India's nuclear arsenal is a joke.India has a modest nuclear arsenal. The emphasis is NOT on numbers but on survive-ability due to no first use policy.
However India has the materials available for more than 1000 nuclear devices. So many devices have not been made though. The actual number may be only around 100.
The type of weapons are similar to the ones tested last time. There may be improvements in design but these are minor.
India's focus is on missile development, specially missiles that are mobile (both road/rail) and can be fired at short notice. The focus of research remains reliability and accuracy of such missiles.
India will rely on geographic scattering of its weapons rather than hiding if a war comes. Entire north India will be used for firing.

May 11, 1998: Operation Shakti (type: implosion, 3 uranium and 2 plutonium devices, all underground). The Atomic Energy Commission (AEC) of India and the Defence Research and Development Organisation (DRDO) simultaneously conducted a test of three nuclear devices at the Indian Army Pokhran Test Range (IAPTR) on May 11, 1998. Two days later, on May 13, the AEC and DRDO carried out a test of two further nuclear devices, detonated simultaneously. During this operation, AEC India claimed to have tested a three-stage thermonuclear device (Teller-Ulam design), but the yield of the tests was significantly lower than that expected from thermonuclear devices. The yields remain questionable, at best, by Western and Indian scholars, estimated at 20kt-45kt.
