Hush House Renovations 2016
Civilian construction workers perform renovations on the South Carolina Air National Guard’s Enclosed Noise Suppression System Structure, or “hush house,” at McEntire Joint National Guard Base, S.C., March 10, 2016. The renovations occur approximately once every 10 years to keep the structure free of rust and other environmental elements that naturally occur over time.
