This opportunity is for the procurement of 5 units of a specific power supply (NSN 7H-6130-200014703). The government intends to solicit and negotiate with only one source, as it does not own the data or rights needed for competitive repair or purchase, and reverse engineering is uneconomical. Delivery locations are New Cumberland, PA, and Tracy, CA. All responsible sources may submit capability statements or proposals for consideration. Proposals will be considered if received within 45 days of the synopsis publication (or 30 days under an existing Basic Ordering Agreement).
