I thought every sub just has attack dolphins they fire out of the torpedo tubes?

The dolphins only decided to swim with the sub after determining they couldn't have sex with it.

Guess the sonar was off, then, huh?

And how do we know these aren't Russkie dolphins?

A Russkie dolphin don't take a dump without a plan, son.

A billion dollar boat, and as soon as flipper shows up, I didn't look at the boat again. Nature is always greater than man-made.

Good find subby.  The symbolism there is kind of epic, since every qualified submariner wears a pair of (heraldic) dolphins on their Submarine Warfare badge.

Cool!  Just looked that up.

I wonder how fast the sub was going. It was amazing that the dolphins were cruising right along with the
boat.

Their sonar used more than 1 ping?

I wonder how many bridges we could have repaired for the cost of that sub?  Oh, sorry....I mean USA! USA! USA!

Relax about the bridge thing for a few.

The one that collapsed in Seattle yesterday was because of an oversized truck load clipping the top of the truss, and nobody died.

A quick google shows the top speed of a dolphin at about 22 mph.  (I'm surprised they are that slow- apparently much above that speed their tails begin to cavitate.  Orcas can hit 35 since they are bigger)  Max surfaced speed of a Virginia class is 25 knots, or about 28 mph, and I'm sure they weren't going anywhere near flat out on that run, so dolphins were probably just cruising.

Submerged speed of a Virginia is "Greater than 32 knots"  My guess is quite a bit greater, at the cost of being noisier than hell past a certain speed.

They are riding the bow wave, it's pushing them along just like a surfer riding a wave.

Why do we need more submarines?

Because our government has to much money. That's also why they give so much to foreign coontries that stab us in the back.

I'm sure I'm wrong about this, but going through the water like that seems terribly inefficient. Or is that the highest the sub can stick out of the water?

You are wrong about that.

Subs like that generally only cruise on the surface when they are approaching or leaving port - there's no point in making them efficient for surface cruising.  Plus a cylindrical hull shape isn't exactly great for roll stability.

Subs are designed to go faster submerged. Pretty cool

Probably around 10 knots. That's about as fast as it is safe with people in the conning tower. Dolphins love racing subs. I remember a couple of times coming out of San Diego where they would circle around ahead of the bow, then loop back and jump the hull behind the conning tower. Even cooler is when you are submerging and can watch them through the periscope, before you bring it in.

That was farking awesome.....

Dolphins love to surf the bow wave. I've seen it many times while standing on the too of the sail.

Yup.  That's got to be some serious good omen type stuff for a submariner.

I wonder how many Chinese Naval intelligence grunts have been replaying that video hoping to divine some new secret design element to copy for their subs?

The PR flacks for Northrop Grumman must have achieved orgasm seeing dolphins show up for the filming of their $2.5 billion submarine.

Argue and derp all you guys want, but I loves me some submarines AND dolphins. If I was on that conning  tower and saw that, I'd have a grin on my face for the rest of the deployment.

As cool as this video is, some pedantic prick should point out that the Submarine Warfare dolphins are actually dolphinfish.

I think that stuff, too (been playing too much Far Cry 3:  Blood Dragon) for too long.

Modern submarines are not made to go at their top speed on the surface. In addition the dolphins show up because they like to play in the huge bow wave being pushed ahead of the boat (which is why they are slower on the surface than they are submerged), and when I say huge I mean huge, like if seen from the surface it hides most of the boat from view huge. Easily 1.5 times the distance from the waterline to the front of the sail tall and twice as wide as the beam of the boat at ahead flank speeds. It takes a lot of SHP to push that mountain of water around.

jigger: I'm sure I'm wrong about this, but going through the water like that seems terribly inefficient. Or is that the highest the sub can stick out of the water?


It is and it depends. Obviously there's a maximum height but that depends upon the class of boat.

pudding7: Yup. That's got to be some serious good omen type stuff for a submariner.


Actually it's quite common when a high speed surface transit lasts more than an hour or so, sometimes less in warmer waters like off of Florida's Port Canaveral where there are more dolphins swimming around.
