Akula was the first submarine fully developed and built by Tsarist Russia for long patrol missions. It was built at the Baltic Shipyard, St Petersburg and launched in 1909. During its lifetime it was used for 19 patrols in the Baltic Sea during World War I. In 1915 it was sent on a mission to lay four mines on a fairway between Klaipeda and Liepaja. Instead, on November 15th, it itself hit a mine and sank en route to the mission location. All 35 crewmembers perished.
