• US Army-built drone motors power record 521-minute flight.
• New domestic production capability aims to reduce dependence on foreign-made components.
• Tobyhanna Army Depot facility produces motors and circuit cards.
• Army Materiel Command expands domestic production of small-drone components.

This achievement may signal the US Army's growing capability to secure domestic component supply chains for military drones, which could reduce dependence on foreign-made components and enhance national security. The development suggests a shift towards increased domestic production of critical drone components, which may have significant implications for the military's drone programs.
