The Department of Defense, through the Naval Air Warfare Center Aircraft Division (NAWCAD), intends to award a contract for the procurement of MQ-4C Avionics Accessory Sets, specifically designed for the United States Navy and Royal Australian Air Force MQ-4C Triton Unmanned Air Systems (UAS). The contract will be awarded on a limited competition basis to the Original Equipment Manufacturer (OEM), Integrated Consultants Inc., and its authorized distributor, Northrop Grumman Corporation, for specific accessory sets that are critical for troubleshooting 1553 Data Bus and Ethernet systems on the MQ-4C UAS. These accessory sets are uniquely developed for the MQ-4C Triton UAS, and no alternative sources can fulfill the requirement due to the proprietary nature of the technical data. Interested parties may contact Mark Schnittman at mark.a.schnittman.civ@us.navy.mil for further information, with responses to this presolicitation notice due within 15 calendar days of publication.
