Opytny (Russian: Опытный, lit. 'Experienced') was the only member of her class of destroyers built for the Soviet Navy during the 1930s. The Soviet designation for her class was Project 45. She was completed in 1941 and fought in World War II as part of the Baltic Fleet. She was indigenously designed in contrast to the Type 7 which was built with Italian assistance and intended as a prototype for future Soviet destroyers. She was not a successful ship, with severe problems with her machinery and stability. Her intended armament of twin-gun turrets were transferred to the destroyer leader Tashkent and replaced by single gun mounts.
