PNS Ghazi (SS 479) was a United States-built submarine that was leased to Pakistan in 1963. It was the first submarine to be operated by the Pakistan Navy and saw action in the 1965 and 1971 wars between India and Pakistan. The submarine could be armed with up to 28 torpedoes and, in later years, was re-fitted in Turkey for mine-laying capability. It remained the PN's flagship submarine until it sank near the eastern coast of India during the 1971 Indo-Pakistani War. According to a neutral source it sank enroute to the Bay of Bengal under mysterious circumstances. Several sources claim the Ghazi was sunk by the Indian Navy destroyer INS Rajput; however, other sources dispute this claim, citing unknown circumstances.
