AN/ULQ-6
The AN/ULQ-6 was an electronic countermeasure (ECM) deception repeater and false-target generator used by the United States Navy, primarily on destroyers and frigates. It was often used in combination with the AN/WLR-1 countermeasures receiver, and both were replaced by the AN/SLQ-32 electronic warfare suite. The ULQ-6 was also used by the Brazilian Navy on Marcílio Dias and Mato Grosso-class destroyers, Royal Canadian Navy on Iroquois-class destroyers, Republic of Korea Navy on Chungbuk and Gangwon-class destroyers.
In accordance with the Joint Electronics Type Designation System (JETDS), the AN/ULQ-6 designation represents the 6th design of an Army-Navy electronic device for a general utility countermeasures special/combination system. The JETDS system also now is used to name all Department of Defense and some NATO electronic systems.
