As someone that know as much about submarine designs as rocket design, one has to wonder how no one noticed the error. Since it was never launched, and it be fixed or is it just going to be scrap?

70 tons is 140,000 pounds of "extra" weight. What did they do, make it armor plated? If the skin too thick? I am just glad it is not my tax dollars for once that were wasted.

Make the weight match the displacement to achieve neutral buoyancy.
Loose the weight or increase the displacement by around 2300 cu. ft.
Larger ballast tanks would do it, think gurney bulge

Heck, they could just stretch it a little like they do with them limo-zeens.

Larger ballast tanks would not do it. They would have to increase the displacement of the hull, ballast tanks do not do that. The entire interior could be ballast tanks, if the hull ways more than the water it displaces it is only going down.

They needed some of those women from that movie, Hidden Figures.

Or maybe just my 9th grade science teacher.

Can that even be done? A ship has a keel, right? Once the keel has been laid (and I presume construction has gotten that far, already), can a ship be modular enough that you can just splice in another x amount of hull (and keel) to increase its displacement? The article mentioned adding length to the vessel, but I'm sure it's not as Lego-simple as that.

I was thinking external ballast tanks, like the ole torpedo bulges from dubya dubya II which I kinda referenced via the gurney bubble thing.
But I Didn't quite write what I was thinking.

Dunno. Mongo only pawn ... in game of life.

I've never built a submarine but I figure there's nothing simple about it at all no matter what yer doing.
A guy who used to work for me served on the Dallas in the reactor room, he told me that the difference betwixt a hunter/killer and a boomer is that they cut the middle of the HK and splice in a bunch of missile silos to create a boomer.
prolly a little more to that too.


But like dad said in his memoirs .......

Just checked, the interwebs says no keel so it would be easy-peasy.
They couldn't put it on the internet it it weren't true.

Hope this ain't top secret ....

Looks like they build em in pieces








I think this one is on the take-apart and not the go-together:

They are built a lot like airplanes, and I don't think it would be a huge feat to add hull sections. obviously easier in the design stage lol.
Sammy, I missed your part about gurney bulge or I likely would have understood what you meant.
As to similarities, they do not just stick in a missile section. The goal of a hunter killer and a boomer are very different, and thus so is the design in many ways. The Los Angeles class hunter has a beam of 33 feet, the Ohio class boomer is 42.

Dude, just slice down the middle and add in 9 feet of hull. Done.

Don't forget the Flex Seal as a final layer of protection over the duct tape
