What does Defensive Counter Air (DCA) aim to accomplish?

Defensive Counter Air (DCA) focuses on the protection of friendly airspace from enemy aircraft and other aerial threats. By prioritizing the neutralization of enemy forces that might invade or threaten this airspace, DCA seeks to ensure the safety and effectiveness of friendly forces and operations. The main objective is to maintain air superiority and secure the operational environment for ground and aerial units, thus allowing for the freedom to conduct missions without the risk of enemy air attacks. This alignment with the goal of neutralizing threats in friendly airspace makes this answer the most accurate in the context of DCA operations.
