The Type 054 (NATO Codename Jiangkai I) frigate is a Chinese multi-role warship that were commissioned in the People's Liberation Army Navy Surface Force in 2005. They superseded the Type 053H3 frigates. Two ships, 525 Ma'anshan, and 526 Wenzhou, were completed before production switched to the improved Type 054A frigate.

The Type 054 has a stealthy hull design with sloped surfaces, radar absorbent materials, and a reduced superstructure clutter.

The main anti-ship armament were YJ-83 sea-skimming anti-ship cruise missiles in two four-cell launchers. It retained the HQ-7 SAM, an improved version of the French Crotale, from the preceding Type 053H3; the HQ-7 had a ready-to-fire 8-cell launcher, with 16 stored in the automatic reloader. Short range defence was improved with four AK-630 CIWS turrets. A 100 mm main gun, also based on a French design, was mounted.

Both ships were powered by four CODAD Type 16 PA6 STC marine diesel engines designed by SEMT Pielstick, each generating 6,330 hp. Licenses for the engines were sold to China in April 2002, where they were built by the Shaanxi Diesel Engine Factory. Other reports claimed each ship was powered by two (or four) Type 16 PA STC and two MTU 20V 956TB92 diesels.

The Type 054 resembled the French La Fayette-class frigates in shape and displacement. In addition, the Chinese used French, or French-derived, electronics and weapons. The French exported these systems to China in the 1980s, and later granted production licences. These systems were similar to those used on the La Fayettes in the 1980s.
