## Who Is IRRA? IRRA — the Integrated Responsive Resource Algorithm — is the AI command system embedded in the Aegis Carrier Fleet. She's not just a tactical HUD or an auto-pilot. She's a full battlefield coordinator that monitors every squadron, every threat vector, and every supply line simultaneously. From the player's perspective, IRRA is your co-pilot and the voice of the fleet. You make the big calls. She handles the execution with machine precision. ## The Technical Challenge Building IRRA meant solving a real problem: how do you give players the feeling of commanding a carrier group without overwhelming them with micromanagement? The answer was layered autonomy. IRRA handles formation-level decisions — spacing, threat response, fuel routing — while the player focuses on mission-level decisions: which zone to prioritize, when to commit the reserve squadron, when to break off an engagement. ## Behavior Trees, Not Scripts Rather than scripting specific responses to specific scenarios, IRRA runs on a behavior tree architecture. Each squadron has its own sub-tree that evaluates threat proximity, fuel state, and player-issued objectives every tick. This means IRRA's behavior emerges from the situation rather than following a script. Players who've tested the alpha have commented that the fleet feels *alive* in a way scripted AI rarely does. We'll share more about the fleet management interface in the next update.
