SLICK 32 is the naval operator term for the AN/SLQ-32 electronic warfare suite, the primary electronic warfare platform of the United States Navy. It was first implemented on US Navy ships in the 1970's, at first it was a simple threat warning system that could detect high-band radar signals like the kind used by the guidance system of an incoming missile or aircraft. Since then the system has gone through many changes and upgrades and is capable of much more than it originally was. Arleigh Burke-class destroyers carry the most upgraded version of the SLICK 32, it addition to being able to receive high-band signals from missile and aircraft it can also pick up the far less powerful signals of surveillance and targeting radars, providing a passive targeting system for their Harpoon anti-ship missiles. SLICK 32 systems can also jam the radar and sonar of enemy vessels and incoming missiles and interfaces with the ship's MK36 decoy countermeasure system and can automatically launch chaff and infrared decoys when it detects the radar signal of an incoming missile or launch sonar decoys when it detects the hydrophone guidance system of an incoming torpedo.
