The US Navy has started the final Demonstration of Existing Technologies (DET) test period for the Next Generation Jammer Low Band (NGJ-LB) capability, which is part of a larger NGJ weapon system, at Naval Air Station Patuxent River in Maryland.

NGJ-LB tests are being conducted at the Air Combat Environmental Test and Evaluation Facility and the Facility for Antenna and RCS Measurement (FARM).

Under the 20-month DET contract, the US Navy collaborated with multiple industry partners to conduct the test.

NGJ-LB Airborne Electronic Attack Systems (PMA-234) Programme Manager Captain Michael Orr said: “This is an exciting time for the team. It’s the culmination of almost two years in the making.

“I’m very proud, despite the current Covid-19 environment, that our collective government and industry teams continue to focus on delivering fleet capability while also maintaining health and safety protocol.”

In October 2018, Northrup Grumman and L-3Harris Technologies won two DET contracts. Under the contracts, both companies have completed eight significant test events.

NGJ-LB is part of a larger NGJ weapon system, which will replace the legacy ALQ-99 Tactical Jamming System (TJS) currently used for Airborne Electronic Attack on the EA-18G Growler aircraft.

Orr added: “NGJ-LB is the next step in the evolution of Airborne Electronic Attack that is needed to meet current and emerging electronic warfare gaps, and our team is dedicated to delivering this capability to the fleet as quickly as possible.”

Earlier this month, US-based structure supplier CPI Aero joined the NGJ-LB Capability Block 1 (CB-1) solution team. The team is being led by Northrop Grumman, which submitted its proposal for the project in January this year.
