The Pentagon has committed up to $200 million to field quantum navigation and timing sensors, converting a June presidential order into a concrete program with a 2028 deadline.
The stakes are not theoretical. GPS signals have already failed in the field: jamming suspected to originate in Russia forced the aircraft carrying European Commission President Ursula von der Leyen to land using paper maps last year, one of a string of incidents that has pushed commercial pilots in the Baltic states to rely on backup navigation routinely.
On June 22, President Trump signed Executive Order 14411, directing the Department of War, the Pentagon’s other name under the order, to identify at least three next generation quantum sensor projects within 60 days and field them by September 30, 2028. Roughly a week ago, the Defense Innovation Unit answered that mandate directly, launching what it calls Project Farseer and committing up to $200 million over the next year to move mature quantum sensing and timing technology from testing into use by the Joint Force.
The clearest evidence the approach already works comes from a separate DARPA effort. Under the Defense Advanced Research Projects Agency’s Robust Quantum Sensors program, the company Q-CTRL tested a system called Ironstone Opal that tracks motion using atom interferometry, a technique that needs no external signal and cannot be jammed or spoofed. In flight testing, the system achieved up to 111 times greater positioning accuracy than a high end classical inertial navigation system when GPS was unavailable, a demonstrated result rather than a laboratory projection.
Adm. Christopher Grady, vice chairman of the Joint Chiefs of Staff, has been blunt about why the Pentagon is moving quickly. Relying solely on satellite based positioning, he told defense industry executives, means “we may be in trouble” in contested environments where adversaries can jam or spoof GPS.
DARPA is also pursuing a separate effort called Perrseus, aimed at shrinking laboratory scale quantum sensors down to chip sized devices that could eventually navigate missiles, drones and submarines without any satellite signal at all. Full scale, code breaking quantum computers remain years from reality by most expert estimates, but sensing is the branch of the same physics already moving from the lab onto military platforms.
