Hush House Renovations 2016
The South Carolina Air National Guard’s Enclosed Noise Suppression System Structure, or “hush house,” undergoes renovations 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.
