The Ivan Gren-class landing ship (Project 11711) is a Russian large landing ship / landing ship tank designed by Nevskoe Design Bureau and built by Yantar Shipyard. The class carries troops, armored vehicles, cargo, helicopters, and obstacle-laying payloads for amphibious and naval transport missions; Pyotr Morgunov was part of Russia's Black Sea amphibious force during the full-scale invasion of Ukraine.
Russia deployed the Ivan Gren-class landing ship Pyotr Morgunov into the Black Sea with the pre-invasion amphibious buildup, kept it in the theater during the full-scale war, and used landing ships for transport and supply runs after the Kerch Bridge attack. Sources document presence and logistics use, not a confirmed opposed landing by this class.
Role detailsProject 11711 is more than a beaching transport. Nevskoe describes the design as a ship for taking aboard, carrying by sea, and landing troops and equipment with other fleet assets, while also supporting naval transport and selected obstacle or sensor-laying tasks.
| Role | How it appears in sources | Reader note |
|---|---|---|
| Amphibious lift | First-series ships are described with capacity for tanks, armored vehicles, troops, and two helicopters. | The class adds modern Russian landing capacity but no source here confirms a contested landing by this class in Ukraine. |
| Theater transport | Naval News reported Pyotr Morgunov carrying supplies between Russia and Sevastopol after the Kerch Bridge attack. | In wartime Black Sea use, logistics movement is the best directly documented role. |
| Second-series aviation and boat support | EDR describes the 2024 second-series model with helicopter, UAV, and landing-craft accommodation. | The enlarged Project 11711M/Cayman design points toward a broader assault-support layout. |
The catalog entry covers the Project 11711 family rather than a single hull. The main split is between the first two ships and the enlarged second-series design represented by Vladimir Andreev and Vasily Trushin.
| Configuration | Documented features | Source-supported status |
|---|---|---|
| First series | About 6,000 t displacement, about 120 m length, about 18 kt speed, and a mission set centered on landing troops and vehicles on an unimproved coast. | Ivan Gren entered service in 2018; Pyotr Morgunov entered service in 2020. |
| Second series / Project 11711M | EDR reports about 8,000 t displacement, about 150 m length, a changed superstructure, unchanged gun armament pattern, and room for helicopters, UAVs, and landing craft. | Vladimir Andreev and Vasily Trushin were laid down at Yantar in April 2019. |
| Project 11711E / Cayman | Nevskoe identifies an export appearance and promotional package based on Project 11711; EDR uses Cayman for the second-series Project 11711 model shown in 2024. | Listed as design and export context, not as a separate documented combat-use entry. |
Project 11711 covers the first two Ivan Gren-class ships and later enlarged second-series/export configurations that keep the amphibious-transport mission but change the superstructure, displacement, aviation facilities, and small-craft provisions.
| Variant | Configuration | Designation notes |
|---|---|---|
| Project 11711 first series | Baseline Ivan Gren and Pyotr Morgunov configuration | Nevskoe's first-series pages describe a roughly 6,000-ton large landing ship intended to carry and land troops and equipment on an unimproved shore, with Ivan Gren accepted in 2018 and Pyotr Morgunov accepted in 2020.

| Project 11711M / second series | Enlarged Vladimir Andreev and Vasily Trushin configuration | Naval News and EDR describe the second series as an enlarged Project 11711 design with greater displacement, a revised superstructure, expanded aviation or deck arrangements, and continued construction at Yantar.
