Some will have one warhead, some three. At any given time, 99.4 percent of Minuteman IIIs not undergoing planned maintenance are ready for launch. During the Cold War, the difficulty of lifting multiple warheads with a single booster made it imperative to develop high “yield-to-weight” ratios, according to retired USAF Gen. Larry D. Welch, formerly the Chief of Staff and now head of the Institute for Defense Analyses in the Washington, D.C., area. This need, Welch went on, resulted in “exquisite” warhead designs containing “all kinds of esoteric, hard to handle materials.” Now, tests, and studies. According to Maj. Gen.
