9th Dec known as Hangor Day is celebrated with fervor and zeal in order to pay tribute to the brave war veterans who struck terror in the hearts of the enemy by sinking the Indian Navy ASW Frigate INS KHUKRI and crippling INS KIRPAN during the 1971 war.
The spectacular war action took place 30 miles South East off ‘Diu Head’. The event is distinguished in naval history as being the first ever kill by a conventional submarine after World War-II. In recognition of their courage, the valiant crew of PNS/M Hangor was decorated with 04 x Sitara-e-Jurrats, 06 x Tamgha-e-Jurrats and 14 x Imtiazi Asnad.
On 9th December 1971, the UK build Indian Anti-Submarine frigate INS KHUKRI was sunk and INS KIRPAN was badly damaged by the Pakistani Submarine PNS/M Hangor. The significance of this encounter increases manifold when viewed in retrospect that it was only the first occasion after world War-II, that a War ship was sunk by a conventional S/M in a live encounter at sea. Although the sinking of Argentinean Cruiser Gen Belgrano by RN nuclear S/M HMS Conqueror in 1982 Falklands war is only the second such action/occasion in the present history; nevertheless, PNS/M Hangor till to date remains on the honour list as the only conventional submarine in the world to have achieved such a distinction.
