Original subtitles

Sonar contact with enemy sub has been lost.

It's playing it safe, cutting the engines...

and seeing what we do next.

We have a sound profile.

A Yankee?

No, a Japanese diesel. The Yamanami.

The Yamanami... That damn pest, huh?

They're right above us!

What?

Range: Forty... Thirty... Twenty...

Crash dive! Make depth 600!

Collision! Collision!

Collision! We hit them!

Don't panic! Damage report!

Conning tower hatch, damaged!

Taking water, but minimal!

Reactor, stable!

They got the worst of it. Where are they?

To starboard, going down.

Depth: 500.

Looks like their ballast pumps are damaged and they can't surface.

The Yamanami's rated to 700 meters.

They're 100 meters away from crush depth.

680 meters...

690 meters...

700!

Implosion!

I'll begin the briefing. At 16:30 hours, near this ocean sector...

a large heavy oil slick was sighted.

While a joint U.S. -Japan investigation is underway...

it appears that, due to an accident...

the submarine Yamanami imploded at a depth of 700 meters.

In short, it was crushed and sunk due to extreme water pressure.

So, were all hands lost?

- That still hasn't been confirmed. - And the cause?

There are reports that it struck a Russian nuclear sub.

That's a possibility, but the Russian government...

has yet to issue a public statement.

Chief of Staff, assuming a nuclear sub was involved...

is there any concern over radioactive contamination?

There's no evidence of any contamination.

I'm sorry, but for the duration of this investigation...

anything more than I've told you has been classified.

Speed: 12 knots.

Heading: 2-1-0.

Make ready to dock at berth number three!

Make ready to dock at berth number three!

That's all for my report on our training run, sir.

Well done. So, do you have the tape?

Yes, sir.

The sound of the Russian sub hitting it is on here?

Our hydrophone array was 70 klicks from where it happened...

but it was still barely within analysis range.

But, to have lost such a valuable officer...

Oh, you really believe that?

Pardon me, but did you check it out yourself, sir?

No.

It was the Americans who recovered the remains of the sub and her crew.

I can't trust information that someone else has gotten for us.

Well, I do!

You're dismissed.

You both went to the Academy, didn't you?

Kaieda and I were equally promoted from the same class.

Not quite right. The general staff...

decided to give him a special two rank promotion.

Oh? Nice reward for losing a boat.

Don't speak ill of the dead!

Kaieda will be remembered as an admiral!

The dead, huh?

This is the Russian sub's screw and pinger.

The Yamanami's engines are stopped.

There's the collision.

It's lighter than I thought it'd be.

The Yamanami goes down...

Implosion.

That's a sound you can never get used to.

Wind it back.

This wave form's the Romanov.

This one's the Yamanami.

It just stopped its engines.

The Yamanami should have seen the collision coming at this point.

Kaieda collided with the Romanov on purpose.

Wind it back another ten minutes.

What do you mean?

Kaieda is one of the best sub commanders there is.

He wouldn't die just from tapping that Russian boat.

But they found the wreckage.

Have you seen it yourself?

What are the only things a submariner trusts?

His own eyes, ears, and intuition.

Exactly!

And my intuition says that Kaieda's still alive.

This is 12 minutes before implosion.

It's faint, but here's the Romanov's wave form.

And the Yamanami?

Can't isolate it.

I picked it up with digital processing, but...

This background static is normal surface noise.

What's that?

A humpback whale's cry. It has a calf, too.

This, too?

The same. After this, it's just...

Wait a second!

I'll pull this out of memory.

10 minutes before the implosion, I heard something.

Can you ID it?

I don't believe it...

It sounds just like a hatch being closed.

- A hatch? - Impossible! UNDER water?

On the surface.

They surfaced once so that all hands could escape.

Then the now unmanned Yamanami continued on autopilot...

and struck the Romanov.

Nanba, can you prove that sound is a hatch closing on the surface?

Not with this toy. Maybe with the super computer at HQ.

The engineering lab at SDF headquarters?

We're betting the farm on this one.

Just find out the truth, no matter what it takes.

Freeze! Military police!

Halt! Halt!

Nanba!

Chief, these guys are serious!

What did the skipper find out?

I think something that'll shake up all of Japan.

You were good enough to score kills on...

the carrier Carl Vinson during the RIMPAC maneuvers.

I was really proud of...

how you threw the American brass into such an uproar.

So you were actually going to kill such a valuable officer?

Don't be ridiculous! This is a national defense secret!

Unfortunately...

Your intuition is correct. Kaieda's alive.

Then why did he deliberately ram that Russian sub...

and sink the Yamanami?

Because Kaieda and his crew have a special assignment.

Special assignment?

Japan's first nuclear submarine.

A... A Japanese...?

A super-advanced sub secretly developed by the U.S. And Japan...

utilizing the cream of Japanese science and technology.

But, a nuclear sub for Japan is...!

That's why it will be officially part of the U.S. Far East forces.

To gain nuclear sub know-how, the crew will be all Japanese.

I see... Kaieda and the Yamanami's crew...

Captain, all hands have evacuated.

All that's left is to engage the autopilot.

We all have friends and family.

However, they must be forever separated from their loved ones.

But they are the chosen.

The price for being Japan's first nuclear submarine crew.

Chosen? They're the chosen?

They chose him to command our first nuclear sub instead of me? Shit!

Fukamachi!

Sir! Even if it was on orders...

you'd trust a man who'd sink his own boat with a nuclear sub?

And you wouldn't for the chance to have one?

Are we clear on this? This is a state secret!

None of you will be allowed any leave!

Wait for this to be settled!

Its active radar scanner lets it fly several meters above the surface...

and lock onto even long-range targets in any weather condition.

The vessel has eight missile launchers...

and, with 50 shots, double the torpedo load of any other sub.

It's an honest-to-God sea monster.

This ultra-modern sub combines the best of the U.S. And Japan.

We've assigned it its code name. It will be called the Sea Bat.

I want to complete your training in 20 days...

after which the sub will be handed over. Any questions?

I have a request.

We'd like to make the final checks ourselves...

before the shakedown cruise.

Unnecessary. The final servicing is complete.

We haven't made our final inspection yet.

Don't trust us dumb Americans to check it out right?

No, but please remember that if anything goes wrong...

it's our asses that'll be on the line.

Wanting to make a personal inspection...

is common sense for submariners of any country.

For one month, they trained as part of a U.S. Nuclear sub crew.

And, during their 20-day training duty...

the Japanese sailors surprised us with their excellent skill.

As commander of the U.S. Pacific fleet...

I'm here today to offer my deep respect and thanks...

to JSDF Commander in Chief Sonezaki...

and to Captain Kaieda and his crew of 70.

Captain Kaieda, it's an honor to...

have the Sea Bat as part of my Pacific fleet.

I'm honored, Admiral Steiger.

This is Capt. David Ryan, who will be...

on board the Sea Bat as a U.S. Navy representative.

Captain.

May this joint venture strengthen...

the alliance between the U.S. And Japan.

Well, here's to the successful trial voyage of the Sea Bat.

Cheers!

Hey, Captain, that Kaieda's a typical Japanese, isn't he?

You can't tell what he's really thinking behind that smile.

No, he's just a very careful man.

There were two candidates to command the Sea Bat.

There were two guys who scored 5 kills...

on my Carl Vinson during the RIMPAC maneuvers:

Kaieda of the Yamanami and Fukamachi of the Tatsunami.

Both are excellent commanders...

but their personalities are dead opposite.

Fukamachi's reckless while Kaieda's very cautious.

They ended up choosing Kaieda's cautiousness.

Forgive me, Kaieda.

I wanted the farewell party for our first nuclear sub...

to be a national celebration. Japan deserves the recognition!

Sir, I'm overwhelmed.

Japan paid to have it built!

To assign it to the 7th fleet and code name it the Sea Bat...

It's insulting!

Like a submarine, a bat travels in darkness using ultrasound.

I think it's a very appropriate name.

- Captain! - Right.

They've completed the final checks at the dock.

Pardon me while I check it over myself.

9000-ton displacement.

Capable of a maximum depth of 1000 meters...

with its titanium alloy hull.

An 80,000 hp generator powered by an S8G nuclear reactor.

Armed with 50 nuclear-capable torpedoes or missiles.

Propulsion provided by a seven-blade skewed screw...

capable of up to 40 knots with cavitation suppression.

Every point on her checks out clear.

Tomorrow, with neither a military band...

nor family members to wish us well...

the world's most accursed ship shall set out.

Sir!

Yamanaka, I don't consider this an American vessel.

With nearly unlimited power from nuclear fission...

and by extracting oxygen from the water...

we could travel 200,000 km without having to surface.

Pretty much an all-around unstoppable boat.

But nuclear subs do have their disadvantages.

Disadvantages?

Nuclear generator turbines are noisier than a diesel.

But, compared to the Sea Bat's...

a Russian sub's are like a subway train!

14 hours out and all is well.

How long to the target point?

At our present speed of 20 knots, our ETA is 9:30AM tomorrow.

We're to rendezvous with the nuclear sub New York at 10:00AM.

At 10:30AM, we take a westerly heading and return to Sasebo.

All according to schedule.

Aye. Understood, Captain Ryan.

Captain, the New York isn't...

the only sub waiting at the target point.

It's swarming with nuclear subs.

They probably want to get a sound profile on the Yamato.

If they get a profile, it could make things harder.

Should we change course now?

No, they're bound to get a profile sooner or later.

Then comes the showdown.

So, it's time.

Screw noise ahead, bearing to starboard. Range: 4500

Not even a minute off. It's the Sea Bat!

I see... It's a quiet little boat.

Stop engines and get its sound profile.

Give them some active sonar.

Captain, I'm reading overlapping signals.

I'm positive there are more out there with the New York.

Captain, the New York seems to have some big whales for friends.

#2 tube, ready a screamer torpedo.

- #2 tube, readying a screamer. - A screamer torpedo?

Fire.

Wait!

The Sea Bat's just fired something at us!

Speed: 40 knots! Range: 1500 and closing!

A torpedo?

Start engines! Evasive!

Engines to full. Make depth 700.

Mutiny.

I'm relieving you of command of the Sea Bat.

Mr. Yamanaka, confine Captain Kaieda to his quarters.

Yamanaka! Yama...

I'm in command here, Captain Ryan.

And this vessel is not the Sea Bat.

It's the Yamato.

All right! Got one!

It's big! American nuke sub-class!

Probably more like a little diesel.

Get lost!

Maybe it's a Japanese nuclear sub.

Sub hunters?

It's not a training exercise. That's a scramble!

Looks like something's just happened.

Today, at 10:30AM, in the vicinity of Ogasawara Island...

the Sea Bat's crew mutinied and deserted.

- Mutinied? - Deserted?

Admiral Steiger has ordered that the Sea Bat be captured...

and her crew held for a U.S. Court-martial.

If worse comes to worst, it's to be sunk.

Sunk?

I see... These are all the heads of the Sea Bat Project.

Even the old man they call the Shadow Prime Minister.

With them all together, this is a shadow Defense Assembly.

To save time in letting us get to the bottom of this...

I'll be totally honest. I don't know what Kaieda's up to.

- Is he defecting? - Impossible!

Kaieda comes from generations of naval elite.

His loyalty and motives are beyond question!

Look, we have to figure out what the government's position is!

Our only option is to keep from getting in too deep on this.

Leave it to the Americans.

That's irresponsible!

The Sea Bat represents an enormous investment of 2.3 billion dollars!

The Americans will demand Steiger's resignation. For us...

This will end up bringing down the current administration.

And just what are our self-defense forces for?

Mr. Akagaki?

Is it possible for our forces to...

capture the Sea Bat before the Americans do?

It would be difficult.

If we scrambled the entire maritime SDF, then maybe...

Then do it!

Japan has to solve this by itself!

Sir, if we get the Sea Bat, what do we do with it?

Just turn it over to the Americans?

Not before we study it!

It may be "our" first nuclear sub...

but the drive and weapons hold a lot of American know-how.

To allow us to create a completely Japanese-built nuclear sub...

we need to secretly capture it before the Americans do!

- Oil pressure, check! - Helm control, check!

Release probe! Cast off!

Prepare to set sail!

Our target is a new class nuke capable nuclear sub, huh?

Ordering us to catch it is like telling us to get a humpback whale.

To fire a torpedo and then run...

He must be serious.

Kaieda... He wouldn't defect or go insane!

I've got an IR trace. It's reactor coolant water.

It's surfacing.

Viking to command! Submarine matching the Sea Bat...

has been sighted in the vicinity of Yap Island!

Speed: 15 knots and cruising on the surface.

Captain, I'm getting a signal from them!

Good morning, U.S.A.

Underway on nuclear power.

The same message that the first nuclear sub, the Nautilus...

issued in 1955 as it sailed under the Thames River.

Playing copycat, huh?

Yes. I wanted to say it.

Considering this is Japan's first nuclear sub.

Is that rational to surface just for that?

I think it is.

If you're sane, you'll want money next.

Gonna just sell this boat to some terrorist state?

Attention Sea Bat! Return to Sasebo at once!

If you disregard this order, you will be fired upon!

Or maybe this is a plot of the Japanese government.

Steal an American nuclear sub for your defense?

Ridiculous! What can Japan do out from under America's umbrella?

Our defense treaty, you mean?

As much as I believe America would defend Japan...

I'm not naive.

Captain, do you think they won't fire as long as you're on board?

Don't you hear it? The symphony that proclaims an ally an enemy?

A 350-pound antisub bomb.

- They're bluffing! - Incoming, starboard high!

Captain, this is the American Way.

Gentlemen, you can argue whether a "sea bat" is a bird or a beast...

but the commander of the Pacific fleet has decided...

that it's short for "sea battle!"

We'll see if it also deserves the title of "enemy."

We'll give the sub drivers the first crack at it.

I'd like to let the guys who allowed...

the Sea Bat to escape a chance to redeem themselves.

The honor of our fleet is in your hands.

Richard Boyce...!

That yellow bat won't make fools of us for long!

Orders from command, received!

Okay, reel in the radio buoy.

The U.S. 7th fleet is bottling up the Pacific routes.

The Tatsunami is to make for the Barrington Straits...

near the Taiwan Strait.

Chasing our own boat and we still have to wait on the Yanks' asses!

ETA?

At 20 knots, 15:00 today.

10 knots will do.

Why waste the batteries?

Make depth 100, heading 2-6-0. Speed: 10 knots.

I want the crew to get some rest.

Begin individual sleep rotations.

Don't think we can catch the Sea Bat, Captain?

Unfortunately, we'd never make it.

The oily-smelling Tatsunami's no match, huh?

Listen, you idiot! Don't you know...

that smell's the proof that this boat's a diesel?

Kaida surfaced. Why?

Gave his position away and even said hello to them.

Uncharacterically reckless...

More like one of your moves.

I don't know what he's really after...

but I'd lay odds he's headed north!

We've been holding for 3 hours at 1000 meters.

If he was headed for the Indian Ocean...

he wouldn't need to rest here. What are you up to, Kaieda?

You like Mozart, Captain?

Mozart's Symphony #40.

I love this one.

When I hear it, I feel like a fish swimming free in the ocean.

Any sign?

None.

There've been no reports of it in the Indian Ocean.

It must still be wandering around here.

Be careful. It could be waiting, engines off and torpedoes ready.

I see. It's soothing.

Like the shake of a Michigan wind is for me.

Never thought I'd hear this 1000 meters under the sea!

Sonar to captain's quarters. I'm getting screw noise.

Bearing: 1-2-2, range: 5000. It's a Los Angeles-class.

Number?

I figure there are a couple more behind it.

What the...?

Captain! I hear a symphony!

A what? Impossible! Down here?

There's no mistake, sir. It's Mozart.

All right, stop engines and get a fix on that sound!

Well?

Bearing: 1-8-0, depth: 800. It's...

It's directly under us!

He's giving a Mozart concert from right under us?

Sonar to captain's quarters.

The New York has closed range and stopped.

It's directly above us, depth: 500.

The other 2 subs 5 klicks behind it have also stopped.

Very well.

All hands, battle stations.

All hands, battle stations!

When I say so, start slowly lowering the cassette's volume.

If you don't shoot first, they'll shoot you.

Relax, Captain Ryan.

I won't shoot a torpedo at that idiot's sub.

Switch over to batteries.

Commence a silent blow on the ballast tanks.

Rise at 3 meters per second.

Rise at 3 meters per second! Ballast tanks, silent blow!

That's the Sea Bat, all right.

Prep torpedo control!

Load tubes 1 through 4! Rig with conventional warheads!

Flood tubes!

He's flooding tubes! Captain, the New York's preparing to fire!

Lower the cassette one notch every second.

That band still playing?

Aye. It's stayed at the same level for 5 minutes now.

Hasn't he noticed us?

Sonar, when I give the word, send out a ping.

When that echo comes back, we'll fire the torpedoes!

Aye.

Sorry you're still on that thing, Ryan...

but I've got orders to sink her!

Kaieda... Turning the music down...

to make them think you're far away?

Okay, ping 'em!

Don't fire! The Sea Bat's right next to us!

WHAT?

Hold this depth.

I see. You closed the distance while lowering the music.

Now our ships can't fire torpedoes. However...

Damned Sea Bat! I thought you were smarter than this.

You think you can stick to the New York forever?

What do we do, sir?

How far is the 7th fleet?

150 km behind and closing.

All right, ahead full!

The New York's moving.

20 degrees to starboard, 5 degrees up trim.

All right, ahead full and shadow him.

Just follow me, Sea Bat.

You're invited to a great party!

This is something else!

The New York, the Sea Bat, the Chicago, and the Dallas!

It's like the Macy's parade!

They're too close together. We can't attack from the air.

This is the captain to all hands.

A few dozen kilometers ahead of us, the U.S. 7th fleet...

the mightiest in the world, is gathered, waiting to destroy us.

Behind us are the nuclear subs Dallas and Chicago.

This vessel is in the most dangerous situation possible.

However, if we manage to get out of this mess alive...

the world will have to recognize us...

as the sub which cannot be caught.

For a submariner, there's no greater glory.

To gain that glory, we're about to initiate our escape plan.

For talented men like you, it should be no problem.

If you carry out my orders quickly...

we'll come through this without any trouble.

Three minutes to rendezvous with the 7th fleet.

10 degrees up trim! Break away from the Sea Bat...

and get ready for a grand entrance!

Captain, wait!

- What's wrong? - Drop speed a little.

I can't hear the Sea Bat now. I think they've slowed down.

What? Jesus! A torpedo?

They wouldn't! They know an explosion would catch them, too!

2 screws in the water!

2 torpedoes, approaching from aft! 45 knots, range: 500!

What?

Sir, evasive!

Ahead full! Right full rudder! Up trim to maximum!

No good! Can't shake 'em! Torpedoes above us!

Range: 200! 150!

100! 50!

They're gonna hit!

Captain, we were damned lucky! Both those fish were duds.

No, they had their warheads removed.

Gimme a damage report!

If we're not, then come about and prepare to return fire!

Reactor and engine, on line!

Screw destroyed! Maneuvering impossible!

WHAT?

The propeller's gone, sir!

Captain...

Dead in the water?

Can it possibly be any more humiliating?

More humiliating than this?

Torpedo chief, well done. That was perfect targeting.

Come about 1-8-0 and make for the Dallas and the Chicago.

Ready the masker.

I just lost the Sea Bat's screw.

They may be using a masker to hide the noise.

Try again.

- Got 'em! - Speed?

40 knots! Range: 1500 and closing!

After him!

We can use a torpedo!

No, we're too close. Besides, there's a better way.

Come about 1-8-0!

I'll nail the little bastard in the ass.

To avenge the New York, I'll stop you dead, Sea Bat!

Both enemy subs moving off. Already 10 km away.

They don't know it's a decoy. You did it, Captain.

A decoy torpedo with...

a screw tuned to sound like the Sea Bat's?

How far is the 7th fleet?

The carrier Carl Vinson is 35 km ahead of us.

It's surrounded by vessels in a 10 klick radius.

Here it comes. If it clears, we should have a nice sunset.

Aye, sir!

20 knots, 10 degrees up trim. Periscope depth.

You're going to surface?

Such confidence...

Looks like America's reputation for being...

the world's policeman is still going strong.

Not even a little nervous?

They'll make you pay for attacking the New York.

Surrender, before they hit you with a missile!

- Surrender? - Exactly.

The weaponry on this vessel won't stop the Carl Vinson!

You still believe that in this day and age?

We're about to see if American confidence is real or for show.

That damned crazy bat...

Is he going to drive right into the middle of the fleet?

Or maybe he's a kamikaze.

Maybe if we gave him a little encouragement...

he'll decide to surrender, instead.

Okay, give the order.

California! Alabama! Commence fire!

We're in range. Send the 7th fleet our message.

What the hell do they mean, "warheads are nonconventional?"

Nuclear torpedoes!

It's a bluff!

But, if there's any chance it's true...!

They could wipe out the entire 7th fleet in an instant!

And what if we give into their demand?

I won't disgrace my Navy for the sake of one damned submarine!

Carl Vinson's speed and heading, unchanged!

Kaieda, command sees through it.

That your trump card's a bluff.

You have no nuclear torpedoes!

Captain, have you forgotten the "final check" we made...

before we left Sasebo?

Yamanaka, take over.

You switched the torpedoes then?

No! You couldn't have had enough time!

Can you be 100 percent certain?

What?

All I'd need is one.

Okay, suppose you have a nuke. You couldn't fire it!

You couldn't, not with the entire world watching!

You're right. Even if I had one, I couldn't use it.

But the power of a nuclear weapon...

is the possibility of using it.

I repeat, the Sea Bat has no nuclear weapons!

Did you arm the Sea Bat with...

nuclear weapons without informing the Pacific fleet?

We made no such plans!

But the Japanese had a chance to load them!

Are you suggesting Japan has developed nuclear weapons?

Kaieda's message certainly suggests it!

You know very well that Japan is a nuclear-free zone!

Spare me the PR!

Does the Sea Bat have nukes or not?

Carl Vinson's heading and speed are unchanged.

Collision in 2 minutes!

- Steady as she goes. - Kaieda!

You really think this will work without a nuke?

What are you doing?

Seeing for sure just how much America trusts Japan.

If America trusts the Japanese government...

For example, if they believe we have no nukes aboard...

then the Carl Vinson will be able to ram the Yamato.

But, if it stops...

If it stops...?

Then America is suspicious that Japan has nuclear weapons.

Understand?

From HQ, sir.

Captain!

All stop! 20 degrees, left rudder!

The Carl Vinson's stopping!

Right full rudder.

We've got a line to the Sea Bat.

This is Richard Boyce, commander of the 7th fleet!

An honor, Captain Boyce. This is Capt. Shiro Kaieda.

You're a renegade ship!

Stand down and leave that vessel immediately!

- Will you comply? - No.

I have a statement to make.

You think you have any right to make one?

In this situation, you've no choice but to listen.

With the end of the Cold War, the United States of America...

seems to have grown used to the role of world policeman.

But, with the threat of a single nuclear weapon...

we've created this standoff.

The possibility of even a single nuclear weapon...

has rendered America helpless.

Do you understand? Times haven't changed at all.

I've turned this 5 km radius chunk of ocean...

into a microcosm of the world to prove this.

The 7th fleet's actions have caught the world's attention.

Even though the Cold War is over...

I'm sure people are as aware of nuclear weapons as ever.

Of course, because the world works this way...

this vessel was built to be the most powerful sub in the world.

Exactly. The Sea Bat is an American nuclear sub.

We recognize that it was born of both America and Japan.

But we are definitely not a renegade vessel.

And we are no longer a part of the 7th fleet.

Then what the hell are you?

We are...

the independent nation of Yamato.

This is our declaration of independence.

In accordance with international law...

we claim a 12-mile territorial boundary.

If our boundaries are violated...

we claim a natural right to attack the invader.

Do you understand, Captain Boyce?

You, America, are violating our territorial waters.

So long as we recognize America as a hostile nation...

we have a right to attack. You have none.
