About the Lockheed C-5 Galaxy

The Lockheed C5 Galaxy is the United States Air Force’s largest transport aircraft, capable of carrying a maximum payload of nearly 36 master pallets. It is powered by four General Electric CF6-80C2 turbofan engines, each producing over 230 kN thrust. 

Why was it developed and built?

The Lockheed C5 Galaxy was developed and built in response to the United States Air Force’s need for a large-capacity, long-range airlift aircraft. It was designed to transport cargo, including tanks and other military vehicles, at high speeds over long distances.

What purpose does it serve?

The Lockheed C5 Galaxy is used for various missions, including airlift support for combat operations. It also serves as a platform for transporting troops, supplies, and equipment. In addition, it is used for airdrop missions and as an aerial refueling platform.

About the Airbus A380

The Airbus A380 is among the world’s largest commercial passenger airplanes. It has a maximum take-off weight of 1,267,645 lbs at 98,000 feet and a wingspan of 261 feet (79.75 m). Regarding engines, it is powered by four Rolls-Royce Trent 900 turbofan engines, each producing over 78,000 pounds of thrust.

Why was it developed and built?

The Airbus A380 was developed and built to meet the increasing demand for air travel and to accommodate large numbers of passengers in a single flight. It was designed to be the most cost-efficient airliner, offering an impressive range of features and amenities, including spacious cabins with seating for up to 850 passengers.

What purpose does it serve?

Since its launch in 2007, the Airbus A380 has been used by airlines worldwide for international passenger travel. It also serves as a freighter aircraft, carrying cargo from one destination to another. In addition, the Airbus A380 can perform long-range missions, such as nonstop flights across the Atlantic or Pacific oceans.

How are the Lockheed C-5 Galaxy and Airbus A380 different?

Despite both being large, jet-powered airliners, they have several distinct differences. Let’s explore the seven major differences between these two giants of aviation!

#1 Size Difference

The first difference between these two planes is their size. The Lockheed C-5 Galaxy is one of the world’s largest military transport aircraft, with a wingspan of 222 feet and a length of 247 feet.

The Airbus A380 is even larger, with a wingspan of 262 feet and a length of 238 feet. This makes it clear that Lockheed C-5 Galaxy is smaller than its rival in wingspan and length.

#2 Cargo Capacity

The second difference between these two planes lies in their cargo capacity. 

The Lockheed C-5 Galaxy can carry up to 36 master pallets simultaneously, while the Airbus A380 has an impressive capacity of 185,000 lb. This means the Airbus A380 can transport more than the Lockheed C-5 Galaxy – an impressive feat for such a large plane!

#3 Engines & Power Output

Engine type and power output mark the third difference. The Lockheed C-5 Galaxy has four General Electric TF39 engines which produce 51,000 lbs each.

In contrast, the Airbus A380 has four Rolls-Royce Trent 900 turbofan engines, giving it an impressive 78,000 lbs thrust output! This makes it clear that the Airbus A380 has significantly more power than its rival.

#4 Speed & Range

The top speed of a fully loaded Lockheed C-5 Galaxy is around 532 mph, while its maximum range when carrying a full load is 4,260 km.

On the other hand, an empty Airbus A380 can reach speeds up to Mach 0.89 (945 km/h) while its maximum range when carrying a full load is 14,800 km – making it clear that this plane can go much farther on less fuel!
