空军

空军 (kōng jūn) refers to the aerial military force of a country, responsible for defending the nation's airspace and conducting air operations. It is distinct from the army and navy, focusing specifically on air-based combat and defense.

The character 空 (kōng) means 'sky' or 'air,' while 军 (jūn) means 'army' or 'military.' Together, they literally translate to 'sky army,' emphasizing the branch's focus on air superiority and aerial warfare.

空军 is commonly used in both formal and informal contexts, such as discussing national defense, military strategies, or historical events involving air forces. It is also used in media and education to describe the role of air power in modern warfare.
