Within weeks, the Russian army started to adapt, using its formidable electronic warfare capabilities. It managed to interfere with the GPS guidance and fuzes, so that the shells would either go astray, fail to detonate, or both. By the middle of last year, the M982 Excalibur munitions, developed by RTX and BAE Systems, became essentially useless and are no longer employed, Ukrainian commanders say.

A brand-new system, the Ground-Launched Small Diameter Bomb munition, manufactured by Boeing and Sweden’s Saab, has failed altogether after its introduction in recent months, in part because of Russian electronic warfare, Ukrainian and Western officials say. It is no longer in use in Ukraine pending an overhaul.

The Pentagon declined to discuss the performance of specific U.S. weapons systems, citing operational security.

The introduction of Western weapons there showed that what may have worked against Saddam Hussein’s army, the Taliban or Islamic State guerrillas won’t necessarily perform against a modern military like Russia’s or China’s.

“We have probably made some bad assumptions because over the last 20 years we were launching precision weapons against people that could not do anything about it,” said retired Lt. Gen. Ben Hodges, a former commander of the U.S. Army in Europe. “Now we are doing it against a peer opponent, and Russia and China do have these capabilities.”
