The Ground Launched Small Diameter Bomb (GLSDB) is a weapon developed by Boeing and the Saab Group to allow Boeing's GBU-39 Small Diameter Bomb (SDB), originally developed for use by aircraft, to be ground-launched from a variety of launchers and configurations. It combines the SDB with the M26 rocket, enabling it to be launched from ground-based missile systems such as the M270 Multiple Launch Rocket System and M142 HIMARS.[9][10]
The weapon started initial mass production in 2023 and saw its first combat deployment by Ukraine in 2024 during the Russian invasion of the country. The performance was reportedly disappointing due to Russia's electromagnetic warfare capabilities, along with deficiencies in tactics, techniques, and procedures.
