Amprius Technologies, Inc., a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, today announced that Nordic Wing, a leading European drone manufacturer, has selected Amprius’ high-energy-density SiCore® cells to power ASTERO ISR, a fixed-wing unmanned aerial vehicle (UAV) designed for advanced intelligence, surveillance, and reconnaissance (ISR) missions in defense operations.

The selection follows a successful evaluation and qualification process, where Amprius’ SiCore cells delivered a 90% increase in flight endurance in Nordic Wing’s ASTERO ISR compared to conventional graphite cells. This dramatic increase extends mission time to up to four hours without adding weight and improves the UAV’s surveillance and mapping capabilities.

“Amprius’ batteries have fundamentally changed how our drones operate in the field,” said Jonas Dyhr, founder of Nordic Wing. “With a significant increase in flight time, our drones can stay airborne longer, cover more ground, and deliver real-time intelligence without interruptions. This enhanced endurance doesn’t just improve performance; it redefines what’s possible in every mission and can mean the difference between success and failure.”

In modern defense operations, endurance isn’t just a performance metric; it’s mission critical. Amprius’ SiCore batteries provide the consistent power needed to operate in GPS-denied and electronically contested environments, where drones can’t afford to fail. That reliability enables longer surveillance windows, deeper situational awareness, and fewer compromises in the field, giving operators a clear tactical advantage when it matters most.

“Energy is rapidly becoming a critical factor in drone operations,” said Tom Stepien, president of Amprius Technologies. “As mission requirements grow more complex, the need for lightweight, long-lasting, and dependable battery solutions continues to rise. Amprius is proud to be at the forefront of this evolution, delivering next-generation batteries that meet the dynamic needs of our defense partners like Nordic Wing.”

This partnership highlights Amprius’ continued execution in scaling its high-performance silicon anode batteries across key electric mobility sectors. With commercially available cells powering applications in unmanned aerial systems, high-altitude platforms, and electric mobility, Amprius is uniquely positioned to deliver the performance, reliability, and scale required for the next generation of aviation and defense systems.
