Accidents in the Indian navy have been attributed to ageing ships in need of maintenance, delayed acquisitions by the Ministry of Defence, and human error.[308] However naval commentators also argue that as India's large navy of 160 ships clocks around 12,000 ship-days at sea every year, in varied waters and weather, some incidents are inevitable.[309] Captains of erring ships are dismissed from their command following an enquiry.[310] The accident on board INS Sindhuratna led to the resignation of the then Chief of Naval Staff (CNS) Admiral D K Joshi on 26 February 2014, who owned moral responsibility.[311] The navy is envisaging a new 'Safety Organisation' to improve safety of its warships, nuclear submarines and aircraft in view of its planned increase in fleet strength over the next decade.[312]
