Russia has likely launched hundreds of Iranian-manufactured unmanned aerial vehicles (UAVs) against Ukraine since September, Britain's Ministry of Defense said on in its daily intelligence update on November 23. It's also likely that Russia has nearly exhausted its current stock of Iranian-made weapons and will seek resupply, the ministry said. It said Russia is likely using the UAVs to make up for a "severe shortage" of cruise missiles, but that the strategy has not been effective, as most UAVs have been shot down.
