US Weapons Accuracy Drops To 10% In Ukraine Due To Jamming

Many high-tech US weapons systems in Ukraine are now useless due to jamming signals by Russia.

Please consider Russian Jamming Leaves Some High-Tech U.S. Weapons Ineffective in Ukraine
Russia’s jamming of the guidance systems of modern Western weapons, including Excalibur GPS-guided artillery shells and the High Mobility Artillery Rocket System, or HIMARS, which can fire some U.S.-made rockets with a range of up to 50 miles, has eroded Ukraine’s ability to defend its territory and has left officials in Kyiv urgently seeking help from the Pentagon to obtain upgrades from arms manufacturers.
The success rate for the U.S.-designed Excalibur shells, for example, fell sharply over a period of months — to less than 10 percent hitting their targets — before Ukraine’s military abandoned them last year, according to the confidential Ukrainian assessments.
Six months ago, after Ukrainians reported the problem, Washington simply stopped providing Excalibur shells because of the high failure rate, the Ukrainian officials said, speaking on the condition of anonymity to discuss a sensitive security matter. In other cases, such as aircraft-dropped bombs called JDAMs, the manufacturer provided a patch and Ukraine continues to use them.
Russia’s invasion of Ukraine created a modern testing ground for Western arms that had never been used against a foe with Moscow’s ability to jam GPS navigation.
But even before the United States ceased deliveries, Ukrainian artillerymen had largely stopped using Excalibur, the assessments said, because the shells are harder to use compared with standard howitzer rounds, requiring time-consuming special calculations and programming. Now they are shunned altogether, military personnel in the field said.
A web of Russian electronic warfare systems and air defenses menace Ukrainian pilots, the documents said, adding that some Russian jammers also scramble the navigation system of planes. The Russian defense is so dense, the assessment found, that there are “no open windows for the Ukrainian pilots where they feel that they are not at gunpoint.”
HIMARS launchers were celebrated during the first year of Russia’s invasion for their success in striking ammunition depots and command points behind enemy lines.
But by the second year, “everything ended: the Russians deployed electronic warfare, disabled satellite signals, and HIMARS became completely ineffective,” a second senior Ukrainian military official said. “This ineffectiveness led to the point where a very expensive shell was used” increasingly to strike lower-priority targets.

Defense One reports Another US Precision-Guided Weapon Falls Prey to Russian Electronic Warfare
A new ground-launched version of an air-to-ground weapon developed for Ukraine on a rapid timeline failed to hit targets in part because of Russian electro-magnetic warfare, Bill LaPlante, the Pentagon’s acquisition chief, said at an event held by think tank CSIS.
LaPlante suggested that Ukraine may no longer be interested in the weapon. “When you send something to people in the fight of their lives that just doesn’t work, they’ll try it three times and they’ll just throw it aside,” said LaPlante.
