US' Golden Dome shield to detect, counter threats with space‑based tech

The United States has increased the projected cost of its “Golden Dome” missile defense program to around $185 billion, reflecting a $10 billion rise from earlier estimates. This increase is driven by efforts to accelerate the development and deployment of advanced space-based tracking and communication systems. Golden Dome is envisioned as a comprehensive, multi-layered defense shield designed to detect and intercept a broad spectrum of missile threats, including ballistic, cruise, and hypersonic missiles. Central to the program is the integration of space-based sensors and infrastructure, which will enable earlier threat detection and enhanced coordination across defense systems. Key components funded by the expanded budget include new satellite constellations, data-sharing networks, and advanced tracking technologies such as the Hypersonic and Ballistic Tracking Space Sensor (HBTSS). These technologies are critical for countering emerging missile threats that travel at high speeds and are difficult to detect with traditional systems. Leading defense contractors like Lockheed Martin, RTX, and Northrop Grumman are heavily involved in
