An officer whose name is unknown functioned within the Imperial Navy throughout the time of the Imperial Era. Around 2 BBY, Darth Vader chose him to be a member of the team aboard the Empirical, a ship devoted to scientific studies. His assignment consisted of using the intercom to communicate the ship's state to the other members of the crew.
At an unspecified time, he joined the Galactic Empire's Navy. After becoming an officer, Vader chose him to work on the Empirical, his clandestine research ship.
While in the Dominus system, after Galen Marek, Vader's secret apprentice, was reconstructed on the vessel after a battle against Emperor Palpatine, Marek escaped, eliminating a large number of stormtroopers and fellow crew members. Because PROXY directed the ship to crash into the system's sun, the announcer was unable to get away because PROXY also released all of the escape pods. When the Empirical crashed into the star, the announcer died along with the rest of the crew.
