NAVAIR intends to issue a sole-source contract modification to Raytheon in Tucson, AZ, to procure critical supply chain management data deliverables for the Tomahawk weapon system. The justification is that Raytheon is the sole designer and manufacturer, possessing the unique technical knowledge and tooling required. The notice explicitly states it is not a request for competitive proposals. However, all responsible sources may submit a capability statement for agency consideration. Subcontracting opportunities should be sought directly from Raytheon at the provided Arizona address.
