美国空军 B-1B 轰炸机的 ECM 更新计划将于明年初正式开始实施。估计其总费用为7.5～10亿美元,使它成为美国目前正在得到经费的最大的单项 EW 计划。实施该改进计划意在克服伊顿-AIL ALQ-161防御性航空电子系统的缺点,并使所有的 B-1飞机都有通用的“O 型”(“Mod O”)布局结构。极为重要的是,将改进最初为在前苏联上空执行低空核轰炸飞行任务而设计的那些航空电子系统,以使 B-1能在高空和低空及以不同飞行速度对付各种地区性防空威胁。
The ECM B-1B bomber’s ECM renewal plan will be officially put into effect early next year. The estimated total cost is between $ 7.5 billion and $ 1 billion, making it the single largest single EW program currently being funded in the United States. The improvement program was designed to overcome the shortcomings of the Eaton-ALQ-161 defensive avionics system and to provide a common “Mod O” layout for all B-1 aircraft. Crucially, those avionics systems originally designed to carry out low-level nuclear bombing missions over the former Soviet Union will be improved so that the B-1 can deal with various regional air defense threats at high and low altitudes and at different speeds.
