Russian 2S4 Tyulpan: Largest mortar system, no equivalent in Western militaries

Grinding battle of attrition in Ukraine, Putin banking on the 2S4 Tyulpan mega mortar. The largest-caliber mortar system in service, no counterpart in western militaries. Mortars belt out gigantic 288-pound F864 shells more akin in effect to air-dropped bombs. 2S4 can also fire the 276-pound Smel’chak shell, guided by a separate laser designator. 3B11 nuclear shells & 3O8 ‘Nerpa’ shells that can release a hail of cluster bomblets.
