Project 20380 / Steregushchiy-class corvette

Also known as
  • Project 20380

  • Steregushchy-class corvette
  • Project 20380 corvette
  • Steregushchy class
  • Korvet-1

Project 20380, known to NATO as the Steregushchiy class, is a Russian Navy guided-missile corvette family designed by Almaz and built by Severnaya Verf and Amur Shipyard for coastal escort, anti-surface, anti-submarine, and amphibious-support missions. The baseline ships combine Uran anti-ship missiles, Redut or Kortik air defense depending on hull, Paket-NK torpedo launchers, and a Ka-27 helicopter facility in a reduced-radar-signature corvette that remained in active Russian service during the 2014 Russia-Ukraine War.

Combat Fit And Family Split

Project 20380 is most useful to read as a compact multimission corvette: the baseline hull carries a balanced anti-ship, air-defense, gun, anti-submarine, and helicopter package, while Project 20385 changes the strike-launcher architecture.

ElementProject 20380 fitReader-facing distinction
Anti-ship batteryTwo four-cell KT-184 launchers for 3K24 Uran / 3M24 missiles.Gives the baseline class a compact over-the-horizon surface-strike armament.
Air defenseRedut launchers on later ships; the lead ship is listed with a Kortik-M close-in module.Explains why images and references may show different point-defense arrangements across hulls.
ASW and torpedo defensePaket-NK launchers, sonar fit, grenade launchers, and a Ka-27 helicopter facility.Shows the class's escort role beyond missile-corvette surface attack.
Project 20385 branchLonger hull with UKSK vertical launchers and revised Redut arrangement.Separates the linked Gremyashchiy-class development from the baseline Steregushchiy branch.

Variants

Project 20380 designations separate the baseline Korvet-1 hulls from export and enlarged missile-corvette developments. Open sources vary on unrealized branches, so the rows below keep the distinctions to source-backed configuration differences.

Public sources describe it as Russia's post-Soviet ocean-going surface combatant class built around UKSK vertical launch cells for Kalibr, Oniks, and Tsirkon missiles, with later hulls receiving expanded launcher fits.

Russian service ships pair an eight-cell universal naval firing system for Kalibr or Oniks cruise missiles with a 76.2 mm gun and, on later units, Pantsir-M air defense; contracts and deliveries have involved Pella, Zelenodolsk, and Amur shipyards since the first hull was laid down in 2015.

Only Neustrashimy and Yaroslav Mudry were completed, but the class combines a 129.8 m hull, helicopter facilities, sonar-centered anti-submarine weapons, 3K95 Kinzhal naval surface-to-air missiles, Kortik close-in defenses, and Kh-35 Uran anti-ship missiles on the second ship. Neustrashimy is directly documented in the 2008 Gulf of Aden counter-piracy campaign.

Project 1155 ships combined bow and variable-depth sonar, two Ka-27 helicopters, SS-N-14/Rastrub missiles, torpedoes, RBU-6000 launchers, and gas-turbine propulsion; later Udaloy II and Marshal Shaposhnikov-style refits added heavier multi-role strike fits. Documented deployments tie Udaloy-class ships to Russia's Syria intervention and counter-piracy patrols off Somalia.
