Sweden may be a small country that you
might second-guess when it comes to
military but for a country of peace and
prosperity believe it or not it's got a
lot of bite behind it and although some
may have some issues with the current
level of spending within the military
you have to admit that the technology
that Sweden has invested in has helped
Sweden great in the modern world and
with that today we look at one of the
most amazing and advanced submarines in
the entire world one that you would
raise your eyebrow over if I told you it
comes from the country of Sweden and
with that today we look at Sweden's
Gotland submarine and look at not only
how great it is but how it was capable
of eluding the entire American fleet for
over a year
how's it going everybody what's up my
name is Dave Wawa and welcome to FTD
facts the channel where I look at people
cultures and places from all around the
world and in this type of video we're
looking at military gear and I gotta say
guys I'm really excited to be talking
about the Gatlin submarine it is so
advanced it is so amazing I am
absolutely blown away that Sweden has
made something like this you know you
don't think of Sweden as this major
technologically advanced military
country Sweden alone does a lot of great
technological achievements but in terms
of military you're just like maybe so at
the beginning of this video I already
got a salute the Swedes and say you guys
are some smart son of a guns and before
I give in this video if you guys liked
learning about military content and you
want to learn more about stuff from
Sweden or just military gear in general
just hit that like button and don't
forget to leave a comment for a future
FTD facts video down there but let's get
started shall we
so the Gatlin submarine it might be a
diesel-electric submarine which many of
you guys to yourself might be saying oh
that's outdated that's old you know
that's pish-posh nuclear submarines are
better not necessarily because even
though it is not a nuclear submarine it
is considered one of the most advanced
submarines in today's worlds even by the
standards in 2019 and what makes this
submarine so fantastic is the fact that
this sub is extremely quiet you know you
can't hear it
impossible you have to have the best
gear and the best ears in the world to
hear this sub basically it was so deadly
that it managed to slip past American
forces and destroy the USS Ronald Reagan
in a war game by the way when this
happened with the Ronald Reagan what is
one of the newest aircraft carriers for
the entire American fleet and what I
mean that they blew up this aircraft
carrier I don't mean they actually blew
it up what they did was during the war
games they managed to get close enough
to take photos of the aircraft carrier
which in turn meant that they were
capable of firing a torpedo at it and
take it down so you might be wondering
to yourself how did this happen why is
this engine so quiet well with that we
got to go back to 1987 and 1988 during
that year the defense company known as
cockles Naval solutions which is owned
by the sub group which makes the sub
Griffon and all those great amazing
fighters for Sweden the company had
recently developed a new form of engine
for their submarines this was called the
Sterling air-independent propulsion
engine or simply known as AIP and in
November of 1937 they installed this new
type of engine on an older nacchan class
submarine known as the HS WM s snackin
as a matter of fact to get this new AIP
stirling engine the submarine itself had
to go into drydock and had to be
extended by eight feet basically they
cut that baby right in half split it and
then they added some more metal whatever
they put on submarines and shortly after
that this submarine left its drydock on
September 8 1988 and began years of
testing for this new engine so you might
be wondering yourself what is so good
about this engine why does it help this
submarine be so quiet one downside to
the diesel electric engines from the
past is they were extraordinarily loud
and they rattled and vibrated a lot and
you could hear that through the sonar
but for this particular engine it's
vibration amount is down to a very very
very small amount and it makes it really
hard to hear one other big drawback to
diesel electric engines is back in
day you couldn't stay underwater for a
long time compared to nuclear submarines
which yes still to this day have a much
longer range and can stay underwater for
a long time the new sterling AIP engines
allow the diesel electric submarines to
work continuously operating underwater
by burning liquid oxygen or diesel which
in turn allows the submarine to stay
underwater in operation from a few days
to simply a few weeks and that's another
thing when it comes to nuclear reactors
within nuclear submarines they can also
be quite loud but another major
advantage when it comes to the detection
of submarines is that the AIP engine and
the submarine itself is capable of
keeping its infrared signature very very
low and with the Gala's submarine
specifically these engines are designed
to drive the 75 kilowatt propulsion
system
as a matter of fact to give you an idea
how silent these engines actually are
one of the commanders of the HS WMS
Gotland named Eric linden says that this
submarine is capable of going into much
more shallow shores compared to nuclear
submarines which in turn says that there
is nowhere in the world that this
submarine could go undetected now let's
jump back to the nacchan because it took
only a couple of years for them to
figure out the test for this engine was
extremely successful because it was only
shortly after that the HS WMS Gotland
was commissioned on october 10th of 1992
and it was the first of three Gotland
class submarines that were commissioned
by sweden which all three were launched
in 1995 and commissioned in 1996 this
also made the HS WMS Gotland the first
ship to be made specifically for the AIP
system also with that let's look at some
of the specifics of the Gotland class
submarine as stated there is currently
three of them owned by Sweden this as
the Gotland the upland and the Holland
and as for the length of this class of
ship it comes in at 190 feet or sixty
point four meters the beam length is 20
feet four inches by six point two meters
and the draft is 18 feet four inches or
5.6 meters
as a matter of fact for this submarine
it actually has four different engines
it's got a lot the reason for that is
because two of them are the standard
diesel electric MTU engines and the
other two are the Cochran's v4 275 our
stirling AIP units basically let's make
some things very clear here when the
craft actually uses the diesel engine it
doesn't work quite as effectively when
it comes to its stealth whereas if you
really want to engage the stealth you
have to use the AIP engine and that's
why there are four engines now for the
speed of this craft they say surfaced
it's anywhere between 11 knots which is
approximately 20 kilometers per hour but
submerged of course submarines work much
better coming in at 20 knots which is 37
km/h interesting enough when the Gatlin
class submarine uses its AIP engines it
actually has to move much slower for it
to be extraordinarily effective and with
that they save for the AIP it's anywhere
between 5 to 11 knots within the ship
you also have a very small crew of 18 to
20 officers and approximately 6 to 10
seamen but one thing that's very
interesting about this submarine is that
the ship is controlled by one individual
for both depth and course compared to
other ships but for weapons interesting
enough although it is a small submarine
as a matter of fact it's got six torpedo
tubes four of these are the 533
millimeter or 21 inch torpedo tubes
whereas two of them are a little bit
smaller coming in at 400 millimetres or
15 point seven inch torpedo tubes on top
of that this ship can be armed with 48
times externally mounted naval mines and
four torpedoes these are actually quite
dangerous
Sweden loads up the Gotland submarine
with what is known as the torpedo mm
Sweden also calls these type of
torpedoes torpedo 62 which is made by
SAP befores underwater system and these
torpedoes are extremely fast it can
actually go up to 40 knots so good luck
trying to outmaneuver it for the range
believe it or not they can go as far as
40 kilometers and the submarine itself
holds approximately 16 of them now I
know you might be thinking near
of all these submarines are a little bit
older compared to some newer things on
the block well as a matter of fact
Sweden thinks that these are extremely
effective that they can keep them until
about 2025 in which after that they aim
to be replaced by a new type of
submarine known as Project a 26 now
here's the thing that I find that's very
amazing about this submarine is the fact
that during a war game in 2004 it was
capable of outwitting the entire US Navy
that was taking part of the war game and
it was for over a year long it was
really insane to give you the backstory
in 2004 the HS WMS Gotland was sent to
the United States for a war game
simulation this war game commenced on
the west coast starting out of San Diego
and crazy part is in 2005 although they
had been taking part of this war game
for an entire year the US Navy had no
luck in finding the Gotland and because
the United States knew that there was a
problem with the way that they detected
subs they were like wow we were really
determined to find the submarine so we
got a lease it for another year and it
was actually in 2005 that the Gotland
sub managed to slip past many of the
battle groups which included ships
planes and anti submarine detection
objects and was capable of firing as
several torpedoes or as I said taking
several photos at the new 6.2 billion
dollar aircraft carrier known as the USS
Ronald Reagan and as a matter of fact
this submarine was so advanced and so
efficient that it was capable of
destroying almost all of the nuclear
submarines that were in the war game hmm
and of course nowadays the submarine is
now back in the hands of Sweden and to
give you an idea of how much one of
these submarines cost it's approximately
around a hundred million dollars which
is relatively close to the price of an
f-35 and as a matter of fact just on a
side note considering it is related when
it comes to the AIP system Sweden is not
the only country to have submarines that
have this type of propulsion engine this
is because the cockin company has
allowed Japan this technology and the
ability to build these subs at least on
a lease system so they
you have it guys that is a look at one
of the most advanced submarines in the
entire world so what are your thoughts
on this guys let me know down there in
the comment section below do you think
this is one of the most advanced
submarines in the world and much better
than nuclear-powered ones I will say
this when it comes to nuclear-powered
they do have a much longer range whereas
unfortunately these diesel electric
engines don't have the mileage they got
to get refueled all the time so that is
kind of a downside to the Gotland class
sub but your thoughts down there my name
