The Dauntless-class heavy cruiser was the second largest cruiser that saw service with the Rebel Alliance fleet during the course of the Galactic Civil War.
The cruiser was originally built as a luxury vessel but was converted into a combat ship during the Galactic Civil War. The Dauntless-class served on the front line of many space battles during the course of the Galactic Civil War and even into the Yuuzhan Vong War.
The Endor was a Dauntless-class cruiser that served with the New Republic, and was destroyed in 13 ABY.
