Submarines

Submarines are naval craft that can operate for an extended period of time underwater. They are used primarily as warships, as well as for business, scientific and other purposes. Submarines are different from submersibles, which only have limited underwater capability.

Why do submarines are in torpedo shapes?

That is the most efficient shape for fast, silent, speed underwater.

What is the total weight of a Virginia class submarine?

7,800 tons submerged displacement, not counting full stores load and weapons loadout.

Who controls access to the topside of a moored submarine?

The topside watch will be charged with the comings and goings on the topside of the submarine (called a boat by those who sail on them) when the boat is tied to a pier or tender. There may be an officer of the deck there on some occasions, but when the boat is lying along side a tender or the dock of a submarine or naval base, security is such that the topside watch will be the lone crew member on the deck.

What class of submarine was Kursk?

The Kursk was an Oscar II class submarine, of the Russian Navy.

What is a crazy Ivan?

A "Crazy Ivan" is US Navy slang for a sudden, extreme turn by a submerged submarine.

It was used to mean what a Soviet submarine captain did during the Cold War when he wanted to check if an American sub was following him. He would turn all the way in a circle (to port or starboard), using his sonar to check for the supposed "stalker" (American sub). Then he would go back to his regular course (if he didn't find them). This slang was explained in the 1990 action movie "The Hunt for Red October" based on the 1984 novel by Tom Clancy.

A fun little tidbit for you: "Ivan" means "John" in Russian, so it's actually a "Crazy John".

What does EMC SS mean in the Navy?

Electrician Master Chief (SS)

(SS) indicates the individual completed a qualification process on submarine systems.

What is a submarines buoyancy?

A submarine has a variable buoyancy due to it's ballast tanks. When a submarine submerges, it fills it's ballast tanks with water which causes negative buoyancy. When a submarine surfaces, it pumps the water out of the ballast tanks thus giving it positive buoyancy.

What is the qualification requirement for serving on board nuclear submarines as officer?

The basic requirements for serving aboard a Nuclear Submarine, be it as an enlisted sailor or commissioned officer, are pretty straightforward:

  1. Citizenship - Must be a U.S. Citizen (No Foreign Nationals).
  2. Volunteer for Hazardous Duty - Must be a Volunteer for Submarine Duty (serving aboard a submarine is considered Hazardous Duty for pay / promotion purposes).
  3. Security Clearance - Must pass a Background Investigation and be granted a minimumSecret security clearance (Top Secret for Officers and key Enlisted personnel).
  4. Advanced Health Screening - Must pass Health (including pressure testing) and Psychological Evaluations, which are well beyond Navy entrance screening standards.
  5. Nuclear PRP - Must be granted acceptance to, and maintain status in, the Nuclear Personnel Reliability Program (Officers, Corpsmen, & Key Weapons Handling Personnel).
  6. Submarine Warfare Qualification - Like all Submariners, must Qualify in Submarines. There are no exceptions; if you don't qualify, you're history.

Though submarine duty has an almost romantic attraction, and those of us who've served aboard them (most of us anyway) wouldn't trade the experience for anything, duty aboard a nuclear submarine takes its toll in some way on just about everyone, either in health, family, or career. It's easy to be attracted to, and want something when you don't know all the facts, and of course they won't tell you all the facts before you volunteer, primarily due to the fact that it's classified, and if they did, they'd have a lot fewer applicants.

That's the easy part.

Here are a few unclassified facts:

1. Submarine duty is rewarding, but it's also a high-stress, high-pressure, no mistake job, particularly for Officers. I have personally seen Officer careers ended by making a single clerical mistake regarding the nuclear propulsion systems. There is absolutely no room for error onboard any nuclear vessel, and the Navy has a strict zero-tolerance policy for anyone who screws up in the propulsion spaces.

Unrestricted Line officers who volunteer for submarine duty typically do so for the added challenge, prestige, and engineering experience. Those that make it far enough in their careers to actually command a boat usually haven't made any mistakes (though I'm sad to say these days there are more than a few idiots who shouldn't be allowed to command an RC submarine in a backyard wading pool).

2. Divorce rates are typically higher, around 70-75%, since unlike ships, submarines do not transmit any communication while at sea unless it's a severe emergency or they are specifically ordered to. Coupled with the fact that you can't talk about anything you work on because it's classified, any mission you go on, where you're going, where you've been, etc., makes it extremely difficult for the average family to deal with.

Wives literally have to take care of everything while you're at sea - bills, banking, car/home repairs, kids, pets, emergencies (e.g., fire, flooding, accidents, medical, etc.) and all without the support of a husband they can talk to every night or help them with. Extended family usually helps, but most women who marry submariners don't fully understand what's involved, and not everyone will be stationed in a port near their families. There is of course a Navy support system in place to help dependents, and it's gotten better over the years, but it's no substitute for a spouse. Even then, remember the increased stress the sailor is already under to begin with.

To give you an idea of how much separation time I'm referring to, during my first year aboard, I calculated that we were either at sea or away from home port a total of 293 days. That was about average the rest of my time onboard as well. For the first 5 years I was married, I estimate I only spent a total of 1 or 2 years of time with my wife, probably less.

During the time you're actually in port at home, you're still on a 4 day watch schedule, meaning that every 4 days you get to spend 24 hrs on the boat while the other 2/3 of the crew gets to go home. Your only function in port if not training is to ready the boat to get underway again.

For those that think the "steady schedule" of Ballistic Missile submarines is more conducive to family life than serving on a Fast-Attack, think again; the divorce rates are actually higher for Boomer sailors. That's because wives know that their husbands are going to be at sea for a specified period of time, and can get away with cheating on them without much fear of being discovered. The sailor's term for them is "Boomer Widow".

We've been married now for over 32 years, but we're the exception; of everyone I served with, we are the only ones who are still together, and that's largely due to the fact that she was a sailor too when we married, so it was much easier for her to deal with. Everyone else is on at least their 2nd or 3rd spouse, or just gave up dealing with long-term relationships.

In the end though, I chose to leave after 8 years (5 years of that was Sea Duty), as it got real tough coming home from sea and having my daughter run to the other side of the living room because she didn't know who I was.

Forget anniversaries, holidays, birthdays, and anything else you're used to in life - even 25 years later, they come and go and I've never really regained any appreciation for them. Like they are at sea, they're just another day on the calendar.

3. Health - Even though submarine air is purified mechanically and chemically, submarine environments are hardly clean. Aside from the host of carcinogenic agents used onboard, there's diesel fumes (my first year I slept directly above the Diesel-Generator room), and a host of other lovely things that can hurt or kill you. That's why it's all-volunteer, and it's considered hazardous duty. Radiation is typically the least of your worries.

To give you an idea of how bad the air can be, the ship's brass plaque is typically mounted outside the Commanding Officer's stateroom. After polishing to a bright luster with Brasso, it only takes about 2 weeks for it to re-tarnish itself due to the atmosphere.

Altered sleep patterns are common among most submariners, myself included, even so many years later. The constant changing of time schedules affects the body in ways you can't appreciate until you've experienced it. For example, we used to leave port on Romeo time (Eastern Standard or Daylight time), then switch to Zulu Time (GMT) after clearing the harbor. After the Maneuvering Watch (watch stations for entering/exiting port) is secured, the boat goes into an 18 hour watch rotation, meaning you're on watch for 6 hours, then off for 12. That's of course unless you're short-handed, and are in a 12 hr on/12 hr off watch rotation (Port/Starboard watch rotation). It doesn't take long at sea to lose track of time, and the only real way you know what time of day it is, is by the meal they're serving.

After all that for a few weeks or months, you come home, and switch back to Romeo time again.

Forget sunlight also, unless you see it in a DVD, video, or the Periscope.

I lost 2 friends to suicide and more than one to accidents or illness that resulted in their disqualification from submarine duty or medical discharge. I myself developed asthma at the height of my career, disqualifying me from submarine duty and effectively ending my Navy career. Most of my back problems are also directly related to my boat time (lots of heavy lifting), and 3 spinal operations later, it's a constant reminder of what it cost me.

It wasn't as big a deal for me - I always knew I could make it in the civilian job market, and I did pretty good after I was discharged. But Officers typically plan for a long career, and the slightest problem can end those plans. The Navy doesn't publish such statistics, but the rate of deaths or disqualifications is higher than they admit. Still, Officers who have successful tours aboard a nuclear submarine typically do pretty well after they leave the service. Those that are screw-ups are a different story.

Aside from the regular aspects of submarine duty that affect crew, it's particularly tougher for submarine Officers, since virtually all Officers (except the Navigator and Supply Officer), if they want a submarine command of their own, must qualify as an Engineer before that's even a possibility. Submarine Officers are typically pushed toward Engineering anyway, as that's just the nature of serving aboard a nuclear boat.

Add to that the normal Officer qualification and evaluation requirements that are just part of being a Naval Officer, and it makes the job that much more stressful.

Having said all that, I still wouldn't trade my experiences for anything in the world. I did and saw things in several years that people can only dream about. Is it hazardous and dangerous? You're damned right it is, and don't think for one minute the risks aren't that big. But it's also one of the most rewarding and fulfilling jobs in the Navy. Submariners are picked from the top of the Navy's sailors, and if you want to work with the best, there is no better place to go. The Submarine Force constitutes only about 2% of the Navy, and volunteers go through a rigorous screening process.

My point is that if you do decide to volunteer, do so with the full knowledge of what it could cost you later in life in terms of health and/or family. I had no illusions about submarine duty before volunteering, either with health or family; my wife and I almost didn't get married because of our differing opinions about what my career path should've been (obviously we worked it out).

Even with the problems I have now, I have no regrets. But it's not for everyone; I've found that to really motivate me and perform well, I need a high-stress, high pressure environment to work in, and submarine duty gave me that. After leaving the Navy, the only thing I found comparable was working in the Space Program, on both manned flight & unmanned satellite programs.

Most submariners are the same way, thriving in such environments. However, not everyone is cut out to exist in tight quarters for long periods, working extremely long hours (caffeine will become a necessity of life), and be under constant pressure to get everything you do right. If you're such a person, or want to discover whether or not you are that kind of person, then it's worth the risk. But don't volunteer with romantic illusions of the type of submarine duty seen in movies, as real submarine life is a far cry from fictional portrayals. The work is hard, the hours are long, and the sacrifices are many. In the end, each individual will need to determine whether or not the rewards were worth the sacrifices.

Do modern submarines have an artificial horizon on the steermans board?

No - in the 70's, there was a monitor system called the Conalog System, which sensed the boat's movement, depth, bubble and course and displayed it on a monitor that sat in front of the planesman and gave him a 3D line display that appeared to move toward him, or in the direction he was steering. It was eventually replaced with standard gauges (depth, rudder, bubble, etc.) because it tended to cause the planesman to become somewhat fixated on the display, even to the point it would cause them much difficulty in staying awake. "Hypnotize" and "Trance" aren't really accurate, but they're pretty close as to what was occurring.

The newer class submarines may use electronic display systems for steering, but if they do, they're classified. Any electronic display would likely be an electronic repeater of a mechanical input anyway, since the Navy typically doesn't go back to a system that they've trashed previously because of problems without good reason to believe it won't happen again. Critical systems tend to be mechanical in nature (even if they're just backups), since most major casualties will usually result in an electrical failure or emergency shutdown of a Main Electrical Bus, which could render any electronics useless.

Having gauges to look at might seem boring, but in reality they keep you more alert. It takes skill to maintain proper bubble, course and depth while submerged, and keeping it harder for the planesman & helmsman to do their job makes them more alert and responsive.

Where are submarines constructed?

Modern submarines are typically constructed using modular design technology; here in the U.S., they are constructed at 2 major shipyards, General Dynamics Electric Boat Division (Groton, CT), and at Newport News Shipbuilding & Drydock Company, Newport News, VA. By Congressional mandate, there must always be at least 2 shipyards capable of building submarines and capital warships; there are 2 because U.S. contract law requires competitive bidding for defense contracts. EB has been in the submarine business for over a hundred years, being the United States' premier submarine builder. However, NNSDDC is no slouch either; those of us who served on NNSDDC boats during the Cold War felt much safer, as EB had problems with quality control during a period of about 15 years.

Modular design is relatively new (within the past 30 years) to the submarine construction industry; unlike the old practice of building a boat from the keel up, each hull section is fabricated apart, then the sections are welded together and systems connected. Though it took some time to work out the problems with a new procedure (first used on the Trident submarine program) the practice has shown that the yards can deliver boats faster and at projected cost. Relatively speaking anyway.

Most shipyards around the world that build submarines are typically involved in warship manufacturing to begin with, as the security clearances and military technology involved it costs a lot of money for background investigations of employees. This is why most contractor employees are usually ex-military - they're already cleared at the level required for the job their hired for, or just need an update, which costs far less than a full investigation, which can take a year for someone who isn't cleared, and who can't work on a project until they are.

Why do submarines need fins?

Well, darling, submarines need fins to help with stability and control underwater. Those fins act like the submarine's rudder, helping it steer smoothly through the depths. So, next time you see a submarine cruising along, just remember it's those fins keeping it on course.

Is German Submarine capitalized in a sentence?

German is. Submarine is not.

"A German submarine surfaced in the North Sea."

What are wind shields on a submarine?

A "windshield" on a submarine is a thick plexiglass shield about 4-5 feet long and 12-15 inches high that is used on the bridge (top of the sail) when the boat is underway transiting on the surface. Unless the weather is so bad that the bridge can't be manned, it is standard procedure for the bridge to be manned at all times by the Conn Officer and 2 lookouts. The shield helps divert the wind over the bridge crew, as watches are typically 6 hours and it can get pretty breezy in rough weather, when it is typically used.

The primary focus of manning the bridge on the surface with modern submarines is purely navigational - submarines are low in the water, black, and very hard to spot by commercial ships and other warships in low light conditions. Submarines on the surface transiting at night are required by maritime law to use a yellow blinking light to signal other ships a submarine is in the area. Even though Radar is used on the surface, it's not infallible, and 3 pairs of eyes with binoculars with a 360 view searching for surface contacts is considered an essential navigational safety measure.

It helps some, but if the weather is really bad it doesn't really make much difference one way or the other. Some submarines (Russian in particular) have enclosed bridges with windshields on the front and sides of the forward part of the sail. The reason the U.S. Navy and most others don't use that system is because it limits your field of view (you can't see behind you) and plexiglass gets pretty weathered when traveling underwater.

While on the surface (usually transiting to and from a port) it's common for crew to request permission to visit the bridge and get some fresh air and time to look around. The ocean is beautiful at night in calm seas, and Dolphins are usually around riding the ship's bow wave. It's one of the things I really miss about submarine life.

Did a submarine called Ulysses go to Atlantis?

Not in real life. The submarine Ulysses searched for Atlantis in Disney's 2001 animated film "Atlantis - The Lost Empire".

Why do women sponsor submarines?

It's not just Submarines - women sponsor all U.S. Navy ships and submarines, and most other countries do as well. It has not always been that way, and the christening tradition came to the U.S. from Europe.

The U.S. Navy originally had their christenings performed by men. The first recorded instance of a woman performing a christening was in 1827, on the Sloop-of-War Concord. Her name isn't known, and while it increasingly became tradition for women to sponsor, it wasn't universal.

The first known woman sponsor was Miss Lavinia Fanning Watson. She broke a bottle of wine and water over the bow of the Sloop-of-War Germantown on August 22, 1846.

The tradition of women as sponsors finally gained hold around the end of the 19th century. Wine is the traditional fluid, though it hasn't been exclusive (whiskey and seawater have been used among others). The first recorded instance of a U.S. Navy vessel being christened is the USS Constitution (Old Ironsides), whose Captain broke a bottle of Madeira wine over the heel of her bowsprit as she was launched.

Sailors (myself included) are an extremely superstitious lot, and it's been long held that any vessel not christened properly is a bad omen, and will bring bad luck to the ship and its crew. It's not an idle superstition either; there have been more than just one ship which wasn't properly christened that's had bad luck and recurring problems for both ship and crew throughout the ship's history. Some of the more recent examples of bad christenings (failure of the bottle to break upon striking the bow) and subsequent bad luck are the Costa Concordia, and several Carnival cruise ships.

The most famous example is likely the Mary Celeste, which was found adrift at sea, intact and under sail, but without her crew and passengers aboard. To this day it is still one of the most enduring and perplexing mysteries in maritime history.

Since Champagne is the top dog of all wines, it became the christening wine of choice, and it still is today. Over the past 50 years, women sponsors of ships bearing names of sailors have included wives, widows, or other female relatives. The Navy, being politically savvy, realized they could also score some points by asking wives of prominent Naval officers and Navy-friendly politicians to sponsor Navy vessels named after their husbands, and that practice continues today.

The political aspect is also why you see many capital ships being named after key politicians who have been friendly to the Navy or the Department of Defense in general.

Where were U-boats made?

Unterseeboots (U-boots, Anglicized to U-boats), those used in WW1 and WW2, were originally built in the shipyard owned by Krupp in Kiel, Germany. The first U-boat was the three-man sub Brandtaucher, built also in Kiel by the ship builders Schweffel & Howaldt in 1850. It sank during its first test dive in 1851 in Kiel Harbor, but was raised and placed in the Bundeswehr Military Museum in Dresden in 1887. Krupp built the Karp Class U-boats that were sold to the Russian navy for the Russo-Japanese war in 1904. Other U-Boat builders and the number of boats they built follow:

AG Weser, Bremen 162, Blohm & Voss, Hamburg 224, Bremer Vulkan-Vegesacker Werft, Bremen-Vegesack 74, Danziger Werft AG, Danzig 42, Deutsche Schiff und Maschinenbau AG, Bremen 16, Deutsche Werft AG, Hamburg 113, Deutsche Werke AG, Kiel 69, F. Schichau GmbH, Danzig 94, F. Krupp Germaniawerft AG, Kiel 131, Flender Werke AG, Lübeck 42, Flensburger Schiffsbau-Ges, Flensburg 28, H.C. Stülcken Sohn, Hamburg 24, Howaldtswerke AG, Kiel 31, Howaldtswerke Hamburg AG, Hamburg 33, Kriegsmarinewerft (KMW), Wilhelmshaven 27, Neptun Werft AG, Rostock 10, Nordseewerke, Emden 30, Oderwerke AG, Stettin 2, Stettiner Maschinenbau AG, Stettin 1.

Germany was not the only U-boat builder however. Swedish Thorsten Nordenfeldt built four: Nordenfeldt I, built at Stokholm Harbor by Bolinders--delivered to Salamis Naval Base in 1887 for the Hellenic Navy, it never saw combat; Nordenfeldt II (Abdülhamid, 1886) and Nordenfeldt III(Abdülmecid, 1887) for the Ottoman Navy, both were built in stages at Des Vignes, Chertsey, Surrey, England and Vickers, Sheffield, England, and assembled at Taşkızak Naval Shipyard in Istanbul, Turkey. Incidentally, Abdülhamid was the firstsubmarine to fire a torpedo while submerged. A fourth hull was built for the Russians in 1887, Nordenfeldt IV, but was scrapped when Russia refused to pay for the boat after it ran aground off Jutland.

What is the Naval abbreviation for Submarine Sonar Technician?

The designation for my old rate is "STS", which literally stands for "Sonar Technician, Submarines". Yours truly was an STS1/SS during the top years of the Cold War. Check my bio page for pics.

The Submarine Sonar community is an oddity in the Navy in that it is separate from the Surface Sonar community, though both share the same rate insignia and Naval lineage. Both have similar missions concerning ASW, but Submarine Sonar and Sonar Tech operations aboard a submarine are critical to submarine operations, whereas it's an ancillary function aboard a surface ship.

The rate insignia is denoted by a pair of headphones.

The surface equivalent, "STG", stands for "Sonar Technician, Guns".

What is the name of the Submarine in twenty thousand leagues under the sea?

Jules Verne novel became a Disney movie. The name of the submarine in that movie, Twenty Thousands Leagues Under the Sea was the Nautilus.

How much money do you get for designing submarines?

There is no single job for submarine design. Design is done by teams of engineers, working to specifications and performance standards set by contract with either General Dynamics (Electric Boat) or Newport News Shipbuilding and Drydock Company, at least here in the U.S. The contract will have what the Navy wants, and the 2 companies come up with a design they believe will fit the Navy's requirements. There are literally many engineers that work on the project. Design and development is usually a collaborative process that takes years. I remember being briefed by COMSUBLANT on the Seawolf-class design in 1985, long before it was built.

Salary depends also on who you're working for and what systems you're designing. Nuclear engineers tend to make more, and it also depends on whether you're military, civilian government, or a contractor. Contractor employees will always make more than their government counterparts, but many contractor engineers are also former Naval officers/engineers.

In the end it's really not about submarine design as it is about being an Electrical, Mechanical, Hydro, Electronics, Nuclear, etc. engineer and the going rate for your experience level in Naval engineering.
