Lockheed Martin to provide design engineering services for AN/SLQ-32(V)6 of US Navy


According to a contract released on November 27, 2020, by the U.S. Department of Defense (DoD), Lockheed Martin Corp., Rotary and Mission Systems, Syracuse, New York, was awarded a $14,108,019 cost-plus-fixed-fee and cost-only modification to previously awarded contract N00024-18-C-5300 to exercise options for AN/SLQ-32(V)6 design agent engineering services.

AN/SLQ-32(V)6 or “SEWIP Lite”, the latest fielded variant of the AN/SLQ-32, incorporates receiver, antenna and combat system interface upgrades developed under the SEWIP Block 2 ACAT II program and adds the High Gain High Sensitivity adjunct sensor developed under the SEWIP Block 1B3 ACAT II program. SEWIP Lite is capable of both littoral and open ocean electronic surveillance. This system will be installed on fast U.S. Navy frigate class and U.S. Coast Guard Offshore Patrol Cutters.

The SLQ-32(V) is the principal EW (Electronic Warfare) system carried by major US Navy surface ships, with more than 450 systems produced to date. The (V)1 and (V)2 suites are passive, providing early warning, identification, and direction finding capability for simultaneous multiple threats. The (V)3 suite provides an additional active response for simultaneous jamming of multiple threats. The (V)4, an expanded version of the (V)3, is used on aircraft carriers. The (V)5, used on destroyers and frigates, integrates a passive (V)2 with an active jammer called "Sidekick." The SLQ-32(V) system has been in operation around the globe since the 1980s, and ongoing efforts to restore and upgrade older systems will extend the life of the SLQ-32(V) well into the 21st century.

The system achieves EW objectives by providing full threat band frequency coverage, instantaneous azimuth coverage, 100 percent probability of intercept and simultaneous response to multiple threats. It can detect aircraft search and target radars well before they detect the ship. The system's rapid response time ensures that jamming protection is enabled to prevent long-range targeting of the ship and to deceive missiles launched against the ship. The system has an on-line library of emitter types for rapid identification.
