There appears to have some missing links in this story. How can you accidentally keep a hatch open when the entire boat needs to be highly automated with instant detection if manual errors??? I'd like to read this incident coupled with the Russian allegation of their "leased" boomer being spied upon in India!!! And, that boat was also damaged in an accident and remains unmovable. Looks like some foul plays here!!! I think there're immense Russian inputs and collaboration for this class of indigenous boats. Meanwhile, Pak is going ahead with sub based nuclear tipped CMs....
