High Quality Content by WIKIPEDIA articles! Jianghu class (Type 053H) is the NATO code-name for several types of frigates, currently in service with the People's Liberation Army Navy (PLAN). In the PLAN, the Jianghu-class is part of the Type 053-series frigate family. The early variants are small and obsolete, and now primarily used for coastal duty. The latest version is exported as F-22 (Frigate-22). The Type 053 Frigate has been exported to Egypt (2), Bangladesh (2), Thailand (4), and Pakistan has signed agreement to purchase 4 F-22P frigates in May 2006. The use of NATO code-name vs. PLAN ship type is often confusing. For purpose of clarification, this article will briefly discuss all versions of the Type 053 frigates.
