The 2S40 Floks is a Russian wheeled self-propelled 120 mm mortar system. It uses a Ural-4320 6x6 truck chassis and has armored crew and ammunition compartments. The vehicle was first shown to the public during the Army-2016 exhibition. The main new feature of the vehicle is a semi-automatic rifled gun, which allows firing of all types of mortar mines and shells : the gun can fire like a howitzer and mortar, and also be used for direct fire. Manufacturer Rostec reported on 5 October 2023 that it had begun to deliver Floks systems to the Russian Armed Forces.
