The Space Force Birthday marks the establishment of the United States Space Force on December 20, 2019. As the newest branch of the Armed Forces, the Space Force was created to organize, train, and equip guardians to protect American interests in space and to ensure the security of space operations vital to our nation’s defense and daily life.

This day is on the calendar to recognize the growing importance of space in national security and to honor the men and women who serve in this pioneering force. The Space Force reflects the evolving landscape of modern warfare and the critical need to safeguard satellites, communications systems, and space-based technologies that support both military and civilian life.

Celebrating the Space Force Birthday is not only about recognizing innovation and progress but also about acknowledging the dedication of those who are shaping the future of defense. It is a time to support this bold mission and to honor the guardians who stand watch beyond our skies.
