Russian destroyer Sibirsky Strelok

Sibirsky Strelok (Russian: Сибирский стрелок) was a Okhotnik-class destroyer built for the Imperial Russian Navy during the first decade of the 20th century. Completed in 1907, she served in the Baltic Fleet and participated in the First World War. The ship was seized by the Bolsheviks in 1917 during the October Revolution and was placed in reserve in early 1918. Sibirsky Strelok was transferred to the Special Technical Bureau (Ostekhbiuro) in 1925 as an experimental ship and was renamed Konstruktor (Russian: Конструктор) the following year. The Soviet Navy reassumed control of the ship in 1939, although her role remained the same.

Shortly after the Axis invasion of the Soviet Union in mid-1941, Konstruktor was converted into an escort ship and transferred to Lake Ladoga. She was sunk by Finnish aircraft later that year, but was salvaged and converted into a gunboat by 1943. The ship reverted to her experimental role in 1945. Konstructor was struck in 1957.
