The artillery of a very large caliber, as self-propelled 2S7 Pion or M110 or 2S4 Tulipan mortars, is now a dying species. This is due, among others, to the increasingly better achievements of the Kal construction. 152/155 mm, deficiencies in spare parts and increasingly melting stores of this caliber on a global scale. most likely 1 of the coffin nails for her will be the war in Ukraine, especially for the Pion, small Man and Tulips. However, in 1 country it was decided that it was worth freshening this artillery section and developing something new.
