India’s maiden manned ocean mission Samudrayaan has taken a major step forward, with ISRO announcing successful testing of the personnel sphere for the Matsya-6000 submersible at VSSC. The titanium sphere, 2,260 mm in diameter, can withstand 600 bar pressure and will carry a three-member crew 6 km underwater.
A key milestone was achieving high-penetration Electron Beam Welding of 80-mm thickness over 7,100 mm—done for the first time in India. ISRO partnered with NIOT under the Deep Ocean Mission. The LPSC in Bengaluru developed the welding and non-destructive evaluation (NDE) processes. Upgraded EBW and X-ray facilities were used to certify the human-rated sphere, marking a significant advancement for India’s deep-sea exploration ambitions.
