The Sierra II is a nuclear powered SSN (fast attack submarine), designed to hunt other subs, and surface ships. Their crew is only 61 or so, and they
commissioned in 1990, and 1993. There are only two of the Sierra II class in service, the third was never finished. She is 111 meters long, with a
7600 ton surface displacement, and a 9100 ton displacement submerged.
The Akula class (earlier "incidents") is an SSN as well. Her crew is 73. The Akula I first sailed in the 1980s, and seven were built between 1986
and 1992. The Akula I and Improved Akula I are 110 meters long, and displace 8140 tons on the surface, and 12770 tons submerged.
The Akula II and Akula III is an improved version of the Akula I. Her crew is smaller, at 62 (half officers). The Akula II first entered service in
1995. Three were built between 1992 and 1995. There is one Akula III (which isn't an official NATO class) They are 113 meters long, and displace
8450-8470 tons on the surface, and 13400-13800 tons submerged.
One of the reasons that I say that the Russian Navy is so far behind is money. They had plans to build at least 21 Akula class hulls. Of those, 15
were built, one has since been leased to India (after many delays, including a leak that killed 8 sailors in trials), three were converted to the new
Borei class SSBN during building, one was scrapped at 60% complete, and two were sold for scrap. Of the remaining ones, five have been removed from
service, one has been scrapped of those five.
To compare to American subs as far as size goes:
A Los Angeles class SSN is 109 meters with a crew of 129 (13 officers, 116 enlisted). She has a displacement of 6927 tons submerged. Of the 62 hulls
built, 20 have been retired. Of the remaining hulls, 23 are the 688-I or Improved 688 class. Still a Los Angeles, but with improvements to the hull,
and onboard equipment.
A Seawolf (only three, one of which is a Special Operations hull), is 107 meters long, with a crew of 140 (14 officers, 126 enlisted). She has a
surface displacement of 8600 tons, and a submerged displacement of 9138 tons. The class consists of Seawolf, Connecticut, and the Jimmy Carter, which
was converted to a special ops hull. The Carter is about 30 meters longer, because she has an extra section of hull for Spec Ops missions.
A Virginia (brand new class, with only a handful in service so far) is 115 meters, with a crew of 135 (15/120). She displaces 7900 tons. She is one
of the only boats in service to date to use a pulse jet propulsor, which significantly quiets her, as there is almost no risk of cavitation. There
are currently 9 boats in the class. The Block I boats, of Virginia, Texas, Hawaii, and North Carolina. The Block II boats of New Hampshire, New
Mexico, Missouri, California, and Mississippi. The Minnesota is the last of the Block II boats, and will commission in 2013.
