The system will combine terrestrial, naval, airborne, and space-based sensors and interceptors, along with non-kinetic defenses like directed energy weapons and electronic warfare capabilities. Saltzman emphasized that decision-making is still in early stages.

Instead of waiting 17 years for a traditional rollout, the Pentagon is fast-tracking development with space-based interceptors and infrared satellites. The focus is on what can we do in the next two to four years. It could potentially cost tens of billions of dollars over the next decade, depending on its final scope.

The Golden Dome initiative aims to create a comprehensive shield protecting the United States against an array of missile threats, including ballistic, hypersonic and advanced cruise missiles. The system's core components would include space-based sensors and missile interceptors, utilizing orbital vantage points for early detection and rapid response.

SpaceX Proposes 1000+ Satellites for Tracking and Attack Satellites

SpaceX has proposed subscription-based model where the government would pay for access to the satellite network rather than owning the hardware outright. This approach represents a departure from traditional defense procurement methods and has generated both interest and concern within the Pentagon.

A SpaceX-led partnership has emerged as a leading contender. SpaceX contributes its considerable satellite launch and Starshield mass production of satellites and Palantir provides data analytics and software expertise, and Anduril bringing autonomous defense and drone technology. Their proposal includes 400 to over 1,000 satellites for global missile detection and tracking, complemented by approximately 200 "attack satellites" equipped with missiles or lasers that would aim to neutralize threats.

Pentagon Planning

The Pentagon has been directed to develop an "architecture" for this missile defense shield — essentially designing the structure of the network, how its components will be organized, and how they will interact with each other.

Saltzman said this work remains in early stages. "We're nowhere near" finalizing an architecture, he said. "We're doing the planning. We're looking at what resources might be available, which programs are currently developed that might contribute to it. And that is all still way pre-decisional."
