The Naval Air Systems Command is seeking sources capable of providing supplies and services for Digital Interrogator AN/UPX-45 and AN/UPX-50 RP2 Trouble Report software corrections, focusing on MODE 5 reliability and aircraft safety. The anticipated period of performance is 18 months, with an estimated value of $4M, and work is expected to be performed at the contractor’s facilities within the United States. The government intends a sole-source award to BAE Systems due to a lack of technical data and data rights, but all responsible sources are encouraged to submit capability statements. Deliveries of updated units with software corrections are needed no later than FY28, with contract award projected for November 2026. Interested firms must demonstrate access to necessary technical data or an alternative approach, and submit a capabilities statement by the response date.
