About this opportunity
The Department of the Navy Naval Air Systems Command Naval Air Warfare Center issued a Limited/Sole Source Justification Notice for software updates to the Digital Air Data Computer (DADC) used on F-5N/F aircraft operated by the United States Navy and Marine Corps. The contract, awarded on August 27, 2025, was granted to Innovative Solutions & Support (IS&S) as the sole source provider due to their proprietary ownership of the original DADC design and limited data rights availability. The specific requirement involves revising the current DADC software configuration to export fault codes and eliminate nuisance cautions displayed to aircrew, with the upgraded software processing static and pilot pressures, total temperature, and local angle of attack input data while remaining transparent to pilots. The justification notes that acquiring data rights for this procurement would cost approximately five times the upgrade's value, making sole source procurement more cost-effective than competitive bidding. The required delivery date for this software update is March 6, 2026, though the specific contract value remains redacted in the documentation.
