The W70 was an American thermonuclear warhead.
W70 may also refer to:
A neutron bomb, officially defined as a type of enhanced radiation weapon (ERW), is a low-yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while minimizing the physical power of the blast itself. The neutron release generated by a nuclear fusion reaction is intentionally allowed to escape the weapon, rather than being absorbed by its other components. The neutron burst, which is used as the primary destructive action of the warhead, is able to penetrate enemy armor more effectively than a conventional warhead, thus making it more lethal as a tactical weapon.
W70 was a two-stage, thermonuclear warhead that was developed for the MGM-52 Lance missile by the United States. Designed by Lawrence Livermore National Laboratory, the Mod 1 and Mod 2 version of the weapon entered service in 1973, while the enhanced radiation Mod 3 weapon entered service in 1981. The last W70 warhead was dismantled in February 1996.
The MGM-52 Lance was a mobile field artillery tactical surface-to-surface missile system used to provide both nuclear and conventional fire support to the United States Army. The missile's warhead was developed at Lawrence Livermore National Laboratory. It was replaced by MGM-140 ATACMS, which was initially intended to likewise have a nuclear capability during the Cold War.
The W63 was the Lawrence Livermore Laboratory's entry into a brief competition between Livermore and Los Alamos to design a warhead for the Army's Lance tactical surface to surface missile.
The W64 nuclear warhead was the Los Alamos Laboratory's entry into a brief competition between Lawrence Livermore Laboratory and Los Alamos to design an "enhanced-radiation" nuclear warhead for the United States Army's MGM-52 Lance tactical surface-to-surface missile. In July 1964, both Livermore Labs and Los Alamos started developing competing warheads for the Lance. The Los Alamos design, the W64, was canceled in September 1964 in favor of Livermore's W63. In November 1966, the W63 was canceled in favor of the W70, the model that finally entered production.
