Rauma-class

The Rauma class is a series of four missile boats operated by the Finnish Navy. Built at the Rauma shipyard by Hollming and Finnyards, the class succeeded the Helsinki class and preceded the Hamina class. The Finnish Navy ordered the lead vessel in 1987, and the full class entered commission between 1990 and 1992.

The vessels utilize waterjet propulsion and are equipped with the Saab 9LV225 Combat Management System. Sensor systems include surface search radar, navigation radar, and towed array sonar. The armament suite consists of anti-ship missiles, a Bofors main gun, and machine guns. For anti-submarine operations, the ships carry ASW mortars and towed sonar. The design allows for the installation of mine rails for tactical mining in place of missiles.

Between 2010 and 2013, all four vessels underwent a modernization program at the Western Shipyard in Teijo. This update included the installation of a new version of the Saab command and control system, the replacement of previous air defense missiles and flare systems with a Multi Ammunition Softkill System (MASS), and a renewal of the sonar and ASW equipment. These upgrades were intended to extend the operational life of the vessels into the 2020s.

The class consists of the Rauma, Raahe, Porvoo, and Naantali, all of which are based at Pansio. In February 2015, the Finnish Navy suspended operations of the class following the discovery of hull fatigue damage. After completing repairs, the vessels returned to active service in 2016. The Finnish Navy plans to retire the class upon the commissioning of the Pohjanmaa-class corvettes in the late 2020s.
