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 ("neutron bomb") Mod 3 weapon entered service in 1981.[1] The last W70 warhead was dismantled in February 1996.[2]
