The Project 775, NATO reporting name Ropucha class (Polish for Toad), is a class of landing ship (large landing ship or Bol'shoy Desantnyy Korabl (BDK) in Soviet classification) built in Poland for the Soviet Navy. The ships were built in the Stocznia Polnocna shipyards in Gdansk, Poland. They were designed for beach landings, and can carry 450 tons of cargo. The ships have both bow and stern doors for loading and unloading vehicles, and the 630 square metres (6,800 sq ft) of vehicle deck stretch the length of the hull. Up to 25 armored personnel carriers can be embarked.
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. There are no facilities for helicopters.
In total, 28 ships of this type were commissioned from 1975 to 1991. The last three ships were of the improved variant Project 775M, also called Ropucha II. These have improved defensive armament and accommodation for a greater number of troops.
