The K.u.K. Kriegsmarine was the naval force of the Austro-Hungarian Empire, active from 1867 until the end of World War I in 1918. It played a crucial role in protecting the empire's maritime interests in the Adriatic Sea and beyond. The fleet included battleships, cruisers, and submarines, reflecting the technological advancements of the time. The K.u.K. Kriegsmarine was involved in various naval operations during the war, facing challenges from the Allied Powers. Despite its efforts, the fleet struggled with limited resources and strategic disadvantages. After the empire's dissolution, the navy was disbanded, and its ships were either scrapped or transferred to successor states.
