Russian jamming in Ukraine causing interference with U.S. weapons

American-made precision-guided weapons supplied to Ukraine have faced challenges on the battlefield due to Russian jamming efforts, according to Ukrainian commanders and military research. The Excalibur and Ground Launched Small Diameter Bomb (GLSDB) initially performed well but lost effectiveness as Russian defenses adapted.

The Ukrainian military ceased using these weapons after reports revealed their diminished accuracy. The Excalibur, a 155 mm guided artillery shell, and the GLSDB were particularly affected by Russian jamming, which disrupted their GPS targeting systems.

Ukrainian officials highlighted the importance of feedback to Western partners on weapon performance against a sophisticated enemy like Russia. The research collected data on the usage of these weapons, showing a significant drop in successful strikes over time.

Ukrainian commanders confirmed the challenges faced with these weapons and the need to resort to less accurate alternatives. The U.S. Department of Defense acknowledged the evolving electronic warfare threat posed by Russia and emphasized the need for continuous assessment and rapid solutions.

Experts suggested countermeasures to combat jamming, including eliminating the source of interference and using alternative guidance systems. The experience with the Excalibur highlighted the importance of software adaptability in modern warfare.

The situation in Ukraine serves as a reminder of the constant evolution of warfare and the need for innovative and agile defense strategies. The performance of these weapons has significant implications for future weaponry and the ongoing conflict in Ukraine.
