Ranking Every Submarine on Earth (that we know about)

All the world's (known) military submarines.

There are at least 471 submarines in the world, many of them lurking in the world’s oceans right now. We mapped them all.

very polite of all the countries to line up their submarines for this video

[alext.]

The country with the largest number of Subway restaurants per million people worldwide in 2014 was Canada. I don’t know if this is relevant, since we’re talking about submarines.

[jimalbi]

Spain once had the biggest fleet of warship on Earth.
Today they have 1 sub.

[knpark]

South Korea: has the sixth biggest submarine fleet in the world
Also South Korea: *their submarine fleet is the smallest in its neighborhood*

Some people like to rearrange their furniture, clean their Legos, or just read a book. Johnny likes to rank submarines 😂 my kinda guy

Just remember two things.

1/3 of all navy vessels are in dock for maintenance at any one time. 1/3 are transiting to or from a station, so only 1/3 are patrolling at any one time.

The second thing is…the oceans are really big.

I am from India and let me put the correct Indian submarine count:
Conventional :
1. Kilo class : 7
2. Type 209 : 4
3. Kalvari class : 6

Nuclear :
1. Arihant class : 3 (3rd secretly commissioned)
4th submarine also launched.

So we have alteast 20 submarines out of which 3 are Nuclear.

I'd like to see a similar video comparing air strength and tank strength.
1. It's very interesting to see how each NATO nation has its own special application- like how Greece has a massive tank force and how France has expeditionary capability
2. Its also fascinating to see how Air forces are advancing. Who is using the most modern gen 5 aircraft? How many bombers does each nation have?

“Australia will SOON have nuclear submarines”

My children will be in University before the first one is commissioned… (I have no children yet)

13:51 Minor correction. The replacements for the US ballistic subs (Ohio Class) are going to begin entering service in 2031 (Columbia class). The first sub will be SSBN-826 USS District of Columbia. The SSN(X) program replacing current US Attack subs (Virginia Class) are projected to enter service in 2042 with builds starting in 2034. Thanks for the informative video.

It's crazy to think that today there are less than 500 submarines World-wide, whereas during WW2, Germany alone built over 1100

[camatat]

As a romanian, I can say that we have a submarine too. It wasn't used for the past years, currently undergoin repairs, but I think it still counts as one submarine.

[scbond]

Very odd that you mention both France and the UK having nuclear powered subs and then you move on and say "this is where you'll see nuclear weaponised subs". Both the French and the UK have nuclear weaponised subs.

Shoutout to the cameraman; they chose a great day to shoot this video! 😝💯

It's worth noting that diesel-electric subs aren't entirely inferior; there are good reasons to run them aside from economy or lack of technology. The biggest advantage is that they can be effectively 100% silent if they are stationary, whereas a nuclear boat will always make _some_ amount of noise because it has to run pumps to cool the reactor. The latest U.S. and Russian nuclear boats _may_ be quiet enough to render this distinction almost academic, but it's still there.

There's also some minimum practical size and weight for a naval reactor, which dictates a minimum displacement for nuclear boats. Larger hulls will tend to be more hamstrung in shallower seas, less maneuverable, and present larger targets for active sonar.

Of course, a diesel-electric boat's underwater endurance is such that your adversaries will generally know where they are within a certain radius; everyone knows where the boat is when it's surfaced. You can think of diesel-electric submarines somewhat like a mobile minefield. Air-independent propulsion (AIP) closes that gap significantly; these boats are potentially just as quiet as standard diesel boats, but have enough underwater endurance to make them difficult to track. During multiple NATO exercises, the Swedish 'Gotland' class has famously been able to penetrate U.S. carrier groups multiple times, undetected. This is somewhat terrifying since these boats don't have the technical barrier-to-entry of naval reactors, and are well within the budget of any navy–on the order of $100M, or a bit less than an F-35.

Meanwhile me who's watching this from a landlocked nation and has never seen an ocean before 😢

"...That we atleast know" is such a powerful and scary fact at the same time

[johnjon]

You missed the 4 British Vanguard subs that carry nuclear warheads as a deterrent. French have something similar as well.
