As of January 2019, the United States maintained a military stockpile of nearly 3800 nuclear warheads, roughly the same number as in January 2018.¹ The stockpile included approximately 1750 deployed nuclear warheads, consisting of about 1600 strategic and 150 non-strategic warheads. In addition, about 2050 warheads were held in reserve and around 2385 retired warheads were awaiting dismantlement, giving a total inventory of approximately 6185 nuclear warheads (see table 6.2).
