Donald Trump’s missile defence plan, called the Golden Dome, is set to become one of the most expensive military projects in U.S. history. Let’s take a look at how it has become a reason of rivalry, between Silicon Valley’s tech disruptors and America’s traditional defence giants.

It’s not just a missile shield. It’s a new industrial war.
And the battlefield is the Pentagon’s budget.

The Golden Dome is Donald Trump’s answer to the next generation of missile threats.
It’s designed to detect and destroy missiles from space, using satellites, sensors, and laser interceptors.
The goal is speed: stop an attack in seconds, before it hits American soil.

Inspired by Israel’s Iron Dome, this version would cover the entire globe.
And the threats? Hypersonic missiles from countries, weapons that travel faster than sound and evade traditional defences.

But it’s not just what the system does, it’s who builds it.

Trump’s order opened the door to non-traditional defence players. Tech companies. Start-ups. Venture-backed AI labs.
Now, names like Microsoft, Palantir, and C3 AI are bidding against Lockheed Martin and Northrop Grumman — the two pillars of America’s defence industry.

According to The Financial Times, over 500 companies have already responded. The Missile Defense Agency is preparing to award $151 billion across ten-year contracts.

Legacy players promise reliability. They pitch proven systems already in use — interceptors, radar, satellites.
But tech firms bring speed, scale, and AI-powered tools that legacy firms are still catching up to.

There’s friction. SpaceX was once expected to play a key role, until Elon Musk’s public fallout with Trump threw its status into question.

Start-ups like Anduril, Epirus, and Shield AI are now valued over $1 billion each — but they still lack the battlefield record of traditional defence contractors.
And while their software is advanced, critics warn that real-world performance remains unproven.

Investors have poured over $150 billion into defence tech since 2021. But most of the Pentagon’s money still flows to the established players.

The Pentagon says it needs both. Old capability and new code.
But in the end, only one side will lead the future of warfare.
