Morphology

united + state + air + force

The phrase is fully compositional: 'United States' denotes the nation and 'Air Force' denotes a military branch for aviation, so a learner who knows these constituents can infer it refers to the US military branch responsible for air (and related) operations. It is a literal institutional name rather than an idiom, and similar constructions exist in many languages, making it readily understandable.

Etymology

United States Air Force comes from when the United States created a new military service after World War II just for fighting in the air and later in space. Before that, pilots were part of the Army, so the new name shows it is the US 'service' for air power, and that is why it means 'the military branch that fights in the air and space'.
