The Galleon served as the earlier, non-combat version that came before the Star Galleon-class frigate.
The Galactic Republic era saw the initial deployment of this class of ship. Its service persisted within the Imperial Navy even after the Clone Wars had concluded.
Within Star Wars: Rebellion, the Galleon is portrayed through its in-game statistics as a transport with limited speed and durability, possessing subpar shields and a class 2 hyperdrive. It could carry approximately two regiments from the Imperial Army, though direct comparisons are challenging.
