finland was forbidden to have torpedo boats after world war ii, but the nuoli class could quickly be converted into such, if need arose. in 1982 nuoli-6 was transferred and ferried to obbnäs torpedo test station to be used as test vessel for a new finnish-origin torpedo system, which failed. the trip to obbnäs was made in heavy weather - the waves were so hard that they damaged the wooden support structure of the bow. nuoli-6 was driven aground in obbnäs 1983 (summer/autumn) and was stricken.
