As of January 2023 the Russian Federation maintained a military stockpile of approximately 4489 nuclear warheads, a slight increase of around 12 warheads compared with the estimate for January 2022. About 2673 of these were strategic warheads, of which roughly 1674 were deployed on land-and sea-based ballistic missiles and at bomber bases. Russia also possessed approximately 1816 non-strategic (tactical) nuclear warheads. All of the non-strategic warheads are assessed to be at central storage sites. An additional 1400 retired warheads were awaiting dismantlement (100 fewer than the previous year’s estimate), giving a total estimated inventory of approximately 5889 warheads (see table 7.3).
