Katanpää-class mine countermeasure vessel

Katanpää-class mine countermeasure vessels are a class of three multipurpose mine countermeasure vessels (MCMV) ordered by the Finnish Navy. The nearly 250 million euro contract was awarded to the Italian shipyard Intermarine S.p.A. in 2006. Initially, all three vessels were scheduled to be delivered by 2014 and the class was expected to achieve operational readiness by 2015, but there have been various delays and the last vessel was handed over to the Finnish Navy in November 2016.
