Pakistan is estimated to possess about 100–120 nuclear weapons for delivery by aircraft and land-based missiles. It is widely believed that, in peacetime, Pakistan stores its nuclear warheads separate from their delivery vehicles. However, the Strategic Plans Division (SPD), which operates Pakistan’s nuclear forces, has never confirmed such arrangements.

Pakistan’s current warhead designs are believed to use highly enriched uranium (HEU). Pakistan continues to produce HEU for military purposes and its total stockpile was estimated at 2.7–3.5 tonnes in 2014. The enrichment takes place at the gas centrifuge facilities located at Kahuta and Gadwal in Punjab.
