The UGM-84A, or the Harpoon missile is an anti-ship missile capable of engaging a variety of targets. Through technological advancements, harpoons can now be incorporated into every naval platform in order to combat various enemies. With its built in radar, targets can now be detected at longer ranges and precisely eliminated. This radar system also allows for efficient missile guidance during flight path. Each missile has different launch sequences, and varying bandwidths. This ability allows each variation to specialize in unique targets. There are many advantages to using Harpoons, but like any other weapon, also have many disadvantages. Regardless of the disadvantages, I believe Harpoons are an efficient means to combat enemies and should …show more content…
The Mark 140 is suitable for fast attack ships, while the Mark 141 is suitable for larger ships. The Mark 141 weighs 1.81 Tonnes more than the Mark 140. Regardless of their weigh differences, both are capable of launching missiles at equal speeds. In order to prevent recoil, and damage the platforms are inclined at an angle of 35 degrees, and the entire launching system is faced forward (Fuller, 19)). Each System is also equipped with four containers to increase firing capability (Craig, 53). The Mark 141 contains a shock resistant walls, with a support structure. Within the frontal tube are clamping frames, which hold the harpoon prior to launch. The central, and rear ends are held by stacking frames which allow multiple missiles to be stacked together. These frames provide armor protection against corrosion, and the elements (Craig, 37). The Mark 140 is similar to the Mark 141 except for its composition, and operational cycle. The Mark 140 has aluminum launchers designed for 15 refurbishment cycles . These containers are also held together by stacking frames, but are made with stronger metals. Submarine-launched harpoons are held in unpowered, buoyant capsules. These are structurally composed of a nose cap, the main body, and aft body. The nose cap has pressure sensors, explosive bolts, and a nose removal rocket (Fuller, 20). The main body utilizes shock isolation rails to guide missile out during the exit phase. The missile is combined with a sabot assembly at the nose to provide support and protection. The sabot straps are discarded during the exit phase. The aft body is combined with the rear of the missiles by pyrotechnic bolts. Each submarine has up to four
The Collins Class is a class of six Australian-built diesel-electric submarines operated by the Royal Australian Navy (RAN). The Collins Class Submarines are designed for long-range maritime patrol and response, maritime strike and support. The Defence Corporate Plan 1996-2000 states that introduction of the Collins Class Submarine into service is a key strategy in achieving Defence’s foremost objective of making the Australian Defence Force (ADF) capable of defeating any attack, which could credibly be mounted against Australia.
International Harvester built many good tractors over its years. Today I will be talking about the Super M-TA. The Super M-TA was International Harvester’s first tractor to have live power and other user friendly features. Before I talk about the tractor I’m going to give you a little International Harvester history.
For as long as most of the world can remember aviation has played a major factor in how wars are fought. Starting in World War I the worlds fighting forces began using aircraft to conduct surveillance missions over enemy territory. While these aircraft were not the masters of stealth that todays aircraft are there was no technology to take down these planes at the time. Air-to-air combat was an event that rarely happened and was almost never effective.
Air Defense Artillery (ADA) has been used in multiple battles, from World War I to the Iraq and Afghanistan wars. Although, different names have been used to label Air Defense Artillery, they have always served the same purpose, to destroy enemy air threats. During World War II, Air Defense Artillery was known as Anti-Aircraft Artillery. This title continued, even through the battle of the Kasserine Pass. The day of 19 February 1943 began a wretched and depressing battle for America and its allies. Located in Tunisia, the Kasserine Pass is about a two mile wide gap in the Atlas Mountains, where some of the U.S II Corps and British military held off and defeated the Axis offensive. Experience was lacking for the Anti-Aircraft Artillery
Every so often a man or women has an idea that is innovative, amazing or in some cases far ahead of its time. Unfortunately it is far too common that these ideas are lost or stifled by people who are afraid of the change they may bring. Since people also tend to believe if something seems too good to be true it probably is, these ideas may not get enough good attention until it is too late. Preston Tucker was one of these innovative people with a great idea. In 1944 he began work on a car that was safe, reliable, and groundbreaking. So far ahead of its time it made the wrong people nervous. The car was first christened as the Tucker Torpedo but due to concerns over torpedo not sounding safe, it was changed to the Tucker 1948. These amazing cars turned out to be one of the most revolutionary automobiles ever made and would have remained so if it weren’t for a slander campaign by the United States government.

For almost as long as civilizations began they have been fighting against each other. Often times these wars come down to who has the better military equipment. When one army creates an elite war machine another army is sure to soon copy or improve it. For example the U.S. Army Signal Corps purchased the first ever military aircraft in 1902 (Taylor). Two years later the Italians were also using aircrafts. The trebuchet catapult is no exception; it was one of the most destructive military machines of its time (Chevedden, 2000). A trebuchet works by using the energy of a falling counterweight to launch a projectile (Trebuchet). In this research paper I intend to explain the history and dynamics of a trebuchet catapult.
It all started on December 7th, 1941. America had entered their Second World War following the Pearl Harbor attacks. America started its Pacific Campaign against the Imperial Japanese Army. After three years, America joined with fellow allied nations and invaded Nazi- Occupied France codename Operation Overlord. This was the biggest amphibious invasion ever recorded. From Pearl Harbor to the fall of Berlin in the spring of 1945, the American bomber plane helped defeat the Nazi regime, end the war in the Pacific, and revolutionize modern warfare.
The U.S. Army Space and Missile Defense Command is working on a new active defense weapon system concept to enhance protection for combat forces and theater-level assets for the Force XXI Army. The mobile Tactical High Energy Laser, or THEL, weapon system would provide an innovative solution for the acquisition and close-in engagement problems associated with "dumb munitions" — a primary concern because counter-battery fire may not be an option in densely populated areas.
According to Merriam-Webster, nuclear fission is defined as “the splitting of an atomic nucleus resulting in the release of large amounts of energy” (Nuclear Fission). In the book Remembering the Manhattan Project: Perspectives on the Making of the Atomic Bomb and Its Legacy, Richard Rhodes, an American journalist and historian, states that fission was essentially discovered by accident. On December 21, 1938, German physicists, Otto Hahn and Fritz Strassman, were performing an experiment in which they bombarded uranium atoms with neutrons (Rhodes 17). They saw that this procedure created mutated atoms that had strange characteristics. Hahn and Strassman found that the neutrons split the nuclei of the uranium in half producing radioactive barium and krypton (Rhodes 18). Rhodes explains that the physicists observed that the reaction was extremely exothermic, producing about ten times the energy needed for the fission to occur. After publishing their findings, physicists all over the world recreated the experiment. After conducting his own fission experiment, Enrico Fermi, an Italian physicist at Colombia University, said, “A little bomb like that and it would all disappear” (qtd. Rhodes 19). Many of the world’s physicists came to the same conclusion; this reaction could be used to develop an atomic weapon. According to Rhodes, this discovery made the development of atomic weaponry seem essential to many countries because the only way to defend themselves against atomic weapons was to have similar weapons of their own.
Thompson explains every details and makes all the events that led up to the Cuban Missile Crisis are well informed.When I read Robert Smith Thompson's The Missiles of October, it was obvious that the Thompson was not a fan of Kennedy. Kennedy’s scandals and secrets were laid out in the story along with the facts. This story treated Kennedy’s presidency as a failure because of all the failed events that happened during his time. This story is very controversial and it shows the bias against Kennedy, but also has the facts that do show that Russian leader Khruschev actually beat Kennedy.Thompson says the familiar accounts of the crisis is a myth.
In the world, there are currently over 140 nuclear-powered ships, each of which is powered by more than 180 miniaturized nuclear reactors. Although most of them are submarines, they can also range from icebreakers to aircraft carriers. While there have been many people to contribute to the research and development of nuclear propulsion, none of them have been more influential than Admiral Hyman George Rickover, known as the “Father of the Nuclear Navy.” Accomplished in his naval career, he was a staunch defender of freedom from all who sought to undermine the sovereignty of the United States, or who would threaten our security. Though a controversial issue at the time, Admiral Rickover was passionate in his insistence for the development of
The graphic novel Trinity: A Graphic History of the First Atomic Bomb by Jonathan Fetter-Vorm follows the history of the first atomic bomb under the code name of Trinity. The novel opens with J. Robert Oppenheimer and Private Daniels approaching the scene of the Trinity testing site in a New Mexico desert on the day set for testing the first atomic bomb. Afterwards, the novel leads into a series of flashbacks consisting of the first discoveries of elements necessary in making the atom bomb. Not only did the novel inform about the discovery of elements, but also the novel informs about the make-up of an atom. With the knowledge of an atom and its components scientist found out that with nuclear fission it’s possible to cause an explosion so massive it could destroy entire cities. Uranium was the massive component that made the creation of the atomic bomb possible, but not uranium 238 the atom bomb needed uranium 235 for the bomb to work properly. There was a need for uranium 235, because uranium 235 is much more unstable compared to uranium 238. Then the novel goes to the night of the
The first solid fuel rocket was invented in 1805. Ever since then rockets have made a huge impact not only in the scientific world but also in everyday life. To build a model rocket and to get it to launch into the air succesfully does not involve much rocket science, but it does involve chemical reactions. Without a heart we wouldn’t be able to live, as with a rocket without an engine it would not be able to be a full rocket. To successfully make an engine to your rocket that will allow it to launch into the air and land you must use chemical reactions to generate a well built engine.
Nuclear weapons are the most powerful and destructive technology ever created. From the first notion that nuclear technology could be harnessed to create a bomb, massive amounts of time and energy (as well as government funding) have been invested in further increasing the destructive yield of nuclear weapons. The process of development was carried out independently by governments worldwide. Despite the segregation of groups of scientists and secrecy surrounding their discoveries, design strategies and problems remained basically the same in all development projects with similar solutions being realized more or less concurrently. The first and most basic fission bomb quickly evolved to produce higher and higher yields. Through discoveries and modifications, nuclear technology evolved to eventually produce fission-fusion weapons, which are what compose most of the nuclear arsenal today. Further development, ironic as it may seem, is highly unnecessary and unlikely (except, perhaps, to increase efficiency) due to the ridiculous power wielded in every modern thermonuclear weapon. The popular modern threat of nuclear weapons is the possibility of terrorist groups acquiring the materials to produce bombs. 'Lo-tech' nuclear weapons are feasible and would seem highly desirable for such groups to possess. The home enthusiast might even flirt with the idea of creating his or her own nuclear arsenal. Assuming one could obtain 10-20kg of highly enriched fissionable material, this may not be such a romantic idea after all. There are a number of things anyone must know about nuclear weapons, however, before declaring themselves a nuclear power.
