The U.S. Army Combat Capabilities Development Command (DEVCOM) Army Research Laboratory (ARL) is advancing atomic clock technology and electric field sensors for future battlefield applications. The goal is to create compact, high-performance atomic clocks capable of functioning without GPS.

Current chip-scale atomic clocks lack the performance needed for extended missions in GPS-denied environments. ARL has initiated the Low-Cost Chip-Scale Atomic Clock program to develop these devices affordably. Collaboration with other military services and industry partners is essential for enhancing these quantum capabilities.
