NAVAIR at Patuxent River, MD intends to award a follow-on order under a Basic Ordering Agreement with General Atomics Aeronautical Systems, Inc. for comprehensive Engineering Logistics Support for the Marine Air-Ground Task Force Unmanned Aircraft System Expeditionary/Medium Altitude/Long Endurance (MUX/MALE) program. The work is intended to ensure operational readiness, sustainment, and continuous improvement of USMC-unique payloads and systems and includes program management, logistics, spares analysis, engineering services, lead systems integration, field maintenance, training, DMSMS mitigation, airworthiness, cybersecurity, software sustainment, and technical data management. The action will be sole-sourced to GA-ASI because it is the sole designer, developer, manufacturer, and integrator of the MQ-9 and the only contractor with the requisite knowledge, experience, and technical data. This notice is not a request for competitive proposals, but interested parties may identify their interest and capability, and companies interested in subcontracting should contact GA-ASI directly.
