The Defense Advanced Research Projects Agency (DARPA) and General Atomics Aeronautical Systems have achieved key technical milestones on the LongShot program, bringing its air-launched unmanned vehicle, designated the X-68A, closer to flight testing planned as early as late 2026.

Recent successes include full-scale wind tunnel tests and demonstrations of the vehicle’s parachute recovery and weapons-release systems. The LongShot concept envisions an uninhabited aircraft launched from larger crewed platforms that can fly ahead of follow-on forces and engage hostile targets with its own air-to-air missiles, extending combat reach and enhancing pilot safety.

The system is intended to be adaptable across fighters, bombers, or deployment from mobility aircraft, with upcoming integrated flight tests slated to validate vehicle performance and safe employment methods. DARPA writes:

What was once only conceptual is now making steady progress toward reality.

DARPA’s LongShot with General Atomics Aeronautical Systems has successfully completed a series of technical milestones, moving its air-launched uninhabited vehicle – recently designated the X-68A – closer to flight testing.

Recent achievements, including full-scale wind tunnel tests and successful trials of the vehicle’s parachute recovery and weapons-release systems, demonstrate significant progress in developing this next-generation capability.

The LongShot program is designed to fundamentally change air combat operations. The program’s premise is an uninhabited aircraft that can be launched from a larger aircraft, fly ahead of follow-on forces, and engage enemy targets with its own air-to-air missiles. This approach augments traditional fighter aircraft, enabling them to remain farther from the front lines, drastically increasing pilot safety while extending the overall force package reach and mission effectiveness.

The LongShot concept is intended to be host-platform agnostic, providing opportunities to integrate an operational variant onto fighters, bombers, or employed as a palletized munition from mobility aircraft.

“LongShot burns down significant technical risk and presents a viable path for the military services to increase air combat reach and effectiveness from uninhabited, air-launched platforms,” said Col. John Casey, DARPA LongShot program manager. “With the help of our partners, we’ve completed critical milestones necessary for the integrated flight test campaign, which will validate vehicle performance and lay the foundation for efficient follow-on development.”

The program leverages expertise from a multitude of U.S. government stakeholders, including:

• The United States Air Force’s (USAF’s) Arnold Engineering Development Complex
• USAF’s Life Cycle Management Center
• USAF’s F-15 Program Office
• USAF’s 96th Test Wing
• Air Force Research Laboratory
• Naval Air Warfare Center Aircraft Division
• National Aeronautics and Space Administration
• U.S. Army Engineer Research and Development Center
• Aviation & Missile Center within the U.S. Army Combat Capabilities Development Command
• U.S. Army’s Redstone Test Center within the U.S Army Test and Evaluation Command
• U.S. Army’s Yuma Proving Grounds

General Atomics Aeronautical Systems, Inc. (GA-ASI) is the industry lead responsible for designing, building and demonstrating the LongShot concept.

With ground and integration testing currently underway, the program is building toward a flight test campaign as early as the end of 2026. These tests will prove the safe and effective employment of the X-68A from an F-15, confirm the flight worthiness of the LongShot vehicle, and demonstrate its ability to safely eject a captive sub-munition.
