The American National Interest magazine appreciated the Russian submarines of the Ash project and the stealth of these submarines, because of which the United States lost their mark in the past, EDNews.net reports citing BulgarianMilitary.com.

The magazine reminded the words of Rear Admiral of the American Navy Dave Johnson, who was so impressed by Severodvinsk, the lead ship of the project, that he ordered his model for his office, “so as not to forget what the Navy will have to deal with.”

One of the advantages of “Ash” submarines is stealth. So, in 2018, when the Russian submarine sailed in the Atlantic Ocean, the US military could not find it for several weeks. The whole thing, NI explains, is in a case made of low-magnetic steel, which significantly reduces the magnetic signature of the submarine.

“In peacetime, losing a Russian submarine is a headache. During a conflict, losing a track of a submarine is a mortal danger,” the author concluded.

Submarines of the Ash project are a series of fourth-generation domestic multi-purpose submarines. The lead ship of the project – the nuclear submarine Severodvinsk – entered the fleet in 2014.

This fall, the Kazan submarine, designed under the modernized Yasen-M project, is also expected to be adopted. As part of this series, the domestic fleet should also receive the submarines Novosibirsk, Krasnoyarsk, Arkhangelsk, Perm, Ulyanovsk and two more ships.
