These colossal machines are not merely bigger planes; they are engineering marvels designed to move extraordinary cargo across vast distances. From helicopters and industrial equipment to humanitarian aid and even space shuttle components, these giants of the sky play a crucial role in our interconnected world. Interestingly, many of these behemoths have their roots in the Cold War era, proving that necessity and innovation often go hand in hand. Let’s delve into the world of these aerial leviathans and explore some of the most impressive examples of world’s largest transport aircraft.
Antonov An-225 Mriya: The Undisputed King
Length: 84m
Maximum capacity: over 250,000 kg
The Antonov An-225 Mriya, meaning “Dream” in Ukrainian, was truly in a league of its own. This aircraft held the world record for the largest single-item payload ever airlifted, a staggering 418,834 pounds. It also boasted the record for the heaviest total airlifted payload at 559,577 pounds, or 280 tonnes. Beyond sheer weight, the An-225 was designed to carry exceptionally large loads, a necessity driven by its original purpose: transporting the Soviet Buran space shuttle. Imagine carrying a space shuttle on your back! During its testing phase in 1989, this titan etched its name in aviation history by setting 106 world records related to weight, distance, and altitude.
Conceived in the 1980s by the Antonov Design Bureau in the Ukrainian SSR (part of the Soviet Union), the An-225 was a strategic airlift cargo aircraft unlike any other. It remains the only aircraft ever built powered by six turbofan engines. Furthermore, it is the heaviest aircraft ever constructed, with a maximum takeoff weight of 640 tonnes (1,410,000 lbs). Adding to its imposing presence, the An-225 also possessed the largest wingspan of any operational aircraft. Sadly, the only completed An-225 was destroyed in 2022 during the conflict in Ukraine, marking the end of an era for this unparalleled aircraft.

Before the Beluga XL, there was the original Airbus Beluga, officially designated the Airbus A300-600ST. Introduced in 1995, the Beluga was designed to replace the older Super Guppy aircraft in Airbus’s component transport operations. It is essentially a modified version of the standard A300-600 wide-body airliner, re-engineered to carry aircraft parts and other oversized cargo.
The BelugaST’s maiden flight took place in September 1994, and it received airworthiness certification in October 1995. Currently, five Beluga aircraft are in operation, all based on modified Airbus A300-600 jets. The modification process involved cutting the top section of the standard A300 fuselage and adding a larger, bubble-like fuselage section to the airframe, giving the Beluga its distinctive humpback shape. The cockpit was also lowered, allowing for front-loading and unloading of the cargo hold, a crucial feature for efficient operations. The result was a capacious cargo hold with a volume of 1,400 cubic meters, a space large enough to accommodate 671 people, 36 cars, or even, humorously, seven elephants. The Airbus Beluga ST served as a vital link in Airbus’s supply chain for many years and paved the way for its larger and more capable successor, the Beluga XL.
Antonov An-22 Antei: The Turboprop Titan
Length: approx 57.92 m (dependent on nose config.)
