ABSTRACT:
This invention concerns a fire control system which is adaptable on a mantlet sight of a combat vehicle, and, in particular, is of the type that comprises a stabilized mirror 10, a rangefinder laser 13 and an electronic control unit.
The fire control system of the present invention includes a casing welded onto the turret mantlet, which contains a stabilized mirror inclined with respect to the horizontal line so as to correlate the stabilized aiming axis through the mirror to the gun trunnion axis and the firing axis, a laser being arranged so as to send and receive beams along the sight aiming axis of the mantlet sight and of the stabilized sight. Optical means are located between the stabilized mirror and the sight and are made up of a semi-transparent plate, a dichroic plate and a mirror to ensure the harmonization of the laser transmission and reception beams with respect to the aiming axis of the sight.
The dichroic plate is fixed and inclined at 45.degree. with respect to the aiming axis of the sight, and the mirror is located in a plane closely perpendicular to that of the dichroic plate, the plate and the mirror being capable reflecting the laser transmission and reception beams.
