Leningrad-class destroyer
The six Leningrad-class destroyer leaders were built for the Soviet Navy in the late 1930s. They were inspired by the contre-torpilleurs built for the French Navy. They were ordered in two batches of three ships each; the first group was designated Project 1 and the second Project 38. These ships were the first large vessels designed and built by the Soviets after the October Revolution of 1917.

A flotilla leader was a warship of late 19th century and early 20th century navies suitable for commanding a flotilla of destroyers or other small warships, typically a small cruiser or a large destroyer. The flotilla leader provided space, equipment and staff for the flotilla commodore, including a wireless room, senior engineering and gunnery officers, and administrative staff to support the officers. Originally, older light or scout cruisers were often used, but in the early 1900s, the rapidly increasing speed of new destroyer designs meant that such vessels could no longer keep pace with their charges. Accordingly, large destroyer designs were produced for use as leaders.
