This is an unrestricted, firm-fixed-price RFP for 68 Ethernet transceivers, with no price breaks, under other than full and open competition due to the government's lack of complete technical data. Only approved sources (Mercury Systems and Lockheed Martin) may be solicited, and alternate offerors must submit a complete data package for evaluation. The solicitation is expected to issue in August 2026, with delivery required 274 days after order and items shipped to New Cumberland, PA under FOB Origin terms. Evaluation will be based on a best-value combination of price, delivery, past performance, technical acceptability, and socioeconomic factors. Reverse auctioning will not be used, and the acquisition is not being handled as a commercial item purchase.
