Golden Dome: A Defining Challenge for Defense Technology Innovators

Leaders in the military technology sector, from Silicon Valley and beyond, are highly confident in their ability to deliver unprecedented capabilities at lower costs than traditional defense giants like Lockheed Martin and RTX. This confidence is supported by examples such as SpaceX’s emergence as the primary provider of space launch services for the U.S. military, displacing Boeing and Lockheed Martin, and the potential for drones to offer cost-effective air combat alternatives to complex piloted aircraft like the F-35.

Palmer Luckey, founder of Anduril, extended this optimism significantly in a CNBC interview, suggesting that by eliminating wasteful spending, the U.S. could be defended with a $500 billion annual Pentagon budget—half of current levels and one-third of the Trump administration’s latest request. He stated precisely: “We need to get our act together so that we can get everything that currently costs $1.5 trillion for well under a trillion dollars. I would love to see a sub-500 billion defense budget if it’s getting us the things that we need.”

While this may be true, achieving such a significant reduction would necessitate more than just trimming the weapons budget. It would involve downsizing the armed forces and adopting a more pragmatic strategy that does not assume the U.S. can intervene globally at a moment’s notice.

Luckey proposes one solution: increasing support for allies to defend themselves. However, this approach demands careful selection of partners to prevent enabling conflicts such as Saudi Arabia’s harsh war in Yemen or Israel’s widespread actions in Gaza.

Setting aside these broader strategic issues, a key example of questionable weapons is President Trump’s proposed Golden Dome missile defense system—specifically, the version promising an impenetrable shield against all missile types, with space-based interceptors as a central component.

The aspiration for a leak-proof missile defense dates back to President Ronald Reagan’s 1983 “Star Wars” speech. After more than 40 years and $350 billion in expenditures, missile defense programs have fallen far short of this objective, with no test adequately simulating a real attack by numerous long-range nuclear missiles.

The challenge lies in the speed of incoming warheads—up to 15,000 miles per hour—and in space, decoys like coated balloons can mimic real warheads. A massive attack with hundreds of missiles, each with multiple warheads and decoys, could easily saturate any defense. According to Taxpayers for Common Sense, achieving a leak-proof defense might require up to 1,600 interceptors per warhead. Moreover, the American Enterprise Institute estimates that a comprehensive Golden Dome could cost as much as $3.6 trillion over time.

Beyond the exorbitant cost and slim chances of success, deploying space-based interceptors for Golden Dome is perilously ill-advised. Although intercepting a high-speed warhead is difficult, satellites in predictable orbits are vulnerable targets. Historically, even during the Cold War, norms prohibited weaponizing space to protect satellite infrastructure. Abandoning this norm now would jeopardize civilian and military satellite operations, a steep cost for a system unlikely to achieve its lofty goals.

These realities present a moral and practical quandary for defense companies, especially military tech firms. Should they openly address the difficulties of creating a leak-proof missile defense and advocate for a more affordable, feasible solution? Or remain silent on the administration’s unrealistic aims and accept funding based on them? It’s not solely the responsibility of defense executives to bring pragmatism to the Golden Dome discussion—scientists, Congress members, Pentagon analysts, the media, and the public must all critically evaluate the claims. However, the tech sector leaders who could profit from Golden Dome spending, regardless of its effectiveness, hold significant influence.
