The Kaska was a Bajoran starship owned by Jekko Tybe. In 2328, he told Gwen Jones and Alynna Nechayev to take the Kaska and use it to escape from Bajor so they could tell the Federation what the Cardassians were doing there. As they were escaping the ship suffered a major systems failure and the Starfleet officers had to use environmental suits to survive. (TLE - Terok Nor novel: Day of the Vipers)
