23--Trailer Mounted Support System - Medium Without Tent

Description Product Manager Force Sustainment Systems (PM FSS) has a requirement to field trailer mounted support systems in support of Standardized Integrated Command Post System (SICPS) Command and Control (C2) platforms. At this time, PM FSS is soliciting informati on from manufacturers of readily available off-the-shelf trailer mounted systems that consist of a trailer, an Environmental Control Unit (ECU) and a power generation system-all components must be capable of operating in the tactical environments defined b y this document and the trailer system must have sufficient storage capacity for a 400-500 square foot tent and all its ancillary components. The configuration described above shall, herein, be referred to as THE SYSTEM. The system to be identified shall be the solution for the Trailer Mounted Support System (TMSS) Medium. All information gathered will give the U.S. Army an opportunity to determine whether a Commercial Off The Shelf (COTS) trailer mounted ECUs/Power Units/Tent Systems can satisfy unique military tactical battlefield requirements. PM FSS intends to consider existing commercial items and modified commercial items that meet the minimum requirements listed in Section A, General System Description. Please provide written responses to this market survey within 25 calendar days from the posting date of this survey. Suppliers are requested to provide manufacturers’ product information sheets, photos, a strategy and a schedule to meet any requirements that the proposed product does not currently meet an estimated unit price for their proposed system, and answers to the questions in Section B of this Request for Information. PM FSS shall review all submittals and may invite vendors to Natick, MA to demonstrate their product or visit vendor’s facilities to witness a demonstration a t their location. Information on the High Mobility Multi-Purpose Wheeled Vehicle (HMMWV) and Modular Command Post System (MCPS) will be provided upon request. A.
