Ground Launched Small Diameter Bomb (GLSDB)

The Ground Launched Small Diameter Bomb (GLSDB) is a weapon made by Boeing and the Saab Group, who modified Boeing's GBU-39 Small Diameter Bomb (SDB) with the addition of a rocket motor. Initial testing began in 2015. If supplied to Ukraine in 2023, this would mark the weapon's first export and use in combat. The weapon is launched from ground-based missile systems such as the M270 Multiple Launch Rocket System and M142 HIMARS.
