“Epic detonation” in Ukraine: speculation about new super rocket. Ground Launched Small Diameter Bomb (GLSDB) at the center of the speculation.
The GLSDB is a weapon developed in a joint venture between the American company Boeing and the Swedish group Saab Group. It combines the GBU-39 air-to-ground bomb with the ground-based M26 rocket. The rocket assembled in this way is said to have a range of 90 miles, or around 145 kilometers.
