The four-way battle for the Western millitary airlift market has never been more intense. The Boeing C-17 is fighting to survive even as Airbus Military pulls the A400M through fiscal uncertainty and Lockheed Martin's C-5M re-engining programme breathes new life in the venerable strategic airlifter.

The stage is set for surprises as Boeing and Lockheed contemplate dramatic configuration changes to the C-17 and C-130J, respectively and Airbus plays a US wild card having identified a gap in the US Air Force's otherwise robust airlift capability. It is a new era in the competition for aircraft.
