Indian Naval Ship (INS) Vagir is the fifth among the six Kalvari-class submarines being constructed by the public sector shipbuilder Mazagon Dock Ltd (MDL) in Mumbai.
The other vessels in the class are INS Kalvari, INS Khanderi, INS Karanj, INS Vela and INS Vagsheer.
Of these Kalvari and Khanderi have been commissioned in 2017 and 2019, Vela and Karanj and undergoing sea trials, Vagir has now been launched and Vagsheer is under construction.
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.
The design of Kalvari class of submarines is based on Scorpene class of submarines designed and developed by French defence major Naval Group formerly DCNS and Spanish state owned entity Navantia.
This class of submarines have Diesel Electric transmission systems and these are primarily attack submarines or ‘hunter-killer’ type which means they are designed to target and sink adversary naval vessels.
These submarines are around 220 feet long and have a height of 40 feet. It can reach the highest speeds of 11 knots when surfaced and 20 knots when submerged.
The modern variants of the Scorpence class of submarines have what is called the Air Independent Propulsion (AIP) which enables non-nuclear submarines to operate for a long time without access to surface oxygen.
