HB 1989 updates Tennessee's legal references to recognize the U.S. Space Force as a distinct military branch. It amends 15 Tennessee Code sections to add "space force" alongside existing branches (army, navy, air force, etc.) in definitions covering military personnel, benefits, and service-related provisions. This change directly affects how Tennessee law references military service members, including their spouses, dependents, and eligibility for state programs like vehicle registration reciprocity. The bill makes no new policy changes but aligns state statutes with the federal establishment of the Space Force.
