India now possesses 180 nuclear warheads, up from 172 in 2024, while China has surged ahead to 600, adding 100 in a year. SIPRI warns of global arsenal growth and rising nuclear conflict risks.
New Delhi: India has slightly increased its nuclear warheads to 180 in 2025 from 172 in 2024 while the China’s arsenal has been growing faster than any other country and has currently expanded to 600, a rise of 100 warheads in 2025, the Stockholm International Peace Research Institute (SIPRI) said in its new yearbook which was released on Monday.
However, Pakistan’s nuclear arsenal stands still at 170. There has been no change observed.
Stockholm International Peace Research Institute's report
In its yearbook “state of armaments, disarmament and international security”, the SIPRI said: “India’s new ‘canisterized’ missiles, which can be transported with mated warheads, may be capable of carrying nuclear warheads during peacetime, and possibly even multiple warheads on each missile, once they become operational.”
