Abstract: A system for underwater vehicles for detecting and countering laser threats includes laser detectors and associated equipment to be placed in an underwater vehicle for providing protection of underwater vehicles. Detectors for detecting lasers are arranged on the surface of the underwater vehicle and controlled by a laser warning receiver and a signal processor. The risk of detection of the underwater submarine by laser radiation is reduced as a result thereof. Equipment for detecting and diverting objects are also arranged on the surface of the vehicle. The equipment for detecting and diverting objects are connected together and controlled by a laser control processor. The laser control processor directly communicates with a system for guiding weapons and with the laser warning receiver and signal processor.
