Nuclear-armed states increase deployed warheads, SIPRI reports

Nuclear-armed states placed additional warheads onto delivery systems during the past year, according to a report released Monday by the Stockholm International Peace Research Institute. SIPRI estimated the global total at 12,187 warheads, of which 9,745 remain in military stockpiles. The figure represents a marginal decrease from the previous year.

Deployment trends SIPRI director Karim Haggag told AFP that states are removing warheads from storage and placing them on nuclear-capable systems. He said this shift raises nuclear risks even as overall numbers fall. The institute stated that dismantlement rates are slowing while new deployments accelerate, a combination that could reverse the long-term decline in total arsenals.

Russia together hold roughly 83 percent of the world's nuclear warheads, each possessing more than 5,000. Both nations continue modernization programs that have encountered delays and cost increases. SIPRI estimated China holds 620 warheads and is expanding its arsenal faster than any other country.

India is believed to have increased its total slightly to 190 warheads. Pakistan's stockpile remained at 170 while it continued to produce fissile material. North Korea is estimated to possess about 60 warheads and is pursuing further expansion. Israel is assessed to hold approximately 90 warheads and is modernizing its forces.
