turbines, 50000 shp, 27 knots
Description: These vessels were originally intended as part of an eight ship class Area AAW combatants. The Tartar missile would have been the primary weapon system but the expense caused the program to be abandoned. Instead the four vessels built were fitted for ASW duties self defence AAW capability. A large helo pad was fitted aft with two hangars for Sea King helicopters. From the late 1980s the ships entered the Tribal Update & Modernization Program (TRUMP). This removed the 127mm gun from the "A" position and fitted a 29 cell Mk 41 VLS in its place. The original pair of WM-22 fire control radars were replaced with STIR 1.8 radars to illuminate for the SM-2MR SAMs of the VLS. An OTO Melara 76mm gun was fitted just forward of the bridge and a Phalanx CIWS atop the hangars. The Sea Sparrow launchers and the Limbo ASW mortar were removed.
