The Rosomak-Rak 120mm Self-Propelled Mortar System can conduct indirect, semi-direct and direct fire against mechanised units, command posts, command-observation points and fortifications. The contract for the production of 64 Rak mortar systems and 32 command post vehicles was signed between the MoND Armament Inspectorate and the consortium of Huta Stalowa Wola and Rosomak in April 2016. Each Polish artillery company comprises eight Rak 120mm mortar vehicles, four command-post vehicles for company and platoon commanders, two artillery reconnaissance vehicles, and three artillery ammunition supply vehicles. The Polish Land Forces are anticipated to take delivery of two artillery company modules a year until 2020.

Huta Stalowa Wola (HSW) is developing, as a private venture, a turret mounted 120 mm breech loaded mortar system called Rak to meet the potential requirements of the Polish Army as well as export markets. The turret is of all-welded steel armour protection that provides protection from small arms fire and shell splinters. The system will be operated by a crew of four people. As the system is turret mounted it will be capable of carrying out direct and indirect fire missions with maximum range of the latter depending on the projectile/propellant combination. Maximum stated rate of fire is between 10 and 12 rounds a minute. It is understood that when being used in the indirect fire role it will have a minimum range of 500 m and a maximum range of 12,000 m when being used in the indirect fire role.

The turret and the hull are of all-welded steel armour which provides a protection against small arms firing 7.62mm caliber, 155mm artillery shell splinters and hand grenades, unexploded artillery fragmenting sub-munitions, and other small anti-personnel explosive devices detonated under the vehicle (Level 1 STANAG 4569).T he RAK 120mm 8×8 self-propelled mortar carrier is motorized with a Scania DI1249A03P turbocharged diesel engine coupled to an automatic gearbox ZF 7HP 902S Ecomat with 7 forward and one reverse gears. The 8×8 chassis is similar to the Rosomak armoured vehicle personnel carrier with hydro pneumatic suspension system. The vehicle can run at a maximum road speed of 80 km/h with a maximum cruising range of 500 km. The vehicles can negotiate gradients up to 60% and side slope of 35%, fording depth of 1.5m without preparation. It can cross a trench of 2.1m width and a vertical obstacle of 0.5m.
