History.
From 1993-1999 a total of 12 ships were constructed and entered service with the Swedish navy and amphibious corps.
The class was about to retire in 2014 but after the Russian intervention in Ukraine and Russian military build-up in the Baltic sea it was decided that the boats will remain in service and be modified as well.
In 2020 the first six boats of the class had a comprehensive overhaul and upgrade program in which they were equipped - among other things - with the Kongsberg Maritime sonar for Anti-submarine warfare.
