History in the Pakistan Navy
Charity was sold to the United States Navy on 16 June 1958, for further transfer to the Pakistan Navy. She was renamed Shah Jehan. She was modernized by J. Samuel White in Cowes, England under a US contract and transferred to the Pakistan Navy as part of the Military Assistance Program on 16 December 1958 where she served as PNS Shah Jahan (literally, "Emperor of the World", after Shah Jahan).

Indo-Pakistan War of 1971
During the Indo-Pakistan War of 1971, Shah Jahan was escort to the cargo ship MV Venus Challenger carrying ammunition sent by the United States for the war effort from Saigon to Karachi.

On the night of 4 December 1971, the Indian Navy launched a fast naval strike called Operation Trident on the Pakistani Naval Headquarters of Karachi. The Operation Trident task force consisted of 3 Vidyut class missile boats from the 25th "Killer" Missile Boat Squadron (INS Nipat (K86), INS Nirghat (K89), and INS Veer (K82)), escorted by two Petya-class frigates, Tir and Kiltan, and two anti-submarine patrol vessels approached Karachi.

The Indian missile boats evaded Pakistani reconnaissance aircraft and patrol vessels and converged at 2150 hours about 70 miles south of Karachi, and detected the Pakistani naval vessels on patrol. At 2300 hours, Nipat fired 2 SS-N-2 Styx missiles at Shah Jahan and Venus Challenger. The ammunition aboard Venus Challenger exploded when the ship was hit by the missile, and the vessel quickly sunk. Shah Jahan was also struck by the missile and was irreparably damaged. She was towed back to Karachi and scrapped.

The Pakistani destroyer Khaibar and minesweeper Muhafiz were also sunk in the operation.
