On a quiet night, when you and your friends are enjoying the stars in the open air, suddenly, a flash of fire cuts through the sky. Please don't cheer, or make a wish to it, because it may not be beautiful in the legend. It also brings lucky meteors...
According to the report of the US "Defense News" weekly website, the U.S. military has begun to develop a space weapon named "The Staff of God." The project plans to rely on the space platform to carry a large number of metal rods made of tungsten, titanium or uranium with a diameter of 30 cm, a length of 6.1 meters and a weight of 100 kg. These high-density metal rods can be guided by satellites, using small rockets to boost and The tremendous kinetic energy generated by freefall can be used to quickly and precisely strike high-value strategic targets in any region of the globe at any time. What is even more unbelievable is that after launching from space, the "God's Staff" does not rely on any ammunition and is completely dependent on kinetic energy to impact on the target. However, the effect of the "God's Staff" is comparable to nuclear weapons and can easily destroy large buildings. Groups and underground bunkers a few hundred meters deep, but also will not produce radiation. The U.S. military hopes to build the "God's Staff" into the "killer" of future space-to-Earth operations, replacing the displeasing nuclear weapons and becoming a new strategic deterrent in the military field.
Sword walking slanting in the sky
In fact, as early as the 1980s, the U.S. military had a preliminary idea for the development of the "God's Staff." Allegedly, this inspiration for the US military came mainly from two legendary accidents: one was that a woman had died of a frozen urine column dropped by an aircraft toilet; the other was that someone had accidentally tossed in the Empire State Building. In the next coin, the coin punctured the pedestrian's head like a bullet.
Of course, the U.S. military has broken through conventional thinking and opened up new avenues. There are also deep reasons for developing this new concept of strategic weapons. As nuclear weapons are not unique to the United States, the deterrent power of traditional strategic weapons centered on nuclear weapons is greatly limited. In addition, the international anti-nuclear wave is also a climax. After the accident at the Fukushima nuclear power plant in Japan, people talked about “nuclear†changes. There is a huge expenditure for maintaining nuclear deterrence. According to U.S. officials, the total cost of maintaining its nuclear weapons is between 2,000 and 300 billion U.S. dollars each year, and a nuclear weapon needs 80 million to 160 million U.S. dollars. This is undoubtedly for increasingly tight military expenditures. It is worse.
At the same time, other conventional weapons often do not possess strategic deterrence capabilities. For underground works that are getting deeper and stronger, conventional weapons often do nothing. Take the U.S. Army's GBU-28 “bunker mill†drilling bomb as an example. It can penetrate only 6 meters of concrete or 30 meters of hard strata. There is no way for the underground reinforced concrete construction.
These multiple factors have prompted the U.S. military to seek new breakthroughs and new strategic heights in other non-nuclear weapons. Space-based kinetic energy weapons represented by the "God's Staff" will undoubtedly be the best choice.
System design is very simple
　　 According to reports, the “God's Staff†space-based kinetic energy weapon system consists of two satellite platforms in low orbit, one for communication and locking targets, and the other carries a large amount of metal known as the “God's Staffâ€. Long rod-shaped kinetic energy "cannonball." The projectile is mainly composed of a kinetic energy warhead, a propulsion system, a guidance system, a thermal control system and a communication system. The warhead is mainly cast from high-density metal such as tungsten, titanium or uranium. The nose is slightly pointed to reduce the air resistance and reduce the kinetic energy loss when reaching the ground. The propulsion system is mainly a small rocket booster that can provide more accurate and easily controllable thrust for "shells" in outer space. The guidance system is mainly to constantly adjust the rocket booster and aerodynamic rudder surface, change the direction of flight, and ensure accurate hit targets. The thermal control system mainly relies on external special thermal protection coatings to prevent the bomb from overheating.
The "God's Staff" usually strikes a target with a vertical attack, just like a meteorite hits the earth. As a result, the kinetic energy it gains is huge. The destructive power generated when it strikes the ground is also quite large. Its power is equivalent to a small nuclear bomb. It can easily pierce the inside of a target within a few hundred kilometers of the ground. Only this one can eclips any earth-bombing bomb. According to the Pentagon, they plan to complete the deployment of the "God's Staff" by 2025.
Expected results are not general
When the "God's Staff" is mentioned, people naturally compare it with the Rock and think of the extinction of the dinosaurs. Some 65 million years ago, it was probably a meteorite with a diameter of about 10 kilometers that crashed into the earth, leading to the extermination of a powerful species that ruled the earth. So, does the "God's Staff" have such a great power? According to the US military's assumption, the “God's Staff†can enter the atmosphere at an initial speed of 11 km/s, and even if the speed drops when flying in the lower atmosphere, it still maintains an attack speed of 11,200 kilometers per hour. The "God's Staff" of the kilo-class quality is basically equivalent to the destructive energy produced by the tonnage TNT equivalent. A tungsten bullet with a length of approximately 1 meter and a mass of approximately 120 kilograms can strike a steel material and cause a crater with a depth of 1.5 meters and a diameter of 1 meter. Although its damage capability is far from the meteorite that led to the extinction of dinosaurs, it is a piece of cake for the important targets against the enemy's ground and the underground bunkers that are hundreds of meters away.
Compared with other conventional weapons, the "God's Staff" also has the following advantages: First, a wide range of attacks. Its range of attacks can cover any region in the world. Targets include all non-mobile targets such as command centers, missile launchers, and underground bunkers. The second is the short reaction time. Because its platform is usually deployed on a low orbit, the preparation time for ground attack is short and the response speed is fast. It takes only 11 minutes from off-track to the ground to strike, and the strike time is less than one-third of the intercontinental ballistic missile. The third is the strong penetration ability. Due to its extremely high speed, it can effectively break through the enemy's multi-layered defense system. Even if the enemy has multiple layers of defense capabilities, it is difficult to give early warning in a short time. The fourth is strong survivability. The satellite platform equipped with the "God's Staff" is usually in the orbit of 1000 kilometers from the ground, far beyond the attack range of general aircraft and missiles. Fifth, environmental pollution is small. The "God's Staff" mainly attacks targets through collisions, does not depend on ammunition, and does not have nuclear radiation, and will not cause pollution to the environment. The sixth is to occupy morality and take the initiative. Compared to nuclear weapons, the weapon system has more moral authority.
Long Hanging Sword
In order to compete for space hegemony, the United States has once proposed the "sky-based laser weapons" plan, the "smart pebble" plan, the "mirror mirror" space-based laser weapons program, etc., but the progress has been slow due to new breakthroughs in key technologies. Even died in the middle. With the rapid development of technologies such as aerospace, thermal materials, and computers, some problems may have been solved since the "God's Staff" was developed. However, there are still many bottlenecks that cannot be achieved. One is how to launch into place. Launching a satellite platform carrying a lot of high quality "God's Staff" will inevitably require sufficient power. The second problem is high temperature loss. After entering the atmosphere, the problem of overheating of the projectile due to air friction will inevitably occur. Overheating of the projectile will directly lead to damage to the internal precision electronic components, wear or disintegration of the projectile. The third issue is precision guidance. Because of its use of terminal guidance, it usually achieves a precise strike on the target by controlling the attitude angle before entering the atmosphere. However, after entering the atmosphere, the projectile will inevitably be affected by many uncertain factors such as air flow, density differences, and the speed is too fast. Without tail modification, it is difficult to achieve a precise blow to the target.
In addition, the effect of "God's Staff" is unknown. As no simulations have ever been conducted, the US military's description of the attacking effect is merely a theoretical assumption. Some experts predict that due to its excessive speed, it is likely to have no fatal effect on targets such as large buildings. At most, it is like a bullet flying at high speed and hitting a glass with a diameter of 30 cm. If this is the case, it would be a laughing stock. However, for the "God's Staff" plan, the biggest problem at present is probably high development costs. The cost of a satellite platform needed to build the "God's Staff" and putting it into orbit was alleged to be at least $1 billion; if a high-quality metal rod were to be put into orbit using today's space transportation system, the cost would be even more. Astronomical numbers.
Therefore, some experts believe that the "God's Staff" of the US military looks like an artifact and is actually a chicken rib. Judging from the current slow progress, the U.S. military may fall into the "research" with no "costs" and discard the pity. It will eventually enter the actual combat, show its glory, or be eliminated by the cruel rules of war like the "Paris Artillery", or it will only stay in the imaginary virtual world. We will wait and see. (Li Xuguang)
