As reported by the Russian media, on the frigates of the Russian Navy "Admiral Gorshkov" and "Admiral Kasatonov" visual-optical jamming stations 5P-42 "Filin", developed by the holding "Ruselectronics" of the State Corporation "Rostec", were installed.
"Owl" is a non-lethal weapon. Its principle of operation is based on the effect of low-frequency fluctuations in the brightness of light radiation on the optic nerves, which leads to temporary visual impairment.
At night and in conditions of poor visibility, the system effectively disables visual-optical and optical-electronic observation devices and aiming systems for small arms and artillery weapons on enemy ships.
The action of the 5P-42 "Owl" was tested on military volunteers. According to their confessions, once in the zone of operation of the station, they could not conduct aimed fire at targets from AK, SVD and PKM. 20% of the participants experienced a hallucinogenic effect in the form of a spot of light floating in front of their eyes, and 45% experienced dizziness, nausea, and signs of spatial disorientation.
In the near future, the 5P-42 "Filin" will be installed on two more frigates under construction at the "Severnaya Verf" in St. Petersburg.
