The Kor'Gar class attack ships numbered only a few dozen, and were the prime vessel of House Kor'Gar. The ships were used to patrol the House's territories in the Klingon Empire and to monitor the 3 alien colonies they had subjugated. (The Vreese, The Selleresh and the Vumlax) as well as maintain their shipping routes. These ships were over armed and under defended, primarily in their aft shields.
