The Polnocny (or Polnochny)-class ships are amphibious warfare vessels. They were designed in Poland, in cooperation with the Soviet Navy and were built in Poland between 1967 and 2002. They now serve in several different navies, and some have been converted to civilian use. The name comes from the Stocznia Północna shipyard (Northern Shipyard) at Gdańsk, where they were built. 107 were built by 1986 (last 16 by Stocznia Marynarki Wojennej (Naval Shipyard) at Gdynia, Poland). In 2002, one ship of a modernised design NS-722 was built in Gdynia for Yemen.
The Polnocny class ships are classified as medium landing ships in the Russian Navy, and are loosely equivalent to Western tank landing ships. They are equipped with a bow ramp that allows beach landings. The Polnocny-C version can carry 8 armored personnel carriers, or 250 tons of stores. Unlike their Western counterparts, these ships can provide substantial fire support for landed troops with their embarked multiple rocket launchers. Other armament consists of anti-aircraft guns and short-range surface-to-air missiles.
