How deep do you think military subs can go these days?
I was reading about some Russian subs using titanium hulls for extra pressure resistance (can dive deeper) and started thinking "I wonder what's going on these days?". I get that the real numbers are classified...it's just damn fascinating and fun to wonder about. |

I was reading about some Russian subs using titanium hulls for extra pressure resistance (can dive deeper) and started thinking "I wonder what's going on these days?". I get that the real numbers are classified...it's just damn fascinating and fun to wonder about. I bought a book a couple years ago that challenges the widely accepted fact that the Alphas could dive to extreme depths. I'll have to find it, the book was published somewhat recently compared to every other submarine book I have. Cold war submarine design or something like that, absolutely fantastic book. I would guess it is well over 1000 feet for our modern subs. Any more though, it's more about how shallow you can get while still being able to maneuver w/o broaching or running aground. |
| Those were the 7 Alpha Class boats (all decomissioned) that had a reported diving depth of 800m and the one Mike Class (laying at the bottom of the Norwegian Sea) that successfully made it to 1,020m prior to the accident that sunk her. The Virginia Class boats can dive greater than 240m but if we're not pushing our strategic assets to go deeper then my guess is there isn't a need to do so. The Navy gave DSV Sea Cliff (their deepest diving submersible) to Woods Hole Oceanographic Institute well over a decade ago. And it was purely a research vehicle. |

Titanium is highly resistant to saltwater corrosion; but, when the Alfa surfaces, all that nasty oxygen rusts the fuck out of it. It's stronger than aluminum, but weaker than steel, so I'd say Keptin Kamerad and the Pink November sub of tactical attacking may survive 20,000 leagues under the sea, but not below 1,000 feet.
On the other hand, our Ohio and Los Angeles class subs have journeyed to the center of the Earth, been shrunk to perform precise torpedo strikes on cancer cells in human bodies, and been to the Moon. There used to be Nazis in a secret base in Antarctica, but then the USS Nautilus paid them a visit. Tovarisch. |

The answer is pretty damn deep, and classified.
Some mentioned the Alfas, but iirc those couldn't do deep dives outside of emergencies, something about damaging the hull or fittings. The only Mike class and the few Sierra class boats are supposed to be very deep diving though. |

This Balao Class submarine exceeded its design depth by quite a bit and it's a hell of a story.
The bow achieved a depth of 1000 feet. http://jalopnik.com/inside-the-absolutely-wild-ride-of-the-uss-chopper-1587554224 |

The Haunebu saucers would have never kept enough air in their hulls to reach the Moon. That was misdirection from the Nazis and they actually landed in The Land That Time Forgot. |

Titanium doesn't rust. From Wiki take it for what you will: "Like aluminium and magnesium metal surfaces, titanium metal and its alloys oxidize immediately upon exposure to air. Titanium readily reacts with oxygen at 1,200 °C (2,190 °F) in air, and at 610 °C (1,130 °F) in pure oxygen, forming titanium dioxide.  It is, however, slow to react with water and air, as it forms a passive and oxide coating that protects the bulk metal from further oxidation"
and "It is highly resistant to corrosion in sea water, aqua regia and chlorine." and "It is paramagnetic and has fairly low electrical and thermal conductivity." I do see benefits of a titanium hull, but don't see deep sea Sons of the Motherland Conquer Godly West depth capability. |

Here is your answer
Our Boats can go Deeper than 400 feet and faster than 20Kts. yes the Alfa's could go to 4000 feet. That is why we made the MK48 ADACP. Now the Alfa's can not go past the surface. Their solid metal Reactors are all solid, so they are not going anywhere. Also the once the Alfa' s went as deep as they could go they were never allowed to go that deep anymore due to stress fractures in the hull. |

Did you know I have to big on more water (weight/ Ballast) to keep the submarine at deep depths than I have to at Periscope Depth. And at 150 feet I have less water onboard tan Periscope depth.
There is really no reason to make our submarines go super deep. Once the sub is under the Layer it is very hard to fine. How may surface sailors have every tracked one of our submarines..... That did not have its Noise Augmatator turn on full blast? And also was not restricted a 5 by 5 mile box? Or banging on the hull every 5 mins with a hammer. "TMOW (Torpedoman of the watch) go load 2 Green combos in the 3" launcher" Reason why is because that stupid Helo can not find us. We will use the pyros to help him out. Yes these are the thing we do to make the Surface navy feel good about themselves tracking submarines.
