122-mm SPG "Gvozdika"

Directions of modernization

• Replacements of out-of-date 122—mm gun 2A31 on modern rifled 120—mm 2A80, allowing to fire by the increased destructive power shells, by all kinds of 120—mm mortar rounds of the Soviet/Russian and foreign manufacture, 120—mm high precision guided shells. The modernized canon 2S1M, armed by semi-automatic rifled gun 2A80, is capable to deliver aimed direct and indirect fire without preliminary preparation of the fire position.
• Installation of the automated elevation and traverse laying control system;
• Installation of automatic survey and orientation system;
• Satellite signals reception and initial orientation equipment.

• After modernization the efficiency of SPG’s combat application grows not less than in 3 times for the account of:

• Increase of aimed firing rate from 4… 5 rds./min up to 7… 9 rds./min (fixed round, automatic realignment);
• Increase of ammunition destructive power up to 2 times;
• Decrease of minimum nonricocheting firing range from 4,04 km up to 1,5 km with HE FRAG projectiles and up to 0,42 with mortar rounds;
• Use of Kitolov—2 guided shells;
• Use of the rounds with Balansir shaped charge fragmentation bomblet projectiles with electronic time blasting fuse;
• Improvement of firing mode (barrel cooling, availability of barrel overheat indicator, elimination of gas pollution);
• Improvement of conditions for the crew;
• Reduction preparation time for the first shot;

• Ensuring of code telecommunication with future-oriented control facilities
