- The Antonov An-124 Ruslan was built in the 1980s as a strategic military airlifter for the USSR.
- Both Ukraine and Russia have used the giant quad-engine freighter in the ongoing war effort.
- Two engines from Ukraine's destroyed An-225 jet have been salvaged and sent to its An-124 fleet.
The world's largest airplane, the Antonov An-225 "Myria", was destroyed in February 2022 after Russia's attack on Hostomel Airport near Ukraine's capital of Kyiv.
Ukraine has been busy salvaging what it can of the jet since March 2023, with three engines actually being repaired and sent to the fleet of An-225's sister jet: the Antonov An-124 Ruslan, a heavy-lift plane operated mostly by Russian and Ukrainian carriers.
Take a look at the giant aircraft, which has faced serious headwinds since Moscow's invasion of Ukraine.
Although Ukraine was still part of the USSR when the An-124 was built, the Antonov Company — then known as the Antonov Design Bureau — remained a part of Ukraine after the country's independence in 1991.
The original Ruslan was built for military transport, running long-range delivery missions and air-dropping heavy cargo equipment, as well as troops.
The AN-124-100M-150 commercial freighter is the latest version of the Ruslan airlifter, having been modified to increase the payload capacity to a little more than 330,000 pounds and fly nearly 400 miles farther than its predecessor. Its maximum takeoff weight is about 886,000 pounds.
Its current day commercial use has seen it carry things like oil drilling machines and aircraft engines.
The An-124 was actually the precursor to the An-225, which was built at the request of the USSR to carry its Busan Space Shuttle.
A quick turnaround time required by the Soviets meant it was more efficient to just create a larger version of the already-proven Ruslan.
The nose-loading door is only featured on a few other mammoth cargo planes, like the Boeing 747 freighter, the US Air Force's Lockheed C-5M Super Galaxy, and Airbus' Beluga transporter.
In 1993, the AN-124-100 carried a Siemens generator weighing 124 tonnes from Frankfurt, Germany to New Delhi, India, making it at the time the heaviest piece single piece of equipment ever airlifted.
A year later, General Motors tapped Antonov to fly a 109-tonne locomotive from Ontario, Canada, to Dublin, Ireland. The journey took 12 hours, including two refueling stops, and set a record for transporting the "heaviest cargo (plus equipment) of 146 tons."
Antonov Company subsidiary Antonov Airlines currently operates five An-124 aircraft out of Germany on behalf of NATO and the Ukrainian government. The jets are also flying on some humanitarian missions.
According to Planespotters, the Kremlin has 21 An-124s across cargo carrier Volga-Dnepr and the Russian Air Force. Several of which, however, have been confiscated after Western nations imposed sanctions against Moscow.
Ukraine's An-124 stands about 68 feet tall and 227 feet long with a 240-foot wingspan. Its 150-tonne payload is greater than the 140 tonnes of weight the C-5M is capable of carrying.
A handful of the world's fleet of An-124s are either damaged or seized, even forcing Antonov to relocate from Ukraine to Germany after the destruction of Hostomel airport.
"As a result of the Russian attack and occupation of the airfield, significant damage has been caused to its infrastructure, office buildings, hangars, as well as the destruction of the AN-74T, AN-26-100, and AN-225," the company confirmed in May 2022, Simple Flying reported.
Another of the five surviving An-124s actually narrowly avoided destruction when it took off from Hostomel airport just one hour before Russia's attack, Aviacionline reported.
According to Planespotters, eight of Volga-Dnepr's 10 Ruslans are parked. Four of these are stuck abroad including one in Canada and three in Germany, Aerotime Hub reported.
The solo An-124 currently sitting in Canada was confiscated following Russia's invasion of Ukraine and subsequent sanctions against the Kremlin.
Canada is now set to hand the An-124 back over the Ukraine to help with its continued war effort against Russia.
Over the months, the An-124 has been used to deliver military cargo like the armored vehicles moved from Australia to the Ukrainian army in May 2022.
Ukrainian journalist and photographer Igor Lesiv, who visited the destroyed An-225 in August, told Insider that three of the jet's six engines could be saved — two of which went to the An-124 fleet.
"D-18T engines were always rearranged between AN-225 and AN-124, so they are now used on Ruslans," he said.
Ukrainian President Volodymyr Zelensky and the Antonov Company have announced commitments to rebuilding the legendary Mriya — a feat the country estimated in November to cost about $500 million.
