Context

The sixth and last of the French Scorpene-class submarines, INS Vagsheer, was launched into water at the Mazagon Docks in Mumbai.

Launch of INS Vagsheer

  • It was launched by Veena Ajay Kumar (wife of Union Defence Secretary), in keeping with the naval tradition of launch and naming by a woman.
  • The six submarines were being built under Project-75 by the Mazagon Docks under technology transfer from the Naval Group as part of a $3.75-billion deal signed in October 2005-
    • INS Kalvari was commissioned in December 2017
    • INS Khanderi in September 2019
    • INS Vagir in November 2020
    • INS Karanj in March 2021
    • INS Vela in November 2021
  • P 75 is one of two lines of submarines, the other being P75I, as part of a plan approved in 1999 for indigenous submarine construction with technology taken from overseas firms.

About ‘Vagsheer’

  • Vagsheer is named after the sand fish, a deep sea predator of the Indian Ocean.
  • The first submarine Vagsheer, from Russia, was commissioned into the Indian Navy on December 26, 1974, and was decommissioned on April 30, 1997.
  • The new Vagsheer will be officially named at the time of its commissioning.

Features

  • Vagsheer can take up to eight officers and 35 men.
  • It is 67.5 metres long and 12.3 metres high, with a beam measuring 6.2 metres Vagsheer can reach top speed of 20 knots when submerged and a top speed of 11 knots when it surfaces
  • It has four MTU 12V 396 SE84 diesel engines, 360 battery cells for power, and a silent Permanently Magnetised Propulsion Motor.
  • The hull, fin and hydroplanes are designed for minimum underwater resistance and all equipment inside the pressure hull is mounted on shock-absorbing cradles for enhanced stealth.

What is Project-75?

  • The Project 75I-class submarine is a follow-on of the Project 75 Kalvari-class submarine for the Indian Navy.
  • In the late 1990s, around the time of Kargil war, a three-decade plan took shape for indigenous construction of submarines.
  • It was known to have two separate series of submarine building lines – codenamed Project 75 and Project 75I — in collaboration with foreign entities.
  • Under this project, the Indian Navy intends to acquire six diesel-electric submarines, which will also feature advanced air-independent propulsion systems.
  • This is for enabling them to stay submerged for longer duration and substantially increase their operational range.
