Project set to bring greater clarity to familiar voice at Arnold AFB

Russell Cain, left, and Tre Powell with Mobile Communications America install an indoor siren system in the von Kármán Gas Dynamics Facility at Arnold Air Force Base, Tenn., July 11, 2024. This work is part of an ongoing siren system upgrade project occurring at Arnold. When completed, 13 outdoor siren systems and 11 indoor siren systems located across the installation will be upgraded to improve the clarity of messages broadcast through the systems. These systems, collectively referred to as the Giant Voice System, transmit audible spoken messages, accompanied by sirens depending on the situation, whenever a situation that those across Arnold should be made aware of arises. These broadcasts can include alerts related to the weather, testing and emergency situations occurring on the installation. (U.S. Air Force photo by Bradley Hicks)
