The United States has upgraded the Ground-Launched Small Diameter Bombs (GLSDB) to counter Russian jamming and is set to “reintroduce” them onto the battlefield in Ukraine within days, according to a Reuters report.
The GLSDB, jointly developed by Boeing and SAAB AB, combines the GBU-39 Small Diameter Bomb with the M26 rocket motor, creating a weapon with a range of approximately 100 miles (161 kilometers).
The administration of former President Joe Biden sent an undisclosed number of GLSDB units to Kiev, but it has been “months” since Ukrainian forces last used the bomb against Russia after it proved ineffective last year, sources told Reuters.
Russia’s electronic warfare capabilities rendered precision-guided Western munitions – including GLSDB and GPS-guided Excalibur artillery shells – ”useless,” the Wall Street Journal reported in July. With their guidance systems scrambled, some of these weapons were reportedly retired within weeks of being deployed.
