A turbolaser was a powerful laser cannon turret stationed aboard capital ships, such as the Imperial I-class Star Destroyer and the MC80 Liberty Type Heavy Star Cruisers, as well as space stations, such as the DS-1 Orbital Battle Station and the Golan I Space Defense Platform. Other notable Spacecraft that were equipped with turbolasers included the Corvette Tantive IV and the Dreadnought Malevolence.
A turbolaser's effectiveness was weakened drastically as the bolt moved through layers of a planet's atmosphere, making them largely ineffective even against unshielded targets. However, this could be ameliorated by moving the ship deeper into the planet's stratosphere.
Some turbolasers had a limited range of effectiveness, even in the vacuum of space; the turbolaser armaments of the Imperial I-class Star Destroyer Chimaera had a combat range of less than 1,200 kilometers. After said distance, they would be unable to penetrate any type of sufficient armoring. Likewise, the Supremacy's heavy turbolasers were unable to cause notable damage to the shields of the Star Cruiser Raddus from a long distance.
