All the ships were constructed at the Wärtsilä Helsinki Shipyard, Finland, and had Pansio as their homeport.

During the late 1990s, the class was due to undergo a mid-life upgrade through 2006–2008 but this was rejected because of budget constraints.

The ships were decommissioned from Finnish service, and Helsinki and Turku were used for testing purposes before they were scrapped in 2011.

Two of the vessels were sold to the Croatian Navy for a price of €9 million (65 million kuna)[2] as a part of an off-set deal for the previous Croatian purchase of 126 Patria AMV vehicles.

They underwent a basic refit and repainting, and entered service in January 2009.
