(The Hindu) Indigenous nuclear submarine INS Arihant has suffered major damage due to ”human error” and has not sailed now for more than 10 months, say sources in the Navy.

Arihant is the most important platform within India’s nuclear triad covering land-air-sea modes.

Arihant’s propulsion compartment was damaged after water entered it, according to details available with The Hindu. A 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 did not respond to questions from The Hindu.
