1. Боинг C-17 Глоубмастър III е голям военнотранспортен самолет. Той е разработен за ВВС на САЩ (USAF) от 1980-те до началото на 1990-те години от McDonnell Douglas; по-късно компанията се слива с Boeing. C-17 се използва за бърз стратегически въздушен транспорт на войски и товари до основни оперативни бази или предни оперативни бази по целия свят. Той може също така да изпълнява тактически въздушен транспорт, медицинска евакуация и мисии за спускане с въздух. C-17 носи името на два предишни, но несвързани американски военни товарни самолета с бутален двигател, Douglas C-74 Globemaster и Douglas C-124 Globemaster II. Въпреки че вече не се купуват от ВВС на САЩ, C-17 се произвеждат за експортни клиенти.

The “Anywhere, Anytime” Heavy Lifter
1. C-17 Globemaster III is the premier strategic transport aircraft of the 21st century. Developed by McDonnell Douglas (now Boeing), it was designed to bridge the gap between the massive C-5 Galaxy and the rugged C-130 Hercules. It can carry a massive payload—including an M1 Abrams tank—directly from the United States to a dirt landing strip in a remote combat zone. This unique “strategic-to-tactical” capability has made it the primary tool for rapid troop deployment, humanitarian aid, and aeromedical evacuation worldwide.

Design Engineering: Blown Flaps & Thrust Reversers
- Externally Blown Flaps: To land a 265-ton aircraft on a short runway, the C-17 uses “blown flaps.” Engine exhaust is directed over and through the huge double-slotted flaps, creating massive amounts of extra lift even at slow speeds.
- Upward-Directed Thrust Reversers: The C-17 can back itself up an incline using its thrust reversers. Crucially, the air is directed upward and forward, preventing the engines from sucking up dust and rocks (FOD) while operating on unimproved dirt airfields.
- Tactical Descent: The C-17 is famous for its ability to perform “tactical descents” at rates of up to 15,000 feet per minute. By using its thrust reversers in flight as speed brakes, it can drop out of the sky quickly to avoid surface-to-air missiles.
- The T-Tail Design: The high-mounted T-tail keeps the horizontal stabilizers out of the turbulent air created by the wing and engines during high-lift maneuvers, ensuring the pilot maintains precise control during heavy-load landings.
Operational History: A Global Lifeline
- Kabul Airlift (Operation Allies Refuge): In 2021, the C-17 became the face of the evacuation from Afghanistan. One C-17 (Reach 871) famously carried 823 passengers in a single flight, far exceeding its “official” capacity to save lives.
- Humanitarian Giant: From the 2010 Haiti earthquake to the COVID-19 pandemic response, the C-17 is often the first aircraft to arrive with mobile hospitals, food, and water due to its ability to land where other big jets can’t.
- The “Moose”: US Air Force crews affectionately call the plane the “Moose,” supposedly because of the distinct groaning sound the relief valves make when the aircraft is being refueled on the ground.
- International Fleet: Beyond the US, the C-17 is the heavy-lift backbone for the UK (RAF), Australia, Canada, India, and the UAE, as well as the NATO Strategic Airlift Capability in Hungary.
