WASHINGTON – U.S. Navy surface warfare experts are ordering additional advanced shipboard electronic warfare (EW) systems for surface warships like aircraft carriers, amphibious assault ships, cruisers, and destroyers under terms of a $63.3 million order announced Friday.

Officials of the Naval Sea Systems Command in Washington are asking the Lockheed Martin Corp. Rotary and Mission Systems segment in Liverpool, N.Y., for full-rate production of AN/SLQ-32(V)6 and AN/SLQ-32C(V)6 Surface Electronic Warfare Improvement Program (SEWIP) Block 2 systems.

SEWIP Block 2 is an evolutionary acquisition and incremental development program to upgrade the existing AN/SLQ-32(V) electronic warfare system aboard surface warships.

SEWIP provides enhanced shipboard EW for early detection, analysis, threat warning, and protection from anti-ship missiles. SEWIP Block 2 will enhance the shipboard EW systems's receiver and antenna group to meet the latest threats.

SEWIP Block 2 expands on the receiver and antenna group necessary to keep capabilities current with the pace of the threat and to yield improved system integration, Navy officials say.

The Lockheed Martin Block 2 SEWIP design is based on its integrated common electronics warfare system (ICEWS), which enables rapid reconfiguring of the system with commercial technology.

Mercury Systems in Andover, Mass., is providing advanced radio frequency (RF) microwave tuners and intermediate frequency (IF) products for SEWIP Block 2. Lockheed Martin chose the Mercury Echotek series microwave tuner and digital receiver, which are optimized for fast tuning and high performance.

Developed by Raytheon in the 1970s, the original AN/SLQ-32 systems employed passive radar technology for early warning, identification and tracking of enemy threats. Subsequent upgrades provided an additional active capability for simultaneous jamming of several different threats.

On this order Lockheed Martin will do the work in Liverpool, N.Y.; and Lansdale, Pa., and will be finished by February 2025. For more information contact Lockheed Martin Rotary and Mission Systems online at www.lockheedmartin.com/us/rms, or Naval Sea Systems Command at www.navsea.navy.mil.
