Saudi Arabia has ordered another three Airbus A330 tankers, for aerial refueling and carrying cargo. The Airbus MRTT is based on the twin engine Airbus 330-300, which normally sells for $160 million each. The 233 ton MRTT carries 111 tons of fuel, plus 43 tons of cargo (26 pallets). The MRTT can also carry 238 passengers, because the main deck is available for passengers, cargo or fuel containers. Normally, all the fuel is carried in the wing and tail tanks. This makes the MRTT very flexible, and capable of moving lots of cargo or troops, as needed. Saudi Arabia had already ordered three A330 tankers last January. The first of these will be delivered in two years.
