Ready to put it to one power of time now.

Weapons for you to one I served, then by 21 ice pick submarine bearing 18 to to 900 yards.

The USS Hartford Los Angeles class Nuclear attack Submarine readies to fire fire to one show to one.

In an instant, a two ton, 20 ft long torpedoes speeds towards an enemy submarine alone.

She's gonna get you the target target acquired and destroyed.

All hands stand fast.

Welding operations are in progress.

Hartford is training for its primary mission.

Hunting and killing enemy ships and submarines.

180 ft.

Zero angle.

But these exercises, which CNN was given exclusive access to, are taking place in the harshest C environment in the world.

Coming out from your stop under the Arctic ice chief of the watch on the one m c vertical surface, vertical surface, vertical surface ships, vertical surface, handsome stand fast.

It's an arena where even surfacing requires enormous power and skill.

Five degree up angle to three upper velocity and increasing we were on board is the submarine stocks to the surface with the full force of its 60 tons.

Impact in what way?

We've just broken through 2 ft of Arctic ice.

The North Pole is this way.

Russia is this way in Alaska.

This way, on a mission like this is all about sending a message.

The U.

S.

Navy can operate or wage war if necessary.

In the harshest environment in the world, the Arctic is the newest and most daunting front in the expanding global competition between the U.

S.

And Russia.

These 5.5 million square miles are under an intense battle for dominance as the ice shrinks and opens new oil exploration, new shipping lanes and crucially new paths to wage war were well aware that we're in, Ah, great power competition environment.

And the Arctic is one piece of that great power competition talking principally about Russia.

But also China, Russia and China are two of, uh, two of our great powers that they're trying to catch up with us as fast as they can.

Operating under the Arctic presents unique challenges with no access to GPS Navigation LTD.

Communications and dangers from below and above my skill death time.

07 555 ft ice keels as long as 150 ft extend down from the ice sheet, stationary down of the ship to 10 ft.

Subs like the Hartford are virtually invisible and silent to enemies, allowing them to strike without warning against targets below and above the surface.

These air to of the four torpedo tube.

But you could launch a lot mawr from a sub than torpedoes.

You have 12 vertical launch tubes.

They can launch cruise missiles from those torpedo tubes.

You could also launch unmanned underwater vehicles, drones becoming more of a focus in this Navy and some submarines like this equipped to send out seal team delivery vehicles as well these subs designed to project power in many, many ways, however, Russian and increasingly Chinese submarines air getting better at doing the same.

In luck, Mr I.

Is the Navy becoming mawr reliant on subs as a platform.

We do expect that submarines they're gonna be able to get to places and to conduct action where other units may not be able Teoh right off the bat, we're gonna need the submarine force to kick the door in and other forces to flow behind.
