Submarines float on the surface by using ballast tanks full of air there are valves at the top of the ballast tanks that are open when it’s time for the submarine to submerge. So how deep can a military submarine go today we’ll present you guys the top deepest diving submarines ready for battle operations in the world. This list is based on test depth which is the maximum depth at which a submarine is permitted to operate under normal peacetime circumstances. So without further delay, let’s get started.

Deepest Diving Submarines List With Diving Depth Meters
10. Triumphant class Submarine
At number 10 is the Triumphant class which is a ballistic missile submarine of the french navy. In french the submarine is called the next generation device launching nuclear submarine which provides the ocean-based component of France’s nuclear deterrence strike force. The submarine’s propulsion system is a nuclear turbo electric system based on a type pressure water reactor supplying megawatt. Submerged displacement of this class is tons and it has a test depth of more than 400 meters.

9. Borei class Submarine
Next ,We have the Borei class which is a nuclear-powered ballistic missile submarine constructed by self-mash for the Russian navy. It is a fourth generation nuclear missile submarine which is less detectable to sonar than its predecessors. Other advancements include a pump jet propulsion it is also powered by an ok 650 nuclear reactor and aeu steam turbine. It is the first in Russia to run on the pump jet propulsion system and this class has a test depth 430 meters.

8. Yasen class Submarine
At number eight comes the Yasen class also known as guarani class. This class is a nuclear-powered cruise missile submarines again designed by Malakit and being constructed by selfmash for the Russian navy. Based on the Akula class and alpha class designs the asean class is projected to replace Russian navy’s current soviet-era nuclear attack submarines. It is powered with ok 650 kpm pressurized water reactor turbines or 43000 shaft horsepower the asm class has a test depth of 450 meters .
Type : Nuclear cruise Missile submarine
Speed : 28 kn (52 km/hr)
Displacement: 13,800 tons (sm)
7. Akula class Submarine
The seven deepest diving operational submarine in the world is the Akula class. The akula class first deployed by the soviet navy in 1986.It is a nuclear-powered attack submarines . The main machinery consists of vm5 pressure water reactor rated at 190 megawatt with a gt38 turbine two auxiliary diesels rated at 750 horsepower provides emergency power. The propulsion system drives a seven-bladed fixed pitch propeller and the submarine is rated for a test depth 480 meters.
Type : Nuclear cruise Missile submarine
Speed : 35 kn (65 km/hr)
Displacement: 13,800 tons (sm)
6. Seawolf class Submarine
At number six Deepest Diving Submarines list ,we have Seawolf class submarine. The sea wolf class is the fast attack submarines which was capable to attack with nuclear-powered in the united states navy. This class was the intended successor to the los angeles class and the nuclear-powered sea wolf has a ge pwr sw reactor system two turbines rated 52000 horsepower a pump jet propulsor a single shaft and one secondary propulsion submerged motor. The seawolf class submarine is rated for a test depth of 490 meters.
Type : Nuclear cruise Missile submarine
Speed : 35 kn (65 km/hr)
Displacement: 13,800 tons (sm)
5. Type 209 Submarine
Up next at number 5 is the type 209 submarine which is a German diesel electric attack submarine. Due to lack of submarine operations in German navy,they exported five variants of the class to 13 countries with submarines between 1971 and 2008. Propulsion include diesel electric or diesels a single shaft with 6100 shaft horsepower and the test depth of this submarine is the same as the previous one that is 490 meters.
Type : Diesel electric attack submarine
Speed : 22.5 kn (42 km/hr)
Displacement: 1810 tons (sm)
4. Vanguard class Submarine
And now with number four we have the Vanguard class. The vanguard class currently serving with the royal navy.This is a nuclear-powered ballistic missile submarine. A new pressurized water reactor the rolls-royce pwr2 was designed for the vanguard class. The reactor drives two gec steam turbines linked to a single shaft pump jet propulsor giving the submarine a maximum submerged speed of over 25 knots. They are the largest submarines manufactured in the uk displacing 15900 tons when submerged. This submarine is rated for a test depth of 500 meters.
Type : Nuclear cruise Missile submarine
Speed : 25 kn (46 km/hr)
Displacement: 15,900 tons (sm)
3. Sierra class Submarine
Up next at number 3 is the sierra class which is a nuclear-powered attack submarine intended for the soviet navy and currently in service with the Russian navy. The particular submarine class is unique for its design. Its light weight and made with strong titanium pressure hull. This design enables the submarines to dive to more depths reduce the level of radiated noise and increase resistance to torpedo attacks. It is powered by a single ok pressurized water reactor and the sierra class has a test depth of about 520 meters.
Type : Nuclear powered missile attack submarine
Speed : 34 kn (63 km/hr)
Displacement: 8300 tons (sm)
2. Type 039A Submarine
At number two is the type 039A submarine also known as yuan class according to NATO. It is a class of diesel electric submarine developed for the Chinese people’s liberation army navy. It is china’s first air independent propulsion-powered submarine and presumed to be one of the quietest diesel electric submarine classes in service. According to u.s naval institute the yuan class was primarily designed as an anti-ship cruise missile platform.This submarine class capable of hiding submerged for long periods of time in difficult to access shallow littorals. It has a test depth of 550 meters.
Type : Diesel Electric Submarine
Speed : 20 kn (37 km/hr)
Displacement: 3600 tons (sm)
