HTMS Bhumibol Adulyadej

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.

Design

HTMS Bhumibol Adulyadej was constructed in South Korea. It is the first ship of the High-Performance Frigate Boat Project of the Royal Thai Navy. It is able to perform 3D combat operations on both the surface, underwater and air. It was commissioned on January 7, 2019, with the original name as HTMS Tha Chin. Later, with the royal benevolence of His Majesty King Vajiralongkorn, bestowed with the new name HTMS Bhumibol Adulyadej.[3]
