The Battle Analysis Computer, or BAC, was an onboard starship computer system designed by General Jan Dodonna to provide starship captains and fleet commanders with tactical analyses, statistics and suggestions based on real-time feeds. If provided with accurate pre-battle inputs, such as estimated enemy strength and fleet logistics, the BAC could develop battle plans and predict outcomes. To enhance a commander's understanding of the multifaceted data output, the BAC could be connected to an astromech droid for a real-time holographic projection of the battle.
