The Pentagon's proposed Golden Dome missile defense system will feature a four-layer architecture, combining satellite-based sensors with three land-based components, according to slides presented to defense contractors. The plan includes 11 short-range missile batteries positioned across the continental United States, Alaska, and Hawaii, as well as a new large missile field in the Midwest for advanced interceptors. While the system draws inspiration from Israel's Iron Dome, it is designed to be much larger and more complex, aiming to protect against a wide array of threats. Technical challenges remain, including communication latency and uncertainties about the number of launchers, interceptors, and ground stations required. The project is still in its early stages, with a 2028 deadline and significant funding already allocated, but many details are yet to be finalized.
