The Kathol Republic Navy was the space defense force for the Kathol Republic. The Navy patrolled the Republic's territory and defended it against outside aggressors. The backbone of the navy was made up of at least eight Marauder-class corvettes, and the fleet was considered obsolete by the Galactic Empire, and of little threat. The fleet was commanded by Hendric Faile.

Two corvettes, including the Bravado III, engaged forces allied to Moff Kentor Sarne posing as a New Republic vessel in 8 ABY.
