The Project 1144.2 cruiser Pyotr Velikiy was fielded by Russia in the 2011 Syrian Civil War as part of the Admiral Kuznetsov-led Northern Fleet task force. TASS reported that the task force, including Admiral Kuznetsov, Pyotr Velikiy, Severomorsk, Vice-Admiral Kulakov, Black Sea Fleet warships, support vessels, and deck-based aircraft, performed missions in Syria from 8 November 2016.
A later TASS factbox states that Pyotr Velikiy and Admiral Kuznetsov participated together in a long-range combat mission in the Mediterranean off Syria from October 2016 to February 2017. USNI News also identified Pyotr Velikiy in the Northern Fleet group moving to the Eastern Mediterranean to take part in the war in Syria.

Timeline
The clearest sourced sequence begins in October 2016, when Pyotr Velikiy sailed with Admiral Kuznetsov and escorts toward the Eastern Mediterranean. By November 2016, Russian reporting placed the task force in missions connected to Syria, while carrier-based aircraft from Admiral Kuznetsov conducted the documented strike activity.
By early 2017, Russian sources described the ships as returning from the Mediterranean after the Syrian mission. The available sources identify Pyotr Velikiy as a fielded cruiser and escort in the task force, not as a ship whose own P-700 Granit, air-defense, artillery, or anti-submarine weapons were fired against Syrian-war targets.

Narrative
Pyotr Velikiy's Syrian-war role was tied to Russia's naval show of force around Admiral Kuznetsov. The cruiser provided a visible heavy surface-combatant escort to the carrier group, which moved from the Northern Fleet toward the Eastern Mediterranean during Russia's intervention on behalf of the Syrian government.
The strike element documented in the same reporting was the carrier air wing. TASS attributed the first Russian Navy carrier-based combat missions and hundreds of sorties to deck-based aircraft, while GlobalSecurity's account quotes Russian defense reporting that Su-33 aircraft began operating from Admiral Kuznetsov against targets in Idlib and Homs. That distinction keeps Pyotr Velikiy's entry in this conflict as deployment, escort, force-protection, deterrence, and symbolic naval presence rather than confirmed direct fires.
FPRI's assessment of Russian naval forces in the Syrian war describes Russia's Mediterranean naval presence as gaining a new purpose after Moscow's direct intervention in Syria and highlights the conventional deterrence role of the Mediterranean Squadron. Pyotr Velikiy's deployment fits that pattern as a high-profile Northern Fleet contribution to the Syrian-war naval posture.
