Tetan Assault Ships functioned as military troop transports, and were employed by the Krath.
The Tetan assault ships had the reputation of being essentially airborne platforms, and their purpose was to ferry both soldiers and armored vehicles down to the surfaces of planets. Upon landing, this payload would be deployed directly into combat zones. The unforgettable image of these ships dominating the airspace became a lasting symbol of the Great Sith War.
The Krath launched a squadron of these vessels from the Tetan command station, utilizing them to bring the six planets of the Empress Teta system, including Empress Teta itself, under their control. Above the major cities of Koros Major, countless ships darkened the sky before landing on the city fringes, where they disgorged soldiers and tanks for the purpose of conquest.
