U.S. Army Redstone Test Center (RTC), a U.S. Army Test and Evaluation Command organization on Redstone Arsenal in Huntsville, Alabama, encompasses more than 14,000 acres and provides technical expertise, ranges, laboratories, and live, virtual and constructive capabilities for aviation, missile, sensor, subsystem and component testing. RTC also supports small-rocket, uncrewed-system and cyber-resiliency testing; current work includes missile-flight-test instrumentation and the 2026 construction of the Military Systems Electromagnetic Test Support (MSETS) facility. This is a controlled military test center, not a general walk-in visitor attraction; confirm authorization and installation access before travel.
