warheads · 2026-01

North Korea is estimated to hold 60 nuclear warheads, about 0% of the world total, of which roughly 60 are in its military stockpile. All figures are open-source estimates as of 2026-01.

The only state to have joined the Non-Proliferation Treaty and then withdrawn, in 2003, and the only one to have tested nuclear weapons this century. Its plutonium came from a small gas-graphite reactor at Yongbyon based on a declassified British design; it later added uranium enrichment.
