Russia has announced that it will begin to mass-produce a self-designed drone next year, as the United States and Europe pledged to provide more air defense equipment to Ukraine.

Russian state news agency TASS reported on Tuesday that the country will begin production of the new drone designed by the Kartsev Institute of Computing to disperse crowds and to gather intelligence on the battlefield next year.

The Shershen is a hexacopter drone that functions in much the same way as a typical quadcopter drone, though it uses both ultrasound and infrasound to disperse crowds, and is designed for use in a domestic security context.

"We are planning to enter serial production of the Shershen after the New Year. From mid-December to January, we will already be able to show the hexacopter in action," Vitaly Dolgov, head of the institute's research laboratory for unmanned vehicles, told TASS.

The Shershen is also battlefield capable and comes equipped with radar jamming technology as well as a camera for intelligence gathering.

The rollout comes amid the effective use of drones by both sides in the ongoing special military operation in Ukraine, which has been increasingly shaped by unarmed aerial vehicles.

The Izvestia newspaper reported that oil tanks near Russia's border with Belarus and Ukraine caught fire early on Wednesday, which may have been caused by an unidentified munition dropped from a drone.

The fire comes a day after Russian regions bordering Ukraine reported one of the widest spates of shelling attacks on their territory since the start of Moscow's military operation.
