India’s fourth-generation deep-ocean submersible, Matsya-6000, has successfully completed wet testing at the harbour, moving closer to shallow-water trials at 500 meters depth by late 2025.
Before wet testing, Matsya-6000 underwent integrated dry tests and was later transported to Kattupalli Port near Chennai for further trials.
Developed under the Samudrayan Project, the submersible is part of India’s Deep Ocean Mission, led by the Ministry of Earth Sciences and National Institute of Ocean Technology (NIOT). It features a 2.1-meter spherical hull designed to accommodate three crew members, enhancing India’s deep-sea exploration capabilities.
