The United States Space Force has created a new program to develop space-based missile interceptors, with the goal of being able to demonstrate their capability within two years.
The U.S. Space Force established the Space-Based Interceptor (SBI) program in order to develop a constellation of spacecraft that can defend the United States against "a new generation of threats" such as hypersonic weapons, neutralizing them while in flight. The program is part of the planned Golden Dome for America defense system announced by President Trump last year. Estimates of the system's price tag range wildly, from the White House's projected $175 billion to as high as $3.6 trillion.
