Direct proof of use
The Ka-52 appears in the 2011 Syrian Civil War through Russian Aerospace Forces combat helicopter operations that began in 2016. TASS, citing a Russian defense-industry source, reported on April 11, 2016 that Ka-52 and Mi-28N helicopters had started combat sorties in Syria and that the Ka-52 made its combat debut near Homs in early April.
The same TASS account said one Ka-52 was used against small militant groups with both unguided and precision weapons. It identified 80 mm S-8OFP unguided rockets and 9M120F Ataka guided missiles as weapons used during the first Ka-52 combat sortie, while also noting that the Russian Ministry of Defense had not officially confirmed the specific debut sortie.

Timeline
In early 2016, Russia deployed Mi-28N and Ka-52 attack helicopters to Hmeymim airbase in Latakia province for combat testing. TASS tied the first reported Ka-52 combat sortie to the Homs area in early April 2016, after Mi-28N use near Palmyra in late March.
CNA's review of the Russian air campaign describes attack helicopters as becoming more important after Islamic State attacks in desert areas around Palmyra, the Euphrates, and Deir ez-Zor in 2016-2017. It specifically lists Ka-52s among the involved Russian helicopter types and says the type tested Vikhr-M long-range guided missiles in Syria under day and night conditions.
RAND's study of Russia's Syria campaign places Ka-52 detachments in the broader forward-basing pattern for Russian rotary-wing forces. It says helicopter detachments rotated between Shayrat and Tiyas in Homs Province during the regime's 2016 counter-ISIS operations and lists Ka-52s with Mi-24/35 and Mi-28 detachments leading up to the recapture of Palmyra.

Narrative
The documented user was Russia, operating in support of the Syrian government and allied forces. The public sources used here support a fire-support and force-protection role rather than Syrian possession of the aircraft: TASS describes Russian deployment to Hmeymim and combat sorties near Homs, while RAND frames Ka-52 detachments as part of the Russian VKS rotary-wing network supporting counter-ISIS operations.
The best-supported combat role was attack-helicopter fire support against ground targets. TASS says the reported first sortie used S-8OFP rockets and 9M120F guided missiles because armored vehicles were not present in the area, and CNA later describes Ka-52 use for testing Vikhr-M missiles in the Syria campaign. RAND connects the rotary-wing basing pattern to the Russian shift toward close air support for Syrian government counter-ISIS operations in Palmyra, eastern Homs, and Deir ez-Zor.
The evidence does not establish a complete sortie count, order of battle, or target list for Ka-52 operations in Syria. It supports Russian fielding and combat use from 2016, identifies Hmeymim and Homs Province as early deployment and employment context, and shows continued Ka-52 relevance in Russian helicopter operations during the 2016-2017 phase of the campaign.
