Project 23550 patrol icebreaker

Also known as
  • Project 23550
  • Project 23550 icebreaking patrol ship
  • Ivan Papanin
  • Purga

Project 23550 is a Russian multifunctional ice-class patrol ship family that combines patrol ship, icebreaker, and tug roles for Arctic operations. Admiralty Shipyards built the Navy Arktika-code ships Ivan Papanin and Nikolay Zubov, while Vyborg Shipyard builds the modified Ermak-code FSB Border Service ships Purga and Dzerzhinsky; the design is attributed to Almaz Central Marine Design Bureau.

Role in Conflicts

Side
Russia

During the 2014 Russia-Ukraine War, Ukrainian forces reportedly struck the Project 23550 patrol icebreaker Purga at Vyborg Shipyard on 25 March 2026 while the vessel was under construction for Russia's FSB Border Service. Sources support conflict-related damage to the Russian vessel, not operational combat use by a commissioned Project 23550 ship.

Carried Missiles And Boats

Project 23550 sources describe a patrol-icebreaker hull with aviation and boat facilities plus a possible containerized missile fit rather than a conventional frigate-style vertical-launch battery.

Carried itemItem typeCarriage evidence
Kalibr, Sea-launched cruise missile family, MunitionsKalibrContainerized cruise missile family

Naval News describes the class as able to carry a containerized Kalibr-K / Kalibr-family missile module, while other reporting treats the missile fit as optional or mission-dependent.

Arctic Mission Fit

Project 23550 is reported as a military patrol icebreaker rather than a front-line surface combatant. The recurring public descriptions emphasize Arctic patrol endurance, ice navigation, towing and rescue tasks, aviation facilities, carried boats, and optional containerized weapons.

Hull role

Patrol ship, icebreaker, tug, and support vessel functions in Arctic waters.

Aviation

Flight deck and hangar reported for a Ka-27-class helicopter and unmanned aircraft support.

Boats and modules

Sources describe high-speed boats, a Project 23321 hovercraft option, and mission containers including possible Kalibr-family missile modules.

Built for border-guard and coast-guard work, the small aluminium-hulled craft carries heavy machine-gun armament, simple navigation or surface-search radar, and enough speed for short-range littoral security rather than open-ocean combat. Ukrainian Sea Guard and Navy examples remained visible after independence, and several Project 1400M boats entered the Russia-Ukraine War record as captured or destroyed Ukrainian maritime-security craft in 2022.

It put a PT-76-derived 76 mm turret, a BM-14-17 rocket launcher, automatic cannon, machine guns, and mine rails on a compact shallow-draft hull, making it a fire-support and patrol craft rather than an oceangoing combatant. Russian Shmel boats were documented in the Kerch and Sea of Azov security context during the Russo-Ukrainian War, while Ukrainian Sea Guard Dzhmil examples survived in Danube-area service and training.

Its Russia-Ukraine War record is best documented as Black Sea patrol and loss/capture evidence: Ukrainian Donbas was reported seized at Mariupol in April 2022, while a Russian Project 205P/Tarantul boat was reported sunk at Sevastopol after late-December 2023 Ukrainian strike activity.
