The French Suffren new generation multi-purpose nuclear submarine (Barracuda project) is participating in exercises using torpedoes. This submarine is considered one of the most stealthy, but it can be detected by Russian submarines of the Yasen-M project, writes military expert Evgeny Damantsev.
The expert emphasized that Barracuda-class submarines have an ultra-low acoustic signature (40 - 45 dB) due to the use of pump-jet propulsors.
Advanced domestic sonars based on active-passive phased array antennas MGK-600 "Irtysh-Amphora-Yasen", installed on submarines of project 885M "Yasen-M", are capable of detecting Suffren at a speed of 3-5 knots at a distance of up to 50 km in favorable hydrological conditions and up to 10-15 km in difficult hydrological conditions.
Submarines of project 885 Yasen and 885M Yasen-M are a series of Russian multi-purpose nuclear submarines armed with cruise missiles. The lead cruiser of the project, Severodvinsk, joined the Northern Fleet in 2014.
