The 2S1 Gvozdika (Russian: 2С1 «Гвоздика», "Carnation") is a Soviet self-propelled howitzer introduced in 1972 and is in service in Russia and other countries as of 2025. It is based on the MT-LBu multi-purpose chassis, mounting a 122 mm 2A18 howitzer. "2S1" is its GRAU designation. An alternative Russian designation is SAU-122, but in the Russian Army it is commonly known as Gvozdika. The 2S1 is fully amphibious with very little preparation, and once afloat is propelled by its tracks. A variety of track widths are available to allow the 2S1 to operate in snow or swamp conditions. It is NBC protected and has infrared night-vision capability.
The 2S1 was developed in Kharkiv, Ukrainian Soviet Socialist Republic. It has seven road wheels on each side; the running gear can be fitted with different widths of track to match terrain. The interior is separated into a driver's compartment on the left, an engine compartment on the right and a fighting compartment to the rear. Within the fighting compartment the commander sits on the left, the loader on the right and the gunner to the front. The all-welded turret is located above the fighting compartment. The 2S1 uses a 122 mm howitzer based on the towed D-30 howitzer. The gun is equipped with a power rammer, a double-baffle muzzle brake and a fume extractor. It is capable of firing HE (high explosive), leaflet, HE/RAP, armor-piercing HE, flechette and chemical rounds.
