WSJ: “The Pentagon said the U.S. had a total of 5,113 nuclear warheads in its stockpile as of Sept. 30, plus a few thousand more that had been retired but still needed to be dismantled. Between fiscal years 1994 and 2009, the U.S. dismantled 8,748 nuclear warheads. At its peak at the end of fiscal year 1967, the U.S. had 31,255 warheads, the Pentagon said. It was the first time the U.S. has disclosed those figures, which had been previously regarded as highly classified. A senior defense official said at a Pentagon briefing that the stockpile had been reduced by 75% since 1989 and roughly 84% since 1967.”
