The Steregushchiy class (Russian: Стерегущий, lit. 'Guarding'), Russian designation Project 20380, is a class of corvettes being built for the Russian Navy. Designed by the Almaz Central Marine Design Bureau, subsequent vessels were built to an improved design (Project 20381), incorporating the Zaslon-Redut SAM system. The ship full displacement and dimensions are large for a corvette, thus it is designated as a frigate by NATO. The Steregushchiy class has been further developed into the Gremyashchiy class (Project 20385) and Project 20386 subclasses. The export variant is known as Project 20382 Tigr.
