Russian engineers in the military-industrial complex upgraded FAB-250 high-explosive aerial bombs (the bombs are in service with the Russian Aerospace Forces) to the level of precision-guided munitions, a source in the industry told TASS.
"As part of the FAB-250 bomb upgrade, we installed the inertial navigation system on winged platforms. When it gets uncoupled from the aircraft at a speed of 800-900 kilometres per hour, the bomb then glides for up to 80 kilometres," the source told the news agency.
Su-34 fighter-bombers use precision-guided munitions during the special military operation in Ukraine, the source said.
Representatives for the Russian defence industry have not provided an official confirmation to the above information, TASS noted.
