In the face of war, destruction, and unprecedented challenges, Ukraine’s aviation industry has once again proven its strength and resilience. The successful airlifter restoration of a stranded An-124-100 Ruslan aircraft, UR-82073, marks a historic return to the skies for Antonov Airlines. This heavy airlifter, grounded in Kyiv due to Russia’s full-scale invasion in 2022, has been reassembled, upgraded, and returned to operation—now flying from Leipzig, Germany.
This article explores the entire journey of this iconic Antonov cargo aircraft, including its technical specifications, restoration efforts, strategic importance, and modernization efforts. Whether for oversized cargo transport or military logistics, the An-124’s return is a proud moment for Ukrainian aircraft engineering.
A Soviet-Era Giant: An-124-100 Ruslan Overview
Developed in the 1980s, the An-124-100 Ruslan remains one of the most capable cargo aircraft in the world. Designed during the Soviet Union’s peak aerospace era, it was tailored to transport exceptionally large and heavy cargo loads globally.
Key Features of the An-124-100 Ruslan:
Maximum takeoff weight: 405,000 kg
Cargo capacity: 150,000 kg
Maximum range (with full load): 5,400 km
Nose and rear cargo doors for loading/unloading
Four Progress D-18T turbofan engines
Crew: 6 (including navigator and engineer)
Can operate on unpaved or damaged runways
This aircraft’s unique ability to carry cargo that cannot fit into any other plane made it a vital asset for humanitarian aid, military deployment, and commercial oversized cargo transport.
Why UR-82073 Was Grounded
In 2021, aircraft UR-82073 was sent to Kyiv for a major overhaul. The objective was to replace all Russian-origin systems with Ukrainian and Western-made components—part of a wider national initiative to reduce dependency on Russian aerospace manufacturing. The process included aircraft disassembly and upgrade, affecting systems like:
Avionics
Hydraulic systems
Communication modules
Navigation equipment
However, when Russia launched its invasion in February 2022, the aircraft was caught in Kyiv mid-upgrade, in a state of complete disassembly.
Restoration Timeline of UR-82073

Despite the chaos, Ukrainian engineers completed the airlifter restoration by June 2025, using replacement parts sourced from Europe and the US.
Aircraft Disassembly and Upgrade: A Technical Feat
Reassembling the massive An-124-100 Ruslan was no small task. Given the aircraft’s complexity and the war-torn environment, Ukrainian engineers had to overcome enormous hurdles:
Main Technical Upgrades Included:
Full fuselage structural integrity assessment
Upgraded Western avionics and flight computers
Engine system recalibration
Replacement of hydraulics and fuel systems
New navigation and communication modules
This project wasn’t just about making the plane fly again—it was about transforming it into a modern aircraft capable of meeting EU safety and aviation standards.
Strategic Importance of the An-124 in Modern Aviation
With five An-124s currently active, Antonov Airlines now operates out of Leipzig, Germany. The restored UR-82073 will contribute to both military and commercial logistics operations.
Military Use Cases:
Transporting tanks, drones, and defense systems
Airdrop support for remote operations
Resupplying frontline troops and bases
Commercial Use Cases:
Global transport of turbines and mining equipment
Delivery of generators and emergency machinery
Relief cargo for disaster-hit regions
In both sectors, the aircraft’s value lies in its unmatched payload capacity and operational range.
Lessons from the Battle of Hostomel
The Battle of Hostomel Airport (Feb 24–25, 2022) was a major loss for Ukraine’s aviation sector. Antonov Airlines lost three aircraft:
An-26 turboprop (logistics plane)
An-74 (twin-engine cargo jet)
An-225 Mriya – the world’s largest aircraft
The loss of the An-225 Mriya was devastating globally, symbolizing the destruction of aerospace heritage. However, the UR-82073 restoration shows that Ukraine is not giving up—it’s rebuilding smarter, stronger, and with modern capabilities.
Soviet-Era Aircraft Modernization: The Future of Antonov
One of Ukraine’s long-term goals is to modernize its remaining Soviet-era aircraft with Western technology. The UR-82073 is now a working prototype for this national strategy.
Ongoing Modernization Objectives:
Replace Russian parts with NATO-compatible systems
Enhance environmental compliance
Improve safety with digital cockpit upgrades
Expand range through fuel efficiency improvements
Add satellite-linked navigation (GNSS) systems
The modernization of UR-82073 sets the standard for future upgrades, including potentially rebuilding a new An-225 in the years to come.
Symbol of Ukrainian Resilience
Antonov Airlines called the restored An-124 not just a technical win, but a “symbol of resilience and professionalism.” In a time of national crisis, Ukrainian engineers, mechanics, and flight crews have turned a disassembled aircraft into a modern asset.
Why This Restoration Matters Globally:
Restores a rare, essential aircraft for global logistics
Demonstrates Ukrainian industrial capabilities
Reinforces NATO and EU support infrastructure
Boosts morale in the aviation and defense communities
Summary of Key Achievements
Here’s a recap of the top milestones in the UR-82073 restoration:
✅ Aircraft grounded in Kyiv during Russian invasion
✅ Complete upgrade with non-Russian parts
✅ Fully operational after 3 years of downtime
✅ Rejoined active fleet in July 2025
✅ Base of operations shifted to Leipzig, Germany
✅ Aircraft now meets updated safety and navigation standards
Conclusion
The return of the An-124-100 Ruslan UR-82073 is more than just an aviation success—it’s a powerful reflection of national perseverance and innovation. From being stranded in Kyiv in pieces to flying missions out of Leipzig, the transformation of this aircraft is symbolic of Ukraine’s broader journey through war and recovery.
As Ukraine continues to modernize its aviation industry and reduce reliance on Russian technology, projects like this will become more common. The Ruslan’s revival is a blueprint for how engineering, vision, and determination can overcome even the gravest challenges. It is not just a plane returning to service—it is a nation’s spirit taking flight again.
