The most infamous of the class, the Saint Joan was escorting convoys carrying personnel and supplies to SLDF units in the Rim Worlds Republic when it encountered six privateer vessels in November 2674. After it lost main power while attempting to defend its charges, the Captain discovered that the ship's auxiliary power could not provide life support and fire the weapons at the same time, the now helpless ship destroyed within minutes.
