When a satellite orbits, or an astronaut relies on emergency power thousands of miles above Earth, there is no margin for error. The power either delivers or it does not. For years, defense and aerospace engineers faced a fragmented reality, managing multiple vendors, reconciling incompatible chemistries, and accepting that no single American manufacturer could own the full spectrum from individual cell to complete power system. EaglePicher Technologies was founded to solve exactly that problem.
Established in 1843 and headquartered in Joplin, Missouri, EaglePicher entered the battery market in 1922 and secured its first special-purpose military battery contract in the 1940s. In 1958, its batteries flew aboard NASA’s Explorer 1, America’s first satellite, cementing the company’s place in the history of American space exploration. That moment defined an identity that the company has never abandoned. Today, EaglePicher holds approximately 85 percent market share in U.S. military missile battery supply, powers more than 600 satellites currently in orbit, and has logged over three billion cell hours in space without a single mission failure.
What distinguishes EaglePicher from other manufacturers is its end-to-end command of the power challenge. The company does not simply supply a battery and hand off responsibility. It delivers fully integrated energy solutions, covering raw electrochemistry, individual cells, complete battery packs, battery management systems, and energetic devices. A defense program manager or aerospace engineer works with one partner from initial concept through final production, eliminating the complexity and risk that come with multi-vendor dependency.
The product portfolio reflects that complete capability. Thermal batteries, for which EaglePicher holds the top position among U.S. manufacturers, deliver intense power in short bursts, making them ideal for missiles and Mars rover missions. Primary batteries serve single-activation, mission-critical applications where failure is not a permissible outcome. Secondary rechargeable batteries, built around advanced lithium-ion chemistry, support sustained aerospace missions and aviation platforms, including the B-2 Bomber and Global Hawk UAV. Energetic devices and custom battery packaging complete an offering that very few manufacturers anywhere in the world can provide under one roof.
The technology infrastructure supporting these products is equally formidable. EaglePicher’s Battery Management Systems range from low-power portable configurations to megawatt-class, 1,000-volt energy storage architectures. These systems deliver real-time monitoring of state of charge, state of health, and fault conditions, supported by radiation-hardened processors and redundant dual-core designs built for environments where failure carries catastrophic consequences. The company’s Lithium-Ion Center of Excellence, established in 2018, continues advancing energy density, safety, and cycle life for next-generation defense and aviation programs.
We exist to deliver power that never fails because in defense and space, the cost of failure is one no mission can afford. — David Treadwell, CEO
The performance record stands on its own. EaglePicher’s nickel-hydrogen batteries aboard the Hubble Space Telescope operated for 19 years in orbit, surpassing their projected 5-year design life by 14 years. When an oxygen tank failure crippled Apollo 13 in 1970, EaglePicher’s silver-zinc batteries powered the life support and guidance systems that brought three astronauts safely home. These are not promotional claims; they are verified operational records written into the history of American defense and space achievement.
All facilities in Joplin, East Greenwich, and Southbridge maintain ISO 9001:2015 and AS9100D certifications, meeting quality standards set by the Department of Defense, NASA, and the FAA. In 2024, Northrop Grumman presented EaglePicher with its Supplier Excellence Award. The company’s acquisition by Tuthill Corporation in 2023 has further strengthened its investment in capacity, talent, and long-term research.
