The Naresuan-class frigate (Thai: นเรศวร) is a enlarged modified version of the Chinese-made Type 053 frigate with Western weaponry, cooperatively designed by the Royal Thai Navy and China but built by the China State Shipbuilding Corporation in Shanghai. The ships came at 2 billion baht each, less than the 8 billion baht claimed price tag for Western-built frigates.
