The Space Force Delta is the official logo of the U.S. Space Force, the space warfare service branch of the U.S. Armed Forces. The delta itself was unveiled on 22 July 2020.



The Delta Symbol - An Origin Story

The Space Force Delta was officially unveiled by the Senior Enlisted Advisor of the Space Force, CMSgt Roger A. Towberman on 22 July 2020, alongside the Space Force's motto Semper Supra, which translates to "Always Above". The delta symbol has a strong historical tradition in the Space Force, being first used by military space units in 1961 and also being used to identify the second highest echelon of Space Force units, as well as holding a central position in the Space Operations Badge, Space Force seal, and Space Force flag.[2][3]

The seal and delta 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 logo from Air Force Space Command, rather than the other way around.[4]
