C5 Vs C17


In the world of military aircrafts, the C5 and C17 are two of the most impressive, powerful, and versatile planes. They play a vital role in the transportation of personnel and cargo, providing critical support to troops on the ground. Despite their similar functions, these aircrafts have several essential differences that set them apart.

C5 Galaxy

The C5 Galaxy is a strategic airlifter used by the United States Air Force. It can transport heavy cargo and equipment over long distances, making it an essential asset for moving troops, supplies, and equipment quickly and efficiently. This massive aircraft has a wingspan of 222 feet and can carry up to 270,000 pounds of cargo.

One of the most impressive features of the C5 Galaxy is its cargo bay. It measures 121 feet long, 13.5 feet high, and 19 feet wide, making it the largest cargo hold of any aircraft in the world. The cargo bay can accommodate up to 36 463L master pallets or a combination of pallets, vehicles, and people.

The C5 Galaxy is powered by four General Electric TF39 turbofan engines, each producing 43,000 pounds of thrust. These engines give the C5 Galaxy a maximum speed of 518 miles per hour and a range of over 5,500 miles when fully loaded. It can operate from short runways, including unpaved surfaces, making it versatile and adaptable to different environments.

C17 Globemaster III

The C17 Globemaster III is a versatile military transport aircraft that can perform a variety of missions. It is the newest strategic airlifter in the United States Air Force inventory and has a range of capabilities beyond those of the C5 Galaxy. The C17 can carry up to 170,900 pounds and has a cargo bay measuring 88 feet long, 18 feet wide, and 12 feet high.

The C17 Globemaster III is powered by four Pratt & Whitney F117-PW-100 turbofan engines, each producing 40,440 pounds of thrust. These engines give the C17 a maximum speed of 518 miles per hour and a range of over 2,400 miles when carrying full payload. The engines are designed to be efficient and reliable, requiring minimal maintenance and providing excellent fuel economy.

The C17 has several features that make it stand out from the C5 Galaxy, including short takeoff and landing capabilities, air dropping capabilities, and the ability to operate from semi-prepared runways. The aircraft can carry troops, vehicles, and supplies, making it a valuable asset in military operations worldwide. It can also be used to perform medical evacuations, humanitarian missions, and disaster relief efforts.

Comparing C5 and C17

The C5 Galaxy and C17 Globemaster III share several similarities, but they also have significant differences that separate them from one another. Here are some of the most notable differences:

Size

The C5 Galaxy is the larger of the two aircraft, measuring 247 feet long, 65 feet tall, and with a wingspan of 222 feet. The C17 Globemaster III, while still an impressive aircraft, is more compact, measuring 174 feet long, 55 feet tall, and with a wingspan of 169 feet. The C5 Galaxy’s size is a significant advantage in terms of the amount of cargo and personnel it can carry.

Payload

The C5 Galaxy can carry up to 270,000 pounds of cargo and up to 121 troops. The C17 Globemaster III, on the other hand, can carry up to 170,900 pounds of cargo or a combination of 102 paratroopers or 145 troops with palletized cargo.

Range

The C5 Galaxy has a maximum range of over 5,500 miles when fully loaded, while the C17 Globemaster III has a range of over 2,400 miles when fully loaded. The C17’s range is less than the C5’s due to its smaller fuel capacity.

Fuel Efficiency

The C17 Globemaster III is designed to be more fuel-efficient than the C5 Galaxy, with each of its Pratt & Whitney F117-PW-100 turbofan engines providing better fuel economy than the General Electric TF39 engines on the C5.
