The new electronic attack pod matches advanced electronic-attack technology developed by raytheon, that combines high-powered, agile, beam-jamming techniques with cutting-edge, solid-state electronics. Earlier this month the Navy awarded the Raytheon Company a sole source contract worth one billion US$ for Engineering and Manufacturing Development (EMD) of the baseline NGJ system. Under the contract Raytheon will deliver 15 Engineering Development Model pods for mission systems testing and qualification, and 14 aeromechanical pods to be used for for airworthiness certification, functionality tests and integration with other systems, and carriage on the host aircraft. The NGJ contract, awarded in the second quarter and announced on April 13th, also covers designing and delivering simulators and prime hardware to government labs and support for flight-testing and government system integration. The NGJ Critical Design Review is scheduled for early to mid-2017. The new pod will enter service toward the 2020s, fielded with the F/A-18G Growlers of the US Navy. The Navy plans to acquire 138 pod sets through the program. The Mid and High band pods will be identical, while the Increment 2 ‘Low Band’ will consist of a larger, centerline-mounted pod, containing the larger apertures and emitters handling low frequency signals. The AN/ALQ-99 Tactical Jamming System is currently integrated on the EA-18G GROWLER and EA-6B Prowler aircraft operated by the US Navy and Marine Corps. Both aircraft are currently in service, but only the F/A-18G is expected to be in service beyond the mid 2020s. Therefore, the new pod is developed exclusively for the Growler. While the ALQ-99 was integrated on EA-6B, EF-111 and F/A-18G, the Next Generation Jammer pod is designed exclusively for the F/A-18G Growler. Such pods often use multiple AESA antennae facing fore and aft, covering a hemisphere of 360 degrees.

Although the NGJ will cover the same frequencies, it will better address current advanced and emerging threats alike, as well as the growing numbers of threats. Employing the latest digital, software-based and Active Electronically Scanned Array technologies, and Gallium Nitride (GaN) technology, NGJ will be able to dwell much higher power levels, directed simultaneously against many threats in different directions. NGJ will have the necessary power and digital techniques to counter increasingly advanced and sophisticated adversary electronic warfare search, surveillance, and targeting-radars and communications systems. The Navy expects to field the new pod by 2019, with initial operational capability expected by 2021.
