The Department of Defense, specifically the Department of the Navy, is seeking to procure 86 units of a power supply assembly under the presolicitation notice for NSN 7H-6130-015252167. The procurement is governed by the authority of FAR 6.302-1, indicating that the Government intends to negotiate with only one source due to the lack of available data or rights for alternative sourcing, making it uneconomical to reverse engineer the part. This power supply assembly is critical for military applications, and interested parties are encouraged to submit their capabilities and interest within 45 days of the notice, with all submissions directed to Alexander Stimeling at the provided contact details.
