The Zulfiquar-class frigate, also known as F-22P or in English: Sword class, is a class of multi-mission guided missile frigates, in service with the Pakistan Navy. The class is based on an updated model of the Chinese design, the Type 053H3. The frigates were designed and built jointly in Hudong–Zhonghua Shipbuilding in China and the KS&EW Ltd. in Pakistan.

The Type 053H3 is a class of Chinese frigates that entered service with the People's Liberation Army Navy Surface Force in the 1990s and 2000s. The class comprised ten vessels, all of which remain in active service except for two which have been sold to the Bangladesh Navy. They were a follow-on of the Type 053H2G class. The Zulfiquar-class frigate used by the Pakistan Navy was based on the Type 053H3.
