Description
The Pansio class consists of three mine warfare vessels built for the Finnish Navy at Olkiluoto between 1991 and 1992. Designated as mine ferries by the Finnish Navy, the vessels are designed for minelaying, transport, and the supply of naval forts.
The class underwent a mid-life upgrade from 2015 to 2017 to extend service into the 2030s. This modernization included the installation of new main and auxiliary engines and a high-pressure fire extinguishing system. During the upgrade, the previous twin-barreled guns were removed and replaced with a remote weapon station.
The class comprises the Pansio, Pyhäranta, and Porkkala. All three vessels remain in active service. Pansio is based at Pansio, while Pyhäranta and Porkkala operate from Upinniemi. In August 2022, the Pyhäranta ran aground in the Archipelago Sea near Turku, which resulted in a holed hull.
