The Katanpää class consists of three vessels:  MHC Katanpää (40), MHC Purunpää (41,) and MHC Vahterpää (42). 

These Katanpää-class vessels are modern mine sweepers constructed at the Italian Intermarine shipyard, fitted with versatile systems and equipment. The Katanpää-class vessels belong to the Coastal Fleet’s 4th Mine Countermeasures Squadron. Their home base is Pansio, Turku. 

The task of these mine sweepers is to clear mines and protect maritime connections important to Finland from mines.  These vessels can also be used for mapping the seafloor, defuzing underwater explosives, underwater search and identification tasks, and various types of executive assistance tasks.
