The Tactical Missiles Corporation has developed air-to-surface missiles for this drone, prepared the Izdeliye 85 guided missile, as well as KAB-250 and KAB-500 guided bombs.^[4] The Grom drone will be capable of not only operating with its own weapons, but also controlling a swarm of 10 units of Molniya strike drones launched from another carrier.^[5]
