Saif AbdulAzez nuclear missile system Introduction : Why we build our own nuclear weapon? To answer this question, we should predicting the long term future of national security, we should feel the importance of owning such weapon. Our faith in the human progress of military technology is one of the most important data to enforce respect for peoples and the imposition of coexistence. what can be done now to start to have arsenals and creating the political and security conditions that would be needed for an effective and realty political . Description : We can say the manufacturing of nuclear weapon with a component which are available locally , Become realistic possible. Depend to the manufacture the missile and nuclear warhead by assembly components are available, such as, Jet engine, cooling system, generator ,fuel tank. General vision : Iran claims that its nuclear program is exclusively for peaceful purposes, it has generated considerable concern that Tehran is pursuing a nuclear weapons program. the UN Security Council has responded to Iran's refusal to suspend work on its uranium enrichment and the nuclear reactor programs . Despite this pressure, Iran continues to enrich uranium, install additional centrifuges, and conduct research on new types of centrifuges. Tehran has also continued work on its heavy-water reactor and associated facilities. Whether Iran is pursuing a nuclear weapons program is, however, unclear. Tehran "halted its nuclear weapons program," defined as "Iran's nuclear weapon design and weaponization work and covert uranium conversion-related and uranium enrichment-related work, Political situation : Since the early 1990s, Israel, U.S. officials and their submissive European allies, supported by their uncritical and subservient media, have been peddling allegations, fabrications, accusations and lies that the government of Iran was pursuing a secret, military adjunct to its regularly inspected civilian nuclear program. all facts is to demonstrate that this crisis was „manufactured“ and the accusations were bogus, i. e. Iran never had a military nuclear program. For over 20 years Israeli politicians have been claiming that Iran’s nuclear device was just around the corner. Despite the political hullabaloo and Netanyahu’s call for military actions against Iran’s nuclear installations. „Netanyahu never intended to use military force against Iran, and the Obama administration was well aware of that but was hoping to exploit the threat to gain diplomatic leverage on Iran. Challenges : Saudi Arabia traces its roots back to the earliest civilizations of the Arabian Peninsula. Over the centuries, the peninsula has played an important role in history as an ancient trade center and as the birthplace of Islam, one of the world’s major monotheistic religions. At this time we remember its massive achievements in growth and development which are a result of the strategies that have been implemented since the rule of its founder King Abdulaziz Al Saud until today under the rule of the Custodian of the Two Holy Mosques His Majesty King Salman ibn Abdulaziz, Who was and still looks to be Saudi Arabia one of the most important military force in the region. Through all sectors of the military Ground forces , sea forces and air defense represented by the Ministry of Defence At the forefront of His Royal Highness Crown Prince Mohamad bin Naief bin Abdulaziz and the vision of the government support, which includes other areas represented by sir Crown Crown Prince Mohamad bin Salman bin Abdul Aziz and Saudi people loyal. The main components : 1- Nuclear warheads The principle of nuclear warhead pre-set based on five steps as fowling: - Effect on the nitrogen atoms by Electricity estimated 1800 Volt. - Transformation of nitrogen to helium. - Neutrons are released. - Fusion has occurred. - Explosive to start the nuclear chain reaction. 2- Fuel tank the Board of Chief Designers forwarded a proposal to the Russa Government to develop after further studies OKB-1 proposed to design two options of the rocket distinguished by propellant components and propulsion units: R-9A (on cryogenic propellants - kerosene and liquid oxygen) and R9B (on hypergolics - kerosene and nitric acid). Such a proposal was attributed to the fact that at the given juncture it was not completely clear what pair of propellants would ensure better operational conditions in the forces and a shorter pre-launch processing time. That depended on the complexity of systems maintaining propellants in a proper condition for filling, toxicity of propellants, time required for the rocket fueling, and time needed to run-up gyroscopes before a launch. Having regard to the fact that the prelaunch readiness time was about the same for both versions and kerosene-oxygen propellants were preferable from the viewpoint of operational characteristics including the rocket handling safety, OKB-1 insisted on further development of rocket R-9A. 3- Generator The mechanical power for an electric generator is usually obtained from a rotating of the missile shaft and is equal to the shaft torque multiplied by the rotational, or angular, velocity. Nearly all generators used to supply electric power networks generate alternating current, which reverses polarity at a fixed frequency (usually 50 or 60 cycles, or double reversals, per second). 1800 Volt Since a number of generators are connected into a power network, they must operate at the same frequency for simultaneous generation. They are therefore known as synchronous generators or, in some contexts, alternators. 4- Cooling System An integral cooling system for high temperature missile structures which is essentially a passive cooling system integrated into the missile structure. An evaporative material carried in the missile structure is ejected by vapor pressure through openings in the missile's outer skin and cools the missile as it flows along the outer surface thereof. 5- Jet engine All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The compressor is made up of fans with many blades and attached to a shaft. The blades compress the air. The compressed air is then sprayed with fuel and an electric spark lights the mixture. The burning gases expand and blast out through the nozzle, at the back of the engine. As the jets of gas shoot backward, the engine and the missile are thrust forward. Jet engines move the missile forward with a great force that is produced by a tremendous thrust and causes the missile to fly very fast. Recommendations Carbon Fiber: Carbon fiber is, exactly what it sounds like – fiber made of carbon. But, these fibers are only a base. What is commonly referred to as carbon fiber is a material consisting of very thin filaments of carbon atoms. When bound together with plastic polymer resin by heat, pressure or in a vacuum a composite material is formed that is both strong and lightweight. Much like cloth, beaver dams, or a rattan chair, the strength of carbon fiber is in the weave. The more complex the weave, the more durable the composite will be. It is helpful to imagine a wire screen that is interwoven with another screen at an angle, and another at a slightly different angle, and so on, with each wire in each screen made of carbon fiber strands. Now imagine this mesh of screens drenched in liquid plastic, and then pressed or heated until the material fuses together. The angle of the weave, as well as the resin used with the fiber, will determine the strength of the overall composite. The resin is most commonly epoxy, but can also be thermoplastic, polyurethane, vinyl ester, or polyester. Alternatively, a mold may be cast and the carbon fibers applied over it. The carbon fiber composite is then allowed to cure, often by a vacuum process. In this method, the mold is used to achieve the desired shape. This technique is preferred for uncomplicated forms that are needed on demand. Carbon fiber material has a wide range of applications, as it can be formed at various densities in limitless shapes and sizes. Carbon fiber is often shaped into tubing, fabric, and cloth, and can be custom-formed into any number of composite parts and pieces. Familiar products made of carbon fiber include. Conclusion : How to Make an Atomic Bomb? (The traditional way) Step 1 - What is a nuclear fission bomb? Fission bombs derive their power from nuclear fission, where heavy nuclei (uranium or plutonium) are bombarded by neutrons and split into lighter elements, more neutrons and energy. These newly liberated neutrons then bombard other nuclei, which then split and bombard other nuclei, and so on, creating a nuclear chain reaction which releases large amounts of energy. These are historically called atomic bombs, atom bombs, or A-bombs, though this name is not precise due to the fact that chemical reactions release energy from atomic bonds (excluding bonds between nuclei) and fusion is no less atomic than fission. Despite this possible confusion, the term atom bomb has still been generally accepted to refer specifically to nuclear weapons and most commonly to pure fission devices. Step 2 - What do you need? a. The fissionable material Plutonium239 isotope. Around 25 pounds (10 kg) would be enough. If you could find some Uranium235, that would be good, but not great. You would need to refine it using a gas centrifuge. The uranium hexafluoride gas is piped in a cylinder, which is then spun at high speed. The rotation causes a centrifugal force that leaves the heavier U-238 isotopes at the outside of the cylinder, while the lighter U-235 isotopes are left at the center. The process is repeated many times over through a cascade of centrifuges to create uranium of the desired level of enrichment. To be used as the fissile core of a nuclear weapon, the uranium has to be enriched to more than 90 per cent and be produced in large quantities. b. The explosive to start the nuclear chain reaction 100 pounds (44 kg) of trinitrotoluene (TNT). Gelignite (an explosive material consisting of collodion-cotton (a type of nitrocellulose or gun cotton) dissolved in nitroglycerine and mixed with wood pulp and sodium or potassium nitrate) would be better. Semtex would be good too, but it's a bit hard to get, these days. c. The detonator To fabricate a detonator for the device, get a radio controlled (RC) servo mechanism, as found in RC model airplanes and cars. With a modicum of effort, a remote plunger can be made that will strike a detonator cap to effect a small explosion. These detonation caps can be found in the electrical supply section of your local supermarket. If you're an electronics wiz, you should be able to make it using a cellphone. d. The pusher The explosion shock wave might be of such short duration that only a fraction of the pit is compressed at any instant as it passes through it. A pusher shell made out of low density metal such as aluminium, beryllium, or an alloy of the two metals (aluminium being easier and safer to shape but beryllium reflecting neutrons back into the core) may be needed and is located between the explosive lens and the tamper. It works by reflecting some of the shock wave backwards which has the effect of lengthening it. The tamper or reflector might be designed to work as the pusher too, although a low density material is best for the pusher but a high density one for the tamper. To maximize efficiency of energy transfer, the density difference between layers should be minimized. Step 3 - How to build the nuke? You will need to get the fissile material to the critical mass in order to start the chain reaction, which depends upon the size, shape and purity of the material as well as what surrounds the material. Your weapons-grade uranium will have to be in subcritical configuration. First, you must arrange the uranium into two hemispherical shapes, separated by about 4 cm. Since it's highly radioactive, the best way do it is to ask the friend owning the small country to let you use one his facilities. You could use a nuclear plant, a steel factory or even a well equipped pharmaceutical installation as a disguise for your plans. It is not sufficient to pack explosive into a spherical shell around the tamper and detonate it simultaneously at several places because the tamper and plutonium pit will simply squeeze out between the gaps in the detonation front. Instead, the shock wave must be carefully shaped into a perfect sphere centered on the pit and traveling inwards. This is achieved by using a spherical shell of closely fitting and accurately shaped bodies of explosives of different propagation speeds to form explosive lenses. After a few careful calculations, all you need now is to carefully pack and transport your nuclear bomb to the targeted location. If you happen to be an AlQaeda fan, you should try to infiltrate a military facility, for the psychological effect. Watch it, though, they are usually well guarded! Step 4 - Disguising the bomb and placing it for detonation The smallest nuclear warhead deployed by the United States was the W54, which was used in the Davy Crockett recoilless rifle; warheads in this weapon weighed about 23 kg and had yields of 0.01 to 0.25 kilotons. This is small in comparison to thermonuclear weapons, but remains a very large explosion with lethal acute radiation effects and potential for substantial fallout. It is generally believed that the W54 may be nearly the smallest possible nuclear weapon, though this may be only smallest by weight or volume, not simply smallest diameter. The best way to disguise it would be in the form of an ordinary appliance, like a copier, a widescreen TV set, or any other inconspicuous electronic device. Now, all you have to do is transport it to the selected location and get to a safe distance of a few tens of miles, but not far enough to get out of the range of the remote detonator. That is why a cellphone is strongly recommended for its wide range capabilities. (Theory) The principle of nuclear warhead pre-set based on five steps as fowling: - Effect on the nitrogen atoms by Electricity estimated 1800 Volt. - Transformation of nitrogen to helium. - Neutrons are released. - Fusion has occurred. - Explosive to start the nuclear chain reaction.
