The formal handover of the vehicles to the Polish Armed Forces by the consortium of the Polish Armaments Group (PGZ) and Huta Stalowa Wola (HSW) took place on Thursday, December 4, in Stalowa Wola, with the participation of Deputy Prime Minister and Minister of National Defense Władysław Kosiniak-Kamysz, Deputy Minister Paweł Bejda, and the head of the Armaments Agency, Maj. Gen. Artur Kuptel.
This marks the execution of the first implementation contract, signed on March 27, 2025, worth approximately 6.57 billion PLN gross, which covers deliveries of 111 vehicles between 2025 and 2029. The contract also includes, among other elements, training and logistics packages (First series-production Borsuks contracted).
The implementation contract resulted from the framework agreement dated February 28, 2023, which defined the rules and conditions for concluding subsequent executive contracts related to the delivery of Borsuk infantry fighting vehicles and the entire family of specialist tracked vehicles based on the Universal Modular Tracked Platform (UMPG) for the Polish Armed Forces (Framework agreement for nearly 1,400 Borsuk IFVs).
Under the framework agreement, approximately 1,400 vehicles will be procured throughout the duration of the program, including specialist variants such as Żuk reconnaissance carriers, Oset command vehicles, Gotem medical evacuation vehicles, Gekon maintenance and recovery vehicles, and Ares CBRN reconnaissance carriers.
On April 28, 2022, an additional four prototypes (on top of the initial prototype) were contracted to conduct system-environment testing. Since November of the same year, the first prototype has undergone tests at the Land Forces Training Center in Orzysz, supervised by its future first user, the 15th Mechanized Brigade.
The Borsuk IFV, based on the Universal Modular Tracked Platform (UMPG), is equipped with the 30 mm ZSSW-30 Remote-Controlled Turret System. The crew consists of three soldiers: the commander, the gun operator, and the driver. The vehicle is designed to transport six soldiers to the battlefield while providing adequate protection, and to support infantry units using its onboard weapons. With its weapons system, the vehicle can engage infantry, armored vehicles, aerial targets, and other adversary assets in all weather conditions and at any time of day. It features high mobility and can overcome terrain obstacles, including water obstacles by swimming, and can operate in various climatic conditions. The maximum road speed is 65 km/h, and its swimming speed is 8 km/h. The combat weight in the baseline configuration is 28 tons.
The ZSSW-30 remote-controlled turret is armed with a Bushmaster Mk.44S automatic cannon that enables both automatic and semi-automatic fire using five types of ammunition, including programmable rounds. The auxiliary armament integrated with the turret is a modified 7.62 mm UKM-2000C machine gun. Additional armament includes a twin launcher for anti-tank guided missiles.
The Borsuk infantry fighting vehicle has been under development since 2014, based on a contract signed on October 24, 2014, between the National Centre for Research and Development (NCBiR) and a consortium of Polish entities led by Huta Stalowa Wola. The consortium includes: OBRUM Research and Development Center, Rosomak, Military Electronic Works, Military Engineering Works of Dęblin (now part of HSW), Military Automotive Works, War Studies University, Military University of Technology, the Military Institute of Armored and Automotive Technology, and Warsaw University of Technology (MSPO 2025: HSW unveiled a model of the Ratel Heavy Infantry Fighting Vehicle).
