The Airbus A330 Multi Role Tanker Transport (MRTT) is an aerial refuelling tanker aircraft based on the civilian Airbus A330. The A330 MRTT has been ordered by the Royal Australian Air Force (RAAF), Royal Air Force (RAF), United Arab Emirates Air Force, Royal Saudi Air Force and Republic of Singapore Air Force. The EADS/Northrop Grumman KC-45 was a version of the A330 MRTT proposed for the United States Air Force.

The A330 MRTT has a maximum fuel capacity of 111,000 kg (245,000 lb) without the use of additional fuel tanks, which leaves space for the carriage of 45,000 kg (99,000 lb) of additional cargo.
The A330 MRTT’s wing has common structure with the four-engine A340-200/-300 with reinforced mounting locations and provision for fuel piping for the A340’s outboard engines. The A330 MRTT’s wing therefore requires little modification for use of these hardpoints for the wing refuelling pods.
The A330 MRTT cabin can be modified to carry up to 380 passengers in a single class configuration, allowing a complete range of configurations from maximised troop transport to complex customisation suitable for VIP and guest missions. Available configurations include 300 passengers in a single class and 266 passengers in two classes.

The A330 MRTT can also be configured to perform Medical Evacuation (Medevac) missions; up to 130 standard stretchers can be carried. The main deck cargo configuration allows carriage of standard commercial containers and pallets, military, ISO and NATO pallets (including seats) and containers, and military equipment and other large items which are loaded through a cargo door. Like the A330-200, the A330 MRTT includes two lower deck cargo compartments (forward and aft) and a bulk area capability. The cargo hold has been modified to be able to transport up to 8 military pallets in addition to civilian Unit Load Device (ULD).
An optional crew rest compartment (CRC), located in the forward cabin can be installed for a spare crew to increase time available for a mission. The passenger cabin of the A330 MRTT can be provided with a set of removable airstairs to enable embarkation and disembarkation when airbridges or ground support equipment are not available.
Standard commercial A330-200s are delivered from Airbus Final Assembly Line in Toulouse (France) to Airbus Military Conversion Centre in Getafe, Spain for fitting of refuelling systems and military avionics. The tanker was certified by Spanish authorities in October 2010. It was first delivered to Australia on 1 June 2011. Qantas Defence Services converted the remaining four A330-200s at its Brisbane Airport facility on behalf of EADS for the Royal Australian Air Force.
The A330 MRTT has been ordered by Australia, United Kingdom, United Arab Emirates, Saudi Arabia and Singapore. Australia was the launch customer for the A330 MRTT.

In 2005, the RAAF expected that deliveries would begin in late 2008 and be completed in 2010. Deliveries fell two years behind schedule, in part because of delays in the boom’s development. On 30 May 2011, KC-30A A39-003, the third converted A330, arrived at RAAF Base Amberley and was formally handed over on 1 June 2011. The second A330 conversion, A39-002 was ferried to RAAF Amberley on 18 June 2011 and handed over to the RAAF on 22 June 2011. In June 2010, Qantas announced receipt of the fourth aircraft at its Brisbane facilities for an anticipated 10-month conversion. On 3 December 2012, the final fifth KC-30A was delivered to the RAAF.
In July 2013, it was reported there were ongoing delays with preparing the KC-30A for full entry into service due to problems with the refuelling systems, including the hose-and-drogue system passing too much fuel.
In August 2013, the KC-30A made its debut as a VIP transport, ferrying Prime Minister Rudd and an entourage to Al Minhad Air Base, United Arab Emirates. In August 2014, Defence Minister David Johnston announced the intention to purchase two additional KC-30As with one in VIP configuration for transport of the Prime Minister.
On 22 September 2014, the RAAF deployed an Air Task Group to a staging base at Al Minhad Air Base in the United Arab Emirates, as part of a coalition to combat Islamic State forces in Iraq.

The aircraft included F/A-18F Super Hornets, a KC-30A tanker transport and an E-7A Wedgetail airborne early warning and control aircraft. The KC-30 started operations just days after arriving in the UAE by aerial refueling US and other coalition aircraft over Iraq. On 6 October 2014, the RAAF started their first combat missions over Iraq with two Super Hornets supported by the KC-30 tanker.

In July 2015, Defence Minister Kevin Andrews announced the order of two additional KC-30s, to be delivered in 2018. The new tankers will be based on A330-200 airliners that were previously operated by Qantas on lease from CIT Aerospace, and will be the first KC-30As to be converted from airframes that have already seen civilian service.
France confirms order for eight Airbus A330 MRTT “Phénix” tanker aircraft
Airbus Defence and Space has received a firm order from the French Defence Procurement Agency (DGA) for a further eight A330 MRTT Multi-Role Tanker Transport aircraft. The aircraft constitute the second tranche of the multi-year contract for 12 A330 MRTTs signed by the French Ministry of Defence in November 2014 and bring the total firm order to nine. The remaining three are scheduled to be confirmed in 2018, permitting deliveries of the 12 aircraft before 2025.
The first A330 MRTT will be delivered to France in 2018, followed by the second in 2019, and the remainder at a rate of one or two per year.
In French service the A330 MRTT will be powered by Rolls-Royce Trent 700 engines and equipped with a combination of the Airbus Refuelling Boom System and underwing hose-and-drogue refuelling pods. It will also be possible to configure them in a variety of layouts carrying up to 271 passengers as well as medevac arrangements including the French MORPHEE intensive care module carrying up to ten patients as well as 88 passengers.
The combat-proven A330 MRTT has been ordered by seven nations which have now placed firm orders for 49 aircraft, of which 26 have been delivered. Source airrecognition.com
Germany and Norway sign up to European A330 tanker pool: Here
Germany and Norway have officially signed up to an effort led by European NATO members to jointly acquire and operate a pool of up to 11 Airbus Defence & Space A330 multi-role tanker transports (MRTT).
Initiated by the European Defence Agency in 2012, the programme initially counted Luxembourg and the Netherlands as its sole members.
