据c4isrnet网2020年6月3日报道，在年度国防采办报告中，美国会政府问责局（ GAO ）指出，海军新一代机载电子干扰系统中频段关键技术在技术成熟度、设计稳定性、软件及网络安全等方面存在问题。
海军ALQ-99吊舱更新计划分三段，覆盖电磁频谱中、低和高三部分，旨在使该电子战平台能更快地捕获更远目标。
吊舱将配备EA-18G“咆哮者”(Growlers)电子攻击机，海军2016年将中频段吊舱研发授予雷神公司，已提出低段吊舱报价，而高段时间表尚不明朗。
GAO 发现，中段计划关键技术尚不成熟，设计稳定性差,离最佳运行要求尚有很大差距，称“直到关键技术完全成熟，项目设计面临变更风险”。
项目尽管2016年4月已进入系统开发阶段，2019年11月启动了吊舱7项关键技术开发和地面试验，但直到今年3月，项目办仍未拿出推进关键技术完全成熟、组织系统集成和飞行测试的计划。
据今年2月美国防部预算计划显示，美海军计划2021财年为中段计划提出1.766亿美元采购预算和4.776亿美元研究发展预算。
针对中段吊舱软件开发的问题，GAO报告引用项目官员的说法，称软件开发比预期困难得多，存在较大风险。
此外，鉴于吊舱依赖“咆哮者”的软件，而该软件也已改进，因此该计划也必须相应改进。
Watchdog discovers problems with Navy jammer
Congress’ watchdog agency, the Government Accountability Office, found that the Navy has yet to fully demonstrate critical technologies in the mid-band portion of the service’s future airborne electronic jamming system.
In its annual report on defense acquisitions, the GAO pointed to technology maturity, design stability and software and cybersecurity problems with the Next Generation Jammer-mid band pod.
The Navy’s plan to replace the ALQ-99 jamming pod has been broken up into three pods covering three portions of the electromagnetic spectrum: mid, low and high.

The Navy’s new three-part electronic warfare platform will have the ability to prosecute more targets more quickly from further away.
The pods will be outfitted to EA-18G Growlers. The Navy awarded the mid band pod to Raytheon in 2016. Bids are out for the low band pod. The timeline for high band is unclear at this time.
The GAO found that the mid band program had yet to fully demonstrate the maturity of its critical technologies or stability of its design, which is inconsistent with best practices.
“Until the program fully matures its critical technologies – by demonstrating each in a final form, fit, and function within a realistic environment – the program’s design faces risk of change,” GAO said.
However, the program plans to demonstrate this technology ahead of its planned production decision in September. That milestone is for low rate initial production contract.
Despite entering system development in April 2016 with seven critical technologies and ground testing of the pod beginning in November 2019, the program office didn’t plan to have these critical technologies fully mature, integrated and flight tested until March.
GAO conducted its review in January.
A news release from Naval Air Systems Command in mid-March said the mid band pod completed a portion of developmental testing and that the pod was expected to enter flight testing this spring.
GAO also noted that in April 2017, the program discovered design deficiencies with the pod’s structure at critical design review. Those problems contributed to a one-year schedule delay and a more than $400 million increase in development cost.
According to DoD budget documents released in February, the Navy planed to spend $176.6 million in procurement dollars and $477.6 million in research and development dollars for fiscal year 2021 for the mid band program.
GAO reported issues with the mid band pod’s software development, citing program officials identifying it a risk because the software effort was more difficult than expected. Those officials noted it has been difficult to find and hire government and contractor staff with necessary expertise to perform the work on time.
Moreover, since the pod is dependent upon the Growler’s software, which have evolved, the program has had to evolve in kind.
An evaluation for cybersecurity vulnerabilities was planned to be completed in April, the report said. NAVAIR told GAO that it plans to deliver a single software product to the fleet, though, that process takes 13 months to develop.
