LA Class Sub Vents Steam From Aft End Of Sail...

[SmokinTep]

Snorkel Juice..............been sprayed/douched with that stuff many a time. Bummer trying to get to the weapons shipping hatch when the brow is aft of the sail.

Also there is a tube about 1/2 way down the aft end of the sail where they vent hydrogen from the oxygen generator.

Heading to Bangor next month with my crew to do a visit on the Jimmy Carter.

I thought that hydrogen from "the bomb" was expelled disolved in auxilliary seawater on the Los Angeles class? Hey, I've never been within a thousand mles of one though (knowingly ).

And, my boat didn't have an O2 generator

Actually there is a diffuser that creates bubbles when under water. When we optest it in port, we have to run tubing from the vent to the water.

Ah, I can see how I misunderstood that now. I wasn't a million miles away. Thanks.

that's exactly what i was referring to... that venting... what is that?

Yeah - may look nice once in a while but we almost broke the record for 33 days of straight rain lately. What color is the sky again? :hmm:

Smokin, Here's a photo I took of the Jimmy Carter heading out from SubBase New London on its way out west last year. I believe that the hull section visible in the background at EB belongs to the USS Hawaii, SSN-776, with, of course, the Barque Eagle in the foreground. Photo taken April 19, 2005.

Nice shot of her.

The "steam" comes from the diesel outboard exhaust valve spray ring. This thing sprays sea water onto the outboard exhaust valve seats to keep them from pitting or warping from the exhaust gas heat.

The hydrogen comes out aft, defused through an aux sea water discharge. The CO2 from the scrubbers also comes out there as well.

Judging from the low waterline, this puppy looks like she's heading for a drydocking.

[SUBMAN1]

Doubt it - that is not a low waterline! It is just the tip of the iceberg.

You must remember that the boat is 86 foot high from keel to mast.

I would think that the normal waterline laps at the lower edge of the missle tube free-flood structure. The boat does seem higher than normal. :hmm:

And don't talk to me as if I was a nub non-qual!

[SUBMAN1]

OK Nub! Just kidding, but I couldn't resist!

Nah - I see these things go past every now and then on their way out of Puget Sound, and I have also toured them a few times - and the height you see is normal. They never get lower than that.

[SUBMAN1]

Scratch that last statement! I should re-word that to say they never get lower than that in Puget Sound!!!
