I’ve always wondered: Why can’t ships go faster? Is it simply friction and surface tension? I guess so. Those cigarette racers go fast as blazes and scarcely touch the surface as they reach top speed. How fast can a submarine go? Has anyone successfully used cavitation on ocean-going vessels?
The Navy's Stealth Destroyer Has Fired A Missile For The First Time
After over $26B spent on the program, the launch serves as a glimmer of hope that the tiny Zumwalt class may one day live up to its potential.

BTW you do know that Forbes is owned by the Chinese?
they have guns that dont have much range, shells that cost half as much as a missile Each, a bow design that is unstable in heavy seas, engines that are very unreliable and a lot less fire power than a CG, but about the same size. Scrape the damn thing.
We could tell you, but we really would have to kill you...
What a Charlie Foxtrot.
Why build even a single one?
Prior to retirement, I worked on this disaster of a program. I believe that the only reason it survives is because of the political pull that Lockheed-Martin has.
No. It's wavemaking - of surface waves. The reason that cigarret racers can go fast is that they plane on the surface of the water thus putting much less energy into wavemaking.
Because submerged submarines are submerged they don't make surface waves and so they can go faster for the same horsepower. On the surface most subs are limited to speeds less than 15 knots because of surface wave making again. The shape is horrible for that purpose
The superstructure looks like a casemate ironclad.
Because the cost to cancel the contract was the same as the cost of building 3 of them.
If you were told, you wouldn't believe it.
Hull speed is dependent on the amount of water it displaces and how fast a wave can move through that much water.
Animagraffs calls this thing a “deestroyer.”
If they can’t spell, should one wonder about the accuracy of the rest of the info?
I know some folks here will call me a grammar Nazi, but I’m becoming convinced that we are living in Idiocracy.
I seem to remember some crazy stuff going on with the guns for this Destroyer.
Why not?
Mo’ Nature makes a pretty impressive design:

Displacement vessels (ships, sailboats) are limited in speed by the length of their water line. Planing vessels (speed boats, catamarans) are not.
One reason Germany lost WW 2 is that they were obsessed with making complicated, high-tech devices while everyone else was making reliable, lower-tech devices.
Just sayin’.
‘Hull speed is dependent on the amount of water it displaces and how fast a wave can move through that much water.”
‘Hull Speed’ is determined by water-line length. Hull speed or displacement speed is the speed at which the wavelength of a vessel’s bow wave is equal to the waterline length of the vessel.
