ERDC engineer improves Department of State protective shelter patent
The Hardened Alternative Trailer System (HATS) two-story protective structure used by Department of State, with additions of the recently patented weather-resistance and connective flashing components. The U.S. Army Engineer Research and Development Center’s Geotechnical and Structures Laboratory Research Civil Engineer Justin Roberts of Vicksburg, Mississippi, improved his previously patented Modular Anti-Ballistic, Blast and Forced Entry Resistant Shelter invention, part of HATS, with these capabilities.
