C 5 Galaxy Vs C 17 Globemaster


When it comes to military transport planes, the C-5 Galaxy and the C-17 Globemaster are two of the most powerful aircraft in the sky. These two giants of the air are used to move large quantities of supplies, equipment, and people, between military bases and on humanitarian missions around the world. In this article, we will compare the C-5 Galaxy and the C-17 Globemaster, looking at their specifications, capabilities, and performance to determine which is the better plane for the job.


The C-5 Galaxy is the largest transport plane in the U.S Air Force inventory. It has a maximum payload capacity of 270,000 pounds and can carry up to 31 oversize cargo pallets or 36 standard cargo pallets. The C-5 has a wingspan of 222.9 feet and a length of 247.1 feet. It is powered by four General Electric TF39 engines, which allow it to fly at a maximum speed of 518 miles per hour.

The C-17 Globemaster is a medium-sized transport plane with a payload capacity of 170,900 pounds. It can carry up to 18 cargo pallets or 102 paratroopers. The C-17 has a wingspan of 169.8 feet and a length of 174 feet. It is powered by four Pratt & Whitney F117-PW-100 turbofan engines, which give it a maximum speed of 590 miles per hour.


The C-5 Galaxy’s main role is to transport outsized cargo such as tanks, helicopters, and other military equipment. It can also carry personnel, but this is not the primary purpose of the aircraft. The C-5 has the ability to operate in any climate or terrain and has been used extensively in support of military operations in Iraq and Afghanistan.

The C-17 Globemaster is a versatile aircraft that can be used for a wide range of missions. It is primarily used for airlifting cargo and personnel, but it can also be used for airdropping troops and cargo, and as an air ambulance. The C-17 is highly maneuverable, which makes it well-suited for operating in tight spaces like small airfields.


The C-5 Galaxy has a maximum range of approximately 8,000 miles and can carry a large amount of fuel, which allows it to stay in the air for an extended period of time. The C-5 is capable of flying at a maximum altitude of 34,000 feet, which allows it to avoid most of the weather-related turbulence that can be encountered at lower altitudes.

The C-17 Globemaster has a range of approximately 4,000 miles, which is less than that of the C-5. However, the C-17 is more fuel-efficient than the C-5, which means it can carry more cargo over a shorter distance. The C-17 can fly at a maximum altitude of 45,000 feet, which allows it to fly over most weather systems with ease.


In conclusion, both the C-5 Galaxy and the C-17 Globemaster are excellent transport planes that are essential to military operations around the world. While the C-5 is larger and can carry more cargo, the C-17 is more versatile and can perform a wider variety of missions. Ultimately, the choice of aircraft will depend on the specific needs of the mission at hand.
