Thailand’s RTAF to Acquire Aerial Refueling Tanker: A Major Leap in Air Power Projection
This acquisition is expected to significantly bolster Thailand’s air power projection, ensuring sustained air superiority and operational flexibility in the region.
(DEFENCE SECURITY ASIA) – In a move to enhance its strategic air operations, the Royal Thai Air Force (RTAF) has officially announced plans to acquire an aerial refueling tanker, a critical asset that will extend the operational reach of its F-16 Fighting Falcon and JAS 39 Gripen fighter jets.
This acquisition is expected to significantly bolster Thailand’s air power projection, ensuring sustained air superiority and operational flexibility in the region.
The procurement forms part of RTAF’s broader modernization program, aimed at equipping the air force with next-generation capabilities to meet evolving security threats and operational demands.
During the 88th Anniversary of RTAF, Air Chief Marshal Phanphakdee Phattanakul, RTAF Commander, confirmed that the tanker will be specifically tasked with air-to-air refueling operations, supporting both boom and multi-point refueling systems to accommodate different aircraft configurations.
The new tanker will replace RTAF’s Airbus A340-500, which has primarily served in VIP transport and long-range airlift operations.
However, the replacement aircraft will not only function as a refueling platform—it will also be capable of VIP transportation and medical evacuation (MEDEVAC) missions, akin to the Republic of Singapore Air Force (RSAF)’s Airbus A330 MRTT (Multi Role Transport Tanker).
Currently, Singapore remains the only Southeast Asian nation operating a dedicated aerial refueling fleet, with six Airbus A330 MRTTs based at Changi Air Base (East).

If Thailand’s procurement proceeds as planned, RTAF could become the second air force in the region to deploy a modern multi-role tanker, elevating its strategic capabilities.
If approved, the new tanker is projected to enter service between 2028 and 2029, aligning with Thailand’s 2024 Defense White Paper, which highlights the urgent need to modernize the country’s existing aerial refueling capabilities.
The document emphasizes the requirement for an aircraft capable of intercontinental operations, particularly one that can evacuate Thai nationals during global crises.
This priority was underscored several months ago when RTAF deployed its Airbus A340-500 to evacuate Thai citizens freed from Hamas captivity—demonstrating the importance of long-range, multi-mission aircraft in national security operations.
RTAF is currently evaluating three aircraft as potential candidates for its new aerial refueling and multi-role transport fleet:
-
Airbus A330 MRTT
-
Boeing KC-46 Pegasus
-
Boeing KC-135 Stratotanker
Each aircraft presents distinct operational advantages and challenges, requiring a thorough assessment based on Thailand’s mission profiles and defense requirements.

The Airbus A330 MRTT is a combat-tested, next-generation aerial tanker, widely regarded as one of the most capable refueling platforms in the world today.
It boasts exceptional fuel capacity, extended operational range, and versatile air-to-air refueling (AAR) capabilities, making it the preferred choice for multiple NATO and allied air forces.
Equipped with both boom and probe-and-drogue systems, the A330 MRTT can refuel a wide variety of aircraft, including fighters, bombers, and surveillance platforms.
Additionally, it doubles as a high-capacity strategic transport aircraft, ideal for MEDEVAC missions, troop deployments, and large-scale logistics operations.
The Airbus A330 MRTT is powered by two Rolls-Royce Trent 700 or General Electric CF6 engines, enabling it to reach a maximum speed of 880 km/h with an operational range of 14,800 km while carrying up to 111 tons of fuel without additional tanks for extended aerial refueling missions.
Beyond its primary role, the aircraft is also designed for troop transport, cargo missions, and medical evacuation (MEDEVAC), making it a highly versatile asset in strategic air operations.
Developed for the U.S. Air Force, the Boeing KC-46 Pegasus is a highly advanced aerial tanker, featuring state-of-the-art fly-by-wire refueling boom technology, enhanced situational awareness systems, and high-survivability countermeasures, making it ideal for high-threat environments.

A key advantage of the KC-46 is its comprehensive electronic warfare protection suite, allowing it to operate in contested airspace—a crucial capability for modern warfare scenarios.
Apart from its refueling role, the aircraft is also capable of cargo transport and medical evacuation (MEDEVAC) missions, further increasing its strategic value.
The Boeing KC-46 Pegasus is equipped with two Pratt & Whitney PW4062 engines, allowing it to achieve a maximum speed of 915 km/h and an operational range of 11,830 km while carrying up to 96 tons of fuel for aerial refueling missions.
It also features a fly-by-wire boom and probe-and-drogue refueling systems, enabling it to support troop transport and MEDEVAC operations alongside its primary refueling role.
Meanwhile, the Boeing KC-135 Stratotanker holds the distinction of being one of the longest-serving aerial tankers in military history, having played a pivotal role in global air refueling operations since 1957.
Despite its age, the aircraft remains operationally effective, particularly in long-endurance missions supporting fighter aircraft and strategic bombers.
While the KC-135 offers excellent range and endurance, it lacks the multi-role versatility of newer platforms like the A330 MRTT and KC-46 Pegasus, making it less adaptable for future operational needs.
