2S40 Floks
The 2S40 Floks is a Russian 120 mm wheeled self-propelled artillery system on an armored Ural-4320 6x6 chassis, built to combine mortar, howitzer-style indirect fire, and direct-fire roles. Its documented Russia-Ukraine War appearance is notable because Ukrainian sources reported FPV-drone strikes against the new system soon after Rostec announced deliveries to Russian forces in October 2023.

Related Weapon Systems
152 mm SpGH DANA152 mm wheeled self-propelled gun-howitzerThe 152 mm SpGH DANA is a Czechoslovak wheeled self-propelled gun-howitzer built around a Tatra 8x8 chassis, a semi-automatic loading system, and a 152 mm gun compatible with Soviet-pattern ammunition. In Ukrainian service, Czech-supplied DANA and DANA M2 systems add mobile tube artillery that can shoot and displace faster than towed 152 mm guns while still using ammunition types already present in Ukraine's artillery inventory.
2S23 Nona-SVK120 mm wheeled self-propelled gun-mortarThe 2S23 Nona-SVK is a Russian 120 mm self-propelled gun-mortar that adapts the Nona artillery system to a BTR-80 8x8 armored chassis. Its rifled 2A60 weapon can provide direct or indirect fire with mortar bombs and artillery projectiles, giving motorized units a compact battalion-level fire-support vehicle. In the Russia-Ukraine War, Russian 2S23s have appeared in battlefield reporting and visually confirmed loss records, including destroyed and captured vehicles.
2S43 Malva152 mm wheeled self-propelled howitzerThe 2S43 Malva is a Russian 152 mm wheeled self-propelled howitzer that mounts a 2A64 gun on an 8x8 BAZ chassis, trading the turreted protection of tracked systems for road mobility, lower operating cost, and faster deployment. It is part of Russia's newer wheeled artillery family and has been documented with Russian forces during the Russia-Ukraine War.
Zuzana 2155 mm wheeled self-propelled howitzerZuzana 2 is a Slovak 155 mm/52-caliber wheeled self-propelled howitzer built around an automated loading system and a Tatra 8x8 chassis. Its NATO-standard ammunition, long-range indirect-fire role, and documented deliveries to Ukraine make it part of the Western artillery support package used to strengthen Ukrainian tube artillery in the Russia-Ukraine War.
2S1 Gvozdika122 mm tracked self-propelled howitzerThe 2S1 Gvozdika is a Soviet 122 mm tracked self-propelled howitzer built around the 2A31 gun on an amphibious armored chassis derived from the MT-LB family. In the Russia-Ukraine War it remains a common short-to-medium-range artillery system for both Russian and Ukrainian forces, combining mobility, indirect fire, and widespread 122 mm ammunition compatibility.
2S19 Msta-S152 mm tracked self-propelled howitzerThe 2S19 Msta-S is a Soviet-designed, Russian-produced 152 mm tracked self-propelled howitzer built to replace earlier 2S3 and 2S5 artillery systems with longer-range fire, automated laying variants, and armored cross-country mobility. In the Russia-Ukraine War it appears as a Russian tube-artillery system and as captured equipment operated by Ukrainian units, making it part of the conflict's counter-battery and trophy-equipment record.Sources
