Palo Alto, Calif. – September 15, 2026 -- SandboxAQ has completed what it calls the world's first reported test of a magnetic navigation (MagNav) system on an attritable drone platform, integrating its AQNav software into Northrop Grumman's Lumberjack Group 3 unmanned aircraft system.

The flight demonstration also represents the first reported instance of a MagNav system operating alongside a visual navigation system on an attritable, one-way attack drone, according to SandboxAQ. Lumberjack, developed by Northrop Grumman in under 14 months from concept to first flight, is designed as a multi-use loitering munition.
