烏克蘭對俄羅斯境內的空軍基地發動了戰爭以來最大規模的攻擊之一,目標從東西伯利亞到俄羅斯西部邊境。
As Drones Transform Warfare, NATO May Be Vulnerable
Assaults in Russia and Ukraine have shown major military powers that they are unprepared for evolving forms of warfare, and need to adapt.
An astonishing raid deep inside Russia rewrites the rules of war

Fighting the war in Ukraine on the electromagnetic spectrum
Drone operators and jammers are in a high-tech arms race

FOR SOLDIERS at the front, electromagnetic defences are as vital as air: invisible when present, and disastrous when not. In July Ukrainian troops in southern Donbas found this out the hard way. Abruptly, Russian drones switched frequencies, from standard 700-1,000 megahertz to 400-500 megahertz, blinding Ukraine’s electronic-warfare (ew) systems. The drones flew deep behind the lines, cutting off units and making supply routes impassable. Tens of Ukrainian military vehicles were destroyed daily in what Serhii Beskrestnov, a Ukrainian EW specialist, calls a “Russian safari”. Only when Ukraine understood what was happening, and secured new EW systems working at 500 megahertz, weeks later, were they able to stabilise the situation.

對前線的士兵來說,電磁防禦與空氣一樣重要:存在時看不見,不存在時則會帶來災難。 7 月份,頓巴斯南部的烏克蘭軍隊深刻地體會到了這一點。俄羅斯無人機突然將頻率從標準的 700-1,000 兆赫切換到 400-500 兆赫,使烏克蘭的電子戰系統失靈。無人機深入敵後,切斷部隊後路,使補給路線無法通行。烏克蘭電子戰專家謝爾蓋·別斯克雷斯特諾夫 (Serhii Beskrestnov) 稱其為“俄羅斯狩獵”,每天都有數十輛烏克蘭軍車被摧毀。直到幾週後,烏克蘭才了解到正在發生的事情,並獲得了以 500 兆赫茲運行的新型電子戰系統,才得以穩定局勢。
