Navy hulls and personnel are tripling.

That's quite a lot.

And then naval hulls are gonna double in the next year.

That's a lot of ships and a lot of people in the Navy.

Here's some more fun statistics.

So if you look in 1941 and go over,

That's a bumper year for U-boat construction, 1941.

Going to 1942, really ugly if you're a merchant-ran crew member because it's double the number of tonnage of merchant ships that are being sunk.

But then keep moving over.

Look at merchant hull construction, up by four times.

And the next year, that's going to double.

And oh, let's look over for 1943.

Look how many U-boats are being sunk.

It goes way up with all those new technologies that I've just told you about.

So even though the Germans produce a lot more U-boats, the kill rate is so high that there's hardly any net gain.

And then here's some more fun ways of looking at it.

So you look at new ships, as soon as the United States gets in the war, new ship rates go up, up and away.

But the losses are really high through mid-1943.

And then it's in mid-1943 that you can see the big divergence between construction and what's being destroyed.

And the Germans just can't keep up with this.
