What is Project 75 of Indian Navy?

Indian Navy Project 75 aims to build 6 Scorpene Class attack submarine. These are diesel-electric attack submarines. The Scorpene Class submarines were built through ToT (transfer of technology) from a French Company DCNS at Mazagon Dock Ltd.

  • Under the Project 75, the first Scorpene submarine Kalvari was commissioned in 2017.
  • Second Scorpene Class Submarine that was commissioned in 2017 under the project was Scorpene Khanderi.

The Scorpene Class Submarine is a diesel-electric attack submarine that was jointly developed by DCNS and Spanish Navantia.

The beneficial feature of the Scorpene Class submarines is that they have an additional air-independent propulsion.

What is Air-Independent Propulsion?

Air-Independent Propulsion is a marine propulsion technology (MPT) that allows non-nuclear submarine to operate without accessing surface oxygen (or atmospheric oxygen).
