An extraordinary project that merges the worlds of aviation and renewable energy is making headlines: WindRunner. Even though it has not yet been built, this giant aircraft is already a strong contender for the title of “the world’s largest plane.” What makes it even more intriguing is that it’s not backed by industry giants like Airbus, Boeing, or Lockheed Martin, but by Radia—a startup that has never built an aircraft before.
Founded in 2016 by serial entrepreneur and aerospace engineer Mark Lundstrom, Radia is leading this ambitious initiative to make it possible to deliver massive wind turbine blades to land-based wind farms.
The Biggest Obstacle to Wind Energy: Logistics
One of the main limiting factors for onshore wind energy is the difficulty of transporting enormous turbine blades. Offshore turbines can have blades longer than 100 metres, while onshore turbines are often limited to around 70 metres. This size difference significantly reduces efficiency and energy output.
Lundstrom’s goal is to solve this logistical challenge to make onshore wind energy cheaper and more powerful. “If we can pull this off, it would dramatically improve the economic viability of wind farms not just in the US, but globally,” he says. The project has been named “GigaWind.”
What Will WindRunner Be Like?
Radia’s WindRunner is set to become the largest and most powerful cargo aircraft ever designed. Its mission: to deliver wind turbine blades directly to wind farm sites. It’s being designed to take off and land not only at conventional airports but also on shorter and semi-prepared runways near wind farm locations.
The cargo bay of this enormous aircraft is expected to surpass even the legendary capacity of the six-engine Antonov An-225 Mriya. However, unlike the Mriya, WindRunner is not intended to remain a one-off prototype.
$150 Million in Funding and a High-Profile Advisory Team
Radia, headquartered in Colorado, has raised more than $150 million to date. The project has attracted top-level advisors from the aviation, energy, and defence sectors. According to CEO Mark Lundstrom, this enormous plane “will address a massive global need that has been overlooked until now.”
Target: One Million “Super Turbines” by 2050
Lundstrom estimates that with logistics solutions like WindRunner, the number of onshore super turbines worldwide could exceed one million by 2050. That could be a game-changer for carbon-free energy production and global climate goals.
A New Hope After the Antonov Mriya
WindRunner also highlights the renewed demand for massive cargo aircraft, especially following the destruction of the Antonov An-225 Mriya during Russia’s 2022 invasion of Ukraine. Since then, there has been a major gap in the ability to transport large-scale equipment—from disaster relief to energy infrastructure.
