S-250 (PTT) COMMUNICATION CELL transports and operates base communication equipment with 1 1/4-ton military trucks (M705, M715, and XM561), 1 1/4-ton Type E commercial utility cargo vehicle (CUCV), 1 1/4-ton High Mobility Multipurpose Wheeled Vehicle (HMMWV), military cargo aircraft such as the C-130, helicopter, and by sea or rail unit. This high strength, insulated, all-weather, general purpose unit is designed to meet the user's specifications for complete systems integration.
The S-250 shelter is a foam and beam bonded sandwich construction consisting of a polyurethane foam core, aluminum skins and a framework of high strength aluminum alloy extrusions. Foam and beam panel construction provides high strength to weight ratios and facilitates ease of modification, repair, and maintenance.
