UFO moves at hundreds of miles an hour - underwater


Unusual Tournament

Sounds like a supercavitating system.  Russia had the first one on a torpedo called the Shkval.  It had spotty accuracy and limited range but could travel at around 200 knots.

I don't mean to sound like the annoying nerdy kid that reminds the teacher that he/she forgot to assign the class homework. But this craft should be called a USO -- Unidentified Submerged Object. No matter what you call it, anything able to cut through the water and go that fast is quite impressive.

Yes I agree. It’s extremely impressive, a level of underwater performance far beyond any human capability.

Invisible Residents by Ivan Sanderson is an interesting read.

But they’re not aliens, right?  That’s the point.  They’ve always been here.  They are from here.

Probably another case of swamp gas or a weather balloon of course!...Oh, wait?

Jupiter.  Or anything, really, so long as the questions stop this instant and the authority on related subject matter on which I depend for my livelihood is not threatened.

Yes, the article I read on it, could go the length of a football field in 1 second!! impressive. they called it an underwater missile.

you very well *could be* correct and I do agree with you, but it's far from proven. But we do not share the same DNA, for sure.

@and-then called it.  

A supercavitating system is a system that uses a vapor cavity to reduce drag and allow objects to move at high speeds underwater. This system is used in torpedoes, propellers, and other underwater vehicles. 
 
How it works
  • When an object moves through water at high speeds, the pressure drops behind it 
     
  • If the pressure drops below the water's vapor pressure, bubbles form 
     
  • The bubbles create a cavity that surrounds the object, reducing drag 
     
  • The only part of the object in contact with the water is the cavitator, which is located at the front of the object 
     
Applications
  • Torpedoes: Supercavitating torpedoes are capable of remarkable submerged speeds 
     
  • Propellers: Supercavitating propellers can reduce skin friction drag 
     
  • Underwater vessels: In theory, the technique could be extended to an entire underwater vessel

You would think an Admiral would know about supercavitating systems and it wouldn't be a big deal to them...why tell a congressman?  BS

don't ya just love sarcasm... This strange individual will probably think I'm serious. Wouldn't be the first time.

When over the years I've replied with IMO bleeding obvious sarcasm- I'll get PMs saying I'm glad & happy I've changed your mind.. This is how fekin stupid some humans can be!!!

Personally I find it fascinating 😉

Yep one of the first books about USOs, one other writer was seriously interested in this matter : Preston Denett

Cant say if there are hard proofs of this around here as only militaries or sosus from different countries could give serious infos on this, but nevertheless i find this subject fascinating

Well thank you, Mr Dajarma, for tagging all us humans with the same brush. For decades humanity has waited for answers about our place in the cosmo and little did we know you are the intergalactic messiah. Truly you have no equal on this planet 🪐

I like to think I have a good collection of books on the subject, but don't have anything by Preston Denett; will look into him.

Thanks, but I dont drink.

You can hook me up with a cheeseburger and a medium fries though.

Make it snappy and then maybe you can keep the change.😄

UT works the late afternoon shift. At least that's what I can discern from his posting habits.
