The whole defense community recognizes the threat posed by UAV on the battlefield and the current lack of economically sustainable counter systems. MBDA’s answer is Sky Warden, a modular, scalable and evolvable system designed to integrate and control a large panel of sensors and effectors, in particular High-Energy Lasers (HEL), in order to neutralize class one and two UAVs. The lack of knowledge of HEL performance against UAV threats leads MBDA to explore experimentally HEL-UAV engagement scenarios. With tests performed at laboratory scale, we examine the level of vulnerability (Kill Probability) of UAVs in known conditions. The representativeness of dynamic laser-target interaction emulating atmospheric perturbations (absorption, diffraction, turbulence…) and target attitude evolution (incidence, speed…) is essential for the progressive development of meaningful vulnerability models. MBDA and ALPhANOV operate a versatile and common test facility, the Vulnerability Test Facility (VTF), enabling the reproduction of realistic engagement conditions. The improvement and implementation of its experimental capabilities for target vulnerability assessment lead to the continuous enrichment of an experimental database. Based on this data and a generic vulnerability approach, MBDA extends its field of knowledge in order to improve the effectiveness of destruction of UAVs by HEL.
