Ronald Reagan released the U.S. military’s “Star Wars” project back in the 1980s, profoundly revolutionizing military thinking. In June of 2025, the U.S. military strikes back with its sequel to the 1980s Strategic Defense Initiative (SDI).
At the 2025 Paris Air Show, defense giants Lockheed Martin and Boeing revealed their bids to lead the “Golden Dome.” This $175 billion U.S. initiative announced by President Trump sets out to build a multi-layered, constellation-like defense network. Similar to the ambitious, cancelled projects from the ‘80s, U.S. defense manufacturers are setting out to fill Low Earth Orbit (LEO) with satellites that have space-based interceptors.
The Golden Dome envisions hundreds of satellites equipped with interceptors to detect, track, and eliminate incoming missiles. Hypersonic missiles are the newest and most dangerous military development in recent history; this satellite initiative would bring the U.S. one step closer to being on top of hypersonic missile defense.
Explicitly aimed at maintaining weapons in Earth’s orbit to neutralize missiles, the project represents a significant shift in the missile defense industry. In America, the defense industry could be undergoing its first major change in years: a change focused on space-based defense systems.
Lockheed and Boeing aren’t the only major players behind this new shift. SpaceX, Palantir, and Andurill are also actively involved in early bids. Specifically, SpaceX envisions launching their Starshield satellite to track incoming threats. Lockheed Martin openly admitted willingness to collaborate with competitors—signalling a hybrid consortium structure across defense firms.
Critics, including space policy experts and politicians, argue the project is overly-ambitious. Warnings of unchecked spending are causing partisan conflict. While Trump cites the initiative will cost approximately $175 billion through 2029, the Congressional Budget Office (CBO) estimated the project could cost anywhere between $161 billion and $542 billion.
The SDI was proposed amongst tensions between the U.S. and the USSR, eventually leading to the USSR accelerating their own missile defense initiatives. This new Golden Dome project could provoke Russia and China to deploy their own space-based missile defense systems, just as the Star Wars project did.
China and Russia will likely interpret the Golden Dome as an attempt to undermine their own missile defense efforts. Hypersonic missiles are the pillar of the modern missile defense industry—the Golden Dome directly targets this.
The ambitious proposal raises many questions and uncertainties. Questions of technical uncertainties, political uncertainties, and international repercussions. In a sea of uncertainty, one must ask if this will work, or if it will simply crush under its own weight.
