  • [missile firing]

  • [machine gun firing]

  • [missile exploding]

  • David Marquet: What?

  • Crazy.

  • I'm David Marquet,

  • former nuclear submarine commander,

  • and I'm gonna watch some submarine clips,

  • and we're gonna rate them for realism.

  • Officer: Torpedo!

  • The Americans are shooting at us again.

  • Jonesy: Pitch is too high.

  • The torpedo's Russian.

  • [torpedo firing]

  • David: Yes, you can tell what kind of torpedo it is

  • by the sound that it makes,

  • and all different torpedoes have slightly different sounds.

  • So, one of the things we do is study

  • all those different sounds to help us out.

  • Officer: Conn, sonar, new contact, Sierra 4-1.

  • Alfa-class Soviet submarine.

  • David: Alfa-class Soviet submarine.

  • It sends shivers up my spine!

  • The Alfa was this crazy submarine

  • that the Russians built back in the '70s.

  • People were trying all kinds of different things.

  • They had a titanium hull.

  • They used liquefied lead to cool the reactor,

  • if you can imagine such a thing.

  • It was the fastest, deepest-diving submarine ever.

  • Basically it's like a Miyata with a Corvette engine.

  • It was a crazy submarine.

  • Officer: Weapon enabled on the far side of the target.

  • It passed Red October before it armed.

  • David: If you turn your torpedo on too far out there

  • because you're trying to get as close as possible

  • and you overshoot, you missed.

  • Ramius: Melekhin, more speed.

  • Melekhin: Negative.

  • You're already running 110%.

  • Ramius: Then give me 115%.

  • David: No, you don't do 115% on a reactor.

  • You do 100%. Point zero. [laughs]

  • Officer: They didn't shoot at us.

  • I can't attack a Soviet submarine without authorization.

  • David: That's right.

  • Rules of self-defense don't let you do that.

  • You see how Sean Connery

  • and Scott Glenn, playing the two submarine commanders,

  • they're, like, cool as cucumbers.

  • These guys are within a few seconds

  • of maybe getting blown to bits.

  • This is exactly the way submarine commanders are.

  • Mancuso: You're heading straight into that torpedo.

  • [torpedo firing]

  • David: It's a highly unlikely maneuver

  • to actually work, especially twice.

  • And the torpedoes would never be that close together,

  • so that, it loses some credibility.

  • But overall, the sense of

  • not really knowing what's going on,

  • the sense of having to make decisions,

  • the sense of this cat and mouse is all really good.

  • When I joined the submarine force,

  • I didn't come from a military family.

  • My mom's like, "What do you do?"

  • And I'm like, when this movie came out,

  • I'm like, "Mom, watch this movie! This'll tell you."

  • Eight out of 10.

  • [tense music]

  • [man screams]

  • [glass breaks]

  • We don't use glass on a submarine like that.

  • [laughs] And that's why.

  • [submarine crashing]

  • Considering these guys just drove into the bottom,

  • they're in pretty good shape.

  • Unfortunately, we kind of know what this looks like

  • because in 2005,

  • a US nuclear submarine did hit the bottom.

  • This was a glancing blow.

  • 98 of the 135 people on board

  • suffered some sort of injury.

  • It was very bloody on the submarine.

  • A lot of contusions, broken bones.

  • And this would be much worse than that,

  • because it went straight down.

  • They were going straight into the bottom.

  • And so I think letting everyone sort of be OK,

  • yeah, we saw some people bumping around,

  • but basically everyone was OK afterwards.

  • Of course you can't have a movie if everyone dies.

  • That's the end of the movie.

  • The sense of what it's like when you turn vertical, though,

  • that's pretty good.

  • So I'm gonna give it a six out of 10.

  • You don't want to do this, by the way, on your submarine.

  • [explosion]

  • [man screams]

  • Why that torpedo just fell over kind of that easy,

  • it looked like there was a cable cut.

  • These things are strapped down in multiple straps.

  • It's really hard to dislodge them.

  • And then the other thing is,

  • what they're showing here is pretty accurate.

  • It takes a lot for the weapon to go off,

  • and the thing falls and bounces;

  • the weapon's not gonna go off.

  • You hit it with a hammer; the weapon's not gonna go off.

  • You heat it up; the weapon's not gonna go off.

  • These things are designed so that

  • it takes a very specific sequence of operations

  • to make the actual warhead go off.

  • So, these are torpedoes,

  • with the classic propeller on the back,

  • and they're designed to go sink other ships or submarines.

  • Submarines also can carry missiles that can attack

  • land targets and missiles that can attack other ships,

  • and also mines that would lie in wait for the bad guy.

  • It only takes one of these modern torpedoes

  • to sink all but the very largest warships.

  • It's a space that every crew member

  • on the submarine would have access to

  • and would be knowledgeable about.

  • The reason is because if there's some sort of a casualty,

  • we need to muster the entire crew to go find it.

  • The philosophy on a submarine is, "One crew, one fight."

  • So with very few exceptions,

  • the entire crew has access to the entire ship.

  • I'm gonna give it a seven out of 10.

  • [menacing music]

  • [submarine explodes]

  • Barney: Mayday! Mayday! The engine room has sprung a leak!

  • David: Now, this scene from "The Simpsons"

  • sends shivers up my spine,

  • because this is the worst fear

  • of all submariners, flooding.

  • At deep depth, the water comes in very, very quickly,

  • and you don't need to flood the entire submarine.

  • Here's what happens.

  • Let's say there's water in the front part of the submarine.

  • That part of the submarine starts to get heavier,

  • and then the submarine starts to tip down like this,

  • which means that the water in the submarine

  • rushes more towards the front,

  • and it makes it even heavier and tips down even more.

  • And so what happens is now the sub,

  • you end up like this.

  • And when you're like this,

  • your ballast tanks don't work anymore.

  • You can't use the air to blow the water out,

  • because the air will just go out the side.

  • This is how you die in a submarine.

  • And if you saw the movie "Titanic,"

  • that's how that ship sank.

  • And you remember at the end of the movie

  • as the ship was sinking, the Titanic was rising up,

  • and that's because the water was cascading

  • from compartment to compartment to compartment.

  • It's called the free-surface effect,

  • and that's how you die on a submarine.

  • It's not pretty.

  • Now, if you're taking on water like these guys are,

  • the first thing you're going to want to do

  • is come as shallow as possible.

  • That does two things for you.

  • No. 1, the pumps that are pumping off the water

  • have less pressure to pump against,

  • so you're pumping off faster

  • and the water coming in has less pressure behind it.

  • Easiest way to stop flooding on a submarine,

  • because most of the water inside a submarine

  • is coming in through pipes, is we have these valves

  • that we can shut. Isolate the system.

  • Now, here, it looks like it's next to a tank

  • or maybe even the hull. In that case,

  • it's a very, very difficult problem,

  • because when you get a leak,

  • that water is spraying in so hard.

  • It's harder than any water cannon you have ever seen.

  • And they show it here; it's trickling in

  • like a limp garden hose!

  • There's no way!

  • So, you're pushing against the pressure

  • to put an earring pin in there? No.

  • The most realistic thing in this whole scene

  • is the guy underwater drinking beer.

  • So I gotta give them, like, at least

  • a three, though, for trying. [laughs]

  • Morozov: From here to here.

  • Robinson: Which means we are on one of these two ridges,

  • or we'd be crushed.

  • David: Yeah, now, these charts are very accurate.

  • You can see they have contour lines,

  • and for a body of water like the Black Sea,

  • which humans have operated in for a long time,

  • it's probably very well mapped. That's probably accurate.

  • Robinson: No, the Black Sea is anoxic at depth. No oxygen.

  • David: Yeah, the Black Sea is a very special body of water.

  • It's basically like a bathtub,

  • and it has very little interaction,

  • and you have rivers flowing into it,

  • and then that flows out to the Mediterranean.

  • So, deep, there's a layer

  • where the deeper water is anoxic.

  • There's very, very little oxygen.

  • And as a result, there's little decay.

  • Now, I'm not sure it's perfectly preserved,

  • but it's just like finding human remains in bogs.

  • They're very well preserved.

  • Whether they can use the driveshaft or not,

  • I don't know.

  • But it's still overall nine out of 10 for realism.

  • That's true.

  • Ramsey: We have rules that are not open to interpretation,

  • personal intuition, gut feelings,

  • hairs on the back of your neck.

  • Hunter: Captain.

  • Ramsey: We're all very well aware of what our orders are

  • and what those orders mean.

  • David: This is exactly right.

  • You wanna side with Denzel,

  • but what Gene Hackman is saying right here is exactly right.

  • These guys are trained on this 100 times,

  • including the exact kinds of errors

  • that they're seeing right now.

  • But then he takes it too far.

  • Ramsey: Cob, arrest this man and get him out of here!

  • Hunter: Capt. Ramsey, under operating procedures

  • governing the release of nuclear weapons,

  • we cannot launch our missiles unless both you and I agree.

  • David: That's right.

  • So, Denzel doesn't need to get in a big argument,

  • he just needs to say, "I'm not gonna announce that."

  • The rest of the crew knows.

  • The procedure is if they don't hear both voices,

  • those missiles aren't gonna fly.

  • Gene Hackman doesn't have the right to remove him

  • from his position because he doesn't agree with him.

  • It's set up so that two people

  • independently have to make the decision

  • to launch nuclear weapons. It's such a huge deal.

  • Ramsey: I order you to place the XO

  • under arrest under charges of mutiny!

  • David: Now, this is all just a fantasy

  • that some Hollywood people dreamed up.

  • First of all, it's not mutiny,

  • because Denzel is not collaborating with anybody.

  • It's just, he's by himself.

  • Mutiny would mean he has a whole bunch of,

  • or at least one other person with him.

  • Denzel can't relieve the captain

  • just because he doesn't agree with the captain's decision.

  • Commanding officers can get relieved

  • for, for example, a medical reason,

  • he's incapacitated.

  • Having a disagreement about something

  • is not a legitimate reason

  • for relieving your commanding officer.
