Morphology

air + force

The meaning 'branch of the military that conducts operations in the air' is directly and compositionally derived from 'air' (relating to aviation) + 'force' (a trained military group). This is a productive noun-noun compound with clear cross-linguistic parallels (e.g. French 'armée de l'air', Spanish 'fuerza aérea'), so a B1 learner who knows both constituents would readily infer the MWE's meaning.

Etymology

Air force comes from the words air (the sky) and force (a group of soldiers). When countries put planes together as a military group to 'fight from the sky', they called that group an air force, so today it means the part of the military that operates in the air.
