Airbus A330-243 Multi Role Tanker Transport (c/n 1830, T-054 operated by Koninklijke Luchtmacht / the Royal Netherlands Air and Space Force), exercise Lion Effort 2024, Čáslav, May 2024.
The Airbus A330 Multi Role Tanker Transport (MRTT) was developed in the mid-2000s as a militarised variant of the popular A330 wide-body airliner, manufactured by Airbus since the early 1990s.
The MRTT is a dual-role aircraft that can perform both air-to-air refuelling and transport missions.
In its air-to-air refuelling configuration, the aeroplane can carry up to 111,000 kg of fuel (without additional tanks). The A330 MRTT can refuel other aircraft using both boom and probe refuelling systems, as well as can use the Universal Aerial Refuelling Receptacle Slipway Installation (UARRSI) for self, in-flight refuelling.
Depending on its particular cargo configuration, the A330 MRTT can carry up to 45,000 kg of payload or up to 380 passengers. The aircraft cabin can be adapted for various purposes, from carrying troops to VIP transport duties. In addition, the A330 MRTT can be used for medical evacuation, and its MEDEVAC configuration provides space for up to 130 standard stretchers.
The A330 MRTT performed its maiden flight on 15 June 2007. Almost exactly four years later, the first serially manufactured aircraft was officially handed over to its first customer, the Royal Australian Air Force (RAAF).
In the following years, the aircraft was ordered by about a dozen air forces around the world, with almost seventy aeroplanes of the type built by the end of 2025. According to the manufacturer, the A330 MRTT accounts for more than 90 per cent of the air-to-air refuelling aircraft market share outside the United States.
It is worth noting that several custom-tailored variants of the aircraft were developed. These include the aforementioned KC-30A/M for the RAAF, the KC-330 Cygnus for the Republic of Korea Air Force, the Voyager KC2 and KC3 for the Royal Air Force, and the Phénix for the French Air and Space Force.
The list of the newest customers includes the Royal Canadian Air Force, with nine CC-330 Husky aircraft already ordered (Canada awards Airbus a contract for new strategic tankers), the Royal Thai Air Force and, probably, the Brazilian Air Force.
Interestingly, the A330 MRTT won the 2008 US bid for a replacement of the ageing KC-135 fleet. The KC-30 variant, proposed by Northrop Grumman and EADS, was announced the winner against a Boeing-developed aircraft. However, the contract was later rebid, eventually in favour of Boeing.
All A330 MRTT aircraft are made by conversion of the existing A330-200 airliners. However, the number of available airframes is decreasing due to the end of production of the basic model, which was replaced by the A330neo in 2019.
In response to that issue, Airbus developed a new variant of the aircraft, designated MRTT+ and based on the A330-800 airliner. In 2024, during the Farnborough Air Show, information about the new aeroplane was officially disclosed to the public for the first time.
The A330 MRTT T-054 featured in our Photo of the Week series belongs to the Multinational Multi Role Tanker Transport Fleet (MMF) established by NATO. The MMF provides strategic transport, air-to-air refuelling and MEDEVAC capabilities to its eight participating nations: Belgium, the Czech Republic, Denmark, Germany, Luxembourg, the Netherlands, Norway and Sweden. The Multinational MRTT Unit (MMU) is based at two airfields: the Main Operating Base in Eindhoven, the Netherlands, and the Forward Operating Base in Cologne, Germany.
The pictured A330 was manufactured by Airbus in 2017. In August 2020, after being converted to the MRTT variant, the aircraft was acquired by the MMF, with its operation assigned to the Royal Netherlands Air and Space Force.
