The Deep Horizon Heavy Hauler is thickly armored against attack, with a sizeable hold and 10 turret mounts. Excellent for traders who expect to endure heavy fire, and rely on turrets for offense.
It's not fast and it's not the most manoeuvrable ship available. However, you can shoot the superlaser of the Death Star into this and Deep Horizon will survive. The hull on the ship is incredibly thick, so paired with laser turrets and/or missiles to eliminate enemy fighters (if the broadsides aren't your thing) the D Horizon is unstoppable.
