🎉✈️ Happy 78th Birthday to the United States Air Force! 🎉✈️ On September 18, 1947, the Air Force officially became its own branch of the U.S. Armed Forces under the National Security Act, separating from the Army and soaring into a new era of air, space, and cyber dominance. Guided by its mission “to fly, fight, and win – airpower anytime, anywhere,” the Air Force continues to uphold and defend the Constitution with unwavering resolve. Today, we honor their service, sacrifice, and 78 years of excellence. 🇺🇸 #USAirForce #AirForce #UnitedStates #Military #Huzzah #OldIronsides #USNavy #LivingHistory #ussconstitution #AmericasNavy250 #Thunderbirds
