Ukraine reportedly uses GLSDB munitions for the first time

Ukrainian forces have likely received and successfully used precision-guided Ground Launched Small Diameter Bombs (GLSDB) against Russian troops for the first time, Defence Express media outlet reported on Feb. 14. Analysts reviewed video footage released by Russian forces, which showed remnants of the missile used in attacks on Russian-held areas. The experts identified an unusual square part with control surfaces and a barcode, believed to be the tail section of the GBU-39/B Small Diameter Bomb (SDB). The SDB is part of the GLSDB system, coupled with a rocket engine repurposed from an M26 unguided rocket artillery munition. The video displays only the ordnance's tail, suggesting it could be the first combat deployment of GLSDB. GLSDB was specially procured for Ukraine by the U.S. government through the USAI (Ukraine Security Assistance Initiative) program. On Jan. 30, Politico reported that GLSDB munitions could be shipped to Ukraine as early as Jan. 31. These state-of-the-art long-range munitions developed by Boeing and Saab are not yet part of the U.S. arsenal, the report added. With an extended range of 94 miles (150 kilometers), GLSDB glide bombs could become an alternative to ATACMS ballistic missiles Kyiv has long sought to get from Washington. For targeting, the GLSDB utilizes an inertial navigation system and GPS. Once launched, the bomb deploys wings and effectively glides to its target.
