a network. The Ariete has a "hunter-killer" capability in which the commander spots and designates targets for the gunner in a 360° field of vision around the vehicle without changing his position or having to open the turret hatch for visual identification of targets. The commander's sight also has a vertical traverse from –10° to +60° from the horizontal, which allows the tank to engage low-flying airborne threats—primarily helicopters. During night fighting, the commander and gunner both share the thermal sight which is able to resolve a 2.3×x2.3 m target from a distance of 1,500 m. Crew and tank protection The Ariete's armour is a steel and composite blend, the turret front shape is similar to the British Challenger 1 and the American M1 Abrams. The Ariete features two side-mounted, electronically fired GALIX 80mm grenade launchers. Each launcher consists of four 80 mm barrels which can be intermixed with either smoke or chaff grenades. The smoke grenades are capable of shrouding the tank from visual or thermal detection, while the chaff grenades disperse the tank's radar cross section. The tank is fully NBC protected. Powerplant and drivetrain The Ariete is powered by a 25.8-litre turbo-charged Fiat-Iveco MTCA 12-cylinder diesel engine in a Vee configuration rated at 937 kilowatts (1,250 hp) at 2,300 rpm, with a maximum torque of 4,615 N·m at 1,600 rpm driving through a ZF LSG3000 automatic transmission, with four forward gears and two reverse, allowing for a top cruising speed of 65 km/h and a 0–32 km/h acceleration in 6 seconds. The computer-controlled transmission allows it to climb grades rated up to 60%, and can ford waterways of up to 1.25 m on-the-fly. The entire engine and transmission assembly can be replaced in under 1 hour. The Ariete's independent suspension system consists of 14 torsion bars with suspension arms, 10 hydraulic shock absorbers (installed on roadwheels numbers 1, 2, 3, 6 and 7), and 14 friction dampers. History Further development During the first years of adoption, the Ariete MBT showed some deficiencies regarding the powerplant. While the original V12 1,250 hp FIAT-Iveco MTCA (Modular Turbo-Charged Aftercooler) was a coupling of two of the V6 engines used by several Italian Army vehicles such as the Centauro tank destroyer and the Dardo IFV, it produced less power than the most advanced contemporary western designs. The Ariete's engine had to run at a high RPM to perform well, thus reducing
