Advanced jammers can attack multiple targets simultaneously

Engineers from the US Naval Air Systems Command are testing the new electronic warfare of the EA-18G Growler fighter. The new next-generation jammer Mid-Autumn Festival Belt System (NGJ-MB) has excellent display effect. The elements of the NGJ-MB Engineering Development Model (EDM) nacelle developed by Raytheon of El Segundo, California have performed basic functions for more than 400 hours and collected data through environmental electromagnetic waves (E3) and performance tests The term is three months. Test in the anechoic chamber of the Air Combat and Environmental Assessment Center. Naval Air Station Patuxent River will be ready soon. The data collected during this period also provides lessons that benefit the entire NGJ-MB test plan. Therefore, the second test phase can start flying shortly in the spring flight test and evaluation (VX) 23 squadron. The testing and integration of NGJ-MB on the EA-18G is part of the upgrade to the Block 2 “Growler” fighter. The new cabin will replace the current AN/ALQ-99 Tactical Jamming System (TJS), which will be used until The Vietnam War ended.

AN/ALQ-249 “NGJ-MB” is a high-capacity, high-performance electronic attack weapon system for the EA-18G “Growler”. Raytheon’s NGJ-MB solution provides innovative airborne electronic attack and destruction capabilities. The architecture and design of Raytheon NGJ-MB have the ability to operate in a wide range, attack multiple targets at once and use advanced jammer technology. The technology can also be applied to other tasks and platforms. The new portable jammer Pod will face increasingly complex threats that require electronic air strikes to be more complex than ever, thereby improving accuracy, performance, responsiveness and directionality.

ALQ-249 NGJ-MB is developed by combining agility and high-performance beam encryption technology and the latest solid-state electronic technology, and provides a cost-effective open system architecture that can be used for future upgrades to this level. NGJ operates in the 509 MHz to 18 GHz frequency band, and is being developed in three different capacities, including LB, mid-band (MB) and high-band (HB). NGJ-LB (also called block/increment 2), NGJ-MB (block/increment 1) and NGJ-HB (block/increment 3) are specifically targeted at the low frequency band (100 MHz to 2 GHz). , The medium (2 GHz to 6 GHz) and wide band (6 GHz to 18 GHz) of the global threat spectrum.

AN/ALQ-249 is a pan-tilt-mounted system that integrates digital, software and electronic scanning network technology (EASA) to create an enhanced EA function that can disrupt and affect radar transmitters and hostile communications. The new cabin will handle the mission area under deep strikes and traffic jams, assist naval operations, assist in close combat, irregular war communications, and the use of unconventional weapons and battlefield aerial targets. It can also be used for interception and intrusion accompanying operations. NGJ aims to confuse and defeat surveillance radar technology and high-frequency deployment radar. The latter can be used to warn the defense of nearby enemy aircraft, while high-frequency deployment radar can be used by air defense systems to target and track and destroy attack aircraft, thereby making it chaotic. And fail. .

American fighter jets flying over Syria are within range of Russian S-400 and S-300 surface-to-air missiles. This situation shows how important it is to stop the enemy’s air defenses. One of the main tactics used by American pilots is radar jammers, which are the process of saturating enemy radars with false signals so that they cannot follow friendly aircraft and fire at them. The US Navy has relied on the ALQ-99 jammer system for nearly half a century. But the capabilities of enemy radars have been enhanced. The new system is crucial. Rayhteon’s engineers said that NGJ-MB can block anything being transmitted or received, as well as RF frequencies within the NGJ frequency range, including Russian S-300 and S-400 systems. NGJ-MB will quickly adapt its structure to improvements and future ground-to-air threats.
