Thanks Chris:) Geeze... HMS Gotland outside San Diego as a surface vessel. https://en.wikipedia.org/wiki/HSwMS_Gotland_(1995)#Lease_to_the_United_States_Navy In 2004, the Swedish government received a request from the United States of America to lease Gotland – Swedish-flagged, commanded and manned, for a duration one year for use in anti-submarine warfare exercises. The Swedish government granted this request in October 2004, with both navies signing a memorandum of understanding on 21 March 2005 From the Russian Navy website: Russian Nuclear Subs' Entry Into Service Pushed Back to 2014 http://rusnavy.com/news/navy/index.php?ELEMENT_ID=17082 |

I could nosh on one, I'm hungry. Subs are quite tasty. And a beer with it is nice. Oh Nosh means Cheers in Kurdish:) http://blogs.wsj.com/middleeast/2013/09/13/nosh-the-peculiar-case-of-kurdish-beer/ Say hello to our Kurdish beer: Ava Zêr! Biji Kurdistan:) |

Anyone heard about the new U 36. A fuel cell submarine With each crime and every kindness we birth our future. |

Yummie. Perhaps a Whiskey on the Rocks as an Apéritif:) |

Anyone heard about the new U 36. We haven't heard any of theme because they are so silent:) Anyway here are them. Lonely Wolf. http://www.fuelcelltoday.com/news-archive/2013/may/u36-another-fuel-cell-submarine-for-the-german-navy |

Anyone heard about the new U 36. What i found very interesting is, this submarine is fully operational at 2000 feet. Not diving tho but operational. My youngest was invited a few years ago. With each crime and every kindness we birth our future. |

Design depth is the nominal depth listed in the submarine's specifications. From it the designers calculate the thickness of the hull metal, the boat's displacement, and many other related factors. Since the designers incorporate margins of error in their calculations, crush depth of an actual vessel should be slightly deeper than its design depth. Correct, and for submarines of the class 212A U36 is the latest its 700 meter. https://en.wikipedia.org/wiki/Type_212_submarine With each crime and every kindness we birth our future. |

In one sense I'm not surprised that the Germans are producing a large deep diving submarine, as, for many years they led the world in the field of submarine design and construction Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

They usually operate not far from shorelines unless they have ICBMs. They dont launch ICBMs from any deep depths at all. But that means nuclear war. The deepest-diving large, military-style submarine was the Soviet submarine K-278 Komsomolets, with a hull made of titanium, making it very expensive, but able to withstand significantly deeper dives than the best submarines made of high-grade steel, like American nuclear submarines. The Komsomolets was a nuclear powered submarine specially designed to make trips as far down as 1300 meters (4265 feet) below sea level, definitely less than the Trieste, but very significant because the Komsomolets had to "defend" a much larger air bubble against the encroaching pressure of the surrounding ocean. |

Air-Independent Propulsion systems are making non-nuclear submarines very hard to detect. They don't have the range or speed of nuclear subs, but could wreak havoc in coastal waters. There is an on-going discussion in the US submarine community about the usefulness of non-nuclear boats for coastal defense. Donald Infernal Optimist / Submariner, retired |

Yes but do subs need to dive that deep? Not necessarily so. Submarines DO operate in the open ocean, and being able to go deep can be useful in avoiding detection by the enemy, or perhaps avoiding torpedoes fired at the boat. And our Fast Attack subs participate in Oceanographic Research, both in the deep oceans and in the north polar region. When I rode the FBM boats, we spent very little time at shallow depth. We were ALWAYS in communications with our Command Authority. Yes, we came shallow to launch, and to do routine radio comms and draw fresh air, but mostly we ran deep and quiet, and prayed that the "End of the World" message never came.

Yes but do subs need to dive that deep? Here in Europe most countries are surounded by shallow waters. I think the average depth is about 60 meters in the Baltic Sea. 400 meters in Landsort south of Stockholm. Then we have the North Sea, Skagerac and Kattegatt that's almost the same. The Mediterrainian Sea and the Black Sea is not deep either. |

Here in Europe most countries are surounded by shallow waters. Germany also sells their subs, or their designs, to other countries that do have deep waters to patrol. Donald Infernal Optimist / Submariner, retired |

Here in Europe most countries are surounded by shallow waters. Both Germany and Sweden makes subs. The Swedish manufacturer Kockums was part of ThyssenKrupp Marine Systems in Germany. But on 22 July 2014 it was announced that Saab had bought Kockums from Thyssen Krupp. The new name will be Saab Kockums. If ThyssenKrupp Marine Systems are making the subs in Germany you mention I don't know. Next generation of swedish subs. The new submarine project is intended to be an improved version of the Gotland class. http://www.defenseindustrydaily.com/saab-story-swedens-new-submarines-024760/ Both The Royal Australian Navy and the Royal Netherlands Navy are intressered. |

I was thinking of trying out subs' but I can only hold my breath for about four minutes at a time..... |
