A CV-22 Osprey, flown by the 8th Special Operations Squadron, hangs in the anechoic chamber at the Joint Preflight Integration of Munitions and Electronic Systems hangar March 6 at Eglin Air Force Base, Fla. The Osprey is currently in the chamber for approximately four weeks to test upgraded Electronic Warfare systems. The J-PRIMES anechoic chamber is a room designed to stop internal reflections of electromagnetic waves, as well as insulate from exterior sources of electromagnetic noise. J-PRIMES provides this environment to facilitate testing air-to-air and air-to-surface munitions and electronics systems on full-scale aircraft and land vehiclesprior to open air testing.
