KYIV, Ukraine (AP) — On Ukraine’s battlefields, the simple act of powering up a cellphone can beckon a rain of deathly skyfall. Artillery radar and remote controls for unmanned aerial vehicles may also invite fiery shrapnel showers.
This is electronic warfare, a critical but largely invisible aspect of Russia’s war against Ukraine. Military commanders largely shun discussing it, fearing they’ll jeopardize operations by revealing secrets.
Electronic warfare technology targets communications, navigation and guidance systems to locate, blind and deceive the enemy and direct lethal blows. It is used against artillery, fighter jets, cruise missiles, drones and more. Militaries also use it to protect their forces.
It’s an area where Russia was thought to have a clear advantage going into the war. Yet, for reasons not entirely clear, its much-touted electronic warfare prowess was barely seen in the war’s early stages in the chaotic failure to seize the Ukrainian capital of Kyiv.
It has become far more of a factor in fierce fighting in eastern Ukraine, where shorter, easier-to-defend supply lines let Russia move electronic warfare gear closer to the battlefield.
“They are jamming everything their systems can reach,” said an official of Aerorozvidka, a reconnaissance team of Ukrainian unmanned aerial vehicle tinkerers, who spoke on the condition of anonymity because of safety concerns. “We can’t say they dominate, but they hinder us greatly.”
A Ukrainian intelligence official called the Russian threat “pretty severe” when it comes to disrupting reconnaissance efforts and commanders’ communications with troops. Russian jamming of GPS receivers on drones that Ukraine uses to locate the enemy and direct artillery fire is particularly intense “on the line of contact,” he said.
