The Khamronsin-class corvettes are three corvettes constructed for the Royal Thai Navy in the late 1980s. Based on a British design, all three ships were built in Thailand. A fourth vessel, constructed to a modified design, was built for the Thai Police and was the first to enter service in 1992. The three Khamrosin-class corvettes commissioned in 1992 and remain in service.
