Project 20385 (Gremyashchiy)

The Project 20385 Gremyashchiy-class is a series of advanced multi-purpose corvettes developed for the Russian Navy. These stealth-capable vessels are designed for anti-submarine warfare, anti-surface warfare, and air defense missions in littoral zones.

Designed by the Almaz Central Marine Design Bureau as an evolutionary upgrade to the Project 20380 class, Project 20385 was developed to integrate the UKSK vertical launching system for Kalibr cruise missiles. The program faced significant delays when 2014 international sanctions forced a redesign to replace German-supplied MTU diesel engines with domestic Russian alternatives. The lead vessel, Gremyashchiy, was officially commissioned into the Russian Navy's Pacific Fleet in December 2020. Since completing its transit to the Far East in 2021, the ship has participated in routine patrols in the Sea of Okhotsk, while additional sister ships remain under construction to reinforce Russia's regional naval capabilities.
