 After the war, President Richard Nixon forgave the remaining debt of "Ghazi" to Pakistan when the U.S. Navy's CNO Admiral Elmo Zumwalt visited Admiral Mohammad Shariff in Calcutta in 1972.In addition, she remained the first and to-date the only U.S.-built submarine to have served in the Pakistan Navy, although in successive years, only surface warships had been acquired through transfers from the United States as Pakistan worked towards building its own long-range submarines, the Agosta 90B, through a technology transfer from France.At the Naval Dockyard in Karachi, a 'Ghazi Monument' was built to perpetuate the memory of the submarine and its 93 men.
