INS Karanj, the third submarine of the Calvary class being made in India, is expected to join the Navy in four to five months. Karanja was sent for sea trials in 2018 and according to sources these tests have been successful. The fourth submarine of the same class, INS Vela, will also join the Navy by the end of next year.
The first two submarines of the Kalvari class, Kalvari and Khanderi, have already joined the Navy. A total of 6 submarines of Kalvari class are being manufactured at Mazgaon Dock Limited, Mumbai. These submarines can stay in the sea for 50 days and can travel up to 12000 km at a time. It has 8 officers and 35 naval personnel and can dive up to 350 meters under the sea.
Submarines of the Kalvari class can move at 37 kmph under the sea. These include torpedoes to destroy a submarine inside the sea or a ship on the ocean surface. Apart from this, they can also lay landmines in the sea.
The Indian Navy had made a major plan in 1997 to make Submarine fleet stronger. Under this, there was a plan to make new 24 submarines by 2024, but this plan is still running behind schedule. Kalvari has joined the Navy in 2017 as the first submarine under the class ie Project 75. The project is expected to be completed by 2022.
Project 75 (India) of a more modern submarine equipped with air independent propulsion is expected to start soon. Tender for this project is coming out soon. Apart from these 12 submarines, India has plans to make 12 nuclear submarines.
Currently, the Indian Navy has 9 Indus Class, 3 in Shishumar class, 2 in Kalvari class and one nuclear submarine INS Chakra i.e. 14 submarines in total. Apart from these, there are two submarines of the Arihant class ie INS Arihant and INS Arighat which are nuclear ballistic submarines. Apart from nuclear submarine, all submarines of the Indian Navy are diesel-electric and due to lack of air independent propulsion, they have to surface every one or two days.
