DRASH (Deployable Rapid Assembly Shelter) is a portable, geodesic shelter that can be set up within minutes of arriving on site with no special tools. The structure is supported by composite struts. DHS Systems LLC handles all the manufacturing, maintenance, training and sales for these shelters.
DRASH shelters have footprints from 109 sq ft (10.1 m2) up to 1,250 sq ft (116 m2). Each DRASH shelter comes with flooring and ground covers manufactured from polyester and nylon to US military standards. DRASH also provides generators and trailers plus various accessories for the shelters themselves. Several of these accessories can be used to link shelters together. For transport or storage, the shelters pack down to less than 2% of its deployed size into a transport bag that can be stowed on a trailer or HMMWV. Teams of four to six can easily erect a shelter simply by pulling on the sides of the shelter and raising the shelter in designated "push points" on the shelter.
DHS Systems founder and CEO A. Jon Prusmack began building DRASH shelters more than 20 years ago after being inspired by pop-up geodesic domes he came across at trade shows. He founded the company in 1984 and DRASH shelters quickly started to be purchased by military units for use as command posts, tactical operations centers, communications centers, battalion aid stations, and forward surgical support stations.
In 2004, the Carlyle Group invested in DHS Systems and formed its new parent company DHS Technologies. In 2009, it was reported that the company was working on a line of shelters that better matched power supply to demand.
The company also plans to begin incorporating a new energy efficient insulation barrier, insect repellents and a shelter that can protect sensitive equipment from electro-magnetic pulses and radio frequency interference.
The United States Military and NATO are using DRASH shelters in place of the various tents and shelters used in the past. The Department of Defense has awarded DRASH several contracts.
