The famous submarine converted to snorkel and GUPPY provisions. The hot shot skipper put it through its paces, doing all but loop-the-loops submerged. It was the first GUPPY to be home ported at this base. This picture shows it doing a 60-degree up angle surface off the port of Lahaina, Maui, HI. We often did operations here since the water was shallow enough to allow rescue salvage in case of an accident which put the sub on the bottom. It came up from 300 feet at flank speed and rose high enough to bring the front of the sail out of the water. The skipper was trying to beat the record of the Amberjack(SS522) which had set an official record of 40 degrees on the east coast.

Imagine the tons of water she was pushing to do that. I bet the crew was hanging on for dear life!!!

The crash-down had to be hard on everybody and everything. It would be like watching a whale. Motor shafts and bearings just love that kind of abuse. :doh:

Holy smokes! Im not sure if that is brave or stupid.

Breaching the surface that way in an old boat.....thats guts.

I love watching boats breach the surface this way....

I bet the crew was sick for weeks after that...

That kinda reminds me of a scene from the Hunt for Red October...

BTW, Which boat is that?

I think I'd need to be in the can if my captain pulled a stunt like that! :rotfl:

That Forward Torpedo Room had better not have had any of their torpedoes even the slightest bit loose. They might have been the first submarine to be able to shift torpedoes forward to aft after such nonsense. I wonder what the impact felt like when it hit the water. Better not have any loose fillings
Even so, it does look cool.

Like a lot of these type of "stunts" it looks a lot cooler from the outside than it does from the inside.

Nice pic:up:

Imagine back to WW2 if some poor fishermen in a Sampan saw this coming out of the water like this.:o

I read somewhere (dont remember where), that when coming to battle surface, the sub would angle its planes downward, increase speed, and then blow its tanks dry unti it couldnt maintain depth anymore, then put the planes on rise and come up. I think this source said the requried crews would come out of the forward and stern hatches on the deck, and could get the first shot off (from "at ready" storage on deck somewhere) with the deck gun in about 15 seconds once surfaced.

O'Kane writes about his battle surface technique that he brought from Wahoo to Tang in his book Clear the Bridge.
Everyone gathered at their stations for the ammo train, and the on deck crew at the hatches and gun access trunks. Negative and main ballast was blown and the boat was held down with the planes. The planes were shifted and the boat "popped to the surface like a cork". Would be really cool to be able to recreate in game.
I think there would have been a foul odor emitted from any sampan crewman so confronted.
I believe that the boat in question in the picture was the USS Permit.

That picture is reputed to be of the USS Chopper which underwnet an excessive angle with an emergency surface and came close to sinking

Here's the deep dive report

http://www.usschopper.com/Chopper Deep Dive Report.htm (http://www.usschopper.com/Chopper%20Deep%20Dive%20Report.htm)

Here was my comment on this tpe of surfacing on another forumThis looks like a super rollercoaster ride from the outside, so most people think it's really cool.

What they don't tell you in most of these is that such angles are dangerous because if the boat doesn't settle properly, she'll sink with little or no chance of recovery.

There's an angle called the "critical angle" at which the air starts to bubble out of the ballast tanks and water starts to flow back in.

At this point it's a race between the exchange rate and how fast you surface. If the boat loses momentum and doesn't break the surface high enough to flatten out, it will slip back into the water with little or no chance of recovery. There's usually only enough hi pressure air for ONE complete blow of the ballast tanks. Then you have to pray the LP blower can keep up with the exchange rate while you try to reduce your angle as you slip deeper.

When you break the surface like this, all the air in the forward group equalizes to atmospheric, so if you slip deep enough, you start taking on water again, and if you're past critical angle the LP ballast blow may not keep up with the inrush of water into the forward group.

One thing on the Chopper's side was the after group was not already blown until the last few seconds and this gave her the ability to recover when she slipped below the surface after breaking at such a steep angle.

Different navies have almost lost boats because of this. It's not fun being at such a steep angle hoping you'll surface correctly, especially in deep water. Thankfully the Chopper survived a 1000ft depth excursion with a hull never designed to go that deep.

When this happens the old saying of there's no atheists in foxholes applies . . . at this point almost everyone on the boat starts to pray for the boat to recover, some silently, some out loud. And when she does they all whisper a thanks to the man upstairs and the people who built her.

Sorry for being a wet blanket, but "been there done that", never wanted to try it again.

That is a seriously awesome pic! The comment about damaging the boat triggered some info in my brian... one of the late war US battleships (can't remember which, if not Mighty Mo, then a relative) attempted an emergency stop from full speed. The ship stopped dead inside its own length by stopping the screws and closing the rudders (port rudder turned max starboard, starboard rudder turned max port)... the water version of an airbrake. When she went in for refit, they found the rudders were loose in their bearings...

Imagine that captain behind the wheel in a car on a dirt road. Now i know why modern subs can't go faster than 40km, its not that they can't the navy have made sure they never will!!!! :lol:

I can only echo the fine line between training and disaster when performing emergency maneuvers. I have seen on modern nuclear boats emergency blows that resulted in dives much deeper than anticipated to emergency rudder failure drills at high speed that also had wen dangerously close to resulting in disaster. Submarine commanders undertake such drills with intense preparation and only perform them enough to be sure that the first time their crew sees the boat react in this manner isn't when they really do have an emergency with potential major equipment failure.

I spent several years manning the sternplanes during battle stations when many of these "angles and dangles" were performed. While I took great pride in the trust placed in asking me to sit there, I dreaded those events. It was my time to shine but I always knew in the back of my mind that all I could do is react to what the boat was doing. There was always a probability that that simply wasn't good enough. You don't drive a 7000 ton hunk of steel at 40mph. You just nudge it.
