The Ropucha class, Soviet designation Project 775, is a class of landing ships (large landing ship in Soviet classification) built in Poland for the Soviet Navy. The ships were built in Poland in the Stocznia Polnocna shipyards in Gdansk. Designed for beach landings, they can carry a 500 tonn cargo. The ships have both bow- and stern-doors for loading and unloading vehicles, and the 630 square metres of vehicle deck stretches the length of the hull. In total, 28 ships of this type were commissioned from 1975 to 1991. The last three ships were of the improved variant Project 775/III, also called Ropucha II.

While designed for roll-on/roll-off operations, they can also be loaded using dockside cranes. For this purpose there is a long sliding hatch-cover above the bow section for access to the vehicle deck. The vessels can reach speeds of 18 knots and range out to 4000 nautical miles - making them somewhat independent "Blue Water" vessels.

The Ropucha-class ships have self-defense-minded weaponry installed, particularly to support shoreline actions and defend against low-flying threats. 2 twin-barreled 57mm AK-257 autocannons are carried (Ropucha I ships only) as is a single 76mm turreted gun fit (Ropucha II). To this is added 2 x 30 122mm MS-73 Grad-M rockets for area suppression. Strela-2 or Igla short-range surface-to-air missile launchers also aid in airspace deterrence. Close-in support is through 2 30mm AK-630 digital combat units sporting Gatling-style guns (Ropucha II).

Large Landing Ship BDK-54 laid down on 22 November 1988 at the Stocznia Polnocna Shipyard, Gdansk, Poland (yard No.775/26), launched on 19 May 1989, commissioned on 12 October 1990 and switched on in structure of the Black Sea fleet.

23 November 1998 was renamed to Azov.

Now in service.
