Process Essay: How Do Submarines Work?

The Makings Of A Navy SEAL by Brandon Webb and forwarded by Marcus Luttrell is about Brandon Webb's life on his journey becoming a Navy SEAL. Brandon went through very tough times and also learned how much it took to become a Navy SEAL. After reading this book, I became captivated on Branon’s life. I think that he was a great person and was surprised how much he had to go through to become a Navy SEAL and a Navy SEAL sniper.

The United States of America has not always been the world superpower that it is today. The same goes for its Navy. In the first several years of existence, the United States Navy was not a formidable fighting force. The young nation was hesitant to invest in a navy for many reasons, one of them being to prevent provoking the world powers of the time, France and Britain. On top of that, navies were very expensive to build and required a significant amount of resources to maintain, which the U.S. did not have at the time. To say that the United States Navy was ill prepared for war would be a dramatic understatement. The U.S. had a total of fifteen ships in its entire naval fleet compared to the might of the Royal Navy which possessed over six hundred warships. Even with the odds stacked against the U.S., President Madison declared war on 18 JUN 1812. The lack of size and power of the navy at the time would make it extremely difficult to satisfy the needs of the newly founded nation.

This separation presented communication and data-sharing challenges. Furthermore, the new design contained a number of technical risks, one of them was designing a submarine that would operate in a manner and environment very different from what Kockums was accustomed to. The risk resulted fuel system has been proven to be problematic. Swedish submarines have short patrols in calm, relatively fresh water. When a similar design was used in the salty, open water in which Australian submarines operate, water was sucked into the engine causing failure. Moreover, the RAN submarines transit greater distance and are on station for months at time, which has number of implications for fuel storage, hotel service, and other hull design features. The difference in operation concept and environment ultimately led to some equipment and system decision during design that caused problems with operations and supportability.

They soon discovered the submarines bow planes were buried; the bow tanks full of sand. The propellers were torn off, steering gear ruined, stern tanks flooded, and all the hatches were desperately jammed.

Not only did we have ships, but we had a device called the Turtle. Invented nearly 150 years before, it was not until the Revolutionary War that the submarine would be used in combat. A man named David Bushnell would develop the Turtle to deploy underwater mines. The Turtle would fail all of its missions and would be lost at the Battle of Fort Lee when the ship transporting it would be sunk. “Despite the failures of the Turtle, General George Washington gave Bushnell a commission as an Army engineer…After the war, he became commander of the U.S. Army Corps of Engineers.”(History 1).

A diver descending to a depth of 10 meters, is equivalent to the entire 150km of atmospheric air (1 ATA). This is due to water being much denser than air. If the diver were to descend another 10 meters, the water will exert a further pressure, equal to another atmosphere, 2 ATA.

​The German U-Boats were like a submarine that was a lot more advanced than those that were built by other nations; and they were the first submarines made by the Germans. The U-boat was 214 feet long, it could carry 35 men, and 12 torpedoes at a time. And it could travel underwater for 2 hours at a time. With these Germany had a lot of success against the British warships. (https://www.britannica.com/technology/U-boat)

A submarine is defined as “something that functions or operates underwater; specifically: a naval vessel designed to operate underwater.” This definition holds true today but started at the beginning of the Civil War when submarines originally became a popular choice of weaponry. In general, submarine crews were composed of a commander, who steered the boat, and six or more men who used hand cranks to move the boat. Many inventors intended on creating electric motors to move the boat, but they were unable to produce enough torque. Submarines were primarily used in combat because they could travel invisibly. Innovations like submarines did not just change the way people fought wars–they also changed the way people lived.

Before World War II, the submarine was very predictable and easily managed with detection systems, depth detection, and antisubmarine forces. The aircrafts were harder to manage, and could easily penetrate enemy territory. It was not so predictable.[xii]

First of all, ocean exploration technology has advanced much more than before in the past decade. In the past, people had to bring everything needed for scuba diving which included hundreds of pounds of gear and photographing technology. Now, all

The Collins Class submarine was prone to excessive noise signatures whilst travelling at speed and lacked the operational capability to enter conflict situations due to the

Experienced divers can even take in the wreck of an old passenger ferry sunk south of Possession Point and the submarine creatures that now call this sleeping vessel home.

The United States Navy Diving Manual contains a wealth of information about diving from the history of diving to underwater physics and physiology. Start by browsing the U.S. Navy Diving Manual (located within the weekly readings) and then post a response to the following questions:

Submarines were effective and best known for sneaking on the enemy. They were lightly armored and served as easy prey if discovered. It also had small crew numbers which made it hard to take prisoners from captured steamships. Despite these reasons, the Germans were non reluctant to break the international rules of warfare. The Germans attacked and sank the British passenger ship carrying American civilians on board. The American people were in disbelief and accused Germany of violating international rules. However Germany disagreed to the accusations.

Years before the submarine was created, Jules Verne created s sub type vehicle in "20,000 League Under the Sea,"
