Opytny (Russian: Опытный, lit. 'Experimental') 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 originally named Sergo Ordzhonikidze and was the first Soviet destroyer to be indigenously designed. Renamed Opytny in 1940, the ship was intended as a prototype for future Soviet destroyers.
