Letun (Russian: Летун) was one of eight Orfey-classdestroyers built for the Russian Imperial Navy during World War I. Completed in 1916, she served with the Baltic Fleet during the war, but struck a naval mine in October that crippled her. The ship was under repair in Reval, Estonia, when the Soviets evacuated the city. Abandoned, Letun was broken up for scrap in 1927.
