Steam generator blowdown and PCST are nuc things. TMI for the most part.
Hydrogren overboard dump. Okay, we make our own oxygen underway. You do that by splitting Hydrogen and Oxygen (aka. h20, also known as water, something you have LOTS of access to). When you do that, you let the oxygen inboard and you have to do SOMETHING with all that hydrogen. You let it go right over the side (so to speak).

Sweet five ex-nukes on the forums. Bill, Bubblehead, Henson, and TopTorp, and SubSailor.... hm... who else am I forgetting. Nice know that some opinions are based on RL experience and not internet browsing like my own ...
...though I have read a book or two... http://www.subsim.com/phpBB/viewtopic.php?t=51686 |

I like the touch screens in the Virginia class trainer. |

Wouldn't there still have to be cables connecting non-penetrating masts to whatever gizmo inside the hull that's associated with it? |

quite welcome
Bubblehead wrote: | The equalization system, if I remember correctly, was so that you could open the outer doors after flooding the tube. It was only exposed to sea pressure when the ejection pump door was open. There was not a seperate isolation for it.
As for the 2000# air used. Oh yeah, how could ANYONE forget venting the ram inboard after shooting a weapon. A 688 shooting a torp makes a VERY distictive noise transient as you pointed out to me YEARS ago. |
There are tactical issues associated with the torpedo tube selection. You always shoot the target using an opposite tube. Starbard tubes are used to shoot portside targets; likewise, port tubes are used to shoot starbard targets. Studies have shown that the target is likely to fail detecting the transient associated with a tube fired on the opposite side of the ship. This has everything to do with the fact that the ships aspect exposes the operating noises for that aspect. The transient reduction alone will spell the difference between a target that alerts early and one that fails to alert at all.

. . . only because it was forward of the watertight door |

In a word: yes. Electrical fittings are so numerous they are not worth mentioning. There is a separate hydraulic system associated with sail components. Hydraulic system components are located inboard (AMR) while the hydraulic lines are fitted to the hull. |

EHP's (Electrical Hull Penetrations)
They are NUMEROUS, especially when talking about boats with external tubes (VLS, or flight II 688's)
Working on those can be interesting. Nothing like sitting in a ballast tank and looking through the pressure hull into the people-tank while one is being repaired. We really trust those welders, don't we? |
