The proposed all-cargo version of the Airbus A350 XWB will offer Boeing MD-11F levels of payload and volume, but development is unlikely to begin until work on all the passenger models is completed.
Airbus plans to use the A350-900 variant as the basis for the freighter, which will follow the passenger versions of the twinjet that are due to enter service in 2013 (-900), 2014 (-800) and 2015 (-1000). A -900R extended-range version is also planned.
Airbus says that as now proposed, the A350-900F will have a similar payload and volume to the MD-11F, and a range of 9,250km (5,000nm).
I wonder what GE will think of this. They dont like competing with their own Boeing product on the 777 and have even pulled the CF6 from the A330F programme. The A350F would be a serious blow to the 777F.
