TOULOUSE, France--(BUSINESS WIRE)--Regulatory News:

Latecoere (Paris:LAT), a Tier-1 partner to aerospace manufacturers, has been selected by Radia to support the development of the Electrical Wiring Interconnection System (EWIS) for WindRunner, the world's largest cargo aircraft.

WindRunner is designed to enable direct transport of oversized cargo across defense, energy, commercial, aerospace, and humanitarian missions without reliance on specialized infrastructure. Dual use aerospace company Radia is headquartered in Boulder, Colorado and Rome, Italy, with a growing global partner and supplier network.

Latecoere brings its extensive expertise in aircraft electrical systems across commercial and defense aerospace programs. The collaboration will support development of the aircraft's electrical architecture and help establish a robust, scalable systems foundation capable of supporting WindRunner's unprecedented size and operational requirements. The team will support the program from its design office in Toulouse, France, as well as on-site with the customer, ensuring close collaboration and the successful delivery of key program milestones.

"The WindRunner's Electrical Wiring Interconnection System (EWIS) is the largest nervous system of any aircraft ever built, and it has to perform flawlessly from day one," said Mark Lemke, Vice President Aircraft Development and Supply Chain at Radia. "Latecoere's proven, certified EWIS expertise across commercial and defense programs is exactly what a platform of this scale requires."

"WindRunner represents one of the most ambitious aerospace development programs underway today," said Sam Marnick, President Americas of Latecoere. "We are pleased to collaborate with Radia and contribute our expertise in aircraft electrical systems integration to support the development of this groundbreaking aircraft. The scale and complexity of WindRunner create exciting opportunities for innovation and collaboration across the aerospace industry."

As the program progresses, Radia continues to selectively add partners whose capabilities accelerate development while strengthening the long-term industrial foundation required to support WindRunner's missions worldwide.
