Radia plans to showcase its WindRunner aircraft at the Singapore Air Show next month.
The Boulder, Colorado-based aerospace company said WindRunner is intended to address growing limitations in existing air cargo systems, as global supply chains increasingly depend on oversized, high-value components that often exceed aircraft volume constraints long before reaching weight limits.
The constraints frequently force cargo to be disassembled and routed through multiple modes of transportation, including ships and trucks, adding time, cost, and logistical complexity.
Radia said WindRunner is designed to move cargo previously considered too large to fly, including widebody fuselage sections, the largest jet engines ever built, power transformers up to 70 tonnes, ultra-long wind turbine blades exceeding 100 meters, and next-generation space hardware such as large rockets, satellites, and launch systems.
The aircraft prioritizes internal volume over payload weight, with more than 6,800 cubic meters of usable cargo space, which is 10x bigger than a 777's volume. It also supports roll-on, roll-off transport of fully assembled cargo. The company says it's designed to operate from semi-prepared or unpaved runways as short as 1800 meters.
Radia said it does not plan to sell WindRunner jets directly. Instead, the company intends to offer the aircraft through a transport-as-a-service model, providing capacity to commercial operators, governments, and humanitarian organizations. Radia said the platform is designed to support a wide range of missions, including industrial project cargo, aerospace transport, energy infrastructure delivery, humanitarian relief, and logistics into remote or infrastructure-constrained regions.
The company is also working with established cargo operators to align WindRunner's design with real-world operational requirements. In 2025, Radia announced a collaboration with Maximus Air to explore the aircraft's potential for outsized cargo missions.
Radia said WindRunner's point-to-point capability is expected to reduce handling steps, reliance on ports and roads, and overall project complexity.
WindRunner is currently in detailed design and supplier integration, with first flight targeted by the end of the decade.
