the world's largest submarine ever built
the world's largest nuclear submarine can comfortably stay at sea for three months or more
it's powered by two pressurized water nuclear reactors and two steam turbines generating almost
275 000 horsepower driving the typhoon to a top speed of 27 knots 31 miles per hour in a world
of naval supremacy aircraft carriers may be the largest naval ships to sail the seas but arguably
a submarine the size of nearly two football fields is a little more intimidating the typhoon class
submarines of the russian navy are the largest submersible ships that have ever been built more
specifically the russian submarine known as dmitri donskoi tk208 is the world's largest submarine
how big is the submarine
measuring in at 175 meters nearly 600 feet submarine has been in commission since 1980 with
a few periods of significant refurbishment in its history in addition to the submarine's impressive
length it's also 25 meters wide giving it quite the presence in the water the displacement of
the ship is 48 000 tons and is operated with a crew of just 160 men these submarines are
capable of launching massive ballistic missiles from anywhere in the world relatively covertly
the ship is so big that the interior amenities are like no other submarine ever built
the ship's history
the ship was first launched in 1980 but in 1990 it entered an extensive dry dock period
to bring it up to modern standards it was there for over a decade until in 2002 the ship was fully
fitted with the latest hardware and relaunched into service the dmitri donskoi left drydock from
the russian city of severed events at this point and has been serving the russian navy ever since
it contains 20 launchers for the rsm-56 bulava ballistic missile this weapon system is known
around the world as one of the most advanced submarine-launched missile systems ever built
one interesting thing of note about the submarine is how extensively it was essentially rebuilt
during its dry dock period at first launch in 1980 it was referred to as a third generation
submarine but after spending over a decade getting refurbishments to its equipment
it's now referred to as a fourth generation submarine in its class
essentially the submarine was completely rebuilt with all new equipment
the world's largest submarine launched its first balava missile on september 27th
in order to do so the sub had to surface and the missile was fired from the white sea
by december of the same year the crew was ready to try the first firing of the bulava
missile from underwater notably the crews of the submarine fired many other tests
of the bulava missile including one failed test in 2009 and a successful one in 2010
the ship today
the dimitri danskoi is still in service today and serves as the pride of the russian submarine fleet
that said with the donskoi being the last of its class still in commission
its days are numbered the beret class submarines are replacing the typhoon class slowly these
new submarines are unfortunately smaller than the donskoi meaning that it's highly possible that the
world's largest submarine will hold that title for some time to come the new class of submarines has
been in construction since 2002 but the progress has been slow going so far there are four of the
new class of submarines in commission with another slated to be commissioned into service this year
ohio class submarine
the ohio class submarine is the fourth biggest in the world the u.s navy operates 18 ohio-class
nuclear-powered submarines which are the biggest submarines ever built for the u.s
each sub has a submerged displacement of 18 750 tons the first submarine of its class
uss ohio was built by the electric boat division of general dynamics corporation in groton
it was commissioned into service in november 1981. all the other submarines
were named after u.s states except uss henry m jackson which was named after a u.s senator
each ohio-class submarine has a length of 170 meters a 13-meter beam and a 10.8 meter drop
the gliding speed on the surface is 12 knots and underwater is
20 knots the submarine class includes one s8g pressurized water reactor two geared turbines
one auxiliary kilowatt diesel motor and one shaft with a seven bladed screw the submarine is capable
of carrying 24 trident missiles the armament also includes four 53 centimeter mark 48 torpedo tubes
akula class
the akula class is a nuclear-powered attack submarine with a submerged displacement of 13 800
tons it includes 10 submarines of which nine are in the russian navy service and one in the indian
navy service the first sub in the class akula was commissioned into the soviet navy in 1984.
the submarine features a double hole composed of an inner pressure hole and an outer light hole
it's 110 meters in length has a beam of 13.6 meters and drought of 9.7 meters
the surface speed of the sub is 10 knots while the submerged speed is 35 knots
the submerged endurance is a hundred days its main machinery includes one pressurized
water nuclear reactor one steam turbine and two turbo generators rated at two thousand kilowatts
the propulsion system includes one seven bladed propeller and one retractable electric propulsor
for reduced speed cruising the submarine can be armed with up to 12 submarine launch cruise
missiles capable of carrying nuclear warheads up to a range of 3 000 kilometers the armament
also includes four 533 millimeter torpedo tubes and four 650 millimeter torpedo tubes
sierra class
the sierra class with a submerged displacement of 10 400 tons ranks as the world's eighth biggest
submarine four sierra submarines are currently in service with the russian navy sierra 2 an
improved version of the class entered into service in 1990. these sierra class submarines are built
with light and strong titanium pressure hole which allows the submarine to reach greater
depths and reduces the level of radiated noise it also increases resistance to torpedo attacks the
submarine has a length of 111 meters and a beam of 14.2 meters the main equipment includes one
pressurized water nuclear reactor two emergency motors one shaft and two spinners the submerged
speed is 32 knots the assault equipment includes four 650 millimeter torpedo tubes four millimeter
torpedo tubes ss n21 samson slcm ssn 15 starfish anti-submarine weapon ssn 16 stallion and 42 mines
vanguard class
the vanguard class has a submerged displacement of 15 900 tons making it the sixth biggest submarine
in the world the nuclear-powered ballistic missile submarine is in service with the uk's royal navy
the class consists of four submarines namely vanguard victorious vigilant and vengeance
the submarines were built by vicar shipbuilding and engineering the first sub in the class hms
vanguard was commissioned in 1993. all the submarines are based at hm naval base clyde
which is located 40 kilometers west of glasgow in scotland the vanguard class
submarines are 149.9 meters long and have a beam of 12.8 meters and a drought of 12 meters
its main machinery includes one pressurized water reactor supplied by rolls-royce two 20.5 megawatt
turbines manufactured by gec two auxiliary retractable propulsion motors and one shaft pump
jet propulsor two turbo generators and two diesel alternators are also installed aboard thanks for
