Trenchenovu, located in both the Outer Rim Territories and the Western Reaches along the Corellian Trade Spine, was a celestial body. At this location, the Galactic Empire maintained the Trenchenovu shipyards. Nath Tensent, along with his Rebel Alliance squadron, launched an attack on these shipyards; however, the mission failed, leaving Tensent as the sole survivor.
The "Trenchenovu shipyards" were initially referenced in Alexander Freed's Star Wars: Alphabet Squadron trilogy, specifically in the first book, the 2019 novel Alphabet Squadron.
