Armaments, self-protection, engines and mobility of the KTO RYS family of 8×8 wheeled armoured personnel carriers
The RYS basic version can be armed with different types of weapon systems according to the mission requirements.
The vehicle is equipped with external ceramic armour and internal anti blast cover LIM3. The armour provides ballistic protection for crew against small arms fire and 12.7mm calibre artillery shells.
The vehicle can be hinged with an up-armoured kit to provide level IV protection to STANAG 4569 standards.
The RYS family of vehicles are powered by EURO 3 compliant Iveco Cursor 8 259kW water-cooled diesel engine coupled to a semi-automatic gear box.
The power pack integrated in a rapidly changeable drive unit can be replaced within 20 minutes. The vehicle has low noise level (73 – 87 dBA), thus providing better work conditions in comparison with similar vehicles of this type.
The vehicle can be switched to amphibious mode without any special preparation before entering in to the water.
The maximum on-road speed of the vehicle is 100km/h and its amphibious speed is 10km/h. The central tyre inflation system fitted on the vehicle controls the air pressure on all tyres to provide better performance on different surfaces.
The RYS WAPC is transported by railway and low loading trailers.
The vehicle can be airportable by the C-130 Hercules transport aircraft.
