S7-EP03: The Insane Engineering of Nuclear Submarines

This is your Tier SSS unit, Kurumi? A boat? A boat that hides?

A Tier SSS unit should be a Gundam! It should be a beautiful, glorious machine piloted by epic, handsome aces!

Look at the pilots in this sub model. They look cramped, miserable, and they haven't seen the sun in six months!

You are judging a masterpiece of engineering by the aesthetic of the user interface.

You see a claustrophobic boat. I see the closest thing humanity has ever built to a self-sufficient god.

Whatâ€™s so godly about it? The SR-71 could outrun missiles. The B-2 could turn invisible. This thing just... sits at the bottom of the ocean.

I get it, it has "infinite fuel" from its nuclear reactor. But that just means the sad pilots are stuck underwater for longer.

"Just infinite fuel." You say that as if itâ€™s a trivial line item on a spec sheet.

You have completely failed to grasp the thermodynamic revolution that is happening inside this steel tube.

We are not in a boat, Shez. We are inside a controlled, miniature star.

For 300 years, every engine on this planet has been a slave to fire.

You burn a carbon-based fuelâ€”wood, coal, oilâ€”to create heat. Heat boils water. Steam turns a turbine.

This is the logistical bottleneck. The fuel is bulky, inefficient, and requires a constant intake of oxygen from the surface to burn.

A diesel submarine must surface every 24-48 hours to run its engines and recharge its batteries. When it surfaces, it is visible. When it is visible, it is dead.

Admiral Hyman Rickover understood this. To win the Cold War, he didn't need a better torpedo. He needed a better campfire.

He needed a fire that didn't need to breathe.

Okay, so itâ€™s a rock that burns forever. Itâ€™s just a boat with infinite fuel. Whatâ€™s the big deal?

It doesn't "burn." Fire is a chemical reaction. This is a nuclear one.

We are not breaking molecular bonds. We are splitting the atom itself.

The energy density is absurd. A single fuel element the size of your thumb can power this entire city-sized machine for twenty years.

But the heat is just a byproduct. This is a steam engine that burns rocks. The true revolution is what this allows us to do next.

The turbine generates massive amounts of electricity.

What do you do with near-infinite electricity in a sealed metal box?

First, you run seawater through the desalination plant. You create a near-infinite supply of fresh, drinkable water.

Second, you take that fresh water and run it through the electrolyzer. You pass an electric current through the Hâ‚‚O.

And you split the water molecule itself, generating a constant, near-infinite supply of breathable oxygen.

Wait. The reactor makes the power... the power makes the water... and the water makes the air?

It... it creates its own atmosphere?

This is not a submarine, Shez! It is a closed ecosystem!

It is a self-contained biosphere that manufactures its own water and its own air. It is a piece of planet Earth that has severed its connection to the surface.

It does not need the sun. It does not need the sky. It is completely independent of the terrestrial environment.

It can remain submerged, silent, and invisible for as long as it desires.

But... for how long? If the fuel lasts twenty years, can they stay down there for twenty years?

The engineering has reached perfection. The hardware has achieved infinity.

But now, we hit the final, unbreakable bottleneck. The biology.

The constraint isn't fuel. The constraint is food, and human sanity.

A nuclear submarine typically carries enough food for a ninety-day patrol. After that, the crew starves.

So the "sad pilots" I was laughing at... they're actually the limiting factor.

The machine could go on forever, but the carbon-based life forms inside it need to eat.

Correct. We can manufacture air, but we cannot yet manufacture apples.

And more importantly, we cannot manufacture psychological stability.

The limit of the machine is the biology of the crew.

For ninety days, one hundred and fifty souls live in a steel tube, surrounded by crushing black water, running a miniature star, with the constant knowledge that a single hairline fracture in the hull means instantaneous, explosive death.

The pilots aren't handsome aces... they're... astronauts. Exploring an alien world right here on Earth.

They are the ultimate practitioners of Asymmetric Warfare.

A nuclear submarine has one, single, Tier SSS mission objective.

To disappear. To become a ghost. And to wait.

They are the "Second Strike" capability.

If a nuclear war begins and every city on the surface is vaporized, these ghosts remain. They are the planet's insurance policy. The final move in a game that can never be won.

Their job is to ensure that no matter what happens to their homeland, they can deliver an absolute, civilization-ending retaliation from an unknowable coordinate.

The Gundam fights to win a battle. The submarine exists to guarantee no battle is ever worth starting.

The ultimate weapon is the one you never have to use.

It does not need to be flashy. It does not need handsome pilots. It just needs to be perfect.

Itâ€™s a closed ecosystem... that fights the ocean's pressure... just to wait.

The greatest warriors are not the ones who charge into the fire. They are the ones who can endure the silence.

And for ninety days at a time, these sailors live in the deepest, most absolute silence on Planet Earth.
