A High-angle gun was a relatively short, stubby artillery piece with a carriage specially designed to allow higher angles of fire in order to lob gunpowder-filled shells in high, arcing trajectories. The name is generally shortened to “angle-gun” by the gun crews themselves. (MTAT)

The angle-guns on the ICN Volcano weighed more than two times the new model Krakens, had a 10 inch bore, and fired 150 lb solid shot, or 100 lb shells. (HFAF)
