Alamgir (Gearing) Class

DESCRIPTION

These are former US GEARING-class destroyers of World War II construction. All have been refitted under the Fleet Rehabilitation And Modernization (FRAM) program, which included the addition of facilities for a Drone Anti-Submarine Helicopter (DASH), removal of a twin 5-in (127-mm) gun mount, installation of ASROC, and a general updating. Subsequently, a widened and strengthened flight deck was fitted to accommodate an Alouette III anti-submarine helicopter, but these facilities are not normally used.

These are flush-deck ships with a pronounced sheer toward the bow. When transferred, the main gun armament consisted of two 5-in (127-mm) dual-purpose gun mounts, one forward and the other aft; the after mount was later removed in several ships and replaced by a Phalanx Close-In Weapons System (CIWS) mount. An 8-barrel ASROC anti-submarine rocket launcher is fitted between the funnels and the torpedo tubes are ahead of the bridge on the forward part of the superstructure.

All of the ships were refitted at Karachi with the AN/SQS-23 sonar being upgraded to the solid-state, SQS-23D configuration. Several ships also received the Phalanx CIWS mount.

Beginning with the SHAH JAHAN, 3 twin launchers for the Harpoon anti-ship missile were fitted to increase the surface warfare effectiveness of these ships. All have had their WLR-1 Electronic Support Measures (ESM) system replaced with the Argo Phoenix II.

STATUS

The TARIQ and TAIMUR were purchased from the United States in 1977; they were both overhauled at the Puget Sound Navy Yard and were delivered to Pakistan in 1978. The TUGHRIL and TIPPU SULTAN were transferred in 1980, the ALAMGIR in 1982, and the SHAH JAHAN in 1983. SHAH JAHAN was destroyed as a missile target in the early 1990s. All are having their Phalanx and Harpoon weapon systems removed to update the TARIQ class ships now in service.
