Reliability issues with the Next Generation Jammer Mid-Band noted in last year's annual report by the Pentagon's chief weapons tester have continued to plague the system, according to a new report released last week.
While hardware was the main source of blame for delays within the program last year, software issues are now mostly at fault, according to the Office of the Director of Operational Test and Evaluation. While the Navy made “substantial progress” with the system, significant challenges found during initial operational test and evaluation -- which began in July 2024 -- remain, the report states.
The IOT&E period included a deployment of the system with Electronic Attack Squadron 133 in July 2024.
“Early reliability issues were predominantly hardware related, but after further development and implementation of fixes, the remaining issues appear to be mostly software centric,” according to the report. “Although data are still insufficient to fully assess the reliability of the system, data trends have been markedly improving, suggesting the potential for a strong positive reversal in the future.”
The NGJ-MB consists of two pods located under the EA-18G aircraft wings and is the first of three programs meant to replace the AN/ALQ-99 Tactical Jammer System that is currently used. The system reached initial operational capability in December 2024.
IOT&E is set to complete in the second quarter of fiscal year 2025, and a report by DOT&E will be published the following quarter.
In its annual report, DOT&E recommends the Navy perform “the most rigorous testing possible on open-air ranges,” continue to develop advanced test and training infrastructure and refine software development for NGJ-MB.
