The Soviet B-4 203mm heavy howitzer are specialized in blasting enemy heavy fortifications or urban areas. Very heavy, it was best used as fixed or siege artillery that provided fire support at very long range. Its high-angled 100 kg shells can easily blast any building or grouping of light troops, even unidentified, in just a few shots. However the 203mm is imprecise at long range, and extremely slow, despite the fact it is self-propelled for local maneuvering thanks to an engine in that tracked chassis.

By itself, a single Gaubitsa unit is practically worthless, hitting wide of the mark, and taking quite a while to reload between shots. It's too inaccurate to do much damage despite its strength; however grouped together in units of 4+, and with the right target, Gaubitsas can destroy entire enemy bases, totally crippling and destroying war efforts in one well aimed volley.

On December the 11th, 1926 at a meeting, Artkoma made a decision: "To instruct C. B. Artkoma to develop project 203-mm howitzer great distance in 46 month" Letter № 51225/12YA5 on March 22, 1927 A. K. ordered C. B. "Artkoma" to make common projects 122 - mm gun cabinet, 203-mm howitzers ARGK and 152-mm guns ARGK. The howitzers project was completed on the 16th January, 1928 in two versions: with and without muzzle braker. Body of guns and ballistics in both versions were identical.
