India is taking a crucial step for its Rs 1.2 lakh crore project to produce future nuclear-powered submarines, with top levels of the government processing clearances for the detailed design phase.
The plan to build six advanced attack submarines — to be nuclear powered but armed with conventional missiles and torpedoes — is being monitored closely and the first of the boats could roll out in a decade if things go as per plan.

The initial design phase for the new boats has progressed successfully and more resources will now be deployed to move to the more complex detailed design and construction — to be undertaken by the Directorate of Naval Design (Submarine Design Group) with assistance from the Defence Research and Development Organisation (DRDO).

The timing of the critical clearances coincides with the pace of current work at the Ship Building Centre (SBC) in Visakhapatnam, where the Arihant class of nucleararmed submarines are being built. Major structural work on the fourth of the class is nearing completion and the centre would be able to take on work for the next generation of vessels as early as next year, if need be. Though this is unlikely as the developmental phase will take longer.

Sources said the second of the Arihant class — the slightly bigger and better-armed INS Arighat — is expected to be commissioned this year, adding teeth to India’s nuclear deterrence. Two follow-on boats after that are likely to enter service before 2024.

This would leave SBC with adequate space and resources to commence building the next generation of nuclear-attack submarines. While the Arihant project took over two decades to fructify, the next generation submarines are likely to progress at half the given time as adequate experience is now available, both in terms of design and construction of nuclear submarines.

Work on the submarine project gained pace last year with a defence public sector unit working on a special metal alloy for the hull and testing of a scale model as part of the design process. The plan to build six nuclear-powered attack submarines (SSNs) kicked off in 2015 when the NDA government gave a go ahead to a long-pending project for the Indian Navy.

DRDO's 100 kW Gas Dynamic Laser System... It is deployed on the same type of platform that SDSC SHAR's multi-object tracking radar does

+Primarily 2 types of system by the DRDO's Laser Science and Technology Centre (LASTEC). Gas Dynamic Laser Chemical Oxygen Iodine Lasers A gas-dynamic laser takes a hot, high-pressure mixture of gases (usually C02, N2, and H20 or He) and expands this mixture very rapidly.
