Weapons

India has worked to develop an autonomous military industry since independence was gained. Until now, success has been challenging, and despite design efforts in many areas, most resulting weapons have not completely met domestic requirements, nor become export successes india possesses nuclear weapons and maintains short- and intermediate-range ballistic missiles, nuclear-capable aircraft, surface ships, and submarines under development as possible delivery systems and platforms. Although it lacks an operational ballistic missile submarine, India has ambitions of possessing a nuclear triad in the near future when INS Arihant the lead ship of India's Arihant class ofnuclear-powered submarines formally joins the Indian Navy in 2012 after undergoing extensive sea-trials. Though India has not made any official statements about the size of its nuclear arsenal, recent estimates suggest that India has between 80 and 100 nuclear weapons,^[4]consistent with earlier estimates that it had produced enough weapons-grade plutonium for up to 75-110 nuclear weapons.^[5] Production of weapons-grade plutonium is believed to be taking place at the Bhabha Atomic Research Centre, which is home to the CIRUS reactor, acquired from Canada and shut down in 2010, to the indigenous Dhruva reactor, and to a plutonium separation facility.

India is not a signatory to the 1968 Nuclear Non-Proliferation Treaty (NPT), which India argues entrenches the status quo of the existing nuclear weapons states whilst preventing general nuclear disarmament.^[6] India tested a nuclear device in 1974 (code-named "Smiling Buddha"), which it called a "peaceful nuclear explosion." The test used plutonium produced in the Canadian-supplied CIRUS reactor, and raised concerns that nuclear technology supplied for peaceful purposes could be diverted to weapons purposes. This also stimulated the early work of the Nuclear Suppliers Group.^[7] India performed further nuclear tests in 1998 (code-named "Operation Shakti")
