Carrying decades of experience, the fourth-generation DESEAVER MK-4 system exhibits remarkable flexibility, providing a 360° defense coverage, significantly enhancing the survival rate of surface vessels.

This system's proficiency lies in rapidly and accurately deploying decoys from multiple launchers to counter simultaneous threats, thus, demonstrating impressive operational versatility.

Upon continuously receiving threat data from various onboard sensors, the DESEAVER MK-4 system effectively evaluates, classifies each threat, and generates a unique defense plan tailored to the specific threat.

This approach is based on the customer's anti-missile doctrine, therefore providing a personalized defense solution. Using advanced deception and confusion tactics, the DESEAVER MK-4 activates an array of stabilized launchers, deploying a diverse set of decoys with precise positioning and timing.

The DESEAVER MK-4 is available with three types of launchers: Fixed Rocket Launcher Unit (FRLU), Rotating Rocket Launcher Unit (RRLU), and Stabilized Rocket Launcher Unit (SRLU), each designed to be adaptable to different types of rockets and decoys. This configurability is tailored according to the type of vessel and customer requirements, further exemplifying its adaptability.

This latest generation system is fully interoperable with other onboard combat systems, such as CMS, ESM, EW, Radar, and Navigation systems. All activities are recorded for later debriefs, and Course to Steer (CtS) recommendations are provided, making the DESEAVER MK-4 an advanced, highly effective defense solution.

Lightweight, modular, and with a small footprint, the DESEAVER system can be customized for a wide range of platforms, from patrol boats to frigates, establishing Elbit Systems' DESEAVER MK-4 as the new generation of Electronic Warfare Systems for the Israeli Navy and beyond.
