   The Wilk (wolf) is a new Polish fire support vehicle. It is based on a Rosomak, a Polish Army license produced version of the Patria AMV armored personnel carrier. The Wilk is fitted with a CT-CV 105HP turret. It has significant direct fire capability. Due to its weight the Wilk fire support vehicle is more strategically and tactically mobile comparing with main battle tanks.

   Recently Poland developed a whole host of combat vehicles, based on their Rosomak. The Wilk fire support vehicle is one of them. It seems that Poland fields rapid deployment brigades with Rosomak 8x8 heavily armored APCs in the same manner as US Army fields Stryker Brigade Combat Teams. Each rapid deployment brigade has 8x8 armored vehicles of various variants. Operational concept behind these brigades is stressed on speed, deployability and maneuverability to counter enemy forces. The Wilk will give the Rosomak equipped brigades the needed fire support.

   However it is unknown if the Wilk will enter service with the Polish Army. Or if the Polish MoD has a requirement for a wheeled fire support vehicle at all.

   The main role of the Wilk is to support infantry. It is effective against armored and soft skin vehicles, buildings and fortifications. Also it has secondary anti-tank capability. However this artillery system might not be very effective against modern main battle tanks. Unless attacking from ambush.

   The Wilk is fitted with a CT-CV 105HP two-man turret. This turret is designed for wheeled and tracked vehicles with a weight of 18 to 30 t. It is worth noting that the same CT-CV 105HP turret was also fitted on one of the versions of the Anders light tank. It is armed with a fully-stabilized 105-mm low-recoil gun. A 105-mm turret was selected, because 90-mm guns do not have adequate firepower, while 120-mm guns may be too heavy for this wheeled 8x8 APC.

   The Wilk fire support vehicle is compatible with all standard NATO 105-mm ammunition. It is also compatible with smart ammunition and can fire Falarick 105 anti-tank guided missiles. The Falarick missile is of Ukrainian origin. It is used to engage heavily-armored vehicles at long ranges. This missile has a semi-automatic laser guidance with tandem warhead. The Falarick 105 penetrates no less than 550 mm behind explosive reactive armor. There is an automatic ammunition loading system. Ammunition is stored in a separate compartment. Maximum range of fire is 4 km with ordinary rounds and 5 km with Falarick anti-tank guided missiles. Maximum rate of fire is 8 rounds per minute. The gun can be elevated to 42. This feature allows to adapt vehicle for urban and mountainous warfare. Also due to its elevation, this gun can fire in the same manner as howitzers. Indirect range of fire is up to 10 km.

   There is a coaxial 7.62-mm machine gun.

   The Wilk has advanced fire control system. It can fire both day and at night.

   This fire support vehicle is based on the Patria AMV, that is one of the most protected vehicles in its class. However it seems that chassis is better protected than the turret. Chassis of the Wilk has modular ballistic protection. Armor composes of interchangeable modules of various thickness and can be tailored to suit mission requirements. Heavy armor is removed during peacetime and for transportation. However it is restored once the vehicle arrives in the combat theater. Maximum protection level is against 30-mm armor-piercing rounds. Vehicle also has a top-class mine protection. It can withstand up to 10 kg TNT blast. Two uparmored Polish Army vehicles were hit in Afghanistan by RPG-7 rockets, however armor was not penetrated and vehicles managed to return to base. The Wilk is also fitted with NBC protection and automatic fire suppression systems.

   This fire support vehicle is operated by a crew of three, including commander, gunner and driver.

   It seems that this fire support vehicle is powered by a Scania DI 12 turbocharged diesel engine, developing 540 hp. Vehicle is fitted with a central tyre inflation system. It seems that the Wilk lost its amphibious capability due to increased weight.

 

Variants
