A high-wing, 4-engine, T-tailed military-transport aircraft, the multi-service C-17 can carry large equipment, supplies and troops directly to small airfields in harsh terrain anywhere in the world day or night. The massive, sturdy, long-haul aircraft tackles distance, destination and heavy, oversized payloads in unpredictable conditions. It has delivered cargo in every worldwide operation since the 1990s.

The C-17's ability to fly long distances and land in remote airfields in rough, land-locked regions make it a premier transporter for military, humanitarian and peacekeeping missions. It can:

Take off from a 7,600-ft. airfield
carry a payload of 160,000 pounds
fly 2,400 nautical miles
refuel while in flight
land in 3,000 ft. or less on a small unpaved or paved airfield in day or night.
Carry a cargo of wheeled U.S. Army vehicles in two side-by-side rows, including the U.S. Army's main battle tank, the M-1. Three Bradley infantry-fighting vehicles comprise one load.
Drop a single 60,000-lb. payload, with sequential load drops of 110,000 lb.
Back up a two-percent slope.
Seat 54 on the sidewall and 48 in the centreline.
