An apparatus (20) for destroying a target underwater object (22) includes a targeting system (28) and a gun system (32). The targeting system (28) has a laser (52) which produces a laser beam (30), a laser ranging sensor (56) sensitive to reflections (54) of the laser beam (30) from an underwater object (90), and electronic circuitry that determines the position of the target underwater object (90) using an output signal of the laser ranging sensor (56). The gun system (32) includes a gimballed gun that fires a projectile and is pointed at the underwater object (90) by the targeting system (28). The targeting system (28) may be operated to track the projectile (34) in the water as well as the target object (90) to be destroyed, and to correct the aim of the gun according to the relative position of the target object (90) and the projectile (34).

La présente invention vise un appareil (20) conçu pour détruire une cible immergée (22). Cet appareil se compose d'un système de visée (28) et d'un système canon (32). Le système canon (28) est muni d'un dispositif au laser (52) qui génère un faisceau laser (30), d'un capteur de télémétrie à laser (56) sensible aux rayonnements réfléchis (54) par le faisceau laser (30) lorsqu'il atteint un objet immergé (90), et de circuits électroniques qui déterminent la position de l'objet immergé (90) à l'aide du signal de sortie du capteur de télémétrie à laser (56). Le système canon (32) se compose d'un canon à cardan qui tire un projectile et qui est pointé en direction de l'objet immergé (90) par le système de visée (28). Ce système de visée (28) peut être utilisé pour suivre le projectile (34) dans l'eau tout aussi bien que l'objet immergé (90) à détruire, et pour corriger le pointage du canon en fonction de la position relative de la cible (90) et du projectile (34).
