a fission warhead). The complete round weighed 76 lb (34.5 kg). It was 31 in. (78.7 cm) long with a diameter of 11 in. (28 cm) at its widest point; a subcaliber piston at the back of the shell was inserted into the launcher's barrel for firing.[1] The "piston" was considered a spigot prior to the discharge of the propellant cartridge in the recoilless gun chamber of the Davy Crockett. The M388 atomic projectile was mounted on the barrel-inserted spigot via bayonet slots. Once the propellant was discharged the spigot became the launching piston for the M388 atomic projectile. The nuclear yield is hinted at in FM 9-11: Operation and Employment of the Davy Crockett Battlefield Missile, XM-28/29 (June 1963).
The M-388 could be launched from either of two launchers known as the Davy Crockett Weapon System(s): the 4-inch (102 mm) M28, with a range of about 1.25 mi (2 km), or the 6.1-in (155 mm) M29, with a range of 2.5 mi (4 km). Both weapons used the same projectile, and could be mounted on a tripod launcher or carried by truck or armored personnel carrier. They were operated by a three-man crew.[2]

Both recoilless guns proved to have poor accuracy in testing, so the shell's greatest effect would have been its extreme radiation hazard. Even at a low yield setting, the M-388 would produce an almost instantly lethal radiation dosage (in excess of 10,000 rem) within 500 feet (150 m), and a probably fatal dose (around 600 rem) within a quarter mile (400 m).[3]
The warhead was tested on July 7, 1962 in the Little Feller II weapons effects test shot, and again in an actual firing of the Davy Crockett from distance of 1.7 miles (2.72 km) in the Little Feller I test shot on July 17. This was the last atmospheric test detonation at the Nevada Test Site.
Production of the Davy Crockett began in 1956, with a total of 2,100 being made. The weapon was tested between 1962 and 1968 at the Pohakuloa Training Area on Hawaii island, with 714 M101 spotter rounds (not live warheads) that contained depleted uranium.[4][5] The weapon was deployed with U.S. Army forces from 1961 to 1971. It was inactivated from US Army Europe (in West Germany) in 1967.
Versions of the W54 warhead were also used in the Special Atomic Demolition Munition project and the AIM-26A Falcon.
The 55th and 56th Infantry Platoons, attached to the Division Artillery, of the US 82nd Airborne Division, were the last units equipped with the M-29, Davy Crockett weapons system. These two units were parachute deployed and the unit with its 1/2 ton truck per section (3 per Platoon) were fully air droppable. The units were deactivated in mid 1968.
