(Washington, D.C.) The Russian Navy is reporting progress with its second 955A Borei-class nuclear armed ballistic missile submarine, an upgraded boat reported by Russian media outlet to incorporate some of the most advanced “quieting” technologies to ever exist.
Just last year, Russia deployed its first in series of at least seven upgraded Borei-A nuclear-armed ballistic missile submarines, called the 955As.
The second one, called the Knyaz Oleg, is slated to enter service in July of this year, TASS reports.
At least five more are on the way as well, according to TASS, which reports that three additional 955As are under construction and two more have been ordered.
The first of the Borei class, the 955s, were fielded as far back as 2013, however the 955As are reported to incorporate a number of technical upgrades intended to lower the submarine’s acoustic signature.
While details of these kinds of innovations are likely not available for obvious reasons, several reports point to the nature of the new quieting technologies incorporated in the 955A design.
An interesting 2017 analysis written in navyrecognition.com highlights a few of the innovations informing Russian efforts to upgrade the 955 submarines to the 955As.
