History
KTO Rosomak is the Polish version of the AMV vehicle developed by the Finnish company Patria Vehicles. Patria won the tender for 690 wheeled armored personnel carriers concluded in December 2002, defeating competing vehicles – the Pandur II and the Piranha IIIC.
The name “Rosomak” was chosen in a competition organized by the monthly “Nowa Technika Wojskowa”. The new transporters were to replace the withdrawn OT-64 SKOT vehicles and enable the withdrawal of some BWP-1
By decision of the Chief of the General Staff of the Polish Army on December 31, 2004, the carrier was accepted for service. The first Rosomak carriers, manufactured in 2004, were delivered to the army on January 8, 2005 (three in the combat version with the Hitfist-30P turret and six basic vehicles without armament). In addition, 82 Rosomaks were delivered to the army in 2005, including 42 basic chassis, and 39 in 2006 (just the basic chassis). Under the first contract, the army received a total of 570 vehicles, including 359 in the combat version.
The combat version of the APC is equipped with the two-man Hitfist-30P turret, developed by Italy’s OTO Melara. production of most of the ordered vehicles is to take place in Poland. The production line for the APCs was established at the Military Mechanical Works in Siemianowice Śląskie. The assembly line, and later the turret production, was transferred to the Bumar-Łabędy plant in Gliwice.
In May 2007, the first 24 Rosomaks equipped with the Hitfist turret were deployed to support the Polish Military Contingent in Afghanistan and entered combat operations in mid-June. This also marked the combat debut of the Rosomak. They were fitted with additional armor from late July 2007. During the first six months, they covered over 85,000 km and several were damaged, including two seriously by fougasse, but the crews suffered no serious injuries. Subsequent combat also resulted in relatively few crew losses, primarily to vehicles destroyed by high powered fougasses. As a result of the intense fighting, the number of Rosomaks in Afghanistan increased, reaching 89 in 2010, with the highest number reaching 134 (a total of 181 vehicles deployed).
According to unconfirmed estimates, almost every vehicle was hit at least once by small arms or anti-tank weapons, and more than half required repairs. They were most frequently attacked by RPG-7 anti-tank grenade launchers and large-caliber machine guns (12.7 mm and 14.5 mm). Despite this, irreversible losses on the ground amounted to eight Rosomaks M1M and six M3, and after damage assessments in Poland, a total of over 30 vehicles were written off. The additional armor fulfilled its function against the anti-tank weapons used in that conflict, and it is estimated that the use of the additional armored Rosomaks saved the health or lives of over one hundred soldiers.
The Ministry of National Defense signed a second contract for Rosomak vehicles on October 24, 2013. It covered the delivery of another 307 vehicles, this time all in their basic version. In 2018, 2019, and 2020, annexes were made to this second contract, reducing the total to 11 basic vehicles. Their production was transferred to new, separate contracts dated March 9, 2018, September 3, 2019, and December 21, 2020, concerning a specialized version of the Rosomak-WD command vehicle. Currently, contracts are being implemented for Rak 120mm self-propelled mortars, AWD artillery command vehicles, AWR artillery reconnaissance vehicles, Rosomak-WRT technical reconnaissance vehicles, and the integration of 70 ZSSW-30 turrets with Rosomak chassis.
Polonization
Initially, KTO Rosomak vehicles were equipped with Swedish Armox steel for their armor.
Starting in 2010, production shifted to using ARMSTAL steel manufactured by Huta Stalowa Wola (HSW).
The vehicle is also equipped with various systems, including the CHERDES NBC protection, the TALIN navigation system, Hertz Systems HGPST-T GPS receiver, and the FONET digital communication system. In 2022, the TILDE FC thermal imaging camera began to be phased out in favor of the polish KLW-1R Asteria thermal camera.
