India  Launches Nuclear Submarine With ‘Vertical Launch System’

Boosting Indian Navy’s Firepower, DRDO Launches Nuclear Submarine With ‘Vertical Launch System’ Eurasian Times, By Shreya Mundhra January 2, 2022

Amid geopolitical tensions in the Indo-Pacific region, India has quietly launched its third Arihant-class nuclear-powered ballistic missile submarine — the S4 SSBN — at a secretive ship-building center in Visakhapatnam. The development was reported by Janes Defence Weekly, citing satellite imagery.

Arihant-Class Submarines

The Arihant-class, named after the country’s first nuclear-powered submarine — INS Arihant — is a class of Indian nuclear-powered ballistic missile submarines that are being built for the Indian Navy.

It was launched at the Indian Navy’s dockyard located in Visakhapatnam, the headquarters of Eastern Naval Command. The project, earlier called the advanced technology vessel (ATV), has been under development since 1998………

Russia’s Role In Indian Project

INS Arihant, which cost $2.9bn, was jointly developed by the Indian Navy, Bhabha Atomic Research Centre (BARC), and Defence Research and Development Organisation (DRDO) at the naval dockyard……………………….

Arihant And Arighat

INS Arihant was launched on July 26, 2009, by then-Prime Minister Manmohan Singh. Four years later, in August 2013, the submarine’s atomic reactor was activated. Three more years down the line, in August 2016, Prime Minister Narendra Modi inducted the submarine into the Navy………………………..

The Latest Addition — S4 SSBN

In its December 29 report, Janes noted that the S4 SSBN was launched on November 23 and had been ‘relocated’ close to the ‘fitting-out wharf’ that was previously occupied by INS Arighat.

According to Janes, satellite imagery had confirmed that the ship being talked about stood at 7,000-tonnes, “slightly larger” than the lead ship in the Arihant class, INS Arihant.

……. The magazine went on to infer that the satellite imagery indicated that the newly launched boats’ increased length “accommodates expansion of the submarine’s vertical launch system”. This system can support eight missile launch tubes, as planned.

This would enable the SSBN to carry eight K-4 SLBMs, or alternately, 24 K-15 SLBMs. The K-4 SLBM is currently under development.
