Sinking

After the beginning of hostilities on 3 December 1971, Indian Naval radio detection equipment identified a submarine lurking about south-west of Diu harbour. The 14th Frigate Squadron of the Western Fleet was dispatched to destroy the submarine. It normally consisted of five ships, ''Khukri'', , ''Kalveti, Krishna'' and ''Kuthar,'' but at the time of the incident ''Kuthar''s boiler room was being repaired in Bombay. One reason that may have prompted the decision to deploy two obsolete ''Blackwood''-class frigates against a modern ''Daphne''-class submarine was that the Indian Navy lacked sufficient numbers of anti-submarine aircraft. The submarine sighted the squadron on the evening of 9 December. ''Khukri'' was still not aware of the submarine's presence and continued slowly on a steady course because she was testing an improved version of the 170/174 sonar, which required a low speed to increase detection, despite the fact that moving on low speed was against Indian anti-submarine doctrine. At 19:57 ''Hangor'' fired a homing torpedo on a sonar approach at ''Kirpan''. The torpedo did not explode and was detected by ''Kirpan'' which turned away and fired anti-submarine mortars. ''Khukri'' increased its speed and turned towards the submarine, which then fired a second torpedo directed at ''Khukri''. The torpedo struck ''Khukri'' and exploded under its oil tanks. According to the Pakistani submarine captain, Commander Ahmed Tasnim, the ship sank within two minutes.Interview with Vice Admiral Tasneem, December 2008
/ref> Other sources claim that ''Khukri'' was struck by three torpedoes before going down. After a few minutes, ''Kirpan'' attacked ''Hangor'' with depth charges, as her anti-submarine mortars were no long functional. ''Hangor'' then fired a final torpedo at ''Kirpan'' before leaving the area. ''Hangor'' patrolled the region for the next four days before returning safely to her berth.

Casualties

''Khukri'' is the only ship lost in combat in the history of the Indian Navy.

Controversy

Responsibility for errors by Indian naval officers related to the sinking has caused some controversy. The naval officer who led the inquiry into the sinking, Benoy Bhushan, has claimed that India's official naval history invented fictional accounts to cover up bungling and a surviving sailor from the frigate, Chanchal Singh Gill, has called for an investigation and withdrawal of gallantry awards to negligent officers in the squadron.
