Command, control, and targeting systems
The gunner can survey, acquire and track a target, aim and fire from inside the turret with a closed hatch, or in a head-out position. The gunner's station is equipped with a day and night periscope sight. The day periscope sight has a unity magnification window with a collimated aiming circle and an 8× magnification sight with a ballistic reticle. The night periscope sight has a unity magnification window and an image intensifier x7.5 magnification passive night elbow.
The main components of the observation system are:[1]
Doppler radar (optional; 48 km of max detection radius)
Electro-optical subsystems: CCD camera (effective distance up to 20 km), FLIR and laser distance measurer
The standard armoured protection is rated to withstand 7.62 mm armour-piercing rounds through a full 360 degrees, and 12.7 mm armour-piercing rounds over a 30-degree frontal arc.
Rafael has supplied a passive add-on ceramic armour kit for the Valuk, which provides 12.7 mm AP round protection over the full 360 degrees.
The crew door at the rear of the vehicle is equipped with a periscope sight. The crew is protected against anti-tank and anti-personnel mines and a full nuclear, biological and chemical warfare protection system is fitted. The crew compartment is fitted with an automatic fire detection and fire fighting system, with 3 fire sensors and three Halon 1301 gas containers.
A version of the Valuk has been built with a rear ramp with an emergency door instead of two doors. The vehicle can be equipped with a capstan type cable winch.
