Israel’s Elbit Systems has advanced naval survivability with the DESEAVER MK-4, a fourth-generation AI-powered decoy launching system that autonomously detects, assesses, and neutralizes complex, multi-directional missile threats in real time.
The system operates within Elbit’s Integrated Electronic Warfare Suite (IEWS), conducting automated threat prioritization and deploying both passive and active decoys from multiple trainable, stabilized launchers simultaneously to provide full 360-degree perimeter protection. Its anti-missile algorithms select the optimal decoy type and launch parameters for each threat, enabling rapid and precise soft-kill responses without human intervention.
Elbit has developed three launcher configurations for the DESEAVER MK-4: a Fixed Rocket Launcher Unit (FRLU), a Rotating Rocket Launcher Unit (RRLU), and a Stabilized Rocket Launcher Unit (SRLU). The RRLU and SRLU variants each hold 24 rockets and achieve full 360-degree coverage through rapid rotation. The system integrates directly with ship combat management systems and has completed successful sea trials aboard Israeli Navy vessels.
In March 2025, Elbit partnered with Rafael to supply DESEAVER MK-4, paired with Rafael’s decoys, to NATO European frigates, signaling strong international demand for the platform. Elbit positions the system as a critical upgrade path away from legacy fixed launchers, enhancing fleet survivability in modern contested naval environments.
