The Ostracoda-class gunboat functioned as a naval craft employed by the Trade Federation for navigating swamps, rivers, and various other aquatic environments. Its design was derived from the AAT-1.
This gunboat was equipped with a rotating anti-aircraft laser turret, alongside dual laser cannons, and an energy bomb launcher. Its operational capability allowed it to traverse waterways in a manner analogous to the AAT's movement on terrestrial surfaces.
In the year 32 BBY, the Trade Federation utilized these vehicles during their invasion of Naboo. During the course of this invasion, the Naboo Royal Security Force engaged with these gunboats while endeavoring to assist the swamp-dwelling populace in resisting the invasion.
Subsequently, during the conflict, Lieutenant Gavyn Sykes of the NRSF successfully commandeered at least one gunboat amidst the turmoil. This captured vessel was then instrumental in the liberate of Federation enslavement camps, although its abandonment became necessary upon the operation's conclusion.
