How Electronic Warfare Shapes the Russia-Ukraine War (apnews.com) 93

"On Ukraine's battlefields, the simple act of powering up a cellphone can beckon a rain of deathly skyfall," reports the Associated Press. "Artillery radar and remote controls for unmanned aerial vehicles may also invite fiery shrapnel showers."

And the same technology can also be used to target navigation, guidance, and communications systems "to blind and deceive the enemy." 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.... 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. [A former U.S. Army commander tells the AP "What we're learning now is that the Russians eventually turned it off because it was interfering with their own communications so much."] 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.

Later the article says Ukraine's Aerorozvidka has also modified camera-equipped drones "to pinpoint enemy positions and drop mortars and grenades. Hacking is also used to poison or disable enemy electronics and collect intelligence."

So far Ukraine has captured "captured important pieces of hardware — a significant intelligence coup — and destroyed at least two multi-vehicle mobile electronic warfare units." They've been aided by technology and intelligence from NATO members (including from satellites and surveillance aircraft). But the article also calls Elon Musk's Starlink "a proven asset." Its more than 2,200 low-orbiting satellites provide broadband internet to more than 150,000 Ukrainian ground stations. Severing those connections is a challenge for Russia. It is far more difficult to jam low-earth orbiting satellites than geostationary ones.

Musk has won plaudits from the Pentagon for at least temporarily defeating Russian jamming of Ukrainian satellite uplinks with a quick software fix. But he has warned Ukrainians to keep those terminals powered down when possible — they are vulnerable to geolocation — and recently worried on Twitter about redoubled Russian interference efforts.

The article points out that to "stay nimble," Ukraine is also using cutting-edge technologies including software-defined radio and 3D printing.

  • The problem with drones is that their radio signal can be jammed (goodbye video feed). Of course, a radio jammer is a good candidate for an anti-jammer missile [wikipedia.org]. But then the drone can be targeted with an anti-radiation missile, too.

    Ultimately humans will not be replaced by drones until we solve the radio problem.

      A few years ago, a computer beat a 9-dan Go master.

      Don't worry about the drones. They'll be fine without us.

      • ok, but that's still future theoretical. It's not here today. It likely won't be here for a decade at least.

    • Of course, a radio jammer is a good candidate for an anti-jammer missile [wikipedia.org].

      Question: How much do jammers cost compared to anti-jammer missiles?

      • Depends how much range you want them to have. This is true for both jammers and missiles.

        Things are still being developed of course, but I would guess that they will cost about the same at the end of the day.

      The problem with jammers is that they're easily defeated. High gain antennas blind the receiver to the jammer unless the jammer is in the receiver antenna lobe.

      Another problem with jammers is that they're easy to detect and thus vulnerable to attack.

      • They fly out, take photos, fly back.

        Just dead reckoning would get them over targets.

        And the AI is getting much better. Certainly to navigate over terrain. Not sure about identifying targets in the presence of decoys.

    • Commercial drone that stays on known wifi band is easy to jam. Military drone does not stay on the same frequency but keeps hopping in a way unpredictable to outsiders. So it's not trivial at all to jam military UAV.

    In the olden days the sergeant said: "Don't light a cigarette, the sniper will get you."

    Now he says: "Don't troll on the internet, the missile will get you. And us."

  • keep those terminals powered down when possible

    UUCP is back, baby!

  • An expanded NATO with Finland and Sweden will have even more tools.

    The sooner Russia surrenders, the better for them.

If you do something right once, someone will ask you to do it again.
