Purchase Description_TESS Trailors.pdf

This Purchase Description defines the requirements for a Towable Expeditionary Shelter System – Small (TESS-S). The system shall be a self-contained, rapid-deployment, hard-sided mobile workstation designed for command and control (C2) and administrative operations in austere and expeditionary environments. The system is intended to provide a climate-controlled, insulated, and mobile workspace that can be quickly emplaced and displaced to support agile and distributed military operations.

1.0 Salient Characteristics

The TESS-S shall meet the following minimum essential requirements. The contractor may offer a system with characteristics that meet or exceed these specifications.

1.1 System Configuration and Mobility:

• The system shall be fully integrated onto a standard military High Mobility Multipurpose Wheeled Vehicle (HMMWV) towable trailer chassis.

• The design shall be containerized to protect internal components during transport.

• The system must be transportable via road, rail, sea, and air, to include compatibility with a 463L pallet and helicopter sling-load operations.

• The entire system must be engineered for high mobility and capable of traversing challenging, off-road terrain.

1.2 Deployment and Workspace:

• The system shall be deployable and mission-ready in under six (6) minutes by a maximum of two (2) trained personnel without the need for special tools or material handling equipment.

• When deployed, the expandable shelter shall provide a minimum of 86 square feet of usable, climate-controlled, and insulated interior workspace.

• The shelter shall feature a hard-sided, expandable container design. The deployed structure may utilize a hybrid of hard-sided and soft-sided (textile) materials.

• The shelter must be equipped with integrated, multi-layer fabric covers that are fully insulated and provide a complete blackout capability for light discipline.

1.3 Integrated Support Systems:

• Power: The system shall include an integrated power generation system (e.g., multi-fuel generator) and power distribution network to support all onboard equipment and user-provided devices. It must provide both AC and 24VDC power options.

• Environmental Control Unit (ECU): The system must include an integrated HVAC (heating, ventilation, and air conditioning) system capable of maintaining a climate-controlled environment suitable for personnel and electronic equipment in a wide range of global climates.

• Lighting: The shelter shall be equipped with integrated internal LED lighting, featuring both standard white light and tactical green light modes.

1.4 Construction and Durability:

• The system must be constructed of durable, lightweight materials, such as aluminum and composites, suitable for sustained operations in austere environments.

• The system must be designed and tested to meet or exceed the environmental and mechanical specifications of MIL-STD-810G/H.

• All exterior waterproof fabric components must be Berry Compliant and meet the performance specifications of MIL-PRF-44103D.

2.0 Quantity

• Five (5) complete TESS-S units.

3.0 Delivery

• Delivery Date: All units must be delivered no later than 31 July 2026.
