The Democratic People’s Republic of Korea (DPRK, or North Korea) maintains an active but highly opaque nuclear weapon programme. SIPRI estimates that, as of January 2023, North Korea possessed around 30 nuclear weapons (see table 7.9, end of section), but that it probably possessed sufficient fissile material for an approximate total of 50–70 nuclear devices, depending on warhead design.
