SURFACE-TO-SURFACE MISSLE MODULE HVAC REPLACEMENT
STATEMENT OF WORK (SOW)
1.0 BACKGROUND
The current Commercial of the Shelf (COTS) Heating, Ventilation, and Cooling system used in the Littoral Combat Ship (LCS) Surface to Surface Missile Module (SSMM) as reliability problems. The design and development of a water-cooled HVAC system for SSMM that meets the system requirements is needed. Market research yielded no Commercial Off-The-Shelf (COTS) options available that meet these requirements. The production of two functional prototype units is required. Objective Quality Evidence (OQE) in the form of analysis is required as proof that the units meet the requirements. The government will conduct the environmental tests after the units are received. Environmental benchmark testing of the SSMM systems current HVAC units is included in the scope of this tasking.
