- It is India’s first unique manned ocean mission that aims to send men into the deep sea in a submersible vehicle for deep-ocean exploration and mining of rare minerals.
- It will send three persons in a manned submersible vehicle MATSYA 6000 to a depth of 6000 metres into the sea for deep underwater studies.
- Submarines go only about 200 metres.
- It is a part of the Rs 6000-crores Deep Ocean Mission.

- It will facilitate the MoES in conducting deep ocean exploration of resources such as gas hydrates, polymetallic manganese nodules, hydro-thermal sulfides, and cobalt crusts which are located at an approximate depth between 1000 and 5500 metres.
- Polymetallic nodules, also called manganese nodules, are mineral concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core.
