Electronic warfare (EW) experts at Harris Corp. will provide the U.S. Navy and Australian air force with 86 sophisticated EW jamming systems designed to protect combat aircraft from incoming radar-guided missiles. Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., have announced a $161 million order to the Harris Corp. Electronic Systems segment (formerly Exelis Inc.) in Clifton, N.J., to build 86 full-rate production lot 15 AN/ALQ-214A(V)4/5 integrated defensive electronic countermeasures jammer systems for the F/A-18C/D and F/A-18E/F Hornet and Super Hornet jet fighter-bombers. The AN/ALQ-214A(V)4/5 is an electronic jammer component of the integrated defensive electronic counter measures system (IDECM) from a joint venture of Harris and BAE Systems. It protects F/A-18 fighter-bombers from radar-guided surface-to-air and air-to-air missiles by jamming the enemy missile guidance systems. The ALQ-214 component of the IDECM EW system has been delivered to the U.S. Navy, as well as to the Royal Australian Air Force for contemporary versions of the Boeing F/A-18 fighter-bomber. The system blends sensitive receivers and active countermeasures to form an electronic shield around the aircraft, Harris officials say.
