A reversing trendįor decades, the number of nuclear weapons worldwide has been decreasing steadily. There was a slight reduction in the total number of nuclear warheads to an estimated 12,705 worldwide, this number will probably grow again in the course of the coming decade, the report said. Their useable military stockpiles remained relatively stable and within the limits set by a nuclear arms reduction treaty, SIPRI said. In 2021, the number of nuclear warheads in both countries declined further, but this was mainly due to the dismantling of discarded warheads, which the military had already abandoned years ago. Russia with 5,977 warheads and the US, with 5,428, together still possess about 90 percent of all nuclear warheads in the world, according to the report. “There are clear indications that the reductions that have characterised global nuclear arsenals since the end of the Cold War have ended,” said Hans Kristensen, associate senior fellow with SIPRI’s Weapons of Mass Destruction Programme and director of the Nuclear Information Project at the Federation of American Scientists (FAS). In its annual report published on Monday ( PDF), the Stockholm International Peace Research (SIPRI) said on Monday that all nine nuclear-armed countries are increasing or upgrading their arsenals.

The global stockpile of nuclear weapons is expected to rise in coming years for the first time since the Cold War due to global tensions, a leading arms watchdog has said.
