About Matsya 6000

  • The National Institute of Ocean Technology (NIOT) in Chennai created the manned submersible vehicle.
  • It was created as part of the Samudrayaan program to help humanity explore mineral resources in the deep ocean.
  • It would make India one of just six countries (the United States, Russia, Japan, France, and China) to have piloted a crewed undersea expedition deeper than 5,000 meters.

Mission Objectives

  • Its goals will be to investigate chemosynthetic biodiversity in hydrothermal vents and low-temperature methane seeps in the ocean.
  • It will also promote ocean literacy and tourism.


  • It is meant to function in the deep water for 12 hours, but it can also run for up to 96 hours in an emergency, with all the necessary human safety procedures.
  • It is made of an 80mm thick titanium alloy and can withstand pressures 600 times greater than at sea level.
  • It is powered solely by gravity, water, and lithium-ion batteries.
  • The ultra-short baseline acoustic positioning system (USBL) will also be included. This allows the mothership carrying the transponder to send information and the submersible to respond, informing the mothership of the submersible's location.
  • This is a flotation device that will rise to the surface of the water, assisting in the recovery of the submersible even if it is unable to resurface.

Facts about the Samudrayaan Mission:

  • It is India's first manned deep-sea exploration mission.
  • It is intended to explore deep ocean resources as well as conduct biodiversity surveys.
  • Because the submersible is only used for exploration, the mission will have little impact on the environment.
  • The project is part of the wider Deep Ocean Mission, which supports the Blue Economy strategy of the Central Government.
  • The Ministry of Earth Sciences (MoES) is the nodal ministry in charge of putting this multi-institutional ambitious mission into action.
