The Gor class was a class of two Rendel (or "flat-iron") gunboats built for the Royal Norwegian Navy between 1884 and 1887. Small, nimble vessels, they were armed with a single large-caliber gun for offensive purposes and several small, quick-firing guns for self-defense. The main gun was large for such a small craft, roughly a quarter of the length of the whole vessel, and of the same caliber as heavy battleship guns of the same era. The Gor class was likely built in the belief that the ships would be able to inflict serious damage to an opposing battleship.
