A new US-Swedish bomb may have already been pulled from Ukraine because it's useless against Russian jamming

  • Sophisticated US weapons are being jammed by Russian electronic-warfare units.

  • The Wall Street Journal reported that a relatively new US-Swedish bomb had been pulled from use.

  • Russia is able to scramble the GPS signals used to guide the weapons.

A new precision-guided US weapon is said to have been pulled from use by the Ukrainian military because Russia is taking it out using electronic warfare.

Ukrainian and Western officials told The Wall Street Journal the Ground-Launched Small Diameter Bomb, manufactured by Boeing and the Swedish company Saab, had failed and was no longer in use pending an overhaul.

The GLSDB is a guided bomb with a range of 94 miles, thanks to its small wings that extend from its body. In 2022, marketing materials for the bomb said its navigation system was "supported by a highly jamming resistance GPS."

As previously reported by Business Insider's Mia Jankowicz, Ukraine received the bombs in early February after months of requesting long-range munitions in the hope of hitting targets in areas such as Crimea.

In April, Defense One reported that Bill LaPlante, the Pentagon's acquisition chief, had said a ground-launched version of an air-to-ground weapon had become vulnerable to Russian electronic warfare. The publication said he was probably referring to the GLSDB.

"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," LaPlante said, according to the report, implying Ukraine no longer seemed interested in the weapon.

A month later, three sources familiar with the matter told Reuters the bombs' guidance systems were running into Russian jamming, causing many of the launches to miss their targets.

Boeing and the Ukrainian army didn't immediately respond to requests for comment from BI.

"We always have an ongoing dialogue with our partners, customers and end users regarding the use and development of our products and solutions, and of course this also applies to GLSDB. We naturally do not go into the content of these discussions or with whom we have a dialogue," a Saab spokesperson told BI.

The Journal reported that Russia had been able to remotely scramble the GPS signals used to guide weapons with its sophisticated electronic-warfare capabilities.

The GLSDB is one of several precision-guided US weapons Russia has been able to neutralize or reduce the effectiveness of using electronic warfare in Ukraine.

Russian electronic-warfare units have blunted the effectiveness of HIMARS-fired Guided Multiple Launch Rocket Systems and air-launched Joint Direct Attack Munitions.

BI reported in May that the US was researching ways to counter the problem should a war break out with a major military power.

Russia has seemingly been able to rapidly adapt to counter the threat of sophisticated US-supplied weapons.

In Ukraine, old-school artillery shells that aren't vulnerable to electronic warfare are playing a major role in the war of attrition on the front lines.

Ukraine's Western allies have struggled to provide enough shells, while Russia has massively increased its production of shells and is also sourcing artillery from its ally North Korea.

After Russia made advances earlier this year during a Ukraine aid block by Republicans in the US Congress, the resumption in the flow of aid has enabled Ukraine to hold off further advances, and the war has again become a stalemate.
