These items require Government source approval prior to award. Non-approved sources must submit the information detailed in the NAVSUP WSS Source Approval Brochure with their proposal, and offers missing required data will not be considered. If source approval cannot be processed in time to meet Government requirements, award may proceed based on Fleet needs. Firm-fixed-price pricing is sought; if it cannot be determined, the PCO should be informed. The warranty is 12 months with defects reported within 60 days of discovery, and early/incremental deliveries are accepted and preferred.
