Polish Armament Group has presented a new self-propelled mortar – named Rak (Crayfish) – which is based on the Rosomak (Wolverine) APC.
Rak is, without any doubts, one of the highlights of this year's Kielce Defence Exhibition. It was also placed in the background for the time when speeches of the officials during the inauguration of the Polish Armament Group (Polska Grupa Zbrojeniowa) took place. And it is not an overstatement – Rak system is a combination of modular mobility, armored wheeled platform with wide combat capabilities offered by the 120 mm mortar.
The mortar's maximum range up to 15 km and easy operation thanks to the auto-loading system make this weapon quite convenient. The commander of the vehicle has an integrated communications, command and fire control system based on TOPAZ device at his disposal. The communications suite also provides connection to the C4I class command and fire control systems. Additional equipment includes a ballistic computer, TALIN 5000 Inertial Navigation System (plus GPS and hodometer) and tactical visualization system based on a digital map. The vehicle is operated by 2-3 crew-members.
It is assumed that the mortar will be ready to open fire from a running position in less than 30 seconds, and it is able to change its position in under 15 seconds. The turret system allows the mortar to fire the rounds in the elevation range of -3º to +80º. Rate of fire – 6-8 rounds per minute with optional burst-fire mode – minimum 3 shots per burst.
