C-17A Globemaster III의 사진 갤러리, Boeing C-17 Globemaster III는 대형 군용 수송기입니다. McDonnell Douglas가 1980년대부터 1990년대 초반까지 미 공군(USAF)을 위해 개발했습니다. 회사는 나중에 보잉과 합병되었습니다. C-17은 전 세계 주요 작전 기지 또는 전방 작전 기지로 병력과 화물을 전략적으로 신속하게 공수하는 데 사용됩니다. 또한 전술적 공수, 의료 후송 및 공수 임무를 수행할 수 있습니다. C-17은 이전의 두 대의 피스톤 엔진과 관련이 없는 미군 화물기인 Douglas C-74 Globemaster와 Douglas C-124 Globemaster II의 이름을 따왔습니다.

Bridging the Gap
Tthe 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.
