The Project 1124 Albatros, known to NATO as the Grisha class, is a Soviet anti-submarine corvette family built for coastal ASW patrols, base protection, and convoy escort. The compact ships combined sonar, Osa-M point-defense missiles, torpedo tubes, and RBU-6000 launchers; Ukrainian Grisha-family hulls later became part of the 2014 Russia-Ukraine War record through the Crimea naval seizures and the destruction of ex-Ukrainian Ternopil as a Russian Black Sea Fleet target ship in 2023.

Role in Conflicts

Ukrainian Hulls In Crimea

The Russia-Ukraine War evidence for this class is strongest around Ukrainian Grisha-family ships seized during the Crimea operation, not around confirmed gun or ASW combat employment by the class.

Class Variants

The Project 1124 family is easiest to read as a sequence of mission-fit changes rather than a single weapons loadout. The Soviet designation remained centered on small anti-submarine ships, while NATO reporting names split the visible branches into Grisha I through V.

VariantNATO nameDistinguishing fit
Project 1124Grisha IBaseline coastal ASW ship with Osa-M point defense, torpedo tubes, and RBU-6000 ASW launchers.
Project 1124PGrisha IIBorder-guard branch with a second 57 mm gun mount replacing the forward missile system.

Variant grouping is synthesized from GlobalSecurity, Naval Encyclopedia, and RussianShips.info class references.

Variants

Project 1124 records combine Soviet project numbers with NATO Grisha reporting names; the family split mainly reflects navy, border-guard, test, and modernized ASW branches.

Carried Naval Weapons

Project 1124 ships were small hulls with a dense ASW and point-defense fit. Exact weapons varied by branch, but open references consistently identify RBU-6000 ASW launchers and Osa-family shipboard point-defense missiles as core elements of the class.

Carried itemItem typeCarriage evidence
RBU-6000 Smerch-2 anti-submarine rocket launcher, Shipboard anti-submarine rocket launcher, Naval SystemsRBU-6000 Smerch-2 anti-submarine rocket launcherShipboard ASW rocket launcher

GlobalSecurity identifies RBU-6000 launchers among the Project 1124 armament, and the existing RBU-6000 entry documents the launcher as a Soviet shipboard ASW rocket-depth-charge system.

The seven-ship series paired Metel stand-off ASW missiles, Shtorm and Osa naval surface-to-air systems, rocket depth-charge launchers, torpedoes, sonar, and a Ka-25 helicopter facility; its last conflict-linked appearance was the decommissioned Ochakov being scuttled by Russian forces as a blockship in Donuzlav during the 2014 Russia-Ukraine War.

The family combined gas-turbine propulsion, URK-5/Rastrub anti-submarine missiles, Osa-M/Osa-MA point defense, guns, torpedoes, and RBU launchers, then branched into border-guard, Indian export, and Russian guided-missile derivatives. Its 2014 Russia-Ukraine War record centers on Ukraine's Krivak III-derived Hetman Sahaidachny, which was scuttled at Mykolaiv in 2022 to avoid capture.
