JA_SS DADC Redacted.pdf

This document is a Justification for Sole Source Acquisition for the Naval Air Systems Command (NAVAIR), focusing on updating software for the Digital Air Data Computer (DADC) used on F-5N/F aircraft operated by the United States Navy and Marine Corps. The specific requirement is to revise the current DADC software configuration to export fault codes and eliminate nuisance cautions displayed to aircrew, with a required delivery date of 03/06/2026.

The sole source provider is Innovative Solutions & Support (IS&S), who developed the original DADC as an avionics upgrade for F-5N/F aircraft. The proprietary nature of the DADC design and limited data rights mean only IS&S can provide this software update. The upgrade will process static and pilot pressures, total temperature, and local angle of attack input data, and will be transparent to the pilot. The document notes that the data rights for this procurement would cost approximately five times the upgrade's value, and the government does not currently wish to purchase additional data rights for this low-dollar procurement.
