Submarines

There is NO submarine called 'Typhoon' in the US Navy, nor has there ever been. Typhoon is a Russian nuclear submarine. -The current USS Typhoon is a 370 ton Cyclone class patrol launch..

The raised portion of a submarine above the deck is called the Fairwater or Sail; its primary purpose is to house the Periscopes, Radio masts, Snorkel Masts, and other equipment in a streamlined enclosure. It also serves as the Bridge / Lookout station during underway surfaced operations.

In WWI/WWI submarines, the tower was known as the Conning Tower, as it was this area where the Commanding Officer would "Conn" (control) the boat during target tracking / attack situations.

Submarines are not barbaric weapons. However, some tactics, such as unwarned attacks were considered by some during WWII as barbaric. As with most things, the thing is not bad, but how it is applied can be.

US Subs patrolled the world's oceans, including the Vietnam coastline. Other than possibly any covert operations, US submarines just patrolled, and kept an eye on any Soviet subs working in the South China Sea (Vietnamese Coastline).

Modern nuclear submarines make their own oxygen as needed by electrolyzing sea water.

The amount of oxygen carried by conventional submarines depends on the design and size of the particular submarine.

When the submarine is upto 20 meters from the surface they use a periscope which is simply 2 pieces of glass at 45 degrees to each other. similar to the periscope used to view from a trench by the army.

A submarine is fully autonomous, meaning it is capable of renewing its power supply and breathable air. A submersible however is not self sustaining and needs to be connected to another vessel for support.

No - microwave energy cannot pass through the water without significant signal attenuation / loss.

They can, however, receive signals through the primary periscope.

Areas when referring to submarines typically refers to a boat's Patrol Area, i.e., the specific region of ocean they are responsible for. It can be a coastal area, a sea lane, even a large section of ocean; it depends entirely on the type of boat and the mission requirements.

Patrol areas are classified and included in the orders given to the boat's Commanding Officer prior to getting underway. They are typically know only to the the crew and the Squadron command. In cases of training, where a boat is acting as a training target for surface ships, the area is know to both the ships and the submarine.

A simple mirror will allow you to see around a corner, but to see above an object or wall, you need two mirrors aligned in a certain way. See the related link below for more information and some very helpful diagrams.

On the older type of Fleet submarine, pre-nuclear. there were a minimum of Three steermen involved, plus the officer of the deck who had the overall *conn. The quartermaster maintained lateral control with a fairly conventional steering wheel- and remote compass repeaters, as there is no forward vision submerged. the Bow and stern planesman sat behind the QM usually on the right and worked large handwheels controlling the up and down angle on the two sets of diaplanes or dive planes- bow and stern, these were hydraulically linked- so says my l946 Naval tech manual. the planesman may have also had some control over the ballast tanks as their task was to maintain the up and down level. Ballast was always controlled by an officer, behind the Christmas Tree or master indicating panel(so called from Red and Green lights!) more modern subs have aircraft-like De-Haviland yokes and the two helmsmen control both the course and the up and down angle- like aircraft pilots- the ballast is still a separate post. it has been stated the three-wheel system is downright impractical at a submerged speed above 25 knots- so it is not used on modern nuclear subs- but older ones like the Nautilus had one steering wheel and two planesmen"s wheels or as they are somewhat incorrectly called Ballast wheels- so be it.

None, they were all lost during the great thermonuclear war that occured in the 1960's/

The first submarine wasn't invented in World War 1 but was invented in 1773 in the Revolutionary War by David Bushnell. It was called the Turtle.

The USS Greeneville collided with the Japanese fisihing vessel Ehime Maru in early 2001.

the turtle was built in 1775

Water is used for a variety of purposes on a submarine, the most common being for depth control (Main and Trim ballast). Main Ballast Tank water is expelled by pressurizing the tanks with either hi-pressure air (emergency blow) or low pressure air from a device known as a Low Pressure Blower. Hi-pressure air is dumped into the tanks during critical casualties when the boat needs to get to the surface quickly; the Blower is used when the boat is at Periscope Depth and can take its time to force the water out. The boat needs to be at PD to use the blower - it has to be able to bring in outside air through the snorkel mast.

Trim ballast is brought in and expelled using mechanical pumps. Like all boats, there is more than one pump in case one fails.

For unwanted water (flooding, bilge water, etc.) another pump is used to pump the water overboard.

Sanitary water - waste water from showers, heads, galley, etc., is forced overboard using hi-pressure air. It's also one of the reasons I don't eat fish.

Though Robert Fulton's submarine Nautilus (designed between 1793-97) was the first practical submarine design (it had a working ballast system and successfully dove to 25 feet), the primary reason he gave up was that it suffered from leaks. Additionally, though it had initially impressed the French during trials, when Napoleon wanted to see it, he found that Fulton had dismantled the Nautilus and destroyed many of its key components. Napoleon thought Fulton was a charlatan, and the French Navy had no use for what they believed then to be a suicidal machine.

The British, wanting to keep control over what appeared to them to be a potentially lethal device, brought Fulton to Britain to continue his work. However, with Nelson's victory over the French fleet at the Battle of Trafalgar, the French threat was eliminated, and Fulton was ignored until he finally left to return to America. His papers were left at the U.S. Consul in London, and went undiscovered until 1920. He never again worked on submarine designs.

Yes, the sail of the USS Birmingham is still around. If you're in the vicinity of Columbus, Ohio, you could drop by the Defense Supply Center there and set up for a photo op.

Nuclear Power wasn't introduced to submarines until the 1951 design of the USS Nautilus (SSN-571) several years after the end of WWII. All boats int WWII were of Diesel-Electric configuration.

The modern military submarines usually cruise around slowly to avoid detection and to hunt other submarines or perform other activities. But some, like the Los Angeles class boats, can top 33 knots. Top speeds are classified, as you can well imagine.

They use Radar , Sonar, and at periscope depth- optical range finders, the tech manual for the latter is over 300 pages, so its a skilled craft to operate these specialized sights.

About 2 Kilometres

A submarine can submerge by filling ballast and trimmer tanks with sea water. The additional weight will take the submarine down. To resurface, the submarine will blow the sea water out of the tanks using compressed air. The air in the tanks make the submarine buoyant, so it rises and floats on the surface. Though a stationary submarine can submerge in this way, it usually submerges going forward and using diving plane (fins) to steepen the dive, so getting under the surface faster.
