The Tetan assault ships were described as being flying decks, and were used to transport soldiers and armored vehicles to planetary surfaces. This cargo was unleashed onto battlefields once the ship touched down. The distinctive silhuettes of these ships filling the skies became one of the most enduring symbols of the Great Sith War.
A fleet of these vessels were launched from the Tetan command station and were used by the Krath to subjugate the six worlds of the Empress Teta system including Empress Teta. Hundreds of ships clouded the skies above Koros Major cities and touched down on the outskirts, sending troops and tanks to conquer them.
