What is the objective of Passive Air Defense?

The objective of Passive Air Defense focuses on minimizing vulnerability to air attacks through various non-direct engagement methods. This includes the use of deception and camouflage, which play significant roles in obscuring the locations and movements of military assets from enemy reconnaissance and targeting efforts. By employing techniques such as concealment, physical barriers, and misdirection, forces can remain undetected, reducing the likelihood of being targeted by enemy aircraft.

In contrast, the other options revolve around offensive or active measures. Offensive strikes aim to engage and destroy enemy forces preemptively, while active measures involve immediate responses to threats using direct action. Designing advanced weapon systems is aligned with offensive capabilities aimed at countering threats, rather than employing strategies to enhance survivability without direct confrontation. Therefore, option C stands out as the primary means of achieving the objectives of Passive Air Defense.
