As of January 2021, the United States maintained a military stockpile of approximately 3800 nuclear warheads, roughly the same number as in January 2020. Approximately 1800 of these—consisting of about 1700 strategic and 100 non-strategic (or tactical) warheads—were deployed on aircraft, ballistic missiles and submarines. In addition, about 2000 warheads were held in reserve and around 1750 retired warheads were awaiting dismantlement (250 fewer than the estimate for 2020), giving a total inventory of approximately 5550 nuclear warheads (see table 10.2).
