Amprius secures repeat $35 million purchase order from leading UAS manufacturer

Amprius Technologies, Inc., a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, today announced it has secured a purchase order totaling over $35 million for its SiCore cells from a leading Unmanned Aerial Systems (UAS) manufacturer. This follows a $15 million purchase order placed in February 2025, underscoring the accelerating adoption of Amprius’ high energy density batteries.

Produced at scale while maintaining breakthrough performance, Amprius’ SiCore cells are engineered for the rigorous demands of UAS missions, from take-off through sustained flight to landing. With industry-leading energy-to-power performance, SiCore extends flight times and mission ranges beyond the limits of conventional lithium-ion batteries, enabling next-generation aircraft to achieve the endurance required for critical operations.

“This follow-on order of more than $35 million from an existing customer highlights both the trust we’ve built with leading drone manufacturers and the strong momentum behind our revenue and market share growth,” said Dr. Kang Sun, CEO of Amprius Technologies. “As a leading supplier of silicon anode batteries, we are delivering the performance that enables our customers to meet their most demanding mission profiles. We believe the next phase of UAS growth will be powered by advanced high-performance batteries, and Amprius’ technology, products, and manufacturing capabilities uniquely position us to capture a growing share of this rapidly expanding market.”

Amprius supports large-scale orders through its global contract manufacturing network, which now exceeds 1.8 GWh of secured capacity. This includes a strategic agreement in South Korea, that supports adoption across aerospace, defense, and electric mobility markets.

The global unmanned systems market was valued at $26.6 billion in 2024 and is projected to reach $48.3 billion by 2030 at a 10.5% CAGR. Growth is primarily driven by defense, commercial, and industrial adoption, with UAS accounting for more than 57% of the market and North America contributing over 45% of global revenue in 2024. By combining industry-leading silicon anode batteries with established global manufacturing partners, we believe Amprius is solidifying its leadership in the future of electric aviation.
