C-17 Globemaster III
The massive long-haul military transport aircraft tackles distance, destination and heavy, oversized payloads in unpredictable conditions.
Always Dependable. Always Ready.
A high-wing, four-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. 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.
Lifecycle Sustainment
Boeing has partnered with the U.S. Air Force on C-17 sustainment since the delivery of the first aircraft in 1993. With a focus on high performance at an affordable cost, Boeing provides sustainment and maintenance for global C-17 customers in eight allied countries. The C-17 fleet has a best-in-class combined dollar per flight hour and mission capable rate, performing at the highest level of readiness worldwide.
Support
Under the Globemaster III Sustainment Program contract, Boeing is fully responsible and accountable for total weapon system availability executing program management, sustaining logistics, material and equipment management, sustaining engineering and depot-level aircraft maintenance. On-site base support includes personnel for base management and operations support, field services and engineering technical support and 24/7 base supply support for spares.
Training
Train The Way You Operate
Boeing provides comprehensive C-17 Globemaster III training solutions for aircrews and loadmasters with advanced simulation, courseware and computer-based training. C-17 operators can practice the complete range of tasks required for tactical military airlift operations and humanitarian missions, along with rehearsal of other scenarios such as aerial refueling and emergency procedures.
