 Starting from being the only submarine in the Indo-Pakistani war of 1965, "Ghazi" remained the Pakistan Navy's flagship submarine until she sank under mysterious circumstances near India's eastern coast while conducting naval operations en route to the Bay of Bengal.While the Indian Navy credits "Ghazi"s sinking to its destroyer , the Pakistani military oversights and reviews stated that "the submarine sank due to either an internal explosion or accidental detonation of mines being laid by the submarine off the Visakhapatnam harbour".Indian historians consider the sinking of "Ghazi" to be a notable event and they have described the sinking as one of the "last unsolved greatest mysteries of the 1971 war."
