An article titled ‘Indian nuclear forces 2017,’ written by experts
As per the article, India has produced around 600 kilograms of weapons-grade plutonium, which is sufficient for 150-200 nuclear warheads. However, out of these, only 120-130 weapons have actually been produced.
As per their estimates, New Delhi is operating seven nuclear-capable systems, including two aircraft, four land-based ballistic missiles, and one sea-based ballistic missile.
"At least four more systems are in development. The development program is in a dynamic phase, with long-range land- and sea-based missiles emerging for possible deployment within the next decade," the article said.
As per Kristensen and Norris, the two-stage, solid-fuel, rail-mobile Agni-2, the improvement variant of Agni-1, which can deliver a nuclear or conventional warhead more than 2,000 kilometres is probably targeted on western, central, and southern regions of China.
