The ''Rauma''-class missile boats ((フィンランド語:Rauma)-luokan ohjusvene) are a class of missile boat in use by the Finnish Navy. It is the predecessor of the ''Hamina''-class missile boats. The ships were constructed at the Hollming yards and Finnyards in Rauma, Finland. All the ships have their home port in Pansio. All four vessels underwent a 70 million EUR modernization program at the Western Shipyard in Teijo. The program includes the installation of a new version of the 9LV225 control and command system made by SAAB (the Mk.3 has been replaced by a Mk.4), the replacement of the Mistral SAM missiles with a MASS decoy system. The MASS system also replaces the Philax chaff and IR flares, the Thales Matilda radar warning system, and the 6 × 103 mm rails for rocket illuminants, that were previously fitted. The sonar and ASW systems are being completely renewed (the previous Simrad ST 240 has been replaced by a ST2400). The modernization programme began late in 2010 with all four vessels expected to be ready by autumn 2013. The first vesssel, ''Naantali'', was handed over to the Finnish Navy in May 2013. The modernization will allow the vessels to be operational into the 2020s.〔(The Finnish Defence Forces )〕 The vessel were previously armed with a sextuple Mistral SAM launcher, which could be replaced by a Sako twin-barrel 23 mm/87 anti-aircraft cannon (a modified version of the ZU-23-2). Additionally the vessel had a portable Mistral SAM launcher pad that could be mounted on the ship's deck, or on land, in order to protect the moored vessel. On 18 February 2015, the Finnish media reported that the ''Rauma'' class has been banned from use after fatigue damage was discovered in the vessels' hull.〔(Rauma-luokan ohjusveneet käyttökieltoon ).
