E-Bomb

E-Bomb, or the electromagnetic bomb, is designed to destroy machines that use electricity. Generators would be useless, cars wouldn't run, and no chance of making a phone call. A big enough bomb would set a city back 200 years or cripple a whole military unit. The U.S. military has been pursing the idea of an e-bomb for a while, and many believe that they already have one in their arsenal.

What is an E-Bomb?

The E-Bomb releases a nuclear explosion, which results in electromagnetic radiation and causes to electric machnies to surge and produce high voltage bolts. This bomb does not last, there is only a short burst and causes widespread damage to electric machines. The E-Bomb relies on the altidude of detonation, energy yield, interactions with the Earth's magnetic field, and sheilding of targets.






The E-Bomb is a hopeful goal of the U.S. military because ultimately they wish to have this technology to explode artillery shells in midflight. The E-Bomb releases 2 billion watts or more, which the Hoover dam can produce 24 hours. Mechanics argue a basic weapon of this sort can be made with $400.

Hypersonic Cruise Missile

The Hyrpersonic Cruise Missile will be able to travel more than 600 miles in less then 10 minutes. With this speed, the army would be able to attack almost any target they want in less than a hour. With this power, also comes fear of many things. In this case the Pentagon fears that this fire power may start a Nuclear War. But the Military is convinced that with this missile, they may be able to strike out against enemies in matter of minutes or hours. This enemy may be terrorists or smuggled nuclear or arms dealers. "We know how to strike precisely. We know how to strike at long distances," says Kehler, whose office is in charge of the Defense Department's Global Strike mission. "What's different now is this sense of time." This missile may be a good thing to use to save lives, but it costs $60 million.
The cruise missile can travel at 3600 MPH or March 5. This missile is able to anywhere on the face of the Earth in at least 60 minutes. Protests started that this missile could start a nuclear war. Compared with the Tomahawk Missile which travels at a mere 550 MPH, the X51 gives the US the ability to strike enemies quickly before they can evade.

The warheads are filled with tungsten rods with twice the strength of steel. Just above the target, the warheads detonate, showering the area with thousands of rods-each one up to 12 times as destructive as a .50-caliber bullet. Anything within 3000 sq. ft. of this whirling, metallic storm is obliterated. The X-51 Will be the most advanced cruise / long distance missile in the world when it is completed.

X-51 is a "wave rider," with a sharp nose shaped to make the waves break at precisely the right angle. All of the pressure is directed beneath the missile, lifting it up, instead.

The waves also compress the air, as it passes through them. That’s critical for the X-51. Because unlike a rocket, say, the aircraft doesn’t carry an oxidizer, to mix and burn with its fuel. Unlike a jet, it doesn’t squeeze the air with a turbine. In fact, the X-51 barely has any moving parts at all. It’s an
"air breather." The shock waves do most of the compression work.

The air passes into an inlet at the bottom of the X-51, mixes with a mist of JP-7 diesel jet fuel, and is lit on fire at several spots, one after the next. That produces tremendous thrust â?? and unimaginable heat, up to 4500 degrees. The X-51 uses the warmth, too. The diesel fuel cools the walls of the machine, to keep the thing from melting. As the fuel absorbs all that heat, the diesel breaks down â?? making it easier to burn, when the air comes whooshing through. And the cycle starts again, just a ten-thousandth of a second after it begins.

The Smart Bomb

The smart bomb is usually deployed by stealth bombers and then attack their targets. This bomb is cheap to produce and steerable which allows for precision attacks. However, the system used to navigate these bombs is expensive and the military has to choose wisely when to use these missiles. The best choice is to use the Owl bomb by Lockheed Martin. When launched it extends its wings and is controlled from a plane nearby that helps it steer to its target and recalculate its aim. The dumb bombs can work in bad weather, night, and smoke and dust don't affect it.

The smart bomb can be guided to their targets with an even higher degree of accuracy. These bombs are equipped with small extendable wings which help it glide and a camera in the nose of the missile to help it be maneuverability.

The smart bomb falls to the surface due to gravity but its wings help it glide to its target. The wings have control surfaces on them that move in response to guidance commands, enabling adjustments to be made to the angle of the bomb's descend or the direction of its fall. the guidance system is planted in the nose of the missile. This system could be electro-optical, laser, or infrared. The system consists of sensors to detect the target and soem means of adjusting the bomb's descend.
