The Department of Defense, specifically the Naval Air Systems Command, is seeking to develop the F-35 Common Configuration Aggregation and Reporting Tool (CART) through a sole source contract with Lockheed Martin Aeronautics Company in Fort Worth, Texas. The initiative aims to enhance development and testing efficiencies by creating a capability to generate developmental build configurations from a single mission system software build release repository. This procurement is critical for the F-35 "Lightning II" Joint Program Office, as it involves proprietary technical documentation and expertise unique to Lockheed Martin, which is the sole designer and integrator of the F-35 aircraft. Interested parties may submit capability statements to Olivia Russ at olivia.russ@jsf.mil, although this notice does not constitute a request for competitive proposals, and the government retains discretion over the procurement process.
