Tycho.AI Halley VTOL Drone Intercepts Shahed Replica During U.S. Military T-REX 26-2 Trial
AI Analysis
Tycho.AI's Halley VTOL drone successfully intercepted a Shahed-136 replica and conducted a strike against a ground target during the U.S. military's T-REX 26-2 exercise. The demonstration showcased both autonomous and operator-controlled capabilities, achieving TRL-6. The system is designed as a low-cost counter-UAS solution, addressing the cost imbalance in defending against inexpensive loitering munitions.
Key Takeaways
- Tycho.AI's Halley Group 1 VTOL UAS intercepted a Shahed-136 replica in mid-air.
- The Halley system demonstrated both intercept and strike capabilities during T-REX 26-2.
- The drone achieved a maximum speed of 165 mph, altitude up to 10,000 ft, and range of 35km with a 1kg payload.
- Halley utilizes Tycho.AI’s Voyager autonomy stack for fully autonomous operation.
- The system is designed for rapid deployment (under 30 seconds) and reconfiguration with modular components.
Why It Matters
This demonstration highlights a potential shift towards lower-cost, drone-based counter-UAS systems. The Halley's success against a Shahed replica suggests a viable approach to mitigating the threat of inexpensive, yet effective, loitering munitions. Further development and potential procurement could significantly alter short-range air defense strategies.
Tycho.AI Halley VTOL Drone Intercepts Shahed Replica During U.S. Military T-REX 26-2 Trial
CAMBRIDGE, Mass. — May 26, 2026 : Cambridge-based AI startup Tycho.AI has successfully demonstrated its Halley Group 1 vertical take-off and landing (VTOL) uncrewed aerial system (UAS) during a recent U.S. military evaluation in Indiana, where the platform intercepted a replica of an Iranian-designed Shahed-type one-way attack drone in mid-air and completed a separate strike against a ground target.
The demonstration took place during the Technology Readiness Experimentation event, T-REX 26-2, held at Camp Atterbury from May 4 to 15, 2026. Organized by the Office of the Under Secretary of War for Research and Engineering, the exercise evaluates emerging military technologies in operationally representative conditions. The latest event focused on low-cost short-range air defense systems and interceptor capabilities designed to counter modern aerial threats.
During the evaluation, the Halley VTOL completed 39 assessed test flights in both operator-controlled first-person view and fully autonomous configurations. One of the most significant demonstrations involved the successful interception of a replica of the Iranian-designed Shahed-136, a long-range loitering munition that has been widely employed in conflicts against military and infrastructure targets over distances of hundreds of kilometers. In addition to the aerial intercept, the platform also conducted a one-way attack mission against a ground target during the same event, demonstrating its ability to perform multiple operational roles.
Tycho.AI stated that the Halley system is intended to provide a lower-cost approach to countering one-way attack drones, addressing the cost imbalance that often emerges when militaries rely on expensive air defense assets to intercept relatively inexpensive loitering munitions.
Flight Performance and Platform Design
Classified as a Group 1 UAS, Halley weighs approximately 5.2 pounds (2.3 kilograms) and is built around a lightweight modular tailsitter VTOL configuration with folding wings. The platform uses a zero-tool assembly design that allows deployment from storage to operational flight in less than 30 seconds. Its modular architecture also supports rapid mission reconfiguration, including extended-range winglets for missions exceeding 80 kilometers and a high-speed setup capable of dash speeds above 200 miles per hour.
During T-REX 26-2, the system achieved a maximum speed of 165 miles per hour, operated at altitudes ranging from 9 feet to 10,000 feet, and completed missions with a maximum flight distance of 35 kilometers. The aircraft carries a payload capacity of roughly one kilogram and can operate either through operator control or fully autonomous mission execution using Tycho.AI’s Voyager autonomy stack.
Following the exercise, Halley achieved Technology Readiness Level 6 (TRL-6), indicating the system had been demonstrated in a relevant operatio
