Under Project 75-India, the Navy wants to build six conventional diesel-electric submarines which would be almost 50 per cent bigger than the under-construction Scorpene class submarines being built at the Mazagon Dockyards Limited in Mumbai. The submarines should have the ability to carry and launch 18 heavyweight torpedoes in the sea. For the Indian Navy, the Project 75I-class submarine is a follow-on of the Project 75 Kalvari-class submarines. The submarines will be equipped with heavy-duty firepower as it wants the boats to have at least 12 Land Attack Cruise Missiles (LACM) along with Anti-Ship cruise missiles (ASCM).
