As of January 2024 the United States maintained a military stockpile of approximately 3708 nuclear warheads, the same number as the previous year. Approximately 1770 of these—consisting of about 1670 strategic and roughly 100 non-strategic (tactical) warheads—were deployed on ballistic missiles and at bomber bases. In addition, about 1938 warheads were held in reserve and around 1336 retired warheads were awaiting dismantlement (200 fewer than the previous year’s estimate), giving a total inventory of approximately 5044 nuclear warheads (see table 7.2, end of section).
