Boeing weapons don't work in Ukraine

U.S.-provided precision-guided munitions have failed in mission after mission in Ukraine, taken down by Russian electronic warfare. On Wednesday, the Pentagon revealed the latest casualty.

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.

The weapon LaPlante is referring to is very likely the Ground-Launched Small Diameter Bomb (GLSDB) based on his description, according to Bryan Clark, a senior fellow at the Hudson Institute.

A Boeing spokesperson did not confirm that LaPlante was referring to GLSDB, but said the company is “working closely with the [Defense Department] on spiral capability improvements to the ground-launch SDB system.” Spiral capability improvements refers to an iterative software development process.

The GLDSB boasts a range of 90 miles—double the range of the Guided Multiple Launch Rocket System (GMRLS) missiles Ukraine previously used to wreak havoc on Russia’s logistic centers. Funding for the weapon was approved in February 2023, and Ukraine was reportedly using the weapon by February 2024.

The weapon relies on GPS to navigate to its targets. It also has an inertial navigation system, which navigates to a target by estimating its position through the use of accelerometers and other devices.

But it is not the first GPS-guided weapon to fall afoul of Russian electronic warfare. ...

In congressional testimony in March, Hudson Institute Senior Fellow Daniel Patt said the targeting system for the GPS-guided Excalibur round “dropped from 70 percent effectiveness to 6 percent effectiveness over a matter of a few months as new EW mechanisms came out” in Ukraine. Patt cited the work of Jack Watling, an expert at think-tank RUSI who has traveled to Ukraine multiple times to interview Ukrainian commanders.
