SandboxAQ Flies AQNav Magnetic Navigation on Northrop Grumman's Lumberjack, the First Reported MagNav Test on an Attritable One-Way-Attack Drone

On September 9, 2026, SandboxAQ and Northrop Grumman reported the first flight test of magnetic navigation on an attritable one-way-attack drone, with AQNav installed into Lumberjack's existing systems in under an hour. We read what the test establishes for GPS-denied operations, set it beside Q-CTRL's Coral Sea gravimetric trial and Saab's quantum-timed radar network, and lay out what still separates a flight campaign from the alternative PNT capability a program office can rely on.
