Submarines - Extreme Technology - Big Bigger Biggest

At 171 metres long, the USS Pennsylvania is the biggest submarine in the US Navy. It can dive deeper than a thousand feet, sail for 20 years without refuelling, and remain submerged for up to 6 months. The vessel carries a crew of 155 men and a deadly nuclear arsenal. The film investigates how this submarine was made possible through a series of six historic engineering breakthroughs. We explore the inner workings of six landmark submarines, including the tiny Turtle and colossal German U-Boats. Each features a major technological innovation that allowed engineers to build bigger submarines, including the development of underwater breathing, torpedo’s, missile launch systems, and stealth technology. Using computer-generated imagery this film reveals the incredible stories behind these machines and the inventions that have allowed them to grow in size. Six ingenious leaps forward enabling submarines to evolve, from BIG, to BIGGER, into the US Navy’s BIGGEST.

As a crew member on the USS Growler, SSG-577, we served up to 3 months per mission. This was a diesel electric (batteries) boat where air, water and food were all at a premium. Like the "leap 5" boats in this excellent video we had to surface to launch our strategic Regulus missile AND guide them to their designated targets with radar. Upon release of the Polaris boats information we were green with envy, where they had gold and blue crews who swapped every other period at sea we we had black and blue crews (no swapping).

Chapter timestamp/footnote for "32:08 Nuclear Strike - USS George Washington "mentions CVN-73 (CV = Carrier Vessel/Aircraft Carrier, N = Nuclear Propulsion); I think you meant to put the hull designation of the similarly-named submarine instead. The one you're mentioning is SSBN-598 (SS = Submarine/Submersible Ship, B = Ballistic Missile, N = Nuclear Propulsion). I love the video! I used to serve on the same class of submarine featured in this video (SSBN-738 / USS Maryland).

I had the good fortune to be sail boating off Maui when a Los Angeles class submarine surfaced in the waterway between Maui and Lanai. It cruised past me majestically, and then another surfaced and cruised near the first submarine. A few submariners were on deck of both submarines. I lost site of them when I rounded Polihua Beech to continue my day sail. But it was a highlight of my 5 years on Maui. All my nearly 6 decades living near Bremerton, never saw one. Go live on Maui for a few years and see 2 at the same time. Fricking awesome!

As a kid I grew up on the beach near Seattle where the Bremerton ship yard is. They would take submarines out in Puget Sound for testing and I would take my 16' ski boat out to watch them. I would be paralleling the submarine, at a distance, when all of a sudden this large, noisy plume of water would spray up meaning the submarine was getting ready to dive. I would tag along and watch it go under until you would never know anything was there. It was kind of creepy, but cool.

First type U-boat in human history that was from the drawing board designed as meant to be operated 99% underwater rather than as a surface ship, like the earlier U-boats that mostly used to dive for rather short amounts of time, and only to evade destroyers and such... the Type XXI on the other hand, was pretty much designed and built to do everything... while underwater.

I used to work on the periscopes on the Los Angeles class subs. I thought these boats were big, until I got to see an Ohio class “boomer”. Now these are big boats. That was back in the 70’s and 80’s. When I retired in 92 the newer scopes didn’t even penetrate the “people tank”. These were inside the sail. They had cameras instead of actually seeing the light coming throughout the tube section to an eyepiece. You just looked at screens. Pretty neat. I got to see into the reactor once, now that topped everything. The only thing they would run out of underwater was food. Submariners are very unique people, it not just for anybody. I almost went that route. All are volunteers. Highly intelligent to start with, and they do years or training.

He's using a drill designed to penetrate wood, as that was the expected material - not too surprising since all vessels at that time were of wooden construction.

Submarines, (and undersea combat) is the closest we’ve gotten here on earth to space combat. Unlike on land, in the deep ocean and in space, the enemy can come from literally any direction.

[@GlamorousTitanic21]

@@andrewsocial9309 in air combat, and with modern sensors and visual scanners, for the most part you can see your enemy coming from miles away. In the deep ocean or space, it’s pretty much impossible to see your enemies location with the naked eye.

[@ihavenocommonsensebut2008]

@@GlamorousTitanic21 well i guess space compensates that since someone could be shooting you down from a distance like a moon😂

[@bigtyke3058]

You can see where your enemy is coming from underwater too

[@nyankittyxp4521]

@@GlamorousTitanic21 think about what you said. That’s exactly what space warefare would be like. Blind to everything, unlike Ariel combat.

[@Zomby_Woof]

You aren't blind at all. You just have a different way of seeing, primarily via sonar. You build a literal map of what is around you. And when your boat is quieter, and your sonar more sensitive, and your stack operators better trained with much more experience than the bad guys, the idea of combat isn't scary at all. A real world combat scenario between a US and a Russian sub would go something like this: US sub CO: Is the target solution still up to date? US: Aye aye. Per standing orders we've been in their baffles since they left port. US sub CO: We've just received orders to engage. Flood tubes 1 and 3 and fire when ready. Helm 20 degrees down and hard right rudder on my command. Russian sub sonar operator: Captain, we have a contact directly aft. It's Death.

What a unique use of fluid mechanics and how cavitation perform mind blowing role in submarine and also love the great engineering who invented such a horrible degsin . Love from Pakistan

Yes bro you are right. I'm currently studying about fluid mechanics it is very useful.

I completely enjoyed this. I learned a lot of good information. Thank you

Excellent history lesson. Thank you.

👍👍👍 YEP.

[@DodgyDaveGTX]

There's a cracking BBC crime drama miniseries set on a submarine called 'Vigil'. It does a pretty good job of conveying the tension that's inherent within life upon a submarine (as well as the excellent writing/acting of course lol)

Very interesting innovations throughout history

[@RivetGardener]

This is a fascinating video, and love the explanation graphics. Nowhere, ever does any information offer that nuclear subs can dive over 600 feet. Yes they can I am sure; past 2000 so I have heard.

[@RogueReplicant]

That's classified af

[@OneEyedJacker]

Submarine rescue submersibles are rated for 2000 fsw. There’s a hint.

Dude the voice just added more power to the submarines

National Geography used to be a great educational platform for young and old, ...but not these days. Much had changed since the last release of "Big Bigger Biggest". I think the time has come for us to petition National Geography to consider them and make the next series of "Big Bigger Biggest".

[@mattgosling2657]

That's mind blowing to think just one single sub carries more destruction than both world wars added together, that's mind boggling. How many subs in this class does the US have?? I'm sure we probably must have some similar here in our British navy too.

[@logannc4om573]

The UK Vanguard class can carry 16 nukes, you have four of them. You have 10 total nuclear powered submarines. Our Ohio class can launch 20, we have 18 of them, and 68 nuclear powered. Cheers, dad.

[@andy-mb3nn]

The guy said that about just one missile the sub can launch. And it has a full rack, loads of them. Probably enough to light the whole world on fire.

[@dolfinwriter5389]

There were 18 OHIO class SSBNs operating at one point before 9/11. Four were to be decommissioned, but were instead overhauled and converted into SSGNs. Instead of potentially 24 nuclear tipped ballistic missiles, they each now carry 154 Tomahawk cruise missiles, plus they now have lock in/lock out systems for SEAL teams to do covert ops from a submerged platform. So now we have 14 operating. Supposedly there is a new class of SSBNs in the works because those boats are getting really old, but I think getting Congress to appropriate funds at this time is going to be a challenge beyond imagination. I think they will need to ____ or get off the pot soon, because old boats are very maintenance intensive, and parts sometimes difficult if not impossible to obtain from companies that have either been acquired or gone out of business entirely.
