The AN/SLQ-32 is a shipboard electronic warfare suite built by the Raytheon Company of Goleta, California and The Hughes Aircraft Company. It is currently the primary electronic warfare system in use by U.S. Navy ships. Its operators commonly refer to it as the "Slick-32". Variants The SLQ-32 was originally conceived in the 1970s to augment the AN/WLR-1, which had been in service since the early 1960s. It was later determined to save costs to replace the various WLR-1 series suites with the SLQ-32 as a stand-alone system. As originally designed, the SLQ-32 was produced in three variants, the (V)1, (V)2 and (V)3. Later in its service life, additional versions were built, the (V)4 and (V)5. Today, (V)6 and (V)7 versions are in production. The Air Transport Rack sized processors were supplied by ROLM Mil-Spec Computers in San Jose, California. AN/SLQ-32(V)1 – A simple threat warning receiver. It was capable of receiving low frequency, high-band radar signals of the type commonly emitted by anti-ship missile terminal guidance radars and long-range surveillance radars. The (V)1 was installed on auxiliary ships and small combatants like frigates. This variant of the system was phased out as equipped ships became decommissioned. AN/SLQ-32(V)2 – Initially the most common variant, the (V)2 expanded on the (V)1's capabilities with new receiving antennas for increased radio frequency coverage. It added the ability to detect high frequency targeting and fire-control radars, providing early warning against an imminent anti-ship missile attack. The (V)2 was installed on frigates, destroyers, and Coast Guard cutters. Many (V)2 suites have been upgraded to (V)3. AN/SLQ-32(V)3 – The (V)3 added antennas with electronic attack capability, able to actively jam targeting radars and anti-ship missile terminal guidance radars. The (V)3 was installed on various combatants such as destroyers, cruisers, battleships, large amphibious ships, and high-value replenishment vessels. (V)3 systems are currently being replaced with (V)6. AN/SLQ-32(V)4 – Designed for installation on aircraft carriers, the (V)4 consisted of two (V)3 systems, one for each side of the ship, tied to a common computer and display console. Additional line replaceable units and software were added to support the wide separation of the two antenna/electronics enclosures. (V)4 systems will be replaced with (V)6. AN/SLQ-32(V)5 – The (V)5 was built as a response to the Stark incident in 1987. The (V)5 system incorporates a compact version of the (V)2 system along with an active jamming module—referred to as "Sidekick"—to thes, which
