The XRQ-73 was designed and built by Northrop Grumman to support the advancement of next-generation propulsion systems for lightweight autonomous aircraft. The programme focuses on hybrid-electric propulsion technologies intended to improve operational flexibility and aircraft efficiency.
According to the company, the XRQ-73 combines fuel efficiency with reduced emissions through its hybrid-electric propulsion system. Northrop Grumman said the technology could enable new mission possibilities and support the development of future aircraft designs.
The flight test campaign is intended to demonstrate advances in autonomous propulsion technologies for lightweight uncrewed aircraft. The company said the programme aligns with DARPA’s efforts to develop next-generation autonomous aviation capabilities.
Northrop Grumman stated that the demonstration supports the evolution of mixed-fuel lightweight aircraft systems. The company added that hybrid-electric propulsion could expand the operational possibilities of autonomous air platforms.
The XRQ-73 programme also builds on Northrop Grumman’s experience in autonomous flight systems. According to the company, it has accumulated more than 500,000 autonomous flight test hours over seven decades of work in autonomy technologies.
The company said the aircraft represents another step in advancing lightweight uncrewed aviation systems. Northrop Grumman added that the programme is intended to support future operational requirements for autonomous aircraft.
