Annotated photograph of a training-dummy version of the M388 nuclear round [14] Stowage of the Davy Crockett weapon system in an M113 carrier. Projectile, Atomic, Supercaliber 279mm XM388 for the Davy Crockett contained a W54 Mod 2 nuclear warhead. It was a very compact pure fission device weighing 50.9 pounds (23.1 kg) and when packaged in the ...
Interest in a lightweight, low-yield weapon for the Falcon and Davy Crockett began in 1958. [2] The weapon was initially developed by the University of California Radiation Laboratory at Livermore under the XW-51 designation, [1] but in January 1959 the development of the weapon was transferred to Los Alamos National Laboratory and redesignated the XW-54.
In Little Feller II (July 7), the warhead was suspended only three feet above the ground and had a yield equivalent to 22 tons of TNT (92 GJ). In Little Feller I (July 17), the warhead was launched as a Davy Crockett device from a stationary 155 millimeter launcher and set to detonate between 20–40 feet (6.1–12.2 m) above the ground around ...
U.S. officials view a W54 nuclear warhead (with a 10- or 20-ton explosive yield) as used on the Davy Crockett recoilless gun, one of the smallest nuclear weapons ever made.
The chief milestone of Operation Sunbeam was that it was the last nuclear test series on the Nevada Test Site conducted in the atmosphere by the United States. Since Operation Sunbeam , specifically the Little Feller 1 test of the Davy Crockett, all US nuclear tests on the Test Site have been carried out underground in accordance with the ...
The development of the Davy Crockett nuclear device, an atomic weapon with a sub-kiloton energy yield that can be transported on the back of a jeep, served as a precursor to the eventual final product foreseen by the military, the Mk-54 SADM. The Davy Crocket's lightweight Mark-54 composition was encouraging to the further production and ...
The lightest nuclear warhead ever acknowledged to have been manufactured by the U.S. is the W54, which was used in both the Davy Crockett 120 mm recoilless rifle-launched warhead and the backpack-carried version called the Mk-54 SADM (Special Atomic Demolition Munition). The bare warhead package was an 11 by 16 inches (280 by 410 mm) cylinder ...
Test of small tactical warheads, including the man-portable "Davy Crockett". Last atmospheric test series. The Army's part of Sunbeam was Operation Ivy Flats. Dominic: 1962–1963 31: 31: 31: 2 to 9,960 34,640 "Frigate Bird" was the only operational test of a missile "mated" with a live warhead.
