The fanatical introduction to the protagonist's magic pet

NMD:

The entire NMD is composed of: 2 launch positions, 3 command centers, 5 communication relay stations, 15 radars, 30 satellites, 250 underground launch silos and 250 interceptor missile systems.

Specifically, NMD is composed of five major parts, namely early warning satellites, improved early warning radars, ground-based radars, ground-based interceptor bombs and combat management command and control communication systems.

Early warning satellites are used to detect the launch of enemy missiles and provide early warning and information on the launch and landing points of enemy ballistic missiles. These satellites are space-based infrared systems, which means they rely on infrared radiation signals of fireworks ejected when the enemy launches missiles to detect missiles.

The modified early warning radars are the "eyes" of the NMD system and can warn up to 4,0004,800 kilometers away. In addition to improving the existing ground-to-ground bomb early warning radars deployed in Alaska and the "paving claw" radars deployed in California and Massachusetts, the United States also needs to build a new early warning radar in Asia.

Ground-based radar is an X-band, wideband, and large-aperture phased array radar that guides ground-based interceptor missiles into combat airspace.

The foundation interceptor is the core of NMD and consists of a booster rocket and an interceptor (warhead). The former sends the interceptor to the target's proximity, and the latter can automatically adjust the direction and height, collide with the target after finding and locking it, and shoot it down in space.

The combat management, command and control communication system uses computers and communication networks to connect the above systems.

After these systems are deployed, 24 low-orbit early warning satellites and 6 high-orbit satellites that rotate around the earth all day long. Once the enemy launches missiles, they will immediately track their infrared radiation signals. Through the combat management, command and control communication system, the satellites not only tell the missile's flight ballistics to the command center, but also indicate the target for the early warning radar and ground-based radar. After the early warning radar discovers the target, it transmits the missile's tracking and evaluation data to the ground-based radar. Once the launch order from the US Space Command is received, the interceptor takes off into the air. After the interceptor targets the incoming missile with its infrared detector, it will do its best (rely on kinetic energy) to collide with it and die with the other side.

introduce

Anti-missile missiles use infrared tracking principles to search for enemy offensive missiles, identify real and fake warheads, and then intercept enemy offensive missiles outside the earth's atmosphere and destroy them with laser weapons.

A:

During World War II, the Soviet Union was influenced by the 7.92mm urz bullet developed by Germany and also developed a 7.62mm M34 bullet on its own, and used it as standard ammunition. After World War II, the Soviet military began to develop a new generation of rifles, and domestic gun experts came out in an empty group. They designed their own sample guns, 1,945, Simon Nov's cc45 (some data is called SS) was used as standard equipment by the military. But unexpectedly, it has not been done yet.

How long after the next year, the sample gun designed by Kalashnikov defeated all opponents after multiple rounds of tests and tests. After the shaping, it began to formally equip the troops and replaced the original cc45, which is A-47. At that time, the A47 had two types of wooden butt stocks and folding metal butt stocks. The former was used by the air force, navy, service, and guard personnel, while the latter was used by paratroopers, tank drivers and special forces. For the sake of difference, the one with metal butt stocks was generally called A-47S.

The A-47 is a rifle that has both semi-automatic and fully automatic shooting mode. It uses a 30-round banana-type magazine. It adopts the traditional Soviet gun structure design. It is simple and reliable, solid and durable, and has a low failure rate. It is especially suitable for use in harsh environments. At the same time, the gun body is made of stamping parts, which is convenient for large-scale manufacturing in a short time and is cheap. These have laid the foundation for the widespread use of the A-47. I also heard that in Pakistan and Afghanistan, the A-47 implements "small profit but quick turnover" and you can buy one for $80!

However, the A-47 is not a perfect rifle, and it also has some shortcomings. First of all, it is known that the muzzle jumps seriously when firing, which affects the shooting accuracy, especially at long distance shooting accuracy (but at the same time, because its bullet is small and easy to control, the suppression ability of continuous shooting at close range is quite high). Secondly, the design defects of the insurance make it easy to cause fire escape. In addition, the wind offset cannot be corrected when installing sighting equipment, and night shooting is easy to mistakenly use the sighting wing as a sighting, etc.

Hummar

The American AMG company is famous for producing Hummers. The founder of AMG company is Utter, a bicycle manufacturer. In 1903, he established the Overland Automobile Department. In 1908, John Willy purchased the Off-road Automobile Department and established the Willys Overland Automobile Company in 1912 to produce Willys Knight Automobile. On July 11, 1940, during World War II, the US military issued research to 135 companies.

The bidding for a light reconnaissance vehicle was made with harsh conditions and tight time. Three companies including Ford announced the bid, one of which was Willis Off-road Vehicle Company, which produced the earliest Jeep "WillysMA". Later, the military combined the product advantages of the three companies, took WillysMA as the basis, and commissioned Willis Off-road Vehicle Company to re-standardize the design. This standardized car was WillysMB. By the end of World War II, Willis Company produced 360,000 WillysMB Jeeps.

In 1953, the businessman Kasai purchased Willis Off-road Vehicle Company, which was renamed Kesai Jeep. In 1970, the American Automobile Company (later merged by Chrysler Automobile Company) purchased Kesai Jeep, which was later changed to Jeep. The company consists of two independent departments, including the Department of Commerce and the Department of Government and Automobile. In 1971, the Government and Automobile Department became a subsidiary of the American Automobile Company - AMG Automobile Company. In 1980, AMG took over another military vehicle design task of the US military and designed the Hmmwv off-road military vehicle. In 1983, the American LTV Company purchased AMG Automobile Company from the American Automobile Company. In 1992, AMG transferred to the Renco Group. In the same year, AMG launched the Hummer, the Hummer off-road vehicle, which was hailed as the "off-road vehicle king" by people inside and outside the industry for its excellent operating performance.

HUMMERH2 (Hummer H2): Hummer is the most veritable 4-wheel drive off-road vehicle in the world. It has been the leader of the many heroes for many years. H2 respects the power and domineering of the current Hummer, carries forward its fine traditions, modernizes it while retaining and improving this vigorous and strong American idol, thereby expanding the Hummer user base. The purpose of H2 is not to recreate Hummer, but to show the development direction of this brand and call on more people to experience Hummer, especially those with adventurous spirit. Manufacturer: General Hummer Automobile Brand: Hummer Manufacturer Quotation: 1.05 million domestic (RMB)

Apache:

The anti-tank armed helicopter developed by Hughes Helicopter in 1975 has a maximum level flight speed of 307 kilometers per hour, a practical ceiling of 6,250 meters, a maximum rise rate of 16.2 meters per second, and a range of 578 kilometers.

Main weapons: The rotating turret of the nose is equipped with a 30mm chain anti-tank gun, 4 external points can hang 8 anti-tank missiles and tools, and a 19-mounted rocket launcher. The maximum take-off weight is 7,890 kg. The aircraft is also equipped with a target interception display system and night vision equipment, which can search, identify and attack targets under complex weather conditions. It can effectively destroy medium and heavy tanks, has good survivability and ultra-low-altitude ground-flighting ability, and is a contemporary American main combat armed helicopter. The AH64 "Apache" helicopter is the first in the United States.

Armed with all-weather, day and night combat capabilities. 22 minutes before the Hellak launched a large-scale air strike, eight Apache attack helicopters took off from a base 750 kilometers away and launched three Haierfa missiles. The missile flew along the beam to two ground radar stations in western Iraq. In less than 2 minutes, it was completely destroyed, thus providing a safe corridor for the air strike troops and ensuring the success of the air strike. Later, the record of an AH64A Apache attack helicopter destroying 23 tanks was recorded in history.

Compared with other helicopters, the outstanding features of the "Apache" are:

(1) Strong firepower, it uses anti-tank missiles as its main weapon, and there are also machine cannons and rockets;

(2) Good armor protection, bullet injury tolerance and sinker performance;

(3) Fast flight speed;

(4) The combat radius is large, which can reach about 200 kilometers;

(5) Airborne electronics and fire control equipment are complete, with high all-weather combat capabilities and a relatively complete fire control, communication, navigation and night vision systems;

(6) Have the ability to "one machine and multiple uses".

Boeing 747

The Boeing 747 is a four-engine (motor) long-range wide-body transport aircraft produced by Boeing. It is a wide-body passenger aircraft with successful development and sales. It began development in August 1965, and the prototype was tested in February 1969. In January 1970, the first 747 was delivered to Pan American Airlines for route operation, creating a new era of wide-body passenger aircraft service. Its double-decker cabin and unique exterior have formed the easiest subsonic civil aircraft. Of course, unfortunately it has become the first choice target of terrorists to destroy. Since the Boeing 74

Since the 7 aircraft was put into operation, it has been monopolizing the market for large transport aircraft, and this situation will not change in recent years.

Since May 1990, except for the 747400 model, all other models have been discontinued.
