About Air Defender
Air Defender is a real-time strategy simulation in which you command a nation’s air defense network from a top-down view. You investigate radar contacts, identify airborne threats and decide whether to intercept them. You are not a pilot: you direct forces and manage the air defense assets available to the command center.
Command the defense
You oversee a radar network, interpret Identification Friend or Foe (IFF) data and issue orders to your forces. Analyze radar returns, monitor flight plans and assess electronic warfare (EW) intelligence to build a picture of the battlespace. You can scramble Quick Reaction Alert (QRA) fighters to investigate, shadow or engage contacts, while managing their fuel, weapons and mission objectives in real time.
Face the enemy
The opposing AI probes your defenses, launches coordinated attacks and adapts to your strategy. Your decisions determine whether hostile aircraft get through; a failure to stop them can lead to all-out war.
Game modes
You can play Endless mode or complete Training Missions. Endless challenges you to identify hostile contacts and prevent them from slipping through, while Training Missions help you prepare for combat.
