The Sentri class medium fighter is the fictional fighter craft of the Centauri Republic in the fictional universe of Babylon 5.
A highly advanced design, the Sentri is extremely fast and maneuverable, and can outfly even the best EarthForce and Narn fighters. Only the Minbari Nial-Class fighter is faster and more maneuverable. However, the Sentri's speed comes at a price: the fighter has thin armor plating. The Sentri is thus highly vulnerable to direct hits from enemy ships and even a single shot from an enemy fighter can destroy it. The Sentri is capable of flying both in space and in a planetary atmosphere. It is also equipped with a sophisticated autopilot system which can fly the fighter even when the pilot has blacked out in an extreme maneuver during battle.
