C-17A环球大师III的照片库，波音C-17环球大师III是一架大型军用运输机。它是由麦克唐纳·道格拉斯从20世纪80年代到90年代初为美国空军（USAF）开发的：该公司后来与波音公司合并。C-17用于快速战略空运部队和货物到世界各地的主要作战基地或前沿作战基地。它还可以执行战术空运、医疗后送和空投任务。C-17搭载着前两架但无关的活塞发动机、美国军用货机、道格拉斯C-74环球大师和道格拉斯C-124环球大师II。

Bridging the Gap
这 C-17 Globemaster III is the most flexible cargo aircraft in the world. Before the C-17, the military had to choose: use the massive C-5 Galaxy for long hauls to big airports, or the C-130 Hercules for short hauls to dirt strips. The C-17 was designed to do both. It can carry an M1 Abrams tank across the Atlantic Ocean and land it directly on a short, unpaved runway near the front lines. Its massive T-tail and “winglets” make it unmistakable in the sky, serving as the primary backbone for U.S. and Allied global power projection.

Design Engineering: Blown Flaps and Reverse Thrust
- Externally Blown Flaps: To land on short runways, the C-17 uses a “powered lift” system. The engine exhaust is directed directly onto the massive flaps when they are extended, doubling the lift and allowing the plane to fly at remarkably slow speeds during approach.
- Full Reverse Thrust: The C-17 can engage its thrust reversers in flight to descend rapidly (up to 15,000 feet per minute). On the ground, the reversers can push the plane backwards up a 2% grade, allowing it to “three-point turn” on narrow airfields.
- The “Moose” Nickname: It earned the name “Moose” because of the distinct groaning sound it makes during ground refueling and the venting of its pressure relief valves, which sounds like a moose call.
- The Integrated Cargo System: The floor features rows of rollers that can be flipped over by a single loadmaster. One side is flat for vehicles (like the Stryker or Abrams), and the other side has rollers for standard pallets.
Operational History: The World’s 911 Call
- The Kabul Airlift (2021): The C-17 became a global symbol of humanitarian effort during the evacuation of Afghanistan. One flight, “Reach 871,” famously carried 823 passengers in a single sortie—over three times its standard troop capacity.
- Special Operations: Because it is surprisingly quiet for its size and can land on unprepared surfaces, the C-17 is often used for covert night-time insertions of Special Forces units and their specialized vehicles.
- Antarctic Support: The C-17 is a frequent visitor to McMurdo Station in Antarctica. It can land on “ice runways” that would shatter the landing gear of most other heavy jets, thanks to its rugged, multi-wheel main gear.
- Global Partnership: While built by Boeing in the U.S., the C-17 is operated by the UK, Australia, Canada, India, Kuwait, Qatar, the UAE, and a joint NATO wing in Hungary, making it the international gold standard for heavy lift.
