Silencio

A C-12 Huron sits in the anechoic chamber at Eglin Air Force Base, Fla. The aircraft was part of a joint retrofitting test mission among the Army, Navy and Air Force to test their electronic warfare systems. The Army provided the aircraft that housed the Navy's electronic countermeasure systems, which was tested by the Air Force. An anechoic chamber is a room designed to stop reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. The The Joint Preflight Integration of Munitions and Electronic Systems, a subsidiary of the 46th Test Wing, has hosted similar joint test missions for more than five years in the chamber. 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.
