A 413th Flight Test Squadron HH-60W hangs in the anechoic

A 413th Flight Test Squadron HH-60W hangs in the anechoic chamber at the Joint Preflight Integration of Munitions and Electronic Systems hangar Jan. 6 at Eglin Air Force Base, Fla. The Whiskey entered the chamber for approximately seven weeks of defensive systems testing. 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 vehicles prior to open air testing.
