Top 10 Attack Submarines

Which is the best attack submarine in the world? Which is the greatest and deadliest modern attack submarine and why? Our Top 10 analysis is based on the combined score of offensive weapons, stealthiness, and some other features.

The main mission for this type of boats is to engage enemy submarines and ships. It must have good sonar to detect enemy submarines. Also it is extremely important to approach enemy boats and warships undetected. And leave the area after engagement undetected by enemy anti-submarine ships and maritime patrol aircraft.Some of the latest attack submarines can launch cruise missiles against ships and inland targets.

This list only includes nuclear-powered attack submarines, that are currently in service with around the world. We do not consider boats that are still being developed or are under construction.

Currently top 10 attack submarines in the world are these:

Nr.1Seawolf class(USA)

Entered service: 1997
Diving depth: 487 m
Torpedo tubes: 8x660-mm
Weapons: Mk.48 torpedoes, Sub-Harpoon anti-ship missiles and Tomahawk cruise missiles

The boats of the Seawolf class are the most advanced but also the most expensive hunter-killer submarines in the world. These submarines were intended to restore the technological edge which the US Navy had enjoyed over the Soviets from 1945 until the mid-1980s, when espionage and the cynical trading practices of some US allies somewhat eroded it.

The Seawolf class boats were intended to seek and destroy the latest Soviet ballistic missile submarines, such as the Typhoon class and attack submarines such as the Akula class.

Initially 12 boats of the class were planned. However these advanced submarines were too pricey even for the United States to build and maintain on the post-Cold War era budget. Eventually production was stopped with only three Seawolf class submarines built. All of these boats are currently in service. The US Navy switched to much cheaper design of Virginia class attack submarines.

The Seawolf class submarines are arguably the quietest submarines in the world ever constructed. It is exceptionally quiet even at high speeds.Most submarines need to keep their speed down to as little as 5 knots to avoid detection by passive sonar arrays, while the Seawolf class are credited with being able to cruise at 20 kots and still be impossible to locate. A Seawolf at 25 knots makes less noise than an older Los Angeles class submarine tied up alongside the pier.

These boats can operate at greater depths than existing US submarines and can also operate under the polar ice cap. Also these are faster than most other submarines.

These submarines have eight 660-mm torpedo tubes. These tubes are used to launched Mk.48 torpedoes and Sub Harpoon anti-ship missiles. Torpedo tubes are also used to launch Tomahawk land attack cruise missiles with a range of 1 700 km. A mix of 50 torpedoes, Sub Harpoons and Tomahawks can be carried.

Nr.2 Virginia class(USA)

Entered service: 2004
Diving depth: over 250 m
Vertical launched tubes: 12
Torpedo tubes: 4x533-mm
Weapons: Mk.48 torpedoes, Sub-Harpoon anti-ship missiles, Tomahawk cruise missiles.

The US Navy's Virginia class nuclear-powered attack submarine is as a successor to the Los Angeles class boats. It was designed as a smaller, cheaper and more versatile alternative to the advanced but extremely expensive Seawolf class. A total of 30 of Virginia class nuclear-powered attack submarines are planned.
The Virginia class submarines incorporate newly designed anechoic coating, isolated deck structures and new design of propulsor to achieve low acoustic signature. It is claimed that noise level of the Virginia is equal to that of the Seawolf class.
The Virginia class submarines are fitted with 12 vertical launch system (VLS) tubes. These are used to launched Tomahawk land attack cruise missiles with a range of 1 700 km. Also there are four 533-mm torpedo tubes. These are used to fire a total of 26 Mk.48 heavyweight torpedoes and Sub Harpoon anti-ship missiles.
These boats can be also used for special operations. It is the first US submarine to employ a built-in Navy SEAL staging area allowing a team of 9 men to enter and leave the submarine.

Nr.3 Astute class( United Kingdom)

Entered service: 2010
Diving depth: over 150 m
Torpedo tubes: 6x533-mm
Weapons: Spearfish torpedoes, Sub-Harpoon anti-ship missiles, Tomahawk cruise missiles.

The first Astute class nuclear-powered attack submarine was commissioned with the Royal Navy in 2010. So far 7 boats of the class are planned. These will replace the older Swiftsure class attack submarines.
The Astute class boats are significantly stealthier and carry more weapons than the previous boats of Trafalgar class.

These attack submarines are fitted with six 533-mm torpedo tubes. These are used to launch Spearfish torpedoes, Sub-Harpoon anti-ship missiles and Tomahawk cruise missiles. A mix of 36 missiles and torpedoes are carried.

The Tomahawk Block IV land attack cruise missiles have a range of 1 700 km and can target enemy ships as well as land targets.

Nr.4Graney class(Russia)

Entered service: 2013
Diving depth: ~ 300 m
Vertical launch tubes: 24
Torpedo tubes: 8x650-mm
Weapons: various torpedoes, anti-ship and cruise missiles.

The Project 885 Yasen (NATO designation Graney class) is the latest Russian nuclear-powered attack submarine. The lead boat, Severodvinsk, was laid down in 1993 however the project was stopped due to funding problems. It was commissioned with the Russian Navy only in 2013. The second boat of the class is built to improved project. Currently at least 6 of these boats are planned. These will become a successor to the older Akula class submarines.

Despite all improvements the Graney class boats are only slightly quieter than improved Akula class boats.
The Severodvinsk has 24 vertical launch tubes for various cruise missiles. Cruise missiles include the P-800 Oniks (SS-N-26), which has a range of about 300 km.
Also there are eight 650-mm torpedo tubes for torpedoes and anti-ship missiles. It is reported that a total of 30 torpedoes and anti-ship missiles are carried.

Nr.5 Sierra II class (Russia)

Entered service: 1992
Diving depth: ~ 400 m
Torpedo tubes: 4x650-mm, 4x533-mm
Weapons: Torpedoes, SS-N-15 Starfish or SS-N-16 Stallion anti-submarine missiles, SS-N-21 Samson cruise missiles
The Russian expensive Sierra Iand Sierra II class boats succeeded the ill-fated Alfa class.
These boats have two light and strong titanium hulls. These submarines can operate at great depths and provided reduced radiated noise levels as well as increased resistance to damage of torpedo attacks.
Soviet titanium technology was far in advance of the West, requiring fewer passes to achieve a successful weld, but the cost of the hulls limited the numbers built, despite advantages in depth and underwater speed.
The Russian Navy maintains these advanced submarines despite their high operating costs.

Nr.6 Improved Los Angeles class(USA)

Entered service: 1988
Diving depth: 450 m
Torpedo tubes: 4x533-mm
Weapons: Mk.48 torpedoes, Sub-Harpoon anti-ship missiles and Tomahawk land attack cruise missiles.
The US Navy currently operates a total of 40 older Los Angeles class submarines alongside the newerSeawolf and Virginia class boats. These submarines proved to be an exceptionally good ASW platform. First boat of the improved Los Angeles class was commissioned in 1988.
Improved submarines are much quieter. It is described that improved Los Angeles class boats are 7 times quieter than the original Los Angeles class boats.
The class features a very potent weapon array, including Mk.48 torpedoes, Sub-Harpoon anti-ship missiles and Tomahawk land attack cruise missiles. Tomahawk missiles can be launched from torpedo tubes of from dedicated vertical launching systems.
These boats can operate under ice where the Russian ballistic missile submarines tend to hide.
These boats can operate under ice where the Russian ballistic missile submarines tend to hide.

Nr.7Akula class(Russia)

Entered service: 1986
Diving depth: ~ 300 m
Torpedo tubes: 4x650-mm, 4x533-mm
Weapons: torpedoes and missiles
In the late 1980s Soviet Union launcheda number of Akula class boats.The Akula class marked a significant improvement in Soviet submarine design as it is far quieter than and earlier SSNs. Furthermore it was far quitter than Western countries expected. The use of commercially available Western technology to reduce noise levels played an important role in this eroding a long-held NATO advantage in the underwater Cold War.
Improved Akula II class boats became the first Russian submarines that were actually quieter than the latest US attack submarines of that time, the improved Los Angeles class boats. Sensors were also much improved comparing with the previous Soviet SSNs.
These attack boats have four 650-mm torpedo tubes and four 533-mm tubes. Up to 40 torpedoes and missiles can be carried.
Today Akula class boats make up about half of Russia's dwindling fleet of nuclear-powered attack submarines.

Nr.8 Soryu class (Japan)

Entered service: 2009
Diving depth: ~ 250 m
Torpedo tubes: 6x533-mm
Weapons: Type 89 torpedoes, Sub-Harpoon anti-ship missiles.
The first Soryu class boat was commissioned with the Japanese Maritime Self-Defense Forces in 2009. Unlike other nuclear-powered boats on this list the Soryu class submarines have diesel-electric propulsion. These attack submarines, fitted with air-independent propulsion system. Japan is the only country to use this class of boats.
Air-independent propulsion system allows to stay submerged for longer periods without surfacing to charge the batteries. Submerged endurance is increased from days to weeks. It also enhanced vessel's stealth and operational capabilities. However these submarines lack range and endurance of nuclear-powered attack submarines.
Soryu class submarines have hydrodynamic design and are fitted with anechoic coating. Interior also has sound isolation of loud components.
However these boats do not have vertical launch systems. Their armament is limited to Torpedoes and Sub-Harpoon anti-ship missiles.

Nr.9 Ohio class (USA)

Entered service: 2006
Diving depth: 300 m
Vertical launch tubes: 22 (154)
Torpedo tubes: 4x533-mm
Weapons: Mk.48 torpedoes, Tomahawk cruise missiles
The Ohio class submarines were originally designed to carry intercontinental ballistic missiles (SSBNs). However from 2002 to 2008 US Navy converted the four oldest submarines into cruise missile carriers (SSGNs). Conversion of the first boat was completed in 2006.
TheOhio,Michigan,FloridaandGeorgiawere converted to guided missile submarines by replacing Trident missiles with 7 smaller Tomahawk cruise missiles. Each converted SSGN is now capable of carrying 154 Tomahawk cruise missiles. Such amount of cruise missiles is typically deployed in a surface battle group.
Also there are four 533-mm tubes for Mk.48 torpedoes. Converted Ohio submarines also have lockout chambers and can transport special forces personnel.

Nr.10Oscar II class(Russia)

Entered service: 1986
Diving depth: 500 m
Missile tubes: 24
Torpedo tubes: 2x650-mm, 4x533-mm
Weapons: Various torpedoes and anti-ship missiles.P-700 Granit (SS-N-19 Shipwreck) cruise missiles.
The Project 949A Antey, known in NATO as the Oscar II classis a Soviet/Russian nuclear-powered cruise missile submarine (SSGN).These boats are the third largest submarines in terms of displacement and length. Only the Soviet Typhoon class and American Ohio class boats are larger. Also these are the largest attack submarines ever constructed. Currently these are among the most capable Russian submarines.
11 of these boats were built out of 19 planned. 4 boats remain in active service with the Russian Navy.
By modern standards these boats are far from being stealthy. However these submarines pack a formidable punch.Soviets designed these giant cruise missile boats to attack US aircraft carrier battle groups and coastal installations.
The Oscar II class SSGNs are armed with 24 P-700 Granit (NATO designation SS-N-19 Shipwreck) supersonic cruise missiles with a range of 550 km.
These submarines are also fitted with two 650-mm and four 533-mm torpedo tubes, capable of launching both torpedoes and anti-ship missiles. These include the SS-N-16 Stallion anti-ship missiles with a range of 50 km, carrying torpedoes, nuclear warheads or nuclear depth charges for use against surface ships or submarines.

I'm going with Virginia as number one, with a larger fleet they can effect a greater area.

Seawolf is damn good, but there are only three, and one isn't typically used as an attack sub, it's a special missions platform. This would be the 400ft USS Jimmy Carter, over 100ft longer than the other two Seawolfs.

A Norwegian says hello to SSN-22 USS Connecticut.

Often these Ohio class conversions aren't slinging missiles, they are transporting special forces.

They still have one hell of an attack though.

Same with Oscar II, any sailor would fear this beast. We may make fun of the Russians, like how they repainted the waterline on their old carriers to hide their list, or how they paint their ship's decks red to cover up rust, but we respect them like no other.

 

[Malik Alashter]

Extraordinary, no doubt these nations avoid each other since their clash is really a titan clash that will end in total destruction not only for them but to many nations follow them.

Look at the oskar class that Lol just a small island or the ohaio class.

 

[Stannis Baratheon]

Where is Yuan Class submarine!

ahahahhahaha..............the pic with the polar bear near the USS connecticut submarine made me laugh. LOL

Well , the seawolf class are still by far the best submarine ever built in the world. No other sub in the world even comes close to the sea wolf when it comes to stealthiness bar maybe our Astute class and improved Virginia class. Soi will still say the sea wolf beats any attack submarine in the world, not the Virginia. Since you just cant put the Virginia ahead because of numbers.If so some will argue North Korea with its dozens of mini subs is the worlds 3r largest naval power.lol I bet you 1 Seawolf can take on 3 Virginia's.

As for the Russians theydo make great nuclear sub, they have alot of experience buuilding such subs for decades, so igts no surprise they are among the top nucler sub builders in the world. When it comes to nuclear submarine tech building,patrol experience and world reach i respect them like no other as well(bar the U.S). @vostok you do make good subs. Respect.

Where is Yuan Class submarine!

It's good, but not quiet enough to be honest. Almost all of the subs i mentioned are more stealthy and have a proven track record of patrols worldwide, meanwhile the yuan has hardly ever indulge in global patrols for a considerable period of time. So it still needs more time to prove itself.

 

[FlyCheatter]

The best is Borei/Borei-||/Borei-A class ... period

Well according to a Russian patriot no doubt.

 

[vostok]

Well, of course, from my point of view, "Yasen" is best modern attack submarine, approximately equal to "Sea Wolf". But this is my opinion.

Same reply like the one above.

 

[Gabriel92]

The best is the Suffren. Period.

 

[vostok]

Same reply like the one above.

Well, neither we nor journalists do not have secret information and accurate data so that we are free to build any hypothesis. The best sub can only be chosen in the battle. But even then it is more likely to be a battle of captains and crews than steel.

 

[mike2000 is back]

ahahahhahahah............i swear i was waiting for you to turn up and say that. So says a French patriot.


However i agree that the Suffren alias Baraccuda class should be in the top 10 in the place of Japans Soryu(which is the only sub in the list i disagree with its position).
So will put the French Suffren alias Baraccuda class at number 8 instead of Soryu. However, in this classification we are talking about subs already in operation and with proven track records of Global patrols away from their neighbourhoods.i admit I will still put your triomphant class ahead of Japans Soryu though.

Sir,there has been an ongoing rumor that India will likely to ask for a new SSN to be custom built by Russia when our P.M. Mr.Modi's next month visit to Moscow apart from the 2 Akulas that India is all set to take lease from Russia.So,my question is whether there's a chance that Russia will custom build the new Yasen class for the Indian Navy??
