Bogey One, a designation used by the Springhawk crew, referred to a Grysk Warship. This warship, known as Bogey One, engaged in a battle with both the Springhawk and the Aelos. In terms of appearance, Bogey One resembled a scaled-down version of a Shatter-class WarMaster. To safeguard its missiles, Bogey One utilized dibbers as a defensive measure. Following the destruction of the Kilji picket cruiser named Hammer, it successfully fled the conflict.
Bogey One made its debut in Thrawn Ascendancy: Lesser Evil, the 2021 novel that concludes the Star Wars: The Ascendancy Trilogy penned by Timothy Zahn.
