PLA Military Doctrine And Defense Strategies Practice Test

Deterrence-through-density centers on creating a dense, layered air-defense network that makes entering the airspace costly and risky for the attacker. The core idea is to deny air power by saturating the environment with sensors, surface-to-air missiles, and integrated command-and-control, so the adversary is deterred from acting. For air operations, this means the defender should avoid exposing its own air assets in the contested space and instead rely on the defensive network to deter and interdict, using early warning and missiles rather than large-scale offensive sorties. The emphasis is on protecting airspace and signaling deterrence, not on deploying a high volume of own aircraft into the area. The other options don’t fit: pushing more US air activity would undermine the deterrent effect; dismantling air defenses would remove the mechanism that deters entry; relying only on diplomacy ignores the military capability needed to deter air power in the first place.
