据spacewar网2020年6月4日报道,美国会问责局(GAO)本周发布的最新报告提出,美海军杰拉尔德·福特号新型超级航母两大系统仍存在重大技术问题,称“尽管关键技术日趋成熟,海军仍在努力证明关键系统的可靠性,包括电磁飞机发射系统 (EMALS); 先进飞机制动系统 (AAG);以及双波段雷达 (DBR)。”

该航母一直存在成本超支和技术问题,尤其是弹药升降机。今年四月,福特号配备的第五个武器升降机已通过认证,但迄今为止没有一部投入使用。

本周初,海军宣布航母已从舰船运行转向准备海上作战状态,包括将武器从下层甲板移到飞行甲板。

GAO报告提到,2019年9月, 海军将CVN78的成本上限增加1.97亿美元,达132亿美元,部分原因是修复电梯缺陷。

海军力争今年春天前完成所有电梯工作。

USS Ford still has major technical problems, says GAO report

The USS Gerald Ford, the U.S. Navy’s new, supercarrier still has major technical problems in two of its systems, according to a new report from the Government Accountability Office.

“Despite maturing its critical technologies, the Navy is still struggling to demonstrate the reliability of key systems, including the electromagnetic aircraft launch system (EMALS); Advanced Arresting Gear (AAG); and dual band radar (DBR),” said the report, which was released this week.

Intended to replace the Nimitz-class carriers, the Ford has been troubled by cost overruns and technical problems, particularly involving its munitions elevators.

The Navy certified a fifth weapons elevator aboard the Ford in April, but according to the GAO, none of the weapons elevators are currently operational, which means the elevators still can’t bring munitions to the flight deck from the lower decks.

Earlier this week, the Navy announced that the ship has moved from aircraft carrier operations to preparing for maritime combat, including moving inert weapons from a lower deck to the flight deck.

The GAO report notes that in September 2019, the Navy increased the CVN 78 cost cap by $197 million to $13.2 billion — in part to fix deficiencies in the elevators.

The Navy is now aiming to complete all elevator work by this spring, the GAO said.
