When it comes to large military transport aircraft, few compare to the impressive C-17 Globemaster. Developed by McDonnell Douglas (now part of Boeing) in the 1980s, the C-17 is a four-engine jet with a massive cargo bay capable of transporting up to 170,900 pounds of cargo or over 100 soldiers.
So just how big is the C-17? Let’s take a closer look at its size comparison and explore some FAQs about this incredible aircraft.
When fully loaded with cargo, the C-17 measures 174 feet long, 55 feet tall, and has a wingspan of 169 feet. Its cargo bay measures 88 feet long, 18 feet wide, and 12 feet tall. For comparison, that’s roughly the size of a three-car garage.
But it’s not just the C-17’s size that’s impressive. It’s also incredibly heavy, with a maximum takeoff weight of 585,000 pounds. To put that into perspective, that’s about the same weight as 30 elephants or 176 cars.
To make such a weight possible, the C-17 is powered by four Pratt & Whitney F117-PW-100 turbofan engines, each capable of producing 40,440 pounds of thrust. These engines give the C-17 a top speed of 590 miles per hour and a range of about 4,000 nautical miles.
So how does the C-17 compare to other military transport aircraft? Let’s take a look at a few:
