PN celebrates 49th Hangor Day to remember historic event National December 10, 2020 ISLAMABAD: Pakistan Navy celebrated 49th Hangor Day to commemorate the historic event, in which Pakistan Navy Submarine Hangor sank Indian Navy Frigate Khurki and crippled INS Kirpan in 1971 war in a spectacular war action. In order to pay tribute, Pakistan Navy celebrates 9th December as Hangor Day, which is reminiscent of unmatched courage and unwavering commitment of Pakistan Navy’s Submarine Hangor during 1971 war. This year also an impressive ceremony was held at PN Dockyard Karachi to mark Hangor Day. Commander Pakistan Fleet, Rear Admiral Naveed Ashraf, graced the ceremony as chief guest. Submarine Hangor remained a pride for Pakistan Navy in 1971 war and her gallant action was not only a spectacular tactical battle, resulting in sinking of Indian Navy's Frigate but it was a strategic overture of Pakistan Navy, which effectively thwarted and marginalised Indian aggression, imposed on Pakistan during 1971 war.
