HSwMS Artemis is a signals intelligence gathering vessel currently under construction for the Swedish Navy.
The ship is to replace Sweden's only signals intelligence vessel, HSwMS Orion, which was launched in 1984. Artemis was ordered on 10 April 2017 and was laid down on 19 June 2018 at the Polish shipyard Nauta and the ship was launched on 17 April 2019. The ship will be 74 metres (242 ft 9 in) long and it will have a displacement of 2,200 tons.
The project was delayed in March 2021 because the Polish shipyard had economic difficulties and was unable to finish the ship. As a result it was towed to Saab Kockums shipyard in Karlskrona, Sweden in February 2022 where construction of the ship was finished with the help of staff from Poland. Artemis was handed over by Saab Kockums to the Swedish defence material administration on 28 April 2023. The outfitting of the ship is being performed by the National Defence Radio Establishment. Artemis is planned to be commissioned by 2024 at the latest.
