This procurement is critical as the item is flight critical, requiring government source approval prior to contract award, and the technical data necessary for competitive sourcing is not available. Interested suppliers must be previously approved sources or submit the required documentation for source approval, as outlined in the NAVSUP WSS Source Approval Information Brochures, to be considered for this contract. Proposals must be submitted within 45 days of this presolicitation notice, and interested parties can contact Katlyn M.
