Doppler Navigation Set (DNS) Parts and Repair

Close: Jan 30, 2026

The Army Contracting Command - Aberdeen (on behalf of the Army ILSC SCMD SSD) issued a sources-sought/RFI to conduct market research for parts and spares to support the ASN-128 Doppler Navigation System; the Government does not possess technical data packages and intends to collect capability/capacity information from sources that can manufacture the listed parts. The notice lists multiple specific NSNs and part numbers for circuit card assemblies, signal converters, and other electronic components and requests company information, CAGE, questionnaire responses, drawings, test results, and evidence of past performance. This is explicitly a sources-sought/RFI for planning purposes only (not an RFP/solicitation to award a contract), and the Government will not reimburse response costs.
