NAVSUP WSS anticipates a follow-on five-year requirements contract for repair coverage of the items listed in Attachment A/Exhibit A, including NSNs, part numbers, nomenclature, and estimated yearly quantities. The items are flight critical and/or lack adequate technical data for full and open competition, so Government source approval is required before award; the only qualified source identified is BAE Systems Information & Electronic Systems Integration Inc. (CAGE 19397). Non-approved sources must submit the source-approval information required by the NAVSUP WSS brochure with their offer, and offers missing required data will not be considered. If source approval cannot be completed in time to meet Government requirements, award may proceed based on Fleet support needs.
