Defence Minister Manohar Parrikar immediately ordered the navy chief to personally inquire into what this meant for India's maritime security.
Like in the previous case, the newspaper has blacked out all details which it felt would compromise India's security interests.
The leaked documents include details of submarine's underwater sensors, above-water sensors, combat management system, torpedo launch system and specifications, communications system and navigation systems.
Christened 'Vela', the submarine was launched on May 6, 2019, and has completed all major harbour and sea trials including weapon and sensor trials despite COVID-19-induced restrictions, the Navy said.
The National Security Strategy document should flag all major issues concerning security strategy and provide guidelines to concerned departments to work out suitable action plans. Since the global and regional geopolitical canvas is dynamic, the NSS document should be deliberated at length before formulation and should be reviewed periodically, recommends Commodore Venugopal Menon (retd).
As a debate raged over sensitivity of leaked Scorpene data, Defence Minister Manohar Parrikar on Friday played down the leak, saying it is "not a big worry" as weapon system details were not included, a remark challenged by the publisher who asserted these will be made public on Monday.
The status of the current submarine force level is alarming and we need to address the threat perceptions expeditiously. Critical decisions pertaining to national security cannot be delayed any further due to the rapidly changing maritime threat perceptions and growing strategic importance of the Indian Ocean region, asserts Commodore Venugopal Menon (retd).
Officials hint the visit could finally see a formal defence industrial road map being adopted by both nations.
Hydrography (underwater geography) prevents the Indian Navy for opting for an all-conventional, or all-nuclear submarine fleet.
An ill-informed public narrative centres on expensive weapons platforms instead of the little things that would improve capability.
'The government has belied the hope that many harboured of change, efficiency and dismantling old practices as the defence ministry continues to pursue the same well trodden and wasteful path.'
