Developed during the cold war the 2S4 Tyulpan 240mm system entered service in 1972. However the vehicle was not officially seen in the west until the mid 1970s where it was designated M-1975 by NATO. 

The mortar itself is somewhat unusual in that rounds are loaded from the breech rather than the muzzle as on smaller mortars such as the 81mm and 82mm mortars. 
The vehicle can carry up to 40 mortar rounds or 20 rocket assisted rounds. Regular rounds have a range of approximately 9.5km while the RAP rounds can push out around 20km.
However, due to the size of the 130kg projectiles the sustained rate of fire is only about 1 per minute.
