The United States Air Force has a rich history, and its Latin motto, "Molinari Desiderium" or more commonly known as "Fly, Fight, Win," is not actually in Latin, but the core values of the Air Force are represented by the phrase "Integrity First, Service Before Self, and Excellence in All We Do." However, each unit within the Air Force has its own distinct motto, often in Latin, reflecting the unit's specific values and traditions. One of the most recognized Latin mottos associated with the Air Force is "Per Ardua ad Astra," which translates to "Through Adversity to the Stars." This motto is not exclusive to the US Air Force, as it is also used by the Royal Air Force (RAF) of the United Kingdom.
History and Significance of Air Force Mottos

The use of Latin mottos by military units, including those in the Air Force, is a tradition that dates back centuries. These mottos serve as a way to encapsulate the mission, values, and history of a unit in a few, carefully chosen words. “Per Ardua ad Astra” is particularly significant as it symbolizes the perseverance and ambition required to overcome challenges and reach for excellence, which are core to the ethos of air forces around the world. The motto reminds airmen of the importance of striving for excellence, even in the face of adversity, and the pursuit of innovation and progress.
Latin Mottos in the Air Force
Beyond “Per Ardua ad Astra,” many Air Force units have their own Latin mottos that reflect their unique histories and specialties. For example, the 1st Fighter Wing’s motto is “Aut Vincere Aut Mors,” which translates to “Either to Conquer or to Die,” emphasizing the wing’s commitment to victory and the ultimate sacrifice. These mottos are not merely ceremonial; they are integral to the identity and morale of the units, serving as a constant reminder of their purpose and the values they uphold.
