Description
The vessel's design is claimed to be state-of-the-art. The Yasen-class nuclear submarine is presumed to be armed with cruise missiles, with several types suggested, but not limited to the 3M51 Alfa SLCM, the P-800 Oniks SLCM or the RK-55 Granat SLCM. It will also have 8x650 mm and 2x533 mm tubes as well as mines and anti-ship missiles such as the RPK-7.
The hull is constructed from low-magnetic steel and is divided into nine watertight compartments. The class allegedly has a partial double hull, the forward part (compartments 1-4) being of a single hull design and the aft part (compartments 5-9) being a double hull design.
This class is the first Russian submarine to be equipped with a spherical sonar, designated as Irtysh-Amfora. The device (allegedly the Irtysh/Amfora sonar system) was tested on a modified Yankee class submarine. The sonar system consists of a spherical bow array, flank arrays and a towed array. Due to the large size of this spherical array, the torpedo tubes are slanted. However, some sources are not convinced that the device was indeed installed on the first-of-class. The submarine has a crew of about 90, suggesting a moderate degree of automation in the submarine's different systems. The newest U.S. attack sub, the Virginia-class submarine, has a crew of 134 in comparison.
Yasen-class submarines will be the first Russian SSNs/SSGNs equipped with a fourth generation nuclear reactor. The reactor will allegedly have a 25-30 year core life and will not have to be refueled.
A VSK rescue pod is carried in the sail.

Famous quotes containing the word description:
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
“A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.”
—John Locke (1632–1704)
