India’s first manned submersible, Matsya 6000, is expected to be launched by 2026. The submersible will carry three people to a depth of 6,000 meters to explore ocean biodiversity, survey marine resources, and assess mineral deposits. The project is part of India’s Deep Ocean Mission, aimed at advancing deep-sea exploration technologies and boosting the country’s capacity for sustainable underwater resource use.
