Meridian trench

"You are required to maneuver straight down this trench and skim the surface to this point. The target area is only two meters wide. It's a small thermal exhaust port, right below the main port."

- Alliance general Jan Dodonna

The meridian trench of the Galactic Empire's Death Star, situated near the north pole of the battle station, hosted its only weakness, the thermal exhaust port. After the Alliance to Restore the Republic managed to steal the plans to the Death Star, they discovered that fatal flaw. Consequently, the Alliance decided to utilize the meridian trench to fire into the unprotected exhaust port, triggering a chain reaction that would cause the Death Star's main reactor to explode. After navigating his T-65B X-wing starfighter through the meridian trench, Luke Skywalker managed to destroy the battle station as planned.
