General Characteristics
The 2S4 Tyulpan (Russian for “Tulip”) is a Soviet-era 240 mm self-propelled heavy mortar. It is the largest caliber mortar system currently in active use worldwide. Developed in the early 1970s, the 2S4 was designed to destroy hardened defensive positions, fortified strongpoints, command centers, and targets on the reverse slopes of hills—objectives that are difficult for conventional, low-angle artillery to strike. The massive 240 mm mortar is externally mounted at the rear of the hull and is hydraulically lowered onto a baseplate on the ground for firing. This system is known for its ability to fire conventional high-explosive, laser-guided, and historically, tactical nuclear munitions.
