A 40th Flight Test Squadron F-16 Fighting Falcon sits in the anechoic chamber after completion of the initial round of testing simulations on the new M-7 software upgrade on 30 October 2014 at Eglin AFB, Florida. The M-7 software provides multiple advanced capabilities to the aircraft. The anechoic chamber, located in the Joint Preflight Integration of Munitions and Electronic Systems building, is a room designed to stop reflections of either sound or electromagnetic waves. The room is insulated from exterior sources of noise. JPRIMES provides an environment to facilitate testing air-to-air and air-to-surface munitions and electronics systems on full-scale aircraft and land vehicles prior to open air testing.
