The Russian Navy does not use the name frigate. Most ships are typed by their function and mission. MPK stands for Malyy Protivolodochnyy Korabl, literally small anti-submarine ship. Most of these are designed for and employed in anti-submarine warfare. However, others are designed for coastal defense and patrol work. They are designed to patrol or guard sea areas.
Throughout the 1960s and 1970s the Soviet Fleet strongly emphasized its ASW capabilities. Project 1124 Albatros fit in with this strong emphasis on anti-submarine capability. They were designed to guard the sea frontiers of the Soviet Union. They have been built in five series. NATO assigned a code name for these small vessels based on Russian nicknames. Project 1124 vessels were named Grisha, which can be translated to Greg.
MPK "Alexandrovetc" was built by Zelenodol'sk Zavod, Kazan. Laid down 23 Mar 1980, completed 31 Nov 1982. Laid up 24 Nov 1982.
From 23 Mar 1980 this warship has name "MPK-49", from July 2004 to present moment - "Alexandrovetc".
