HTMS Bhumibol Adulyadej (FFG-471) (Thai: เรือหลวงภูมิพลอดุลยเดช), is the lead ship of her class of frigates for the Royal Thai Navy, developed from the Gwanggaeto the Great-class destroyer. The DW-3000F hull is different from the Gwanggaeto the Great-class destroyer, due to the design of the ship having reduced radar cross section, and there are many other additional technologies added.
