Article here. I can remember back in the Reagan era when you could drive a leftist into hysterical foaming rage just by mentioning this weapon.

The last of the Minuteman III missiles will receive their new motors by 2008. It costs about $5.2 million to replace the rockets on each missile. The new rocket motors, which have to comply with EPA (Environmental Protection Agency) rules, will have a shorter range than the original motors (which was classified, but thought to be nearly 10,000 kilometers, based on where the missiles were stationed and where likely Russian targets were.)

The Minuteman III guidance systems and control electronics, in the silo and launch center, are also being upgraded. The Minuteman III entered service in 1968, the Minuteman I did so in 1962, as the first solid fueled ICBM.

Finally, to comply with disarmament agreements, the Minuteman third stage, that contains three 440 pound nuclear weapons, will be replaced with a warhead containing one 600 pound nuclear weapon.

Did you know atomic missiles needed to comply with EPA regulations?
