Heavy gun

The Heavy gun was a type of artillery used on wartime Lucrehulk-class battleships.

Characteristics
The gun was shaped with a short, thick barrel and was the heaviest gun model fitted to the ships. Because of its power, it was the least numerous of the three main gun types on the Lucrehulk-class, flanked by both quad turbolaser cannons and long guns.
