Project-75 (India), simply referred to as the P-75(I) program, is a military acquisition initiative affiliated to India's Ministry of Defence (MoD), aimed at the planned procurement of diesel-electric submarines for the Indian Navy (IN).

Powered by a V-3420-19 24-cylinder engine rated at 2,600 hp (1,900 kW) driving co-axial contra-rotating propellers, the XP-75 flew for the first time on 17 November 1943. The second XP-75 flew shortly thereafter, with all six long-range XP-75s entering the test program by the spring 1944.

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 third submarine, INS Karanj, was commissioned in March 2021. Of the total 24 submarines to be built in India, six will be nuclear-powered.

2025年1月27日 · Project-75, the precursor to Project-75I, was initiated in 1997 with the aim of building two indigenous SSK (United States diesel-electric) submarines. The project was divided into two phases: Phase I and Phase II. Phase I involved the construction of some submarines at MDL under Project-75.

Project 75 is a programme by the Indian Navy that envisaged building six Scorpene-Class attack submarines. The Mazagon Dock Limited (MDL) is manufacturing six Scorpene submarines with technical assistance from the Naval Group of France. Three submarines INS Kalavari, INS Khanderi and INS Kharanj have been commissioned into the Indian Navy.
