Dubbed the “Sledgehammer,” the self-propelled 2S4 Tyulpan mortar, known as the Tulip in English, has a 240mm cannon — twice the caliber of NATO mortars, which are just 120mm — making it by far the largest caliber mortar system in the world. Carried on its own tracks, it has a range of 19 kilometers and is used to destroy large fortifications, military equipment, or strategic positions. https://twitter.com/i/status/1609830576982298625

Out of hundreds produced, Russia is believed to have only 40 to 50 still in operational service. However, Moscow is believed to have 400 units in storage and to be activating additional mortars to send to the battlefield in Ukraine.
