The SHEPARD vehicle, recently designated the XRQ-73, represents a significant step forward in the evolution of unmanned aerial systems (UAS), leveraging hybrid electric propulsion technologies to enhance performance and operational capabilities.
On Jul. 10, 2024, Northrop Grumman unveiled the design and construction of the Series Hybrid Electric Propulsion Aircraft Demonstration (SHEPARD) vehicle. This uncrewed air system, developed for DARPA, has been officially designated as the XRQ-73 X-plane.
The aircraft in the image released by Northrop Grumman features a sleek, stealthy flying wing design. It has a low-profile fuselage with sharp, angular edges to enhance aerodynamic efficiency and stealth capabilities. The wings are broad and tapered with clipped wingtips, and there are two prominent air inlets located on the upper surface of the fuselage. Between these inlets is a fairing, likely housing critical systems or payloads.
The overall design suggests a focus on minimizing radar and visual signatures, emphasizing its role as an advanced, unmanned aircraft for surveillance and reconnaissance missions.
In fact, the XRQ-73 SHEPARD, built in collaboration with Scaled Composites (a subsidiary of Northrop Grumman), is part of DARPA’s “X-prime” program. It utilizes hybrid electric architecture and advanced component technologies to rapidly develop a new mission-specific aircraft design with unique propulsion architecture and power capabilities for the Department of Defense.
