The W78 thermonuclear warhead is the warhead used on most of the United States LGM-30G Minuteman III intercontinental ballistic missiles (ICBMs), along with the MK-12A reentry vehicle which carried the warhead. Minuteman III's initially deployed with the older W62 warhead; the W78 was deployed starting in December 1979 onto 300 missiles, three warheads per missile. Declassified records indicate a total of 1,083 W78s were produced.
