 Putin demands more kamikaze drones against Ukraine. Russian President Vladimir Putin ordered Rostec to increase the production of cub and land-set drones. Manufacturers have promised me that they will increase the amount of production. They are fulfilling this promise. But more needs to be increased. He said at a meeting with the head of Rostec, Sergei Chemezov. Putin noted the high efficiency of these drones. The blow is powerful. Any equipment, including foreign-made equipment, not only burns, but ammunition also explodes. He noted at a meeting with Chemezov, Putin said that the state corporation needed to increase the production of the latest types of weapons in percentage terms. He explained that he was talking in particular about the T-90 pro-Riv tanks and aircraft systems. Cub and land-set are small size kamikaze drones. Rostec has said last year that Russia's kamikaze drones, cub and land-set are widely used in combat operations in Ukraine and have successfully demonstrated their properties in combat conditions. The drones are mainly used to hit distant ground targets. The cub UAV carries a three kilogram warhead. Its maximum flight duration is 30 minutes and speed 130 kilometers an hour. The land-set UAV is equipped with several types of guidance systems, coordinate, optoelectronic and combined. The drone has a television communication channel that transmits an image of the target which allows to get a confirmation the target has been hit. The complex is capable of destroying targets within a radius of up to 40 kilometers. Its maximum takeoff weight is 12 kilograms. Putin's order comes as drone warfare intensifies between Moscow and Kiev, with both sides using UAVs to strike the heartland of the other side, usually targeting vital infrastructure. Rostec enterprises produce 90 percent of the equipment that the armed forces use in Ukraine.
