Emperor's personal shuttle
The personal shuttle of the Emperor, alternatively referred to as Palpatine's personal shuttle, was a Lambda-class shuttle utilized by the Galactic Emperor Palpatine.
Attributes

This shuttle possessed a cloaking device and was identifiable by a grey band across its front. It is believed that only a small contingent of the Emperor's Royal Guardsmen comprised its crew.
Historical Information
Emperor Palpatine frequently employed it for journeys across the galaxy.
On one occasion, Palpatine's shuttle sustained damage while the Emperor was aboard, resulting from a premature (and unintentional) shot fired by the would-be assassin Raygar. Raygar had been attempting to target the pod containing a pair of Ewoks, Latara and Teebo. Following the incident, the Emperor personally punished Raygar for "high treason".
During the Battle of Korriban, Renegade Squadron is assigned the mission to extract a data pack from Palpatine's shuttle during his visit to Korriban. This operation formed part of the broader ambush strategy being developed in anticipation of the Battle of Endor.

The Emperor utilized the shuttle to travel to the second Death Star orbiting Endor. Upon its arrival, it landed at Hangar 272. To honor his arrival, the Imperials organized aerial parades outside the station and had all personnel, including numerous technicians, droids, and military personnel, standing at attention to acknowledge their leader's arrival. The destruction of the battle station during the Battle of Endor resulted in the shuttle's destruction.
Behind the Curtains
The Return of the Jedi radio dramatization suggests that Luke Skywalker made his escape from the second Death Star using Palpatine's shuttle. However, the novel The Rise and Fall of Darth Vader contradicts this, asserting that the escape occurred in Darth Vader's shuttle. Starships of the Galaxy confirms that Palpatine's shuttle was destroyed along with the second Death Star, thereby negating the possibility of Luke's use of the ship. Furthermore, the film itself depicts a shuttle lacking the characteristic gray stripe on its front, and the ship is observed departing from a smaller docking bay instead of the larger one, providing further confirmation that it was not Palpatine's personal transport.
