The US gave up sending Ukraine Excalibur guided artillery shells costing $100,000 because they rarely hit their target, report says

• The US halted deliveries of GPS-guided Excalibur shells to Ukraine due to high failure rates.
• Russia had achieved success in jamming of US-supplied weapons, reports said.
• Classified reports revealed the Excalibur shell strike success dropped from 55% to 6% last summer.

The US halted deliveries of Excalibur extended-range guided artillery shells to Ukraine after Kyiv reported high failure rates, anonymous Ukrainian officials told The Washington Post.

Six months ago, Ukraine told Washington that Russia's jamming of the guidance systems in several US-supplied weapons had eroded its ability to defend its territory, the officials told the Post.
