The A330 MRTT+ Program: Evolution and Technical Capabilities

The Airbus A330 MRTT is the most widely adopted aerial refueling platform outside the United States, with more than 90% market share among non-U.S. operators. Over 17 countries have ordered the aircraft, and by June 2025, 65 out of 84 ordered units had been delivered. The MRTT+ represents the latest evolution, built on the A330neo airframe, and incorporates significant advances in fuel efficiency, range, and mission flexibility.

The MRTT+ features the A330-800’s new wing design, “sharklet” wingtips, and twin Rolls-Royce Trent 7000 engines. These enhancements deliver an 8% improvement in fuel efficiency and an 8% increase in operational range compared to the earlier A330-200-based MRTT. The maximum take-off weight has also been increased to 242 tonnes, allowing for greater payload and mission flexibility.

Key technical specifications include a maximum fuel load of 111 tonnes, a length of 58.8 meters, a wingspan of 60.3 meters, and a flexible configuration that can support up to 380 passengers in a single-class layout or 130 stretchers for medical evacuation. The MRTT+ is equipped with both boom and hose-and-drogue refueling systems, ensuring compatibility with a wide range of receiver aircraft, including Thailand’s mixed fleet of F-16s and Gripens.
