I'm an expert in the field of aviation and aerospace technology, with extensive knowledge of various aircraft, including the C-17 Globemaster III. The C-17 is a large military transport aircraft developed by McDonnell Douglas, now a division of Boeing. It's designed to carry out a wide range of missions, from tactical airlift and airdrop missions to humanitarian relief and other strategic airlift operations.

When discussing the weight of the C-17, it's important to distinguish between different aspects of its weight profile. The **C-17 has a maximum payload capacity of 170,900 pounds**, which means it can carry up to this weight in cargo, personnel, or a combination of both. This payload capacity is a critical factor in determining the aircraft's utility and effectiveness in various mission scenarios.

Furthermore, the **maximum gross takeoff weight of the C-17 is 585,000 pounds**. This figure includes the weight of the aircraft itself, its payload, fuel, and any other equipment or supplies on board. The gross takeoff weight is a key parameter for pilots and mission planners, as it influences the aircraft's performance, including its range and speed.

With a payload of 130,000 pounds, the C-17 can achieve an **unrefueled range of approximately 5,200 nautical miles**. This range is impressive and allows the aircraft to fly long distances without the need for mid-air refueling, which is particularly useful for strategic airlift missions.

The C-17's **cruise speed is approximately 450 knots (.77 Mach)**, which translates to a high-speed flight capability that enables it to quickly reach its destination. The speed, combined with the aircraft's range, makes the C-17 a formidable asset in the skies.

The C-17's performance specifications are the result of careful engineering and design, aimed at providing the U.S. Air Force and other international operators with a highly capable and versatile aircraft. Its weight and payload capacities, along with its speed and range, are among the many attributes that make the C-17 a critical component of modern airlift operations.

In summary, the C-17 Globemaster III is a highly capable military transport aircraft with a maximum payload capacity of 170,900 pounds and a maximum gross takeoff weight of 585,000 pounds. Its impressive performance, including a cruise speed of 450 knots and an unrefueled range of 5,200 nautical miles, makes it an invaluable asset for a variety of missions.
