Project 75: fifth Kalvari class attack submarine delivered to indian navy

Subject :Defence

The fifth Scorpène submarine, Vagir of Project – 75 Kalvari Class submarines has been delivered to the Indian Navy by Mazagon Dock Shipbuilders Limited (MDL) Mumbai.

INS Vagir:

It is having “superior stealth features” like advanced acoustic absorption techniques.
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 the 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 Kalvariwas commissioned in December 2017, the second submarine INS Khanderiin September 2019, third one INS Karanj in March 2021 and the fourth one INS Vela joined service in November 2021.

About the Project 75:

This project envisages the indigenous construction of submarines equipped with a state-of-the-art Air Independent Propulsion system at an estimated cost of Rs. 43,000 crores.
Project 75 (I), approved in 2007, is part of the Indian Navy’s 30-year Plan for indigenous submarine construction.
It will be the first under the strategic partnership model which was promulgated in 2017 to boost indigenous defence manufacturing.
The strategic partnership model allows domestic defence manufacturers to join hands with leading foreign defence majors to produce high-end military platforms to reduce import dependence.
Acquisitions under the Strategic Partnership model refer to the participation of private Indian firms along with foreign OEM (Original Equipment Manufacturers) in ‘Make in India’ in defence.

About 30-year Submarine Plan:

The Cabinet Committee on Security, in June 1999, had approved a 30-year submarine-building plan which included the construction of 24 conventional submarines indigenously by 2030.
- P75I succeeded the P75 under which six diesel-electric attack submarines of the Kalvari class, based on the Scorpene class, were being built at MDL (Mazagon Dock Limited) – the six submarines under the project are: INS Kalavari, INS Khanderi, INS Kharanj, INS Vela, INS Vagir and INS Vagsheer.
- The fifth Diesel-electric attack submarine INS Vagir is commissioned.
Of the total 24 submarines to be built in India, six will be nuclear-powered.
India has only one nuclear submarine, INS Arihant, at the moment.
The INS Arighat, also a nuclear-powered ballistic missile submarine, is to be commissioned soon.
INS Chakra, a nuclear submarine, which is taken on lease from Russia, is believed to be on its way back to the country of origin.
