The Ragnar class was a class of three destroyers built for the Royal Swedish Navy before World War I. The class consisted of HSwMS Ragnar, HSwMS Sigurd, and HSwMS Vidar. The lead ship, Ragnar, was launched May 30, 1908. The design was based on the earlier destroyer Wale. The Ragnar class led a relatively quiet service life performing routine missions such as escorts and exercises between their commissioning before World War I and their decommissioning shortly after World War II.
