It is scheduled to be commissioned into service in January.

The fifth Scorpène-class conventional submarine,  Vagir, was delivered to the Navy by Mazagon Dock Shipbuilders Limited (MDL) Mumbai on December 20. It is scheduled to be commissioned into service next month, a Navy official said.

“It is a matter of great pride that Vagir has completed all major trials including the weapon and sensor trials in the shortest time in comparison to the earlier submarines,” the Navy said in a statement. A notable achievement is that this is the third submarine delivered to the Navy in a span of 24 months, it added.

Vagir was launched into water on November 12, 2020 and commenced sea trials on February 1, 2022.

The sixth and last of the Scorpène-class submarines,  Vagsheer, was launched into water in April 2022 and is expected to be delivered to the Navy by end 2023.

Six Scorpene submarines are being built under Project-75 by MDL under technology transfer from Naval Group of France under a $3.75 billion deal signed in October 2005. The project is about four years behind schedule.

The first submarine INS  Kalvari was commissioned in December 2017, second submarine INS  Khanderi in September 2019, third one INS  Karanj in March 2021 and the fourth one INS  Vela joined service in November 2021.

Parallelly, the tender to build six more advanced conventional submarines under Project-75I is in the Request For Proposal (RFP) stage but has suffered delays.

With delays in submarine induction, the SSKs – 209s (German HDWs) and EKMs (Russian Kilo’s), are being put through the Medium Refit Life Certification (MRLC) process which will give them additional life of 10 to 15 years.

The Navy currently has 15 conventional and one nuclear submarine in service. It includes seven Russian Kilo class submarines, four German HDW submarines, four Scorpene class submarines and the indigenous nuclear ballistic missile submarine INS  Arihant.

The Navy has drawn up plans to install Air Independent Propulsion (AIP) modules on all Scorpene submarines as they go for their refit beginning with INS Kalvari in the next couple of years to enhance their endurance. Development of an indigenous AIP module developed by the Defence Research and Development Organisation (DRDO) is in advanced stages.
