During the Battle of Jakku, after former Grand Admiral Rae Sloane defeated her former ally, Counselor to the Empire Gallius Rax, she was instructed by Rax before he died to take a replica of the Imperialis, find the Eclipse and reform the Empire. It was believed to have been destroyed by a fleet of New Republic vessels with Ackbar's flagship, Home One, firing the ship-killing shot by the year 5 ABY. At one point during its service, the Eclipse bombarded a celestial body along with three Imperial-class Star Destroyers.

In the report, Ackbar mentioned the Eclipse, noting that it was rumored to be the flagship of Emperor Palpatine, which turned out to be accurate. Sometime after the Arrth-Eno Mission undertaken by the Rebel Alliance during the Galactic Civil War, Rebel Alliance Admiral Gial Ackbar wrote a report to Commander-in-Chief Mon Mothma regarding the Executor-class Star Dreadnought. It's time to rejoin with those who came before.' ―Brendol Hux, and Rae Sloane upon seeing the Eclipse
