Russia has reportedly upgraded its KUB-BLA loitering munition for use in the battlefield against Ukraine. The Newsweek reported that the upgrade looks like the Russians strapped a sledgehammer to the belly of the drone with a modernised warhead. It quoted a SOFREP report claiming that the production lines for the ZALA KYB-UAV or 'CUBE' are in overdrive. The 'suicide' drone could prove to be a powerful new tool. It could help the Russian military in launching airstrikes against Ukraine. Watch for more details.
