Background of INS Vagir

The second INS Vagir is an iteration of a submarine purchased from Russia on December 3, 1973. It was decommissioned on June 7, 2001.

Vagir is named after the Sand fish, a deep sea predator found in the Indian Ocean.

As stated earlier, INS Vagir is a Kalvari class submarine. The Kalvari class is a type of diesel-electric attack submarine based on the  Scorpène-class. These class of submarines derive their name from the first submarine inducted in the Indian Navy, INS Kalvari, that was launched in October 2015.

INS Vagir is a part of Project 75. Project 75 is an indigenous project for the construction of 6 attack submarines for the Indian navy.

The $3.75 bn project is supported by the Department of Defence Production, which in turn is part of the Ministry of Defence. The Naval Group of France is lending its technological expertise to the project.

The status of the remaining submarines is as follows:

  • INS Kalvari and INS Khanderi have been commissioned into the Indian Navy
  • INS Karanj finished its sea trials and it was commissioned into the ranks of the Indian Navy on March 10, 2021
  • INS Vela is undergoing sea trials and is expected to be commissioned by the end of 2021
  • INS Vagsheer is currently under construction.

Importance of Submarines for Indian Navy

At present India operates one submarine each in the nuclear-driven classes of Chakra and Arihand in addition to 14 submarines belonging to the Diesel-Electric category, like the Shishumar and Sindhughosh, most of which are ageing.

Both nuclear powered and diesel-electric submarines have their roles in Carrier Battle Groups. Carrier Battle Groups are naval formations of ships and submarines with the Aircraft Carriers playing the central role.

Submarines like the INS Vagir are crucial for India’s strategic deterrence and in protecting its sovereignty in the Indian Ocean Region. In the wake of the “string of pearls” doctrine followed aggressively by China, the submarines of Project 75 will prove to be a crucial asset.
