The W87 is an American thermonuclear missile warhead. It was created for use on the MX or Peacekeeper ICBM, 50 of which, with up to 12 warheads per missile, were deployed during the 1986-2005 period. Starting in 2007, 200 of the W87 warheads from now-retired MX/Peacekeeper missiles will be retrofitted onto much older Minuteman III missiles, with only one warhead on each missile.
