PATUXENT RIVER NAS, Md. \u2013<\/strong>\u00a0RTX Corp. will build 13 Next Generation Jammer Mid-Band (NGJ-MB) airborne\u00a0electronic warfare (EW)<\/a>\u00a0systems for U.S. Navy and Australian EA-18 Growler combat jets under terms of a $591 million contract announced in late November.<\/p>\n Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., are asking the RTX Raytheon segment in El Segundo, Calif., to build 13 NGJ-MB ship sets — nine for the Navy and four for the Royal Australian Air Force. Each aircraft has two ship sets.<\/p>\n Counter-radar<\/strong><\/p>\n The NGJ midband is an advanced electronic attack system that denies, disrupts, and degrades enemy communications and air-defense radar systems. It offers a combination of agile active electronically scanned arrays (AESA) and an all-digital back end. The contract includes spare parts, support equipment, and non-recurring engineering.<\/p>\n The NGJ-MB helps the Growler aircraft operate at long ranges, attack several different targets simultaneously, use advanced electronic jamming techniques, and incorporate rapid upgrades through a modular, open-systems architecture.<\/p>\n In September RTX Raytheon won a $192 million contract to upgrade the NGJ-MB system to counter new adversary RF and microwave threats. This upgrade will provide the NGJ-MB with additional frequency coverage.<\/p>\n Raytheon delivered the first NGJ-MB pod to the Navy for testing in July 2019. The technology also can be scaled to other missions and aircraft.<\/p>\n The NGJ\u00a0airborne<\/a>\u00a0jammer pod is replacing the 40-plus-year ALQ-99 jammer system on the EA-18G — a version of the Navy’s carrier-based two-seat F\/A-18F Super Hornet jet fighter-bomber that is modified specially for electronic warfare.<\/p>\n Airborne attack<\/strong><\/p>\n The EA-18G leads an airborne attack by disrupting enemy radar, communications, and computer networks with jamming signals and computer viruses. The aircraft also can destroy enemy radar installations with its AGM-88 High-speed Anti-Radiation Missiles (HARM).<\/p>\n Raytheon’s NGJ will integrate the most advanced electronic attack technology into the EA-18G, such as high-powered, agile beam-jamming techniques, and solid-state electronics to deny, degrade and disrupt enemy threats while protecting U.S. and coalition forces.<\/p>\n Raytheon\u2019s NGJ will provide airborne electronic attack and jamming capabilities, and will include cyber-attack capabilities that use the aircraft’s active electronically scanned array (AESA) radar to insert tailored data streams into enemy radar and communications systems.<\/p>\n The NGJ also will have an open-systems architecture for future upgrades. Raytheon will use its gallium nitride (GaN)-based AESA technologies for the NGJ design.<\/p>\n Open-systems architecture<\/strong><\/p>\n Eventually Raytheon engineers may modify the NGJ to install it aboard the F-35 joint strike fighter, unmanned aerial vehicles (UAVs), as well as to other manned aircraft in addition to the EA-18G.<\/p>\n The Navy also is developing the Next Generation Jammer Low Band (NGJ-LB) in an urgent effort to develop low-band tactical radar\u00a0jammers<\/a>\u00a0using existing technologies for low size, weight, and power consumption (SWaP) applications on the EA-18G Growler EW jet.<\/p>\n L3Harris Technologies in Melbourne, Fla., won a contract in late 2020 to design and build the NGJ-LB, which experts say will be useful in jamming low-band radar systems designed to detect stealth aircraft like the F-35 joint strike fighter. The NGJ-LB transmitter will fit in a pod on Station 6 of the EA-18G.<\/p>\n The system will enhance the performance of frequency coverage, effective isotropic radiated power, spatial coverage, spectral purity, and polarization; obtain existing contractor data related to transmitter group performance; and assess the potential to deploy an open-systems interim pod solution rapidly.<\/p>\n On this contract Raytheon will do the work in Forest, Miss.; McKinney, Texas; El Segundo, Calif.; Andover, Mass.; and Fort Wayne, Ind., and should be finished by January 2028.
