MOSCOW, December 25. /TASS/. The Kalashnikov Company is shipping the first batch of upgraded Kub kamikaze drones to the customer, President Alan Lushnikov told Rossiya 24 TV channel.

"We have implemented Kub loitering munition with a higher-power warhead according to customer requirements. Trials have been successful and the first batch is being shipped to the customer at the given moment. It is a major step, as it was actually a new device," he said.

In November, Lushnikov said the Kalashnikov had increased Kub firepower and was working to extend the range.

Previous Kub carried a 3-kg payload. Maximum flight endurance was 30 minutes and the speed was 130 km/h.
