In all the cases, a Board of Inquiry (BoI) was set up to identify the cause and officials responsible, Minister of State for Defence Subhash Bhamre said in a written reply to a question in Rajya Sabha.
"During 2014, 2015, 2016 and 2017 (till date), Indian navy has reported 21 operational accidents involving naval vessels. Ten human lives were lost in these accidents.
"In majority of cases, the BoI is complete. Forty two officers/sailors have been held responsible in such cases. Disciplinary action has already been taken against 32 officers/sailors," Bhamre added.
