What is known as the degree of air superiority wherein the air force cannot effectively interfere with air assets?

Air supremacy refers to the condition in which one air force holds complete control over the airspace, so much so that the opposing air force is unable to conduct operations effectively. This level of dominance ensures that one's own air assets can operate without significant threat from enemy combatants. In this context, air supremacy allows for unrestricted use of airpower to support ground and naval forces, conduct reconnaissance, and engage in offensive operations with minimal risk of interference from the opponent.

The other terms, while related, do not capture the same level of control. Air superiority implies a lesser degree of dominance where the air force can effectively operate, but there may still be some capability from the opposing air force to interfere. Control of the air is a broader term that can encompass both air superiority and air supremacy, but it does not specifically indicate the total dominance of air supremacy. A favorable air situation denotes temporary advantages but lacks the definitive control that characterizes air supremacy.
