The Space National Guard Establishment Act of 2025 aims to create a dedicated branch of the National Guard focused on space operations, known as the Space National Guard. This new entity will serve as a reserve component of the Space Force, which is responsible for military operations in space, thereby enhancing the United States' capabilities in space defense and operations. The legislation establishes the Space National Guard, which will be composed of existing units from various states including Alaska, California, Colorado, Florida, Hawaii, New York, and Ohio.
