The Tughril-class frigates, formally classified as the Type 054A/P frigates, are a series of modified guided-missile frigates being built by Hudong–Zhonghua Shipbuilding (HDZH), for the Pakistan Navy. The Type 054A/P is a modified derivative of the Type 054A frigate and was specifically customised to meet the operational requirements of the Pakistan Navy; the class features several capabilities - including anti-surface warfare (ASuW), anti-aircraft warfare (AAW), anti-submarine warfare (ASW) and low radar observability. The frigates are poised to form the mainstay of the Pakistan Navy's active naval fleet. The class is also set to supplant Pakistan's obsolete Tariq-class destroyers.
