The W78 is an American thermonuclear warhead with an estimated yield of 335–350 kilotonnes of TNT (1,400–1,460 TJ), deployed on the LGM-30G Minuteman III intercontinental ballistic missile (ICBM) and housed in the Mark 12A reentry ...
The M28 or M29 Davy Crockett Weapon System was a 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 project assigned to the United States Army Weapon Command in Rock Island, Illinois. [3]
The W88 was designed at the Los Alamos National Laboratory in the 1970s. In 1999, the director of Los Alamos who had presided over its design described it as "the most advanced U.S. nuclear warhead". [4] As of 2021, the latest version is called the W88 ALT 370, [5] the first unit of which came into production on 1 July, 2021, after 11 years of ...
