Project 20386 is Russia's newest class of corvettes being constructed by Severnaya Verf for the Russian Navy. Based on the Steregushchiy and Gremyashchiy classes, the new class was to have been larger, incorporating a more stealthy design. As originally conceived, there were plans to build a series of at least ten such corvettes.

The Steregushchiy class, 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, 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 and Project 20386 subclasses. The export variant is known as Project 20382 Tigr.
