PNS/M Hangor (S-131) (nicknamed: "Shark") was a Daphné-class diesel-electric submarine that served in the Pakistan Navy from 1969 until its decommissioning in 2006. It is the first submarine to sink a ship after World War II.

Hangor (S131) was the lead ship of her class, designed and constructed by France after a long and complicated negotiation which started in 1966.:63 In 1969, Hangor was commissioned in the Submarine Command (SUBCOM) when she reported back to her home base in Karachi from Paris. Hangor, under the command of Commander Ahmed Tasnim, sank the Indian Navy's INS Khukri, an anti-submarine frigate, with one homing torpedo on 9 December 1971 during the western front of the third war with India in 1971.

This was the only recorded submarine kill after World War II until the Falklands War, when the Royal Navy's nuclear submarine HMS Conqueror sank the Argentine Navy cruiser General Belgrano. The strategic impact was even more significant as the Indian navy cancelled "Operation Triumph", the third missile attack, which was to be launched on 10 December.
