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.^[3]

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 (Thai: เรือหลวงท่าจีน). Later, with the royal benevolence of His Majesty King Vajiralongkorn, bestowed with the new name HTMS Bhumibol Adulyadej.^[4][5]

The ship was developed based on the South Korean Navy Gwanggaeto the Great-class destroyer (KDX-I). The ship was built at Daewoo Shipbuilding & Marine Engineering Co., Ltd, South Korea, from 2013 to 2018. The hull is designed using Stealth Technology. Both the hull and its systems are focused on reducing detection by opponents. And reduce heat radiation Reduces radar reflection and noise. The naval combat system is linked to the Air Force aircraft Link E, Link RTN, especially the link with HTMS Naresuan (FFG-421), HTMS Taksin (FFG-422) and HTMS Chakri Naruebet (CVH-911) with Link G, the Jas-39 Gripen multirole fighter aircraft is the Air Force's most advanced 4.5 generation fighter. As part of the development of Network Centric Warfare. High-performance frigates Designed hull and structure Support for improvements to be able to fire the RIM-66 Standard MR ground-to-air missile, including a plan to support it. The companies involved in the assembly system include the launch pad, the vertical missile launcher (Mk.41 VLS), the combat system. Fire control radar and target radar (Illuminator) can be improved to support the firing of such launch weapons when the Navy needs it and the budget situation allows.^[6]
