The Swedes were building three additional hemmemas at the shipyards within the fortress of Sveaborg when it was surrendered to the Russians in 1808, and all three were incorporated in the Russian Navy. Shortly afterward, the Russian Navy built its own 32-gun versions, with the final vessel launched as late as 1823. Two more were built in Sweden in 1809, "Birger Jarl" and "Erik Segersäll". "Birger Jarl" sank in an accident in 1813 and "Erik Segersäll" was planned for conversion as a paddlewheel steam battery for coastal defense, though the idea was eventually abandoned and the ship scrapped in 1826.
