Field Testing the WASP Air Defence System

ENS Dynamics participates in armasuisse trials in Graubünden

In December 2025, ENS Dynamics took part in a series of armasuisse‑led drone trials at the Hinterrhein firing range in the canton of Graubünden. The objective of the tests was assessing the current technological maturity of domestically developed drone and counter‑drone capabilities under realistic alpine conditions.

For ENS Dynamics, the trials also represented a high‑value testing opportunity: a chance to gather critical flight, tracking, and interception data in a controlled environment that is otherwise difficult to access within Switzerland’s regulatory framework.

A controlled test environment with real operational value

The Hinterrhein site, located at over 1,600 meters above sea level, offers narrow valleys, complex terrain, and challenging weather conditions. According to the organizers, this makes it an ideal environment to evaluate maneuverability, robustness, reaction times, and system effectiveness.

During the tests, ENS Dynamics demonstrated prototypes of its WASP Interceptor in interception scenarios observed by military representatives and journalists. Their purpose was to demonstrate the system’s TRL level, collect data, identify limitations, and accelerate learning.

From ENS Dynamics’ perspective, the outcome was very positive and the data gathered during the flights directly feeds into ongoing system improvements and future development cycles.

The role of the WASP Interceptor

The WASP Interceptor is a purely defensive surface‑to‑air system. Its sole purpose is to protect people, infrastructure, and military assets from hostile drones.

WASP is designed to intercept airborne threats, such as reconnaissance drones or loitering munitions, and neutralize them in flight. It does not attack ground targets and is not intended for offensive strike missions.

The system consists of multiple autonomous interceptor drones, a launcher, a ground‑based radar for detection and tracking, and a processing unit enabling autonomous interception once authorized by a human operator.

Cost‑effective defence in a rapidly changing threat landscape

The trials took place against the backdrop of a rapidly evolving security environment. Drones have become inexpensive, numerous, and expendable, fundamentally changing modern warfare. Defending against such threats using traditional air‑defense missiles is often economically unsustainable.

The WASP Interceptor is designed with this reality in mind. Its development prioritizes simplicity, affordability, and scalability - key attributes for countering saturation attacks and adapting to fast‑moving technological change.

At the same time, the trials highlighted that no system is yet perfect. Continuous iteration, testing, and improvement are essential. ENS Dynamics fully shares this assessment: modern drone defense is not about static solutions, but about rapid learning cycles and operational feedback.

Looking ahead

ENS Dynamics will continue to analyze the data collected in Hinterrhein and integrate the findings into the next development stages of the WASP Interceptor. The company welcomes rigorous testing, critical assessment, and transparent dialogue, because effective drone defense can only be built through realism, iteration, and collaboration.

The Graubünden trials were an important step on that path.
