"One Defense's Sentinel network gave our range crews a single, auditable picture during joint interceptor trials — every detection and decision logged automatically."
"ONE-Vanguard's flight consistency across a dozen consecutive tests is what let us move the program into extended evaluation ahead of schedule."
"The Sentinel C2 audit trail made our after-action review straightforward — every operator action was timestamped and reviewable."
