 Despite their obsolescence, these boats remained active well into the mid-1990s.Although the ships are no longer capable of venturing into open ocean, these units remain on the People's Liberation Army Navy’s list of its reserve fleet, actively used as weaponry training boats for naval militia in various military maritime districts in China.Additionally, vessels of this class in Chinese service are used to take Chinese children enrolled in military / naval summer camps and junior military / naval academies for short cruises for patriotic education and public relations missions.
