Nomenclature: GSS-1497B
Part Number (Shielded): 206623
Part Number (Unshielded):


Gichner's lightweight model GSS-1497 electronic equipment shelter goes beyond the normal lightweight shelter construction technology. The GSS-1497 offers the lightest enclosure possible that is consistent with rugged mobility, RFI integrity, and performance under environmental extremes.

The GSS-1497 utilizes the same construction method applied in the combat-proven S-250 and S-280 shelters. Sandwich panel construction consists of a polyurethane foam core, aluminum skins, and a framework of high strength welded and riveted aluminum alloy extrusions. This traditional foam-and-beam panel construction allows for quick, easy installation of strong rivnut anchor points for mounting mission equipment. Foam-and-beam construction facilitates ease of modification, repair, and maintenance.

At 547 lbs., the GSS-1497's reduced weight increases the maximum payload and extends the range of the HMMWV during tactical operations. Your specific mission requirements can be met by tailoring the GSS-1497 without violating the payload requirements of the HMMWV. Since the shelter was designed for dedicated use with the HMMWV, bulky tie-down slings are not required. The GSS-1497 is easily bolted onto the vehicle with a bolt-on attachment kit. C-130 drive-on/back-off capability meets your transportation needs.
