Having served on a submarine, I still stay pretty close to the submarine community. Thrilled to hear they’re starting to put magneto hydrodynamic propulsion on our boats. The rumors are the Russians were working on this tech just before the Soviet Union fell and even outfitted one of their Typhoon class ballistic missile submarines with it. Unfortunately that boat was lost at sea during sea trials.

This is a game changer. A boat like this is practically undetectable. Great Leap Forward!

U.S. Navy Submarine First In World Fitted With Silent Caterpillar Drive - Naval News

Submarines use stealth to dominate the seas, presenting an illusive yet deadly threat. Now U.S. Navy submarines will take stealth to a new level. American submarines will now be fitted with magnetohydrodynamic drive.

My father taught me to fish on a river like this (Penobscot River).

I also served on a submarine, but then I decided that I liked the sun and flew airplanes instead.
 
Now that I know what to listen for...
 
I'm still waiting for the rabbits and the recreational vehicle. Maybe @Ted has some pointers?
 
Even our old subs were pretty quiet. In the 1980s, they usually had to augment their acoustic signatures for us (Patrol - P3Cs) to detect and localize them.
 
One ping, and one ping only.

I'm sure Cummins is ****ed about losing the submarine propulsion contract.

I think they’ve been out of it for a long time. What parts did they make?

I think first the navy has to figure out if the juice is worth the squeeze, if it can even be squeezed.
 
I thought the problem today is that subs are too quiet. Now you look for where the noise isn't, because the sub is blocking it.
 
I sacrificed a Bach tape, but it wasn't a good one.
 
You sure it wasn’t Paganini?

Well, it was a cassette, so it's been a while. But I think it was Bach.

Bach is a composer, Paganini is a Tenor.

(yes, I know this is wrong)
 
It wasn't the best I've seen, but I thought this one was pretty well done. It was vague enough in the beginning that you could actually believe it and then added more and more hints along the way to that you were being had.

Another good one was several years ago with the Civil Air Patrol getting old A-10s being retired by the USAF.
 
Damn! I bought it hook, line, and sinker. Even forwarded it to an old submariner I worked with.
<head shake>

It was a joke, e.g. Cummins getting edged out by Caterpillar.

Tough crowd I'm telling you.

Well make sure you go back to him and see if he fell for it too ;)

He fell for it too.
In our defense, such a drive has been discussed for decades in the engineering and physics' applications communities.
 
I got a few younger submarines who inexplicably have never watched Red October. I'm sure they have it on board SOMEONE has to know to watch it.

I have always felt that Down Periscope is a more accurate portrayal of submarine life than Red October.

I don't know a whole lot about submarines, but I'm pretty sure it's impossible for the captain or anyone else alone to even drive it around on the surface, let alone dive it.

I'm pretty sure The Hunt for Red October was not intended to be a realistic documentary about submarines.

But Down Periscope was? :lol:
