EXCLUSIVE: New documents show how Russian jamming has rendered almost useless some high-tech U.S. weapons in Ukraine

By ⁦Isabelle Khurshudyan⁩ and ⁦Alex Horton⁩ washingtonpost.com/world/2024/05/…

The Ukrainians have used air launched small diameter bombs for months now, which was previously unreported. Their hit rate is pretty good, according to the documents, much better than the munitions modified to launch from the ground.

Weapons can be effective only until the enemy adapts, and in Ukraine, Russia has proven adept at jamming U.S. guided munitions. Details on confidential assessments w/ Isabelle Khurshudyan washingtonpost.com/world/2024/05/…

“Russia’s jamming of the guidance systems of modern Western weapons…has eroded Ukraine’s ability to defend its territory and has left officials in Kyiv urgently seeking help from the Pentagon…”

Great scoop from Isabelle Khurshudyan:

'One U.S. weapon used by aircraft, the GBU-39 small-diameter bomb, has proved resilient to jamming, according to the confidential documents. Nearly 90 percent of dropped bombs struck their target...But the modified...GLSDB, proved ineffective compared to those launched from

What an amazing fight 🥊

I shared observations on Russia’s initial operations in Kharkiv in this story by ⁦Mary Ilyushina⁩. My impression is that these early efforts show learning in how they phase actions and disperse forces, inside border areas of Russia and in Ukraine. washingtonpost.com/world/2024/05/…

“In a tactic similar to one Russian forces used to capture the Ukrainian city of Bakhmut last year, groups of infantry have attacked in waves. But the groups now have more than 15 soldiers, Obolyenskyi said — twice as many as in Bakhmut.” washingtonpost.com/world/2024/05/…

Russia seems to have made a counter-Starlink breakthrough & used it on the eve of its Kharkiv attack this month. “Its Starlink devices…failed, the first time it was knocked out completely for them since Russia’s invasion in February 2022” washingtonpost.com/world/2024/05/…

If you want to know why the Russians were able to gain so much ground in Kharkiv Oblast, read the below.

'We didn’t see how they were moving, we only worked through radio or through phones,' Artist, a 53-year-old sergeant, said. The drone feeds “simply disappeared'.

Brigade’s Starlink devices — satellite internet the Ukrainian military relies on for basic communication — failed, the first time it was knocked out completely for them since Russia’s invasion in February 2022.
“We were left at a certain point completely blind,” commander said.
