India possesses nuclear weapons and previously developed chemical weapons. Although India has not released any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 180 nuclear weapons. India has conducted nuclear weapons tests in a pair of series namely Pokhran I and Pokhran II.
India is a member of three multilateral export control regimes — the Missile Technology Control Regime, Wassenaar Arrangement and Australia Group. It has signed and ratified the Biological Weapons Convention and the Chemical Weapons Convention. India is also a subscribing state to the Hague Code of Conduct. India has signed neither the Comprehensive Nuclear-Test-Ban Treaty nor the Nuclear Non-Proliferation Treaty, considering both to be flawed and discriminatory. India previously possessed chemical weapons, but voluntarily destroyed its entire stockpile in 2009 — one of the seven countries to meet the OPCW extended deadline.
India maintains a "no first use" nuclear policy and has developed a nuclear triad capability as a part of its "credible minimum deterrence" doctrine. Its no first use is qualified in that while India states it generally will not use nuclear weapons first, it may do so in the event of "a major attack against India, or Indian forces anywhere, by biological or chemical weapons."
