About: Yanxi-class weapon trials ship

The Yanxi class weapon trials ship is a class of little known naval auxiliary ship of the People's Liberation Army Navy (PLAN). The name of this class is after the first unit commissioned, with the exact type still remains unknown. Contrary to the usual naming conventions of Chinese military where the ship is designated by a combination of two Chinese characters followed by three-digit number, the Yanxi class is designated by only a single Chinese character, which is Xun (训), short for Xun-Lian (训练), meaning training in Chinese, because these ships of this class is also used as training ships, but only a single unit of this class has been built. However, the pennant numbers may have changed due to the change of Chinese naval ships naming convention.
