electronic warfare in the U.S. Navy and U.S. Coast Guard's WMEC -class ships. Future In 1996, a program called the Advanced Integrated Electronic Warfare System (AIEWS) was begun to develop a replacement for the SLQ-32. Designated the AN/SLY-2, AIEWS reached the prototype stage by 1999, but funding was withdrawn in April 2002 due to ballooning costs and constant delays in the projects development. It has since been replaced with Surface Electronic Warfare Improvement Program (SEWIP), which will replace the existing SLQ-32 hardware and technology in an evolutionary fashion. , SEWIP Block 2 upgrades were first installed on s in 2014, with full-rate production scheduled for mid-2015. Block 2 improved detection capabilities; better jamming is planned from 2017, but the 2013 sequestration cuts may push this date back a year. As of 2022, SLQ-32(V)7 (SEWIP Block 3) is undergoing low-rate initial production and is planned to be retrofit on Flight IIA Arleigh Burke-class destroyers, replacing their existing SLQ-32 equipment. A future SEWIP Block 4 with electro-optic and infrared detection capabilities has been proposed.
