CAMINUS to Manufacture Amprius Defense Battery Cells in Indianapolis
CAMINUS (formerly EnPower, rebranded October 1) announced October 5 a contract manufacturing agreement with Amprius Technologies (NYSE: AMPX) to produce Amprius-designed silicon-anode pouch cells at its 92,000-square-foot Indianapolis facility on Hague Road for aviation, defense, and uncrewed-systems customers. Qualification builds are underway now with volume production targeted for Q1 2027; CAMINUS's plant has self-reported capacity of over 500 MWh/year of electrode production and more than 2.4 million cells per year, and the deal follows Amprius's separate $75 million Department of War grant to convert a U.S. EV battery line for drone cell production.
- Impact
- CAMINUS is now Amprius's second named U.S. contract manufacturer after Nanotech Energy, which handles cylindrical cells for customers like L3Harris, this deal fills the pouch-cell format gap and positions Indianapolis as a secondary node in the defense-battery industrial base. The deal also races a regulatory deadline: NDAA Section 842 bars DoD battery procurement from foreign entities of concern starting January 1, 2028, but as of mid-September the DFARS language implementing that rule still hadn't been finalized, creating real ambiguity about what qualifies today versus after the rule is written.
- Watch
- Q1 2027 volume production ramp at the Hague Road facility, and whether DFARS is revised to formally define NDAA Section 842 compliance before then.
- For the huddle
With Indianapolis emerging as a defense-battery manufacturing node alongside the Southeast EV corridor, should we be exploring NDAA-compliant supply relationships before that domestic capacity gets fully booked?
