Russia Claims Underwater Sonar System Of Its Borei-Class Subs Outpaces American Counterparts

Significant progress has been achieved in the intensified conflict between the West, led by the United States, and Russia concerning the Russian Avangard hypersonic glide vehicle and Borei-class subs. These developments pose potential challenges to the US and its allies.

Russia’s “Borei-class” strategic nuclear submarines are outfitted with cutting-edge underwater sonar technology that, according to Russia’s media, Ria Novosti, outperforms American counterparts by a factor of 1.5.

According to the source, Borei-class submarines have a significant edge in detecting enemy vessels, citing a Russian defence magazine.


The Irtysh-Amphora-B-055 hydroacoustics system outperforms the capabilities of the United States’ superior fourth-generation multipurpose nuclear submarines, such as the Virginia and Ohio-class SSBNs.

In an interview with Russia’s media, Victor Murakhovsky, the Editor-in-Chief, revealed that the Borei sonar technology could detect objects within a range of around 100 kilometres of US nuclear strategic submarines.

The Irtysh-Amphora-B-055 system aboard Borei submarines is multipurpose, enabling simultaneous tracking of at least 30 undersea targets.

This complex system, which includes an “Amphora” primary hydroacoustic antenna, side antennas, and a towed antenna, uses digital processing of signals for noise direction discovering, echo direction finding, and target classification.

Six submarines

This technology is useful in Arctic operations by measuring ice thickness, designating polynyas for surfacing or missile discharges, and detecting hostile submarines, torpedoes, and minefields.

The Russian Navy currently employs six submarines from Project 955 and Project 955A, comprising Project 955’s Yuriy Dolgorukiy, Vladimir Monomakh, and Alexander Nevsky, as well as Project 955A’s Knyaz Oleg, Knyaz Vladimir, and Generalissimus Suvorov.

Sevmash is constructing three more 955A ships: Dmitriy Donskoy, Knyaz Pozharsky, and Prince Potemkin.

In addition, Russia’s newly built nuclear-powered submarine, Imperator Alexander III, was revealed in December 2022 and is being tested. It will be part of the Pacific Fleet by the end of 2024, representing a significant boost to Russia’s naval capabilities.
