HTMS Naresuan (FFG-421) (Thai: เรือหลวงนเรศวร), commissioned in 1995, is a modified version of the Chinese-made Type 053 frigate, corporately designed between Royal Thai Navy and China but built by the China State Shipbuilding Corporation in Shanghai. Her sister ship, HTMS Taksin was delivered in November 1995. The ships cost 2 billion baht each.

The Royal Thai Navy complained of the poor quality of the ships. The ship's damage control system was very limited, with very basic fire suppression systems. It was claimed that if the ship's hull was breached, the ship would quickly be lost to flooding. The Thai Navy had to spend considerable time and effort to correct some of these issues.^[1]
