• 2S1 modernized - The modernization is being carried out on the basis of the 122 mm towed howitzer of the Serbian modernization program. Project "SORA 122mm" and NORA B-52. Where the truck platform was abandoned, which was used by the prototype version of the "SORA 122mm" system in favor of a much better, crawler platform 2S1 Gvozdika system. The action was made possible by two new projectiles and an increased range of about 40% from 15,200 to. A new ballistic computer and fire control system make it much faster to prepare for action. There is also a new inertial navigation system, GPRS, as well as the possibility of action, multiple projectiles in one point, MRSI. Thus, it was achieved that with one 2S1 Gvozdika system, in the system of MRSI action in one point, 6 projectiles can be fired in one minute; the modernized 2S1 Gvozdika is much improved. For better defense, a turret with a 12.7 mm machine gun was added. In 2021, the first modernized 2S1 Gvozdika system battery was introduced in service with the Serbian Army.
