In the early 17 century Cornelius van Drebel invented the first submarine. The first submarine was built in England. It wasn’t until about 150 years after when they where first used in warfare (World’s First Submarine Attack). David Bushnell was the first person to successfully execute a attack with a submarine (World’s First Submarine Attack). "When the Turtle tried several times to sink British ships In the Hudson River but failed each time because of operator error" (World’s First Submarine Attack).Where is your thesis statement? you need it to be the last sentence in your introduction.

"Nuclear submarines use nuclear reactors, steam turbine, and reduction gearing to drive the main propeller"(Works). All old submarines used snorkels so they where very close to the surface of the ocean so they were very vulnerable to airplane attacks "Some have batteries to make them run off electric power but they have to be charged using either diesel or a nuclear reactor"(Works). Nuclear submarines have a advantage because nuclear submarines can be submerged for weeks or months on end and not have to surface. Another thing is that nuclear fuel lasts much longer that diesel fuel so they can stay at sea and not have to port for fuel (Works). Diesel engines can only work when surfaced or use a snorkel so the engine can breath. The Diesel engine submarines just surface to get the batteries charged than go back below the …show more content…
"When underwater the submarine uses internal guidance systems that keeps tract of the ship's motion from a fixed starting point using gyroscopes"(Works). "To locate targets submarines use a passive sonar, that works by emitting sound waves through water and allowing the sound waves to reflect off the target and return"(Works). There are a lot of things that make a submarine work the biggest thing has to be the pressure hull. It is the most important because when the submarine goes below the water there is lots of pressure pushing in on it. "Most submarines have two hulls one on the outside that is waterproof and another on the inside that is much stronger and resistant to immense water pressure"(Submarines). "The maximum depth that submarines ever dive is 2000 feet at that depth the pressure is sixty times greater than greater than at the surface"
Seaworld is has a lot of aquariums in the United States and all other the world . Many people in the past want to see and experience life under the sea. Seaworld was ideal place to do this. These locations including place in Orlando, San Diego, and many more. They main attraction is there Orcas which they have the largest population of Orcas than any other competitors. Orcas are killer whale, that they capture which very unethical because they are taking natural habitat which Orcas are dependent on.
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.
The Germans had sent out U-boats because they simply could no longer afford a purely defensive naval strategy. The Germans were the first to use torpedoes in battle to make their U-boats even more deadly. A torpedo is self-propelled underwater missile launched from a tube located on the deck or inside the hull of a warship. Torpedo tubes were first built into submarines in 1885 by the Swedish armaments manufacturer, Thortsen Nordenfelt. Torpedoes in 1914 carried a contact-triggered explosive warhead and had a range of 10,000 meters and could travel at 41 knots.1 However, their ideal range was about a kilometer because they tended to be inaccurate over longer distances.
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).
Navy Federal Credit Union headquarters is located in Vienna, Virginia. NFCU is the Largest Credit Union in the World, but when it was formed in 1933 it only consisted of 7 members. Now it has 7 million members with an outstanding workforce of over 15,000. It’s largest facility is in Pensacola, Florida. Navy Federal is currently on the “top 100” employer in America.
The U-boats one of Germany’s of most intimidating naval weapons. The U-boat, also known as a submarine, which is a boat that could go underwater. The common U-boat during World War One could carry 35 men and 12 torpedoes (history.com). The Germans would use the element of surprise by torpedoing ships such as their enemies or neutral countries.For example, the ship the Lusitania, a british ocean liner that had been coming from New York to Liverpool had been torpedoed without warning, which ended up killing 1,189 people. The Germans would use the U-boat for unrestricted warfare which caused the Germans’ to have one of the most
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]
Should seaworld be shut down? It's a difficult question to answer, or is it? After all the attacks seaworld has had, sometimes it’s hard to know what’s fact and what's fiction. On January 6, 2017 one of the most popular orcas, Tilikum died at seaworld orlando, florida which is a fact, However how he did is hard to say. Seaworld is not up for doing the autopsy, but why? What is seaworld hiding? What else is happening right under our noses? Some might argue that seaworld shouldn’t be shut down because they claim they are doing differently as of this year, however there has been no official changes to seaworld since 2013 (the release of “blackfish)
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
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.
It’s 2028 and the two nuclear giants are fighting against each other. Thousands dead, buildings in ashes and many hopes destroyed. Yet the worst is yet to come. The temperature of the world is decreasing to new records and is staying like that for many years to come. This is a nuclear winter that many scientists have predicted for decades. A nuclear weapon uses either uranium or plutonium. They work by using a nuclear reaction which breaks down an atom or nucleus into two pieces. This process produces a significant amount of energy which leads to an explosion. (Chan) A nuclear weapon can also be as big as a refrigerator or as small as a warhead. (Daniel) The first nuclear weapon was made in the 1930s known as the “Manhattan Project” made by the U.S. This project was suspended after Hitler was killed, but the U. S. used the weapon due to Japan attacking Pearl Harbor. This attack put the U. S. in a rage, so the U. S had a plan to use the weapon and another nuclear weapon. The U. S dropped a bomb named “Little Boy” on Hiroshima, which followed with the biggest explosion ever witnessed. Then the U. S dropped another bomb. (Lemouse) This was the first and last time anyone used a nuclear bomb, for now. While several people in the government and regular citizens argue that nuclear weaponry is stopping from giving any threats, but nuclear weaponry is actually causing an environmental turmoil and a radiation that will affect everyone in the vicinity for many ages to come.
