U.S. startup shoots down Shahed replica with tiny drone
AI Analysis
Tycho.AI's Halley Group 1 VTOL UAS successfully intercepted a Shahed replica drone during the T-REX 26-2 exercise, demonstrating both counter-drone and attack capabilities. The system utilizes onboard AI for autonomous operation in GPS/communication-denied environments and features secure video transmission. Halley achieved Technology Readiness Level 6, indicating field-validated capability.
Key Takeaways
- Halley intercepted a Shahed replica, demonstrating a cost-effective counter-UAS solution against a significant threat.
- The system operates autonomously, maintaining functionality even under electronic warfare conditions (jamming/spoofing).
- Halley achieved a speed of 165 mph and range of 35km, exceeding typical Group 1 UAS performance.
- Automatic Target Recognition (ATR) reduces operator workload and enables faster engagement.
- The T-REX program provides a structured path for emerging technologies to be evaluated by the military without full acquisition processes.
Why It Matters
This technology offers a potential solution to the growing threat of low-cost drones like the Shahed-136, which have proven effective in recent conflicts. Halley's autonomous capabilities and resilience to electronic warfare are crucial for maintaining operational effectiveness in contested environments. Successful T-REX validation positions Tycho.AI for potential future contracts and wider adoption within the US military.

A Cambridge-based AI startup successfully intercepted a replica of the Iranian-designed Shahed-type long-range one-way attack drone in mid-air during a U.S. military test event in Indiana earlier this month, using a small, high-speed vertical take-off and landing aircraft that can be built at low cost and operated without a persistent communications link.
Tycho.AI’s Halley Group 1 VTOL uncrewed aerial system completed 39 evaluated test flights at the Technology Readiness Experimentation event known as T-REX 26-2, held at Camp Atterbury, Indiana from May 4 to 15, demonstrating both counter-drone interception and one-way attack capability against a ground target in the same exercise.
The Shahed replica interception is the detail that anchors the entire demonstration in operational reality. The Shahed-136, the loitering munition that Iran supplied to Russia in large quantities for use against Ukrainian infrastructure and military targets, has become one of the most strategically significant cheap weapons of the current era, capable of striking targets hundreds of kilometers from launch with enough accuracy to destroy power substations, fuel depots, and command facilities. Ukraine and its partners have spent enormous effort developing ways to shoot it down, with everything from fighter jets to modified anti-aircraft guns pressed into service as interceptors. A small, fast, low-cost VTOL that can autonomously intercept a Shahed replica represents a qualitatively different answer to that problem, one that matches the cost structure of the threat rather than countering a cheap weapon with an expensive one.

Halley reached a maximum speed of 165 miles per hour during the T-REX exercise, operated at altitudes ranging from 9 to 10,000 feet, and completed a maximum flight distance of 35 kilometers. Those numbers define the operational envelope of a Group 1 UAS, the classification covering unmanned aircraft weighing under 20 pounds, flying below 1,200 feet in standard operation at speeds under 100 knots. Halley’s 165 mph top speed pushes well above the typical Group 1 performance ceiling, which is precisely what makes aerial interception of fast-moving threats plausible for a platform in this size and cost class.

Sertac Karaman, Tycho.AI’s founder, described what the T-REX results confirmed: “Halley’s performance validates that our vision for a small, fast, agile tactical UAS is not just theoretical; it is ready for the battlefield. T-REX provided the perfect venue to demonstrate Halley’s versatility across multiple mission sets and its direct effectiveness against moder
