The Department of the Air Force is seeking sources for an operationally qualified missile warning system (MWS) for rapid integration into the USAF F-15EX Eagle II fighter aircraft. The MWS must alert aircrew to missile threats with minimal false alarms, use six pre-existing sensor locations, data/power cables, and cooling, and be easily, safely, rapidly, and organically installable/removable in the field by USAF maintenance personnel without aircraft configuration changes beyond LRU installation. This is a sources sought announcement only, not an RFP/RFQ/IFB, and no funds are available to pay for response preparation. Interested firms should submit an unclassified technical capabilities statement via DoD SAFE, limited to six pages, identifying a single MWS and describing operational approvals, production status, delivery timeline, LRU details, interfaces, safety, and environmental limitations. The anticipated NAICS code is 334511 with a small business size standard of 1,350 employees.
