- The Project 75 India-class submarines are a planned class of diesel-electric submarines.

Background
- In 1999, the Cabinet Committee on Security approved a 30-year plan for the Indian Navy to indigenously build and induct 24 submarines by 2030.
- In the first phase, two lines of production were to be established — the first, P-75; the second, P-75I.
- Each line was to produce six submarines.
- The first submarine under the P 75 project was commissioned in 2017.
- The final submarine, Vagsheer, was launched in April 2022.
