Northrop Grumman Unveils Next-Gen Hybrid Electric XRQ-73 X-Plane for DARPA

Northrop Grumman Corporation has taken a significant leap forward in aviation innovation with the announcement of the XRQ-73, an uncrewed aircraft developed under DARPA's Series Hybrid Electric Propulsion AiRcraft Demonstration (SHEPARD) program. This groundbreaking project, officially designated as an X-plane, represents a collaboration between Northrop Grumman and its subsidiary, Scaled Composites. The XRQ-73, equipped with hybrid electric propulsion, promises to revolutionize military aviation with enhanced capabilities and efficiency.

The SHEPARD program, an "X-prime" initiative, focuses on leveraging advanced technologies to mitigate system-level integration risks and rapidly mature a new, mission-focused aircraft design. Steve Komadina, the SHEPARD program manager, emphasizes the program's goal to develop a propulsion architecture and power class that could offer substantial benefits to the Department of Defense.

The development of the XRQ-73 builds upon component technologies from previous projects, such as the AFRL/IARPA Great Horned Owl (GHO) project. This innovative approach aims to produce a long-endurance, missionized aircraft that can be quickly deployed in various defense scenarios. The collaboration between DARPA, the Air Force Research Laboratory (AFRL), the Office of Naval Research (ONR), and other key stakeholders ensures that the XRQ-73 is designed to meet the rigorous demands of modern warfare.

The prime contractor for the SHEPARD program is Northrop Grumman's Aeronautics Systems sector based in Redondo Beach, California. The project also involves several major suppliers, including Scaled Composites, Cornerstone Research Group, Inc., Brayton Energy, LLC, PC Krause and Associates, and EaglePicher Technologies, LLC. Together, these organizations are working to bring the XRQ-73 to life.

Weighing approximately 1,250 pounds, the XRQ-73 is classified as a Group 3 Unmanned Aerial System (UAS). The aircraft's first flight is anticipated by the end of 2024, marking a significant milestone in the advancement of hybrid electric propulsion technology. This next-generation aircraft is expected to demonstrate superior endurance and efficiency, making it a valuable asset for the Department of Defense.

The SHEPARD program and the development of the XRQ-73 underscore Northrop Grumman's commitment to pushing the boundaries of aviation technology. By integrating hybrid electric propulsion systems, the XRQ-73 aims to provide the military with a versatile and efficient uncrewed aircraft that can adapt to various missions and operational environments.

As the XRQ-73 prepares for its maiden flight, the collaboration between Northrop Grumman, Scaled Composites, and other partners showcases the potential of hybrid electric propulsion in transforming the future of military aviation. This innovative aircraft represents a significant step forward in developing advanced uncrewed systems that can enhance the capabilities and effectiveness of the Department of Defense's operations.
