As of April 3062, the Aegis-class heavy cruiser Promise was a WarShip within the Clan Nova Cat touman and as such was serving the Second Star League as the SLS Promise within the Vision Naval Star. Also serving in the Vision Naval Star were two sister ships to the Promise, the SLS Blood Oath and the SLS Bond.
The Promise continued to serve in the Vision Naval Star at least until the beginning of the Jihad, but both sister vessels were reported to have been among the seven Nova Cat WarShips lost during a Trial of Possession conducted against Clan Ghost Bear for control of the Leviathan-class battleship CGB Rasalhague in May 3067. Following the loss of the Blood Oath and the Bond, the Vision Naval Star was joined by another Aegis-class sister vessel to the Promise, the SLS Path of Honor.
