Submarine for the high-latitude Arctic will be stealthier
Strategic nuclear submarine Arktur, for operation in the Arctic, will be more defficult to detect. This effect will be achieved by the faceted shape of its hull and its shaftless power plant.
"Arcturus’ new faceted shape together with its reduced size and the prospective active coating, reduces reflected sonar signals and decreases the detection range of the boat. The use of a distributed shaftless power plant, with full electric propulsion, helps reduce noise, and the availability of two propulsion systems increases the maneuverability and reliability of the missile carrier," said a representative of the Rubin design bureau at the Army-2022 exhibition.
He stressed that stealth will remain the main feature of submarine cruisers, but methods of detecting submarines are constantly developing, which means that ways to ensure stealth also need to change. Reduced noise pollution is leading to active low-frequency systems playing an increasing role in detection.
"These solutions are also important in terms of Arcturus' most promising application area – the high-latitude Arctic. Interest in this area will only grow in the coming decades. The faceted contours makes it easier to break up ice when surfacing and prevents the ice from lingering on the shaft lids, and better controllability is important for taking a position in the ice clearings," the speaker noted at the end of the report.
