Airbus says it aims to sell 210 of its much-delayed A400M military airlifters to the U.S.

Domingo Urena, director general of EADS N.V.'s defense unit Airbus Military, said Monday that the U.S. was a key market for the A400M, a four-engine turbo prop under development that has been plagued by delays and cost overruns.

Urena says Airbus Military hopes to sell 500 of the aircraft in addition to the 184 that have already been ordered by the project's seven founding customer nations — Belgium, Britain, France, Germany, Luxembourg, Spain and Turkey.
