How will America’s ‘Game Changer’ Golden Dom Defense System work?

US President Donald Trump on May 20, 2025, announced a plan to create a defense system called ‘Gold Dome’ or ‘Golden Dome’, which aims to protect the United States from ballistic, cruise, hypertensive missiles and space -fired missiles.

President Trump said the ‘game changer’ project would be fully functional before the end of his three -year rule and would provide about 100 % protection to the United States. He said the work was started by President Reagan in the 1980s and he was completing it.

According to the president, the system will cost $ 175 billion, however, the Congressional Budget Office says the actual cost will be around $ 542 billion.

Obviously, the United States is the only country that can afford this kind of expenditure as its current annual budget is about $ 1,000 billion. China is about $ 300 billion and Russia is far behind the United States in terms of defense budget of $ 100 billion.

President Trump said: ‘Once the Golden Dome is fully built, it will be able to stop the missiles, whether they are fired from the other corner of the world or whether it is from space. We will have the best system so far. ‘

Why does the United States need a missile shield?

There are already missile prevention systems such as the Patriot and National Advanced Surface Two Air Missile System in the United States, but US military experts say this expensive system is needed that many countries, including China, Russia, North Korea and India, have developed such missiles in the past few years.

These weapons include modern ballistic and cruise missiles, as well as new long -range hypertensive missiles, which the United States considers to be a threat to itself.

Hyper Sonic Missile is one, with a speed of at least five times higher than sound speed, ie 6175 km per hour or mac 5.

In 2019, Russia announced that it had developed a missile that has a speed of 27 times more than the sound.

Hypersonic missiles against ballistic missiles can also change their way in search of their target.

Russia has fired hypertensive missiles against Ukraine in the ongoing war. In addition, China has developed the latest hypersonic missiles, so the United States needs a new defense system.

How does a country’s missile defense system work?

There are several parts of the missile defense system. The first is the sensors or radars that identify it immediately after the missile was fired.

For this purpose, it is necessary to install these sensors in areas where the risk of firing missiles is the highest. The United States will try to install its missiles around China, Russia and North Korea.

After that, a system of sensors spread around the world is essential, to explain what the missile will pass through and most importantly, what is its destination.

Since the United States is not regional but international power and its interests are spreading all over the continents, the potential threats it faces is related to different regions of the world, so these sensors can spread worldwide. These sensors will be present not only on the ground but also in the sea and in space, and China has objected to the same part.

Third, interceptors come. These may be defensive missiles that destroy enemy missiles on the way.

The United States already has a wide network of sensors and interceptors around the world and space, but they were mainly made from a view of safety from ballistic missiles. The United States will have to upgrade this system and need more space sensors to detect hypertensic missiles.

Second, interceptors also need to improve so that they can stop hypersonic and other missiles and warheads that change the way. These interprings will have to make the United States a worldwide platform. These platforms can be a dynamic platform in different US areas, in friendly countries or in ships.

How will this system be created?

The Golden Dome will not be a system but a combination of three types of systems. The first step would be to identify the enemy’s missile. Second, the missiles should be tracked all over its way as the hyper -sonic missiles are capable of changing the way. Third, there is an interceptor missile system, which destroys the atmosphere before reaching its target near the enemy missile.

The biggest challenge is the ability to track the Hyper Sonic missiles. This requires new types of sensors and various platforms that can track all stages of Hyper Sonic missile flight. The Golden Dome Sensors will be installed on various platforms under a basement system, including earth, sea, air and space.

These platforms will be equipped with a variety of sensors that are specifically designed to track hypertensive risks at different stages. These defense systems will also be designed to prevent space -fired weapons. Infrastructure will be mostly multi -faceted so that it can be effective to defend a variety of missiles.

How effective will this system be?

Israel’s Iron Dome system is considered the most effective in the world, but it is not 100 % effective, and occasionally Hamas and other militant organizations are messing up with a lot of cheap missiles and rockets, so it is not possible for a missile defense system to ever provide 100 % protection.

The main purpose here is to prevent, such as the prevention of nuclear weapons against the Soviet Union in the Cold War. All the weapons defending against the Golden Dome are very expensive. The United States is trying to change the thinking of opponents to the extent that they refrain from flickering their valuable missiles on the United States because they are more likely to fail their missiles.

Can this system be developed in three years?

President Trump has indicated that the system will be active by 2029. Experts say the duration is very low and by then it is difficult to activate such a large system.

But on the other hand, many countries have hypersonic missiles from now on, so the United States believes it needs to work on an emergency basis, so the United States may try to complete more resources and complete it as soon as possible.

Why does China object to this system?

China expressed strong reservations on the system on May 21 that the US plan is taking aggressive ambitions and will increase the race to use space for military purposes.

Chinese Foreign Ministry spokesman Mao Ning said China urges the United States to stop working on the system as soon as possible.

In a briefing in Beijing on Wednesday, he said that the Golden Dom ‘is a violation of the principle that the security of all countries should not be jeopardized and weaken the global strategic balance and stability. China expresses serious concern over it. ‘

How different is the Golden Dome from Israel’s Iron Dome?

Iron Dome was developed by Israeli defense company Rafael (not belonging to the French aircraft Rafal) in 2011, while the United States also invested heavily. The system is capable of destroying rockets and missiles fired from four kilometers to 70 km.

Rafael claims that the success rate of the Iron Dome system is more than 90 %, but other experts say the actual rate is close to 80 %. Several missiles fired by Hamas fell on Israeli areas, which could not stop the system.

The Golden Dome is several times larger, modern and expensive than the Iron Dome. Israel is a small country that often faces low -cost missiles, while the United States is a major country and is threatened by intercontinental hypersonic missiles.

Golden Dom vs. S400

Recently, India’s defense system S400 was particularly discussed in the four -day war between Pakistan and India. The land -hitting system is a Russian -developed missile, which has been used by Russia since 2007. It has been developed by the Russian defense agency Almaz Central Design Bureau, which has been working on this system since 1993. It is capable of hitting 400 km away and is an alternative to the American Patriot missile system.

Earlier, Russia has built the S2 and S300, thus the S400 can be called the fourth generation of the missile system and can be used against all kinds of air strikes, including aircraft, drones, cruise missiles and ballistic missiles.

The missile system can take action against air strikes from 250 km to 400 km. The system has five types of missiles that are capable of firing according to the nature of the target.

Russia has previously sold the missile system to China and Turkey. India had purchased the system worth $ 5.43 billion under an agreement with Russia in 2018 and all missiles will be provided by 2023.

China already has this missile system, and interestingly, it has installed two systems near the Indian states of Ladakh and Arunachal Pradesh, while a system has been planted near Taiwan.

In terms of range, the S400 has the lead on the Iron Dome, as the Iron Dome is capable of countering all kinds of air risk, including the S400 aircraft, while the Iron Dome is only effective against rockets and missiles.

Thod missile system

According to the newspaper Financial Express, S400 has the lead on the US missile system in the sense that the Thad is fitted in one place while the S400 is installed on heavy duty 8 by 8 trucks, which can be driven to any area. Since this whole system is mobile, it cannot be easily targeted by the enemy during the war period and can be moved from one place to another due to danger.

In comparison, the US thread system is effective only against long -hitting missiles and does not work against enemy warplanes, besides close -fire missiles.

Moreover, the thread range is also half compared to the S400, ie 150 to 200 km.

Another difference is that Thad can only fire a type of missile, while S400 has several types of missiles, which can be used in terms of target nature.

Patriot missile system

The Patriot range is also limited to the Thad and can launch the missile for only 100 km away.

In recent years, the Patriot system has been questioning the effectiveness and performance of the system. In 1991, the United States used the Patriot system in the war against Iraq and claimed that it destroyed 45 of the 47 missiles fired by Iraq before it collapsed.

However, the US military later acknowledged that the system’s performance was only 50 %.

Gold is the favorite metal of President Trump and he has used his ship and in his home. Therefore, they want to provide a defense system to the United States with the help of this name that they can inherit.
