}} | 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 {{HSwMS|Wale||2}}. 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.
