Yikes. Those guns are big.

Person is to scale in this picture:

That's awesome!

Ran across this pic last week:

The USS North Carolina is moored as a museum at Wilmington, NC. It's worth the tour if you're in the area. Seeing 16-inch guns in person, and then reading about the rounds they fired (e.g., a 2,700-lb armor-piercing round 21 miles, propelled by 540 lbs of powder) is, well, hard to imagine.

Think about this:

If an Iowa class battleship fired a full broadside it would move the 58,000+ ton ship laterally 100 yards.

That’s awesome!! I wanna hit the button

Yes, and the turrets are on rollers so that if the ship capsizes all the turrets will just slip out, changing the buoyancy...

2000 pound shells...

I visited that ship multiple times as a kid when I lived in NC. Do they still have the alligators in the water around the ship?

Wow. So what does the drill look like that it was attached to?

And the signs saying not to feed them. To which, of course, every kid thinks "Wow! Let's feed them and see what happens!"

Aircraft carriers spoiled naval warfare.
In the good old days, we launched our float planes to spot the dye in shell splashes as we attempted to bracket the opponent and that was it.

And the original full name of the destroyer was "torpedo boat destroyer."

I remember seeing those signs there over 30 years ago. Good times.

It's very interesting exactly how very few times Dreadnought battleships actually fought each other directly.

If memory serves, it's pretty much just Jutland, Mers-el-Kelbir, Denmark Strait, and Surigao Strait.

Most of the other surface actions of WWI and WWII tended more to be centered around smaller ships- battle cruisers, armored cruisers, and down to destroyers & subs.

Tangent:

Really put a nail in the coffin when a bunch of lightly armed and minimally armored destroyer-escorts and escort carriers beat back a surface fleet of capital ships, to include the infamous Yamato....the preeminent battleship ever built.

Kind of like a Boyscout jamboree with .22's fighting against a SS division- and winning.

Then again, I kind of wonder what would have happened if Task Force 34 had been there (as does the world).

I doubt any naval designer nor strategist could plan for the sheer audacity of Cmdr. Evans and the intrepid crews of the USS Johnston, Hoel, Heermann, and the smallest Drednaught- the Samuel B. Roberts. In the words of Drachinifel- many IJN ships sought out a Johnston free environment.

As mentioned by others, yes.

You don't get to see as much as the ship as you did decades ago but still a worthwhile trip

Agreed. As I understand it, the Japanese commander was convinced that the smaller ships wouldn't be attacking unless they were expecting imminent support from heavier units, and that factored heavily in his decision to withdraw. I need to go back and re-read "Last Stand of the Tin Can Sailors" again.

That and they originally misidentified the American ships as Cruisers and Destroyers and started the engagement shooting AP shells, which passed through the American ships without exploding. When they finally switched to HE shells is when American ships started sinking.

For folks passing through the Northern Gulf of Mexico the USS Alabama and Drum are worth a visit.

Gotta wonder if that lateral move was ever used to avoid torpedos, etc . . . Odd use, I know, but gotta use all the tools in the toolbox to prevail!
