The 1907 parliament voted a second submarine and to get new ideas from a European builder, the contract was given to the Italian yard. The boat corresponded to the Italian Foca. Hvalen received naval publicity all over the world as the crew made the voyage to Sweden without any assistance or accompanying vessel. The submarine was taken over on 9 July 1909 and on the 30th she began the 4000nm voyage to Stockholm, where further tests were made. These ended on 18 December and the submarine was accepted that day.
Her wreck was sold and BU after being sunk as a target in 1924.
