The 2S1 Gvozdika (Russian: 2С1 «Гвоздика») is a Soviet self-propelled howitzer introduced in 1972 and in service in Russia and other countries as of 2023. It is based on the MT-LBu multi-purpose chassis, mounting a 122 mm 2A18 howitzer.
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. 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.
