Antonov AN-124 vs. Lockheed C-5 Galaxy

The Antonov AN-124 Ruslan, a heavy-lift cargo aircraft, is one of the largest of its kind in the world. Developed by the Antonov Design Bureau in Ukraine, the AN-124 has played a critical role in transporting oversized and heavy cargo globally.

Production History: Initiated in the 1970s to augment the cargo-carrying capacity of the Soviet Air Forces, the design work on the AN-124 began at the Antonov Design Bureau under the leadership of Viktor Tolmachev. The aircraft's development was part of the Soviet Union's response to strategic airlift challenges, with the maiden flight taking place on December 24, 1982. Following the dissolution of the Soviet Union, the AN-124 gained civil certification on December 30, 1992. Political tensions between Russia and Ukraine in the 2010s impacted the continuation of its production.

Design Features: The AN-124 is distinguished by its large size, with a length of 69.1 meters, a height of 21.08 meters, and a wingspan of 73.3 meters. The aircraft's design includes a double-deck configuration, with a cockpit above the cargo area. It is equipped with a nose cargo door and a rear cargo ramp for easy loading and unloading. The AN-124 features four Ivchenko Progress D-18T turbofan engines, each providing substantial thrust, allowing for heavy cargo transportation. The aircraft has a distinctive 32-wheel landing gear system, designed for operation on rough terrain and unprepared airstrips.

Operational History: Since its introduction, the AN-124 has been utilized for a variety of military, humanitarian, and commercial cargo transport missions. Its capability to transport large and heavy cargoes, including military vehicles, industrial equipment, and other oversized items, has made it a valuable asset for various logistical operations across the globe.

Similar Freighter Models: The AN-124 is comparable in size and role to other large cargo aircraft such as the Lockheed C-5 Galaxy. However, it differs in its specific design features, such as its nose loading door and the arrangement of its engines and landing gear.

The Lockheed C-5 Galaxy is a large military transport aircraft developed by the Lockheed Corporation, now Lockheed Martin. The C-5 distinguishes itself by its sheer size and payload capacity, designed to transport a wide range of military equipment, including oversized vehicles and machinery.

Production History: Development of the Lockheed C-5 Galaxy began in the 1960s to replace the Douglas C-133 Cargomaster and to complement the Lockheed C-141 Starlifters. The United States Army desired a transport aircraft that could carry a wide array of outsized equipment. After a rigorous selection process, Lockheed's design, characterized by a T-tail and a unique cockpit position above the cargo area, was chosen in 1965. The first C-5A Galaxy was rolled out in 1968. The program, however, faced several challenges, including technical problems, weight issues, and cost overruns, leading to congressional investigations. Despite these hurdles, the C-5 Galaxy emerged as a key asset in strategic airlift capabilities​​​​.

Design Features: The C-5 Galaxy stands out with its four General Electric TF39-GE-1C turbofan engines, providing a significant thrust and efficiency. Its design includes a high-set wing with a 25-degree sweep and a distinctive T-tail. The aircraft is equipped with forward and rear cargo loading assemblies and a visor-type upward-hinged nose. The upper deck can accommodate a crew of six, a relief crew, and passengers, with provisions like bunk rooms, galleys, and lavatories. The cargo compartment is vast, capable of carrying a range of military hardware, including tanks, helicopters, and large numbers of troops. The landing gear system is unique, featuring a "kneeling" capability to facilitate cargo loading. The C-5 also has inflight refueling capabilities, extending its operational range significantly​​.

Operational History: Since its introduction, the C-5 Galaxy has been a critical component of U.S. military logistics, capable of transporting heavy and outsized military equipment globally. It played a vital role in operations such as Desert Shield and Desert Storm, where despite being only 12% of the airlift fleet, it carried 44% of the cargo. The Galaxy's capacity for strategic airlift has proven invaluable in numerous military and humanitarian operations, making it a cornerstone of the U.S. Air Force's airlift capability.

Similar Freighter Models: The Lockheed C-5 Galaxy is often mentioned alongside the Russian Antonov An-124. The C-5 was the largest aircraft in the world until the introduction of the An-124 in 1982. Compared to other US military aircraft, the C-5 Galaxy is significantly bigger than the C-17 Globemaster III, C-130 Hercules, and C-141 Starlifter.
