M120 Rak

The Rak Mortar can be built on a variety of chassis. The tracked chassis version is based on the lightweight HSW tracked chassis (which was developed from the Opal APC), while the wheeled chassis is based on the Rosomak APC. In 2013, as part of the MSPO exhibition, the manufacturer presented the implementation of the mortar on the chassis of the German Marder infantry fighting vehicle. The fire set of the 120 mm self-propelled mortars, Rak, consists of eight cannons, used to throw mortar bombs at a distance. It can shoot accurately at distances from 8 to 12 km. In addition to standard bombs, it can fire shells with a HEAT warhead for armored targets like combat vehicles, smoke shells, and illumination ammunition. The time to transition from march to the combat position is 30 seconds maximum. The combat position can be left within 15 seconds of the last shot being fired. The complete Rak mortar system, apart from the latter, includes accompanying vehicles: artillery command vehicles (AWD), reconnaissance vehicles, technical and logistic support (ammunition) vehicles and armament repair vehicles (AWRU). The vehicle is equipped with a digital fire control system, including a thermal camera and a laser rangefinder, so it can work effectively during the day or night. The data may, inter alia, draw from the FlyEye unmanned aerial vehicle. The Rak mortar can fire remotely as an unmanned weapon, using commands and data transmitted electronically to the vehicle's computer. Initially, until the implementation of modern ammunition with a range of 10,000 m, Polish Rak mortars use old OF843B bombs for towed mortars, modernized with special fittings, with a weight of 16.02 kg and a range of 6,900 m, intended for training.
