10 Deepest Diving Operational Submarines in the World | Submarines With Maximum Test Depth

As a former US submariner, I would say that the only people that know how deep a submarine can really go are dead.

Technically, all submarines can reach the bottom of the ocean.

500m? Ocean gate: Hold my game controller 😮

All submarines have a secret performance margin for use only in wartime.

Pray for kri nanggala 402....indonesia submarine...53 people died...pray for them all.😔😔

Keep in mind that "test depth" is deceiving. The builders design them to withstand a certain pressure for a set amount of time, yet many Kriegsmarine Uboat captains in the Atlantic reported exceeding even the estimated crush depth of their submarines on several occasions without the pressure hulls failing while evading depth charges from overhead destroyers. The true combat diving capabilities of all military subs in service is absolutely classified. Who in their right mind would develop something that is supposed to be a step ahead of their rivals and then make that information public? Nobody.

When out to sea, we always remember this. Two things- #1. The fire department will never get to you fast enough to help, no matter the situation. #2. The furthest you will ever be from land is only a little over seven miles, dry land is another consideration.

who seriously believes these figures. The official figures are kept secret.

I was a Sonar Tech aboard the USS Henry M. Jackson SSBN 730...A Trident submarine...This popped up recommended by YouTube. I only began watching because, as many others have commented, the Test and Crush depths of at least a U.S. Navy submarine are classified. Granted, of the 3 levels of classified material, Confidential, Secret and Top Secret, test depth of a boat is merely Confidential, and is not difficult to discern. But for a YouTube poster to claim to have such knowledge as this for 10 different military submarines is ludicrous.

I am here for some reason too.

Every boat is as good as it's welds, and every boat, same class or not, has a unique crush depth. It isn't unusual for a submarine to be capable of twice it's "test depth" Our boats back on the 30s and 40s would, in a pinch, go well beyond their rated depths.

Love💗🇷🇺Russian peopel for Saporting inda 🙏🙏😊 love from india🇮🇳🇮🇳

Russia's deepest submarine is the A-12, which could dive to a depth of 6,000m (about 18,000 feet)

Komsomolets K278 reached a test depth of over 1000m and doesn’t get crushed until 1500m. Titanium is strong as hell. I’d imagine if the ships of today needed to go that deep, they'd survive.

Thank you for the info & video!!

The titan topped all of these

You showed an "astute" class british attack sub for a Chinese sub lol. %hit happens lol.

Never gonna give you up. Never gonna let you down Never gonna run around and desert you Never gonna make you cry Never gonna say goodbye Never gonna tell a lie and hurt you.

submarines are the scariest thing i know about. the fact that they could be anywhere, and we don’t even know about it is terrifying to me
