The Project 775 Ropucha Large Landing Ship (Bol'shoy Desatnyy Korabl' BDK) is a beachable, general-purpose LST-type design with bow and stern ramps for unloading vehicles. A slightly smaller successor to the Alligator class, they were all built in Poland three distinct production runs. The last three units were an improved version with some variations in detail. Many have been retired, and remaining units may be in reserve, given the Russian Navy's decreased emphasis on amphibious operations.
Given the designation Large Landing Ship, the Ropucha class of tank landing ship was produced in Poland for the Soviet Navy. designed for roll-on, roll-off operations, the Ropucha design has both bow and stern doors, and the 630 square metres of vehicle deck stretches the length of the hull. The multi level supersturcture is designed to house two companies of naval infantry for extended periods. This, together with a 450 ton cargo capacity and the ability to carry 24 armoured vehicles, allowed the Soviet navy to employ the vessels on distant ocean operations. The collapse of the Soviet Union meant that capability was unlikely to be needed by Russia and the Ukraine, which inherited most of the ships of this class.
The class is not particularly well-characterized in the literature, and while all indicated names and numbers have been reported, the association of designations with the construction chronology is entirely conjectural, apart from the three Project 775M units. Although onl y 22 units have been identified through names or hull numbers, the production shipyard is quite specific that a total of 28 were produced.
