WHY IN NEWS PROJECT 75?
The Indian Navy is set to commission INS Vela, on November 25, 2021, which is the fourth stealth Scorpene-class submarine under Project 75 or Project 75 I.
What is Project-75?
- The Project 75I-class submarine is a follow-on of the Project 75 Kalvari-class submarine for the Indian Navy.
- 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.
ABOUT PROJECT 75 I
The Mazagon Dock Limited (MDL) is manufacturing six Scorpene submarines with technical assistance from the Naval Group of France.
DO YOU KNOW?
MDL is a defense public sector undertaking shipyard under the Ministry of Defence
Scorpene Class Submarine:
- The submarines in the Project-75 I Scorpene Class are powered by diesel-electric propulsion systems.
- Scorpene is one of the most sophisticated submarines, capable of undertaking multifarious missions including anti-surface ship warfare, anti-submarine warfare, intelligence gathering, mine laying, and area surveillance.
- The Scorpene class is the Navy’s first modern conventional submarine series in almost two decades since INS Sindhushastra, procured from Russia in July 2000.
Strategic importance of these submarines
- India currently operates one submarine each in nuclear-powered Classes of Chakra and Arihant and in addition to 14 submarines belonging to three classes of Diesel Electric category — Kalvari, Shishumar and Sindhughosh, some of which are ageing.
- The nuclear powered and diesel-electric submarines have their designated roles in the Carrier Battle Groups, which are formations of ships and submarines with Aircraft Carriers at the lead role.
- Currently, India has less number of submarines than what is required with some more of those from both types being at various stages of construction.
Back 2 Basics: Classes of Submarines in India
- In maritime terms, a class of ships is a group of vessels which have the same make, purpose and displacement.
- In the Navy and Coast Guard in India, the ships belonging to a particular class are named in a specific manner.
- Many times the names have the same first letters, prefixes, similar meanings or the names belong to a particular type of words for example names of cities, persons, mythological concepts, animals, rivers, mountains, weapons, etc.
- The class is generally named after the first vessel in the category. In some cases, a particular class of vessels takes their names from an earlier class of vessels which are now decommissioned.
- Like Kalvari – which means Tiger Shark, Vagir has been named after a Sand Fish, a predatory marine species.
- Khanderi has been named after an Island Fort built by Chhatrapati Shivaji, which played a key role in his Navy.
- Karanj has also been named after an Island located South of Mumbai.
Six submarine names are
- INS Kalavari
- INS Khanderi
- INS Kharanj.
- INS Vela
- INS Vagir
- INS Vagsheer
