The Space Force seal is on a dark blue disc, between two constellations in white, a light blue globe grid-lined in silver surmounted by a silver delta both encircled diagonally by a white orbit ring, all beneath a white Northern star in the upper left portion of the disc and above the Roman numerals "MMXIX" arching in white below. Encircling the disc is a dark blue designation band edged with an inner and outer border and between two deltas, the inscription "UNITED STATES SPACE FORCE" at top and "DEPARTMENT OF THE AIR FORCE" at bottom, all in white.
The delta wing evokes historic ties to the earliest days of the U.S. Air Forcespace community, and symbolizes change and innovation. It also represents all variations of space vehicles that support the National Defense Strategy and National Security Space Strategy. Dark and lightshades of grey within the delta embody the 24/7 operations of the Space Force, while the placement and upward orientation of the delta reveals the central role of the Space Force in defending the space domain.
The elliptical orbit around the globe signifies defense and protection from all adversaries and threats emanating from the space domain. It also represents ongoing interagency cooperation and allied partnerships.
The white Polaris symbolizes the guiding light of security and alludes to a constant presence and vigilance in space now and in the future.
Two clusters of small stars represent the space assets developed, maintained, and operated by the U.S. Space Force.
The three larger stars symbolize the Organize, Train, and Equip functions of the Space Force.
History
The Seal of the United States Space Force was first approved on 15 January 2020, and was officially revealed on 24 January 2020. The seal quickly gained social media notoriety, as individuals compared it to the seal of Starfleet; however, the Space Force refuted the notion, stating that the central delta insignia was first used in 1942 by the United States Army Air Forces, and then adopted by the Air Force's early space program in 1961, years before Star Trek debuted in 1966. A number of military commentators noted that it was likely that Star Trek derived its symbolism from Air Force Space Command, rather than the other way around.
