Context: India’s first manned submersible, Matsya 6000, is set to be launched by 2026 under the Deep Ocean Mission, as confirmed by Union Minister.

• Only five nations (US, France, China, Russia, Japan) have developed manned deep-sea submersibles.

About Matsya 6000:

• What is Matsya 6000?

• • Matsya 6000 is a deep-sea manned submersible designed for underwater exploration.
  • Developed under the Samudrayaan Project, part of the Deep Ocean Mission (DOM).
  • Built by the National Institute of Ocean Technology (NIOT), Chennai.

• Ministry and Budget:

• • Implemented by the Ministry of Earth Sciences.
  • Part of the ₹4,077 crore Deep Ocean Mission aimed at deep-sea exploration.

• Aim and Objectives:

• • Explore deep-sea biodiversity and marine ecosystems.
  • Survey mineral resources such as cobalt, manganese, and copper.
  • Support oceanic research and promote marine tourism and literacy.
  • Enhance India’s technological capabilities in manned deep-sea exploration.

• Key Features of Matsya 6000:

• • Deep-sea Capability:
    • Designed to operate at 6,000 meters depth for up to 12-16 hours.
    • Emergency endurance of 96 hours for crew safety.
  • Structural Design:
