The Yinchorri's main capital ships used for military purposes were Yinchorri attack ships. These vessels, employed by the Yinchorri, possessed a size comparable to that of gunships or corvettes. It's important to note that the Yinchorri didn't originally construct these ships; instead, they acquired them through theft from the Golden Nyss Shipyards. The stolen vessels played a role in the defense of the Yinchorri system and were also utilized in an attack on Mayvitch 7.
