Aurora Flight Sciences has taken a major step forward in its experimental aircraft program, announcing that the fuselage of its X-65 demonstrator has arrived in Virginia for final systems integration.
The update, shared on April 2, signals that the project is moving from structural assembly into the critical phase before flight testing, with a first flight planned for 2027.
The Boeing subsidiary confirmed that teams are now installing core systems while other components continue production in West Virginia. The milestone reflects steady progress on a program that aims to rethink how aircraft are controlled in the air.
Transition to final integration phase
With the fuselage now in Virginia, engineers have begun installing electrical systems, propulsion components, and the aircraft’s advanced active flow control technology. At the same time, wing and tail structures are still being built at Aurora’s facility in Bridgeport, West Virginia.
“The X-65 fuselage has arrived! Our teams are now integrating electrical, propulsion, and AFC systems into the aircraft fuselage in Virginia, while wing and tail manufacturing is advancing at our facility in West Virginia,” the company said.
The shift to integration marks one of the most complex stages of aircraft development. It brings together separate systems into a single working platform that must perform reliably during future flight tests.
Aurora and the Defense Advanced Research Projects Agency reached a co-investment agreement in August 2025 to complete the aircraft and move toward flight. Since then, the effort has advanced through design reviews and into full-scale manufacturing.
A new way to control aircraft
The X-65, with a top speed of 537 mph, is being developed under DARPA’s CRANE program, which focuses on Control of Revolutionary Aircraft with Novel Effectors. The goal is to prove that aircraft can be controlled without traditional moving surfaces.
Instead of relying on flaps, rudders, or elevators, the X-65 uses jets of air to change how airflow moves across its wings. By directing these air streams precisely, the aircraft can adjust pitch, roll, and yaw.
In simple terms, the system allows the aircraft to maneuver using airflow rather than mechanical parts.
“The X-65 is part of the Defense Advanced Research Projects Agency – DARPA CRANE program to demonstrate active flow control (AFC) — technology that replaces traditional aircraft control surfaces with jets of air,” the company added.
This approach could reduce the number of moving parts on an aircraft, which may lower weight and simplify maintenance while improving aerodynamic efficiency.
Built as a dedicated test platform
The X-65 is not designed for operational use. It is a purpose-built demonstrator created to test new aerodynamic concepts under real flight conditions.
The aircraft features a wingspan of about 30 feet and a gross weight of roughly 7,000 pounds. These specifications provide a stable platform for repeated testing and data collection.
Its active flow control system uses pressurized air distributed through fourteen embedded effectors placed across the aircraft’s surfaces. These effectors are responsible for managing flight behavior without conventional control surfaces.
The aircraft also includes a triangular wing design and a modular structure. Engineers can adjust wing sweep angles and swap out components to test different configurations over time.
Path toward 2027 first flight
With integration now underway, the X-65 program is entering a decisive phase. The fuselage, wings, and engine diffuser were all produced in West Virginia before the fuselage was transported for final assembly.
Aurora believes the aircraft could play a long-term role in research even after its initial demonstration phase.
“We’re excited to continue our longstanding partnership with DARPA to complete the build of the X-65 aircraft and demonstrate the capabilities of active flow control in flight,” said Larry Wirsing, vice president of aircraft development at Aurora Flight Sciences.
“The X-65 platform will be an enduring flight test asset, and we’re confident that future aircraft designs and research missions will be able to leverage the underlying technologies and flight test data.”
As work continues across multiple facilities, the program is steadily moving toward its 2027 flight target.
