The Carola class was a group of six steam corvettes built by the German Kaiserliche Marine in the late 1870s and 1880s. The class comprised Carola, the lead ship, Olga, Marie, Sophie, Alexandrine, and Arcona. They were ordered to replace older sailing vessels that were no longer sufficient to protect German interests around the world. Intended for service in the German colonial empire, the ships were designed with a combination of steam and sail power for extended cruising range, and they were equipped with a battery of ten 15-centimeter (5.9 in) guns. Relying primarily on sail power for their long-range deployments, the ships were obsolescent before construction began.
