The Russian Thunder drone, a wingman of the Su-57 aircraft. The Russian attack drone "Thunder" from the Kronshtadt company was shown again at the Army-2024 forum. This is the second, presumably simplified version of the Thunder drone, which was first shown in 2020. The simplification was probably made to reduce the cost of the project and to attract greater interest from potential customers. Now the UAV has a conventional power plant without a flat nozzle. When viewed from the side, the Thunder drone began to look like the Soviet Tu-141 Strizh UAV, which is now in service with Ukraine. It is worth noting that the Ukrainian Tu-141, due to an error, was able to fly unhindered over Romania, Hungary and Croatia. Perhaps based on this fact, they decided to simplify the design of the Russian Thunder drone. The Grom UAV is designed to operate as a wingman in the forward attack echelon in cooperation with manned aircraft, presumably with the Su-35 or Su-57. The UAV is designed to destroy ground targets in tactical and operational-tactical depth and perform reconnaissance missions. The Grom UAV has underwing and intra-fuselage weapon suspension points. The drone uses Kh-38 air-to-surface guided missiles, Izdeliye 85 missiles, as well as KAB-250 and KAB-500 guided aerial bombs. The maximum speed of the Grom UAV is 1,000 km/h, cruising speed is from 650 to 800 km/h, flight altitude is up to 12,000 meters, combat radius is up to 700 km. The takeoff weight of the drone is 7 tons, the payload is 2 tons.
