The F-22P frigates are a class of multi-mission frigates built for the Pakistan Navy by China. Four frigates were ordered under a 2005 deal, with the first delivered in 2009. The frigates are based on China's Type 053H3 design but with stealth capabilities. They are equipped with missiles, torpedoes, guns and helicopters to detect and attack other ships and submarines. The frigates provide the Pakistan Navy with an upgraded fleet and ability to operate in hostile environments.
