New Delhi [India], December 10 (ANI): Union Minister Jitendra Singh announced India's next major leap in ocean exploration with the unveiling of Matsya 6000, the country's "first indigenously developed human deep-sea submersible".
Showcased by the Ministry of Earth Sciences at IISF 2025, the mission aims to send Indian researchers to extreme ocean depths.
Sharing the update on X on Tuesday, Singh wrote, "Here is India's ambitious plan to send one human deep-sea submersible, providentially around the same time when preparations are in the final stage to send a human into Space. Meet Matsya6000, India's first indigenously developed human deep-sea submersible, showcased by the Ministry of Earth Sciences MoES at IISF2025."
Highlighting the ambitious timeline, Singh said that the submersible is targeting its first 500-metre manned dive in 2026, followed by a full-depth 6,000-metre mission in 2027. Once achieved, India will join the few nations with ultra-deep-sea exploration capability.
"With a target for its first 500 m manned dive by 2026 and 6000 m by 2027, Matsya 6000 will put India among the few nations with ultra-deep-sea exploration capability," Singh's X post further read.
