. The holding "Ruselectronics" (included in "rostec" ) has begun delivery in the interests of the Navy of Russia stations visual optical interference 5P-42 " owl ", blinding the enemy and causing them hallucinations, said Last news in the press service of the organization. The instrument is equipped with Frigates " Admiral Gorshkov ", transferred to the Navy in 2018, and " Admiral Kasatonov ", passing the factory inspection. In the cabin of ships installed two sets of the " Owl ". Such equipment will be determined for another two frigates of project 22350, the construction of which is already underway in the shipyard " Severnaya Verf ". Station " owl "developed by JSC" experimental plant "Integral" (part of "Roselektronika" ). It is designed to suppress at night and twilight time of visual-optical and optical-electronic channels of supervision and aiming of small arms and melee weapons, used against surface ships and boats of the Navy. Action stations is based on the modulation of the brightness of the light radiation. Low-frequency oscillations of radiation intensity through stimulating the optic nerves to cause temporary, reversible disorder of the organs of vision. "A test of the number of volunteers indicated that it is impossible to conduct aimed fire from small arms (AK, SVD, PKM) on the target, blanking station, when placing stations at ranges of up to 2 thousand meters from the positions of gunmen due to the fact that" not visible ". 20% noted hallucinogenic effect, described as " a spot of light floating before my eyes ", and 45% complained of dizziness, nausea, signs of disorientation in space, "- said in " Roselektronika ". the organization explained that the radiation in the visible and infrared spectra in combination with high frequency modulation of brightness allows for ranges of up to five thousand meters effectively suppress night vision devices, laser rangefinders, infrared guidance system anti-tank guided missiles. Project 22350 frigates have a displacement of 4, 5 thousand tons, a length of 135 meters and a width of fifty feet, speed to 29 knots, cruising range of up to 4, 5 thousand miles, autonomy-30 days. The crew - 180-210. Armed frigates will consist naval gun mount A-192 "Armat" caliber 130 mm, launchers for 16 anti-ship missiles "Onyx" or "Caliber-NCE" and SAM " Polyment-Redoubt ". <span style="color:darkgray
