  • It aims to explore the deep ocean for resources and develop deep-sea technologies for sustainable use of ocean resources.
  • Promote tourism and ocean literacy
  • It aims to develop “a self-propelled manned submersible to carry three human beings to a water depth of 6,000 meters in the ocean with a suite of scientific sensors and tools for deep ocean exploration.
  • It seeks to carry out deep ocean exploration of non-living resources such as polymetallic manganese nodules, gas hydrates, hydro-thermal sulfides, and cobalt crusts, located at a depth between 1000 and 5500 meters.
  • Investigate chemosynthetic biodiversity in hydrothermal vents and methane seeps.

  • It is a three-person submersible capable of reaching 6,000 meters underwater.
  • It has been developed by Chennai’s National Institute of Ocean Technology (NIOT).
  • The Matsya 6000 is constructed with an 80mm-thick titanium alloy to withstand high underwater pressures.
  • This vehicle can operate continuously for 12 to 16 hours with a 96-hour oxygen supply (in case of emergency).
  • USBL :
    • The Indian submersible vehicle is equipped with redundancy systems for safety and an ultra-short baseline acoustic positioning system (USBL) for tracking.
    • It is used to track subsea targets such as ROVs/AUVs or divers. It can also be used as a means of position referencing for surface vessels Dynamic Positioning (DP).
  • Reliability  :
    • This special vehicle relies only on gravity, water, and lithium-ion batteries for power.
  • Floatation devices :
    • This is a flotation device that will rise to the top of the ocean — thus helping to find the submersible even in case it cannot resurface.

Project Timeline :

  • Trials for Matsya 6000 are likely to occur in early 2024 in the Bay of Bengal.
  • The Samudrayaan project, part of India’s Rs 4,077-crore Deep Ocean Mission, India’s initiative to play a leadership role in sustainable ocean exploration and resource development aims for completion by 2026.

Blue Economic Policy:       

Blue economy refers to the sustainable use of marine resources for exploration, economic growth, improved livelihoods, and transport while preserving the health of marine and coastal ecosystems.

In India, the blue economy encompasses a wide range of sectors, including shipping, tourism, fisheries, and offshore oil and gas exploration. The blue economy of India is a subdivision of the national economy that includes the complete ocean resources system as well as human-made economic infrastructure in the country’s legal jurisdiction marine, maritime, and onshore coastal zones.

India’s Blue Economy concept is multi-faceted and plays an important role in the country’s economic growth because of its enormous maritime interests. India’s blue economy accounts for roughly 4% of the GDP and is estimated to increase once the mechanism is improved. The sector has stood strong despite the challenges caused by the COVID-19 pandemic and has recorded exports worth Rs. 56,200 (US$ 7.2 billion) between April 2021 and February 2022.

India is going to uncover the secrets of the deep ocean supporting the central government’s Blue Economic Policy.

Ministry of Earth Sciences

Ministry of Earth Science (MoES) which is the nodal ministry of the above Matsya 6000, India’s deep ocean mission multi-institutional ambitious mission.  

Earth Sciences Minister Kiren Rijiju visited NIOT in Chennai on Monday, where he reviewed the submersible and provided updates on India’s first manned deep ocean mission. He posted on X (formerly Twitter), “ Next is ‘Samudrayaan’. This is the ‘MATSYA 6000‘ submersible under construction at the National Institute of Ocean Technology in Chennai. India’s first manned Deep Ocean Mission ‘Samudrayaan’ plans to send 3 humans in 6-km ocean depth in a submersible, to study the deep sea resources and biodiversity assessment”.

Working on Matsya 6000

The working of the Matsya 6000 will be as follows:

 It will be deployed by a ship in the ocean and once deployed from the ship the pilot can steer the vehicle under water.

Then the crewmen can get a view of the seafloor through a glass pane.

Then they can collect samples with the robotic hand attached to the vehicle for sample collection for further deep ocean resource research.


After a successful touchdown on the Chandrayaan-3 spacecraft on the lunar surface, India is all set to send three humans in 6 km ocean depth in its first manned deep ocean mission ‘Samudrayaan’. With the promotion of the national motto that is ATAMANIRBHAR BHARAT, India will touch all the peaks, either in space, defense, or the deep ocean with this first-ever Manned submersible vehicle without disturbing the marine ecosystem.

Only five nations – France, the US, China, Russia, and Japan – have thus far created many submersibles. And now India is going to add to the above list. India will have to play a critical and leadership role in the exploration of the ocean and develop resources in a sustainable manner for a balanced ecosystem.
