The C17 Globemaster III is a large military transport aircraft developed by McDonnell Douglas, now a part of Boeing. Designed for rapid strategic airlift of troops and cargo, it is an essential tool for global military operations.

Dimensions

The aircraft is notable for its impressive dimensions:

• Length: 174 feet (53 meters)
• Wingspan: 169.8 feet (51.75 meters)
• Height: 55.1 feet (16.79 meters)
• Wing area: 3,800 square feet (353 square meters)

These dimensions enable the aircraft to handle bulky cargo and a large number of troops effectively.

Performance

The C17 has been engineered for high performance:

• Maximum speed: 515 mph (830 km/h) at 28,000 feet
• Cruising speed: 450 mph (724 km/h)
• Stall speed: 115 mph (185 km/h)

Its range is equally impressive:

• Ferry range: 5,610 miles (9,000 kilometers) with no payload
• Range with max payload: 2,420 miles (3,890 kilometers)

The C17 needs this kind of performance for quick deployment in various terrains and conditions across the globe.

Payload Capacities

The aircraft is designed to carry significant payloads:

• Maximum payload: 170,900 pounds (77,519 kilograms)
