WindRunner Aircraft Eyed as World's Largest, Capable of Carrying Six Helicopters

The WindRunner aircraft is poised to become the largest cargo plane ever developed, provided it progresses to production. Its design significantly surpasses most current military cargo aircraft, specifically engineered to transport extremely large payloads that have historically been challenging to move by air.

According to its developers, the WindRunner concept features a length of approximately 109 meters and a wingspan of 84 meters. Its cargo bay extends to 106 meters, offering an internal volume exceeding 6,800 cubic meters. This capacity is substantial enough to accommodate up to six fully assembled CH-47 Chinook helicopters or multiple C-130J Super Hercules airframes in a single flight.

Comparatively, the WindRunner's cargo volume is estimated to be about seven times larger than that of the C-5 Galaxy and roughly 12 times that of the C-17 Globemaster III. This emphasis on sheer volume is its primary advantage. However, its maximum payload capacity is projected at around 72.5 tons, which is less than the legendary Antonov An-225 Mriya from Ukraine.

Therefore, the WindRunner's focus is not on maximum weight but on transporting oversized items that are difficult to fit into conventional cargo planes, even if their weight is not extreme. A key feature is its ability to take off from relatively short runways, requiring only about 1,800 meters. This capability would enable logistics distribution to remote locations, including military bases, wind energy project sites, mining areas, and disaster-stricken regions needing rapid equipment delivery.
