Boeing has revealed its latest thinking on how the
C-17 heavy airlifter could meet the joint future theater lift (JFTL) requirement that is emerging in the U.S. The “Advanced Tactical C-17” would retain the basic wings and tail of the current C-17A, but feature a new fuselage that is four feet narrower and consists of more composite structure. The four P&W F117 turbofans would be upgraded to provide 13 percent more thrust.
The design would also feature a new advanced flap design; blended winglets; a tire deflation and inflation system for soft-field landings; and various avionics improvements to allow autonomous and precision landings, and enhanced self-protection. This “narrowbody” C-17 could fly into 1,500-foot airstrips carrying two Stryker combat vehicles, according to Boeing. It would be 15 percent more fuel-efficient than the C-17A, but retain the ability to cruise in commercial airspace at Mach 0.80.
