Russia modernises batch of 2S4 Tyulpan self-propelled “nuclear” mortars

Russia’s Uraltransmash company, a subsidiary of Uralvagonzavod, has showcased the 2S4 Tyulpan self-propelled mortar upgraded with the new onboard systems and communication complex.

The Urals Transport Engineering Plant (Uraltransmash) modernized a batch of unique self-propelled mortars, which for a long time were in reserve. According to the local media, the exact number of upgraded self-propelled mortars is kept secret, but it is noteworthy that the project has been started since in 2016.

2S4 Tyulpan self-propelled mortar is an effective and terrifying weapon that, over the past 10 years, has been practically absent from military units. These self-propelled units have now been reactivated.


The self-propelled 2S4 Tyulpan mortars, of a caliber surpassing Western counterparts, had been practically removed from service, with around 430 of these weapons remaining in Russia, kept in storage at military bases.

Due to the large size, it can fire high-explosive, incendiary, guided, cluster, neutron and nuclear warheads, some of which are capable of hitting targets at a distance of about 20 km.

It saw action during the conflicts in Afghanistan and Chechnya. Some source reported that Russian mortars were used in 2014 for a hit the Lugansk airfield in Ukraine. The extreme firepower per round compensates for the Tyulpan’s slow rate of fire.
