WARNING: PICTURE HEAVY!


The 90 mm-turreted armored fighting vehicle is a 6-wheel drive vehicle which uses most of the mechanical components from the VAB. It is equipped with the GIAT TS 90 turret armed with a new high-performance gun firing an anti-tank round with a high muzzle velocity.

 

Its high strategic and tactical mobility, its great autonomy, its discretion, its great ergonomics make it a particularly suitable vehicle to fulfill long-distance reconnaissance missions. Its powerful gun fires a hollow charge round with a muzzle velocity of 1000 m/s, making it suitable for anti-tank combat in all forms. It also features a N.B.C. protection.

 

The VBC 90 equips the Armored Group of the Gendarmerie Mobile in Satory.

FIRE CONTROL SYSTEMS

The fire control systems which can be adapted to the VBC 90 are as follows:

 

DAY FIRE

 

  • M 563 riflescope (GIAT) Magnification: 5.9 x Field: 190 thousandths

 

  • M 563 firing scope

SOPTAC 21 (SOPELEM): constituted by adaptation of a CI LAS TCV 107 laser rangefinder, providing the distance from the target. Manual reporting of this distance by the gunner.

SOPTAC 6 (SOPELEM): constituted by adaptation of a CI LAS TCV 107 laser rangefinder providing the distance to the target. The calculator automatically displays the increase in the reticle of the scope.

SOPTAC 13 (SOPELEM): constituted by adaptation of a CI LAS TCV 107 laser rangefinder providing the distance to the objective. The calculator automatically displays the increase in the reticle of the scope and provides the bearing tachymetry (target’s speed of movement) for shooting on mobile target.

 

DAY AND NIGHT FIRE

TJN2 90 rifle scope (SOPELEM) – Passive mixed rifle scope

day channel: 6 x magnification – 8° view

night channel: 5.5 x magnification – 8 ° view, range from 2000 m to 800 m (level 3 night: 10-3 lux)

 

  • Fire lines for TJN2 90 scope

SOPTAC 22 (SOPELEM): incorporated by adaptation of a CI LAS TCV 107 laser rangefinder providing the distance to the target. Manual reporting of this distance by the shooter.

SOPTAC 10 (SOPELEM): constituted by adaptation of a CI LAS TCV 107 laser rangefinder providing the distance from the target. The calculator displays the distance to the tank commander with automatic report of the increase in the reticle of the scope.

SOPTAC 11 (SOPELEM): constituted by adaptation of a CI LAS TCV 107 laser rangefinder providing the distance from the target. Calculator displays the distance to the tank commander with automatic report of the increase in the reticle of the scope, and provides the tachymeter bearing (target’s speed of movement) for shooting on mobile target.

 

  • CANASTA day and night fire control (THOMSON) constituted by adaptation of a passive TMV 562 night TV camera, a control box and one or two TMV 563 TV monitors. This system makes it possible to detect the target between 1000 and 2000 m, depending on the level of illumination at night, identify the objective, display the necessary shooting corrections by means of a mobile electronic reticle according to the shooting distance and the ammunition used, then point and fire with the shooting corrections.

 

  • Day and night fire control M 586 (GIAT) uses components of the COTAC anti-tank fire control. Constituted by a CI LAS TCV 107 laser rangefinder and by a computer integrating various data necessary for shooting on idle or mobile target: turret tilt, wind speed, outside temperature, speed and distance from the target.
