Key Indian nuclear submarine damaged

Indian nuclear submarine designed by Russia INS Arihant has suffered major damage due to ”human error” and has not sailed now for more than 10 months.
Arihant is the most important platform within India’s nuclear triad covering land-air-sea modes, The Hindu reported.
Submarine’s propulsion compartment was damaged after water entered it, according to details. An Indian naval source said water rushed in as a hatch on the rear side was left open by mistake while it was at harbour.The Ministry of Defence for India did not respond to questions by The Hindu.
Since the accident, the submarine, built under the Advanced Technology Vessel project (ATV), has been undergoing repairs and clean up, the sources said.
Besides other repair work, many pipes had to be cut open and replaced. “Cleaning up” is a laborious task in a nuclear submarine, the naval source said.
The Arihant issue rose soon after INS Chakra, the Nerpa class nuclear submarine leased from Russia, was reported to have suffered damage to its sonar domes while entering the Visakhapatnam harbour in early October.
