ICBM RV Yield [kt] (Warhead Type) Number of RVs Throw Weight [kg] RV Weight [kg]
MX/Peacekeeper 300-335 (W87) 10 3,950 200
Minuteman III 335 (W78);

170 (W62)

Sources: John R. Harvey and Stefan Michalowski, "Nuclear Weapons Safety: The Case of Trident," Science & Global Security, Volume 4, Issue 3 (1994), p. 288, in which they use throw-weight values from teh START Memorandum of Understanding to calculate RV weight by assuming that the bus that carries the RVs is about one half the throw weight. Some warhead yield values are from Rovert S. Norris and William M. Arkin, "U.S. Strategic Nuclear Forces, End of 1997," The Bulletin of the Atomic Scientists, January/February 1998, p. 71.
