In a groundbreaking development for the renewable energy sector, RADIA has introduced the Windrunner, the largest cargo aircraft ever built, designed specifically to transport next-generation wind turbine blades. The aircraft aims to streamline delivery of ultra-long blades—some exceeding 100 meters in length—to remote wind farm locations previously inaccessible by road or sea.
The Windrunner, a fixed-wing aircraft with an enormous fuselage and specialized landing gear, will enable on-site delivery of full-length turbine components. This will support the installation of land-based turbines as tall as 300 meters, unlocking access to stronger, more consistent wind speeds at higher altitudes and significantly improving power output.
RADIA plans to begin Windrunner operations by the late 2020s, with test flights already in development. By eliminating key transportation bottlenecks, the company hopes to dramatically accelerate the deployment of high-capacity wind farms and contribute to global decarbonization goals.

Side-by-side comparison of the RADIA Windrunner with two of the world’s most notable heavy-lift aircraft: the Antonov An-225 Mriya (now destroyed in Ukraine) and the Airbus BelugaXL, focusing on size, payload, and purpose:
| Specification | RADIA Windrunner | Antonov An-225 Mriya | Airbus BelugaXL |
|---|---|---|---|
| Role | Wind turbine blade transport (specialized) | General heavy cargo transport (multi-purpose) | Oversized aircraft parts transport (Airbus) |
| Length | ~108 meters (354 ft) | 84 meters (275.6 ft) | 63.1 meters (207 ft) |
| Wingspan | >80 meters (262+ ft) | 88.4 meters (290 ft) | 60.3 meters (197.8 ft) |
| Height | >24 meters (78+ ft) | 18.1 meters (59.3 ft) | 18.9 meters (62 ft) |
| Max Payload Capacity | 80–100 metric tons (estimated) | 250 metric tons | 51 metric tons |
| Cargo Bay Length | 100+ meters (for wind blades) | 43 meters (141 ft) | 45.7 meters (150 ft) |
| Range (Fully Loaded) | 1,500–2,000 km (932–1,243 miles) | 4,000 km (2,485 miles) | ~4,000 km (2,500 miles) |
| Cruising Speed | ~800 km/h (497 mph) | 850 km/h (528 mph) | 780 km/h (485 mph) |
| Takeoff Requirement | STOL from remote or semi-prepared runways | Requires large paved runways | Operates from major airports |
| Unique Advantage | Purpose-built for ultra-long blades | Largest-ever cargo capacity (now retired) | Tailored for Airbus A350 fuselage transport |
| Operational Status | In development (target: late 2020s) | Retired (last aircraft destroyed in 2022) | In active service with Airbus |
Summary:
-
Windrunner is optimized not for maximum weight, but for extreme length cargo (like 100m+ wind turbine blades), which even the An-225 couldn’t carry internally.
-
An-225 was a brute-force heavy lifter, built for Cold War-era space shuttle transport and humanitarian mega-missions.
-
BelugaXL is Airbus’s modern workhorse for moving large but relatively lighter aircraft components within Europe.
Each aircraft excels in its niche, but Windrunner introduces a new transport category, purpose-built for the energy transition era.
