These are 4 World’s Most Advanced and Dangerous Submarines based on its weapons load
The ranks refers to list of "H.I. Sutton at Covert Shores"
which have calculated it based on total number of torpedo tubes
assuming that they can be used to carry a torpedo
plus the maximum number of torpedo racks in the torpedo room
plus any VLS or slanted launch tubes
The Seawolf class, is a class of nuclear-powered fast attack submarines (SSN)
in service with the United States Navy
The class was the intended successor to the Los Angeles class, and design work began in 1983
A fleet of 29 submarines was to be built over a ten-year period
but that was reduced to 12 submarines
The end of the Cold War and budget constraints
led to the cancellation of any further additions to the fleet in 1995
leaving the Seawolf class limited to just three boats
Seawolf submarines are larger, faster
and significantly quieter than previous Los Angeles-class submarines
they also carry more weapons and have twice as many torpedo tubes
The submarines are able to carry up to 50 UGM-109 Tomahawk cruise missiles
for attacking land and sea surface targets
The submarines also have extensive equipment to allow shallow water operations
The class uses the more advanced ARCI Modified AN/BSY-2 combat system
which includes a larger spherical sonar array, a wide aperture array (WAA)
and a new towed-array sonar
Each boat is powered by a single S6W nuclear reactor
delivering 45,000 hp to a low-noise pump-jet
SSGN Oscar-II class cruise-missile submarines
are designed primarily to attack NATO aircraft carrier battle groups
In the late 1990s
Russia completed several new submarines of the third generation Oscar-II
11 of the larger Oscar-II submarines were built between 1985 and 1999 at the Sevmash yard in Severodvinsk
Three have been decommissioned and one, the Kursk, sank
Two Oscar-II submarines are active with the Northern Fleet and five with the Pacific Fleet
Oscar-II is about 33 ft longer than its predecessor
approximately 505 ft rather than 469 ft
providing space and buoyancy for improved electronics and quieter propulsion
The submarine is equipped with 24 SS-N-19 Granit or “Shipwreck” cruise missiles with a range of 342 miles
The missile has a length of 34ft and weighs 15,212 lb with a warhead weighing 2,205 lb
Its speed is Mach 1.5
The Pacific Fleet is set to upgrade four Oscar-II submarines
with 3M-54 Kalibr family of cruise missiles by 2021 as part of a multi-year programme
The submarines can also be fitted with other cruise missiles
including 3M-54 anti-ship
3M-14 land-attack missiles, and PT91 anti-submarine warfare (ASW) torpedoes
Severodvinsk-II class, also known as Project 885M Yasen-M
are a series of the newest nuclear-powered cruise missile submarines
designed by the Malakhit Marine Engineering Bureau and built by Sevmash for the Russian Navy
It is the first Russian submarine class to be equipped with a spherical sonar
designated as MGK-600 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
The Severodvinsk-II class nuclear submarines
are presumed to be armed with land-attack cruise missiles, anti-ship missiles
anti-submarine missiles including the P-800 Oniks SLCM
Kalibr family SLCM or 3M51 SLCM
Kalibr-PL has several variants including the 3M54K (terminal-supersonic)
and 3M54K1 (subsonic) anti-ship
91R1 anti-submarine, and the 3M14K land-attack variant
In the future, there will be also an option to install
the hypersonic 3M22 Zircon cruise missiles on upgraded 855M boats
Each submarine can carry 32 Kalibr or 24 Oniks
other sources claim 40 Kalibr and 32 Oniks
cruise missiles which are stored in eight (ten for 855M) vertical launchers
The Ohio class of nuclear-powered submarines
includes the United States Navy's 14 ballistic missile submarines (SSBNs)
and its four cruise missile submarines (SSGNs)
Each displacing 18,750 tons submerged
the Ohio-class are the largest submarines ever built for the U.S. Navy
They are the world's third-largest submarines
behind the Russian Navy's Soviet-designed 48,000-ton Typhoon class
and 24,000-ton Borei class
However, the Ohios carry more missiles than either
The Ohio Class submarine is equipped with the Trident strategic ballistic missile
Each SSBN submarine is armed with up to 24
Trident II submarine-launched ballistic missiles (SLBM)
Each SSGN is capable of carrying 154 Tomahawk cruise missiles
plus a complement of Harpoon missiles to be fired through their torpedo tubes
The Ohio Class submarine is also fitted with four
533mm torpedo tubes with an mk118 digital torpedo fire control system
The torpedoes are the Gould mk48
The mk48 is a heavyweight torpedo with a warhead of 639 lb
which has been operational in the US Navy since 1972
The torpedo can be operated with or without wire guidance
and the system has active and or passive acoustic homing
