Development of the KTO Rosomak

In 2001, a competition was held to replace the cold war era 8x8 OT-64 Skot, a domestic APC also produced and used by Hungary, ans the local version of the BMP-1 called BWP-1. An international competition was held in Poland to compare vehicles from various manufacturers. In the end, the Patria APW was seen in close compeition with the MOWAG Piranha P and Steyr Pandur. The first won the contest and the Polish Ministry of National Defense in December 2002 choose to acquire a manufacturing licence from Patria for them to be built in Poland, some 690 Patria AMV were ordered at first.

About the Patria AMV

The Patria was a Finnish vehicle which studies went back to the post-soviet era, with work starting in 1995 but in service by 2007. This very modular 8x8 APC was inspired by the 1970s Swiss Mowag Piranha and declined into a main variant in 2013 called AMV featuring a heavily versatile compartment designed for easy and cheap conversions to numerous variants. It was widely exported, eight countries purchasing it. It was also evaluated by Australia and the US (Havoc). It is also domestically built as the South African Badger, and the Slovenian SKOV Svarun.

They are also internally designated XC-360P with last Deliveries by 2019 by adding a total order of 997 plus a remainder of Finnish-built Patria vehicles. The Polish Army ordered 690 vehicles divided between 313 featuring the Oto Melara 30 mm Hitfist-30P turret, and 377 in other variants to be completed between 2004 and 2013.

The KTO Rosomak is a relatively massive vehicle, but still light at 22 tonnes (to compare with the Badger or Swiss Piranha V or 33 tonnes). It was closely modelled after the Patria with few changes, 7.7 m (25 ft) long overall for a width of 2.8 m (9 ft 2 in), an eight of 2.3 m (7 ft 7 in) and carrying a crew of three, the commander, driver, and gunner, plus eight equipped infantrymen in the aft section. In the basic turret version (IFV), the driver is on the right, engine on the left. The driver's hatch was rectangular, with a foldable glass block allowing him to be protected from the elements while having a much better visibility than classic persicopes. There is a second "war operation" low silhouette armoured glass above that can be setup instead, giving the driver still good vision while presenting a lower surface. Behind the driver was located the Commander and gunner, both in the turret. In that case, the commander is given a round hatch, opening forward for protection, and a single IR vision block forward, while the hatch cupola has a 360° traverse. He also shares in the turret a vision episcope. His hatch is semi-rectangular and he sist right behind the driver in other versions, notably the basic turretless APC.

The DI 12 Scania Diesel is located in the right compartment, capable of delivering an output of 360 kW (480 hp) or 405 kW (543 hp) deopending on the version for a power/weight ratio of 15.6 kW/t (21.2 PS/t). Its maximum speed was over 100 km/h (60 mph) with a limited, on flat, about 60-80 off-road and up to 10 km/h when swimming. In that case, preparations are limited to erect the trim vane, and lower the propellers.

As a 8×8 wheeled vehicle, each pair is independent, with central inflation system and suspended on torsion bars. The vehicle normal Operational range is about 800 km or 500 mi.

Production & Variants

Ten KTO Rosomak has been declined into ten versions, filling all the niche uses of the Polish Army: Infantry transport, Infantry combat support, command, ambulance, engineering, antitank, mortar and recce that fits nicely into Polish motorized infantry organically, and presents huge maintenance cost-savings.

Users includes Poland with 863 vehicles and the UAE with forty Polish-built AMW Patria. The Rosomak has been deployed for the moment to the War in Afghanistan, called the Polish task force, a contingent part of the International Security Assistance Force. It operated over 100 vehicles, including 5 medevac versions, with the M3 APCs equipped with additional armor. In 2008 one Rosomak was attacked by the Taliban and thanks to its add-on armour it survived a frontal hit by a RPG-7 rocket, and fired back, the returned to base safely. In 2009 however, the gunner was killed while travelling in a Rosomak M3 after an IED explosion. The vehicle rolled over and crushed the gunner standing in his open turret. The Rosomak was also part of the European Union mission in Chad (2007–2008), the EU Force Chad/CAR.
