The Pansio-class minelayers^[1] are a three-strong class of mine warfare vessels used by the Finnish Navy, built between 1991 and 1992.^[2] The vessels can also be used for transport or to supply the naval forts. The vessels can carry a 100-ton load.

The ships are referred to as "mine ferries" in the Finnish Navy.

Mid-life upgrade

The three vessels went through a mid-life upgrade between 2015 and 2017 and are now expected to serve until the 2030s. The upgrades included new main and auxiliary engines, as well as a new high-pressure fire extinguishing system.^[3] The vessels were also equipped with a Saab Trackfire remote weapon station with a 7.62 mm PKM machine gun and a 40 mm Heckler & Koch GMG. The two Sako twin-barreled 23 mm/87 (modified ZU-23-2) were removed.

Service

On 24 August 2022 Pyhäranta ran aground in the Archipelago Sea, off Turku, Finland. Her hull was holed.^[4]
