The Unerring, a starship, was a part of the New Republic Defense Fleet. It fought against the Galactic Empire during the Galactic Civil War. Around 5 ABY, this ship, along with its accompanying vessels, aimed to put an end to a plot orchestrated by a vizier of the deceased Emperor Palpatine. During a year's conference with the New Republic High Command, Admiral Ho'ror'te used a hologram to inform those present about the Unerring and the sacrifices made by it and its escort ships.
Alexander Freed mentioned the Unerring in his 2021 novel, Victory's Price. This book served as the concluding chapter in his Star Wars: Alphabet Squadron trilogy.
