The Grysk armada represented the naval forces, or navy, of the Grysk Hegemony's military. In "Jixtus," it is stated that its size was so immense that, were it deployed above Csilla, it would completely obscure the sky. This fleet included a variety of warship types, notably the massive Shatter-class WarMasters, the somewhat smaller StoneCrusher-class WarMasters, and the Prism-class BattleChiefs.
The 2018 novel Thrawn: Alliances, penned by Timothy Zahn, marked the initial appearance of the Grysk armada. The name "Grysk armada" was first used to identify it in Zahn's 2021 novel, Thrawn Ascendancy: Lesser Evil.
