Super-Heavy Mortar Carrier
The 2S4 was built to put a 240 mm siege mortar on a mobile tracked chassis.
The 2S4 Tyulpan carried forward Soviet interest in very heavy mortars for destroying fortified positions and urban strongpoints. Instead of keeping the 240 mm M-240 as a purely towed weapon, designers placed a related mortar system on a tracked chassis. This gave Soviet forces a specialized weapon for targets too hard or sheltered for ordinary field artillery.
