Expeditionary power

Power generation and storage for forces away from fixed grids.

Assessment

Case for · why it matters

Drones, sensors, counter-UAS and networked command posts have made electrical power a constraint on combat units, and oversized diesel generators waste fuel and expose positions through noise and heat. Army brigade experiments with battery modules, inverters and solar arrays let teams run for days without generators.

Case against · the skeptic’s view

The Army's acquisition chief for maneuver says simply adding batteries overloads soldiers, and its CTO notes liquid fuel is still the most power-dense way to move energy. Battery-based microgrids also add lithium-ion supply-chain exposure, and most new systems are still in exercises and prototype buys.

Products2

Amphora

Chariot Defense

Family of transportable battery storage and power distribution systems (Amphora 24 at 24 VDC and Amphora 400 at 400 VDC per the company) that draw on generators, vehicles, grid and renewables and form a software-controlled tactical microgrid. Used at NTC rotation 26-02; to be delivered to Army brigades under DIU PRISM.

Limited fielding

Dispatch dock

Dispatch

Mobile, self-leveling drone dock for autonomous launch, recovery and charging of short-range reconnaissance drones such as the Skydio X10D; developed under an Army CRADA.

Prototype

Inputs it depends on1

Criticality is how much a shortage would constrain production; open an input for producers, concentration and trade controls.
