General Atomics AeroTec Systems: third modernised Dornier 228 delivered to Royal Thai Navy

The RTN operates a fleet of seven Do228 aircraft, which are being comprehensively upgraded to meet the demands of contemporary maritime missions. The programme is carried out in collaboration with the U.S. Department of Defense under the DoD Grant Assistance Programme through the Indo-Pacific Maritime Security Initiative.

Each aircraft undergoes full refurbishment, including a structural inspection and replacement of key structural elements. A central upgrade is the installation of a “New Generation” glass cockpit, replacing older analogue instruments with a digital interface already used in the Do228 NXT production line.

“The project aims to adapt the mission-proven Do228 to the requirements of modern missions,” a GA-ATS representative noted, emphasising the platform’s continued reliability and adaptability. The fourth aircraft in the programme is already undergoing maintenance at GA-ATS facilities.

The Do228 has long served the Royal Thai Navy in coastal surveillance roles. As part of the modernisation, the aircraft are now equipped with advanced mission technology, including a 360-degree radar, an electro-optical infrared camera, a data link system, and an automatic ship identification system.

The interior has also been overhauled with an ergonomic mission management console for efficient planning, data analysis, and operation of surveillance equipment. Specially designed operator and observer seats have been added to support a range of operational scenarios.

Another advantage of the Do228 is its high operational flexibility. The cabin can be rapidly reconfigured to support roles such as cargo transport or medical evacuation.

After passing rigorous ground and flight testing, the third aircraft was ferried to Thailand and formally handed over to the RTN. “With this third delivery, GA-ATS underlines its expertise in the modernization of the Do228 and continues its successful cooperation with the Royal Thai Navy and the US Department of Defense,” the company stated.
