President Trump speaks alongside Secretary of Protection Pete Hegseth within the Oval Workplace on Could 20, 2025, saying plans for the “Golden Dome,” a nationwide ballistic and cruise missile protection system.

President Trump on Tuesday unveiled an bold plan to defend America from missile assault by constructing what he describes as a “Golden Dome.”
“As soon as absolutely constructed the Golden Dome might be able to intercepting missiles even when they’re launched from different sides of the world and even when they’re launched from house,” Trump instructed reporters within the Oval Workplace.
Trump’s funds and timeline for the venture are bold. He instructed reporters he hoped to have it completed “earlier than the tip of my time period.” The system would value round $175 billion, the president stated, with $25 billion to begin development in subsequent yr’s funds.
A key a part of the Trump plan is to put each missile-sensing and missile-destroying satellites into orbit above the Earth. The constellation would possible contain 1000’s of small satellites able to attacking a missile within the moments after it launches from its submarine or silo.
Such an unlimited community of satellites would have been unthinkable just some years in the past, however it now appears not less than theoretically inside attain. Elon Musk’s firm SpaceX has been utilizing low-cost rockets to launch a constellation of internet-transmitting satellites referred to as Starlink. SpaceX says the Starlink system at the moment has round 7,000 satellites in orbit, a scale that’s corresponding to most estimates of what a restricted space-based missile protection functionality would require.
“The general Golden Dome effort is lengthy overdue,” says Tom Karako, director of the missile protection venture on the Middle for Strategic and Worldwide Research. Karako concedes that space-based interception of incoming missiles is a “depraved laborious downside,” however he says the truth is that the subsequent giant warfare will possible be fought partially above Earth’s environment. Provided that actuality, he thinks Golden Dome’s capabilities will present the U.S. with a strong protection that may be used for anti-satellite warfare if wanted.
“There is a have to take care of a complete lot of issues which can be in house and going by means of house,” he says.
Area-based missile protection has been a dream of politicians for many years. In 1983, Ronald Reagan announced plans for a system to intercept missiles from the then-Soviet Union.
“I do know it is a formidable job, one which is probably not completed earlier than the tip of this century,” Reagan stated on the time. “It would take years, in all probability many years of effort on many fronts.”
In the long run, the Soviet Union collapsed earlier than something approaching Reagan’s imaginative and prescient may very well be realized, however missile defenses have progressed. U.S. Patriot missiles have labored for many years to intercept shorter-range missiles, and the U.S. now has a number of techniques able to intercepting medium- and intermediate-range ballistic missiles. It additionally has a small variety of interceptors able to hitting ICBMs throughout the center of their flight. That functionality is aimed squarely at nuclear upstart North Korea.
Different international locations, specifically Israel and Ukraine, have used missile defenses to guard themselves from assault lately.
The U.S. army has ground- and sea-based missile protection techniques. The Golden Dome would increase their attain into house.

However intercepting Intercontinental Ballistic Missiles in giant numbers stays a much more troublesome downside. ICBMs launch from deep inside enemy territory and scream again to Earth at hypersonic speeds, making them practically unimaginable to hit on the finish of their flight. They will additionally deploy decoys that may idiot interceptors. One of the best time to hit them is as they’re simply launching from their silos, however doing so requires an especially fast response by space-based interceptors. Hundreds of interceptors have to be launched with a view to be certain that one is passing above a missile when it launches.
Whether or not the expertise has, in truth, arrived is way from clear.
An orbital system can be advanced, pricey and finally weak to counterattack, warns Laura Grego, a physicist on the Union of Involved Scientists, a bunch skeptical of missile protection improvement. Grego says {that a} community like Golden Dome may very well be defeated by clustering launches to overwhelm the system, or by attacking the satellites themselves. The U.S. has not too long ago accused Russia of finding out find out how to place nuclear warheads in orbit. Such a warhead may knock out giant sections of any Golden Dome system in house.
And the threats dealing with the U.S. are extra various than ever. A recent report from the Protection Intelligence Company confirmed that Golden Dome would additionally should take care of new and rising threats like cruise missiles, hypersonic missiles that may skim the sting of house and weapons referred to as Fractional Orbital Bombardment Methods, which might launch, glide by means of a part of an orbit across the Earth after which assault from any route.
The general value of Golden Dome is way from sure. Whereas the president says it may very well be completed for $175 billion over three years, a recent estimate from the Congressional Price range Workplace put the associated fee at between $161-$542 billion over 20 years. Individually, Sen. Tim Sheehy, R-Mont., who’s heading a “Golden Dome caucus,” not too long ago instructed a crowd that, “It would possible value within the trillions if and when Golden Dome is accomplished,” according to Area Information.
Given the potential excessive prices, Grego hopes that Congress will take a cautious look earlier than giving the Trump administration cash to pursue the system. The street to missile protection “is affected by applications that had been began and deserted after some variety of years,” Grego says. “I might say ask the laborious questions at the start, earlier than you go down this street.”
