The C-17 Globemaster III is a large military transport aircraft developed by McDonnell Douglas, now part of Boeing. Designed for rapid strategic airlift, it can carry heavy cargo, troops, and equipment over long distances, and is known for its agility and capability to operate from short, austere runways. The C-17 is widely used by the U.S. Air Force and several allied nations for missions such as troop transport, medical evacuation, and humanitarian aid. With advanced avionics and a powerful, efficient design, it remains a crucial asset for global military logistics and support.
