Emperor's fleet
The Emperor's fleet, observed in 2 BBY, represented a collection of warships that formed a component of the Imperial Navy, specifically a fleet. As its designation suggests, this fleet operated under the direct authority of the Galactic Emperor, the leader of the Galactic Empire, and was deployed in situations deemed significant enough to warrant the Emperor's personal presence.
History
This particular naval formation was put together to escort Emperor Palpatine during his inspection of the Star Dreadnought Executor, which was still under construction. The fleet comprised a minimum of eight ships, featuring multiple Imperial-class Star Destroyers alongside several vessels exhibiting design characteristics akin to the Executor-class, notably a comparable hull structure.
