The first head boils outside the Earth’s atmosphere. Faster absent missiles in cruise fall into American infrastructure. Newclear explosions with the sky.
These are just some of the night scenarios, which experts have warned that limited defense systems are overwhelmed in the future high-tech attack.
Even a relatively small nuclear detonation of hundreds of miles above the head of Americans would create an electromagnetic pulse – or EMP – which would have apocalyptic results. The planes would fall from the sky across the country. Everything from manual electronics and medical devices to the water systems would be completely useless.
“We wouldn’t go back for 100 years,” William Fortschen said, author and weapons researcher at Montreat College in North Carolina. “We would lose everything and we don’t know how to rebuild it. It would be equivalent to us return 1,000 years and start starting from zero.”
In response to these hypothetical – but experts say that they are quite possible – threats, American President Donald Trump set eyes to the “Next Generation” rocket shield: Golden dome.
But while many experts agree that the construction of such a system is necessary, its high and logistical complexity will make Trump Mission to strengthen American missile defenses extremely challenging.
The executive order calls for what he initially called “Iron Dome for America” noted that the threat of weapons for the next generation “became more intense and most affordable”, potentially “catastrophic” scenario for the United States.
Patricja Basilczik, a rocket defense expert in the Višina DC-seats of the Center for Strategic and International Studies, said the BBC to make existing systems focused on intercontinental ballistic rockets or ICBMS, such as those used by North Korea. But powerful nations like Russia and China also invest in newer technologies that could only hit neighbors, but also opponents of the ocean.
Among the threats that are publicly identified by US defense officials are hypersonic weapon is able to move faster than sound speed And bombing systems fractional orbital bombing – called FOBs – which could deliver hospitals from space.
Each – even in limited numbers – are deadly.
“Golden dome Reverive policy Our missile defense towards our great strength competitors,” Ms. Basilczik said. “Our opponents invest in the possibility of a long string strike, including things that are not your typical rockets we are dealing with for years.”

What will “golden dome” look like?
So far, the White House and Defense officials have so far provided several specific details about what the golden dome – which is still in their conceptual phases – would actually look like.
Speak with a trump in the Oval Office’s Oval Office, the Secretary of Defense of Pete Hegseth has only said that the system will have more layers “through the country, sea and space, including sensors based on space and intercepts”.
Trump added that the system will be able to intercept missiles “even if they are launched from other sides of the world, and even if they are launched in space,” Florida and Alaska based various aspects.
In previous testimony in Congress, the newly received program supervisor, General Michael Guetlein, said that the golden dome would build on existing systems that are largely directed at traditional ICBMS. The new system would – add more layers that could also detect from cruise missiles and other threats, including intercepted before they launched or at different phases of flight.
The current American Rocket Defense Agency relies heavily on 44 ground floor intercepters based in Alaska and California, designed to fight a limited rocket.
Experts warned that the existing system is inadequate if the American homeland must attack Russia and China, each of which has an extended arsenal of hundreds of ICBMS and thousands of cruise missiles.
“(Current systems) were created for North Korea,” said Dr. Stacie Pettijohn, a defense expert in the National Security Center. “It could never intercept a large arsenal like Russia, or even much smaller like China.”
The Congress Research Office, or CBO, said “hundreds or thousands” platforms based on the universe will need to “provide even minimal defense” against incoming missiles – a potentially huge set of proposals.
Israeli iron domes: example?
Trump first discovered his concept for a golden dome during the joint address of Congress in March, when he said that “Israel has it, there are other places and the United States should and”.
The president thought of Israeli system “Iron domes”Which country used to intercept rockets and projectiles since 2011. years.
Israel’s iron domes, however, is designed to intercept the threats to a shorter range, while two more systems known as David’s monitoring and arrows, fight major ballistic missiles, such as those who fired Iran and Hotis in Yemen.
Ms. Basilczik described an iron dome as directed on the threats “lower layers”, like a rocket fired from Gaza or South Lebanon.
The golden dome would cross it, to detect longer reach rockets, she said.
In order to achieve this, she said it would have to combine different possibilities.
“And I will look forward to the commander and the control system that can relax all this,” she said, noted that something like that currently did not exist.

Can it do that?
Creating that system will be incredibly complicated – and expensive – proposal.
At the Trump’s Oval Office, he could be completed by the gold domes to the end of his mandate, with the total cost of $ 175 billion, including a 25 billion dollar investment for him already intended for him.
Its assessment is far from synchronization with CBO, which put a potential price at $ 542 billion over 20 years only on space systems. Experts said that the total costs could eventually abolish a large piece of mass defense budget.
“I think it’s unrealistic,” Dr Pettijohn said. “This is complicated, with multiple systems to be integrated together. Each of these steps has its own risks, costs and schedules.”
“And it will go quickly add more costs and risks,” she added. “You will probably produce something that will not be so detailed … in us will be resurrected on the road and what you produce may need big overhaul.”
The creation of gold domes also caused fears that this could lead to new “arms races”, with us enemies that direct their own efforts to find ways to overcome or bypassed his defense.
The Chinese Ministry of Foreign Affairs Mao Ning, for example, told reporters that the plan “reinforced the risk of space becomes a battlefield”.
Those involved in the research of the worst scenarios and American defense policies reduced these problems. Potential enemies, they claim, but bring pleasant offensive opportunities.
“The golden dome aims to change the strategic budget of our opponents,” Ms. Basilczik said. “Improving the homeland of air and projectile reduces the trust of a potential attacker in achieving any goals that are looking for.”
“He raises a threshold for them to get involved in this attack,” she added. “And that contributes to overall deterrence.”
Even partially ended the golden dome, he said, Mr. Fortschen, could prevent the nightmary scenario to hold.
“I’ll breathe a lot of relief,” he said. “We need that kind of system. The golden dome is the answer.”
