Ondatra-class

Project 1176 Akula, designated by NATO as the Ondatra class, is a series of landing craft built for the Soviet and Russian navies. Production occurred between 1971 and 2009 at the Azovskiy, Rybinsk, Vladivostok, Vympel, and Sokolskaya shipyards. The vessels are categorized as Desantanyy Kater (DKA).

The design is similar in function to the United States Navy Landing Craft Mechanized (LCM). It features a shallow draught intended for amphibious operations and littoral combat. The craft is equipped with the Mius navigation radar. Primary capabilities include the transport of a main battle tank, infantry units, or cargo. In support of larger naval operations, Ivan Rogov-class landing ships utilized the Ondatra as a tug for Lebed-class air-cushioned landing craft. The Project 1176 is being replaced in service by the Project 21820 Dyugon-class.

The class entered service in 1971. In addition to the Soviet and Russian fleets, the vessels have been operated by the Ukrainian Navy and the Border Police of Georgia. Georgian service began in 1992 with the acquisition of two units, MDK-01 and MDK-02. The Ukrainian vessel Svatovo entered service in 1998 and was reportedly captured by Russian forces in March 2022. Operational losses include D-106, which was destroyed by a mine near Mariupol in 2022, and an unidentified unit reported destroyed by a Ukrainian sea drone near Chornomors'ke in November 2023. While many vessels were decommissioned after 1990, active units remain assigned to the Northern, Pacific, Baltic, and Caspian fleets.
