Moma-class intelligence ships are documented in the Syrian Civil War as Russian naval intelligence and surveillance assets rather than strike platforms. USNI News reported that the signals-intelligence ship Liman had recently returned from the Mediterranean, where it supported Russian operations in and around Syria, before it sank after a collision near the Bosporus on 27 April 2017.
The same class remained visible around Syria in later reporting. The Associated Press reported that Kildin, a Russian spy ship carrying intelligence-gathering equipment, caught fire and drifted off the Syrian coast on 23 January 2025. AP also reported that military officials said the ship regained control and was still stationed and gathering intelligence off Tartus, accompanied by a frigate and a supply vessel.

Timeline
The clearest dated public milestone is Liman's April 2017 loss, because USNI tied that incident to the ship's recent Mediterranean support for Russian operations in and around Syria. The report placed the intelligence ship in the broader Russian naval effort that supplied and supported Moscow's intervention from the sea.
On 23 January 2025, Kildin was documented off Syria when AP obtained radio audio, video, and photos of the ship after a fire. The report described Kildin as gathering intelligence on NATO activity in the Mediterranean and, after the incident, still gathering intelligence off Tartus.

Narrative
The Moma-class role in Syria was maritime intelligence support. KCHF identifies Kildin as a Project 861M Moma-class electronic-intelligence ship converted from a survey vessel, while RussianShips.info lists Kildin and Liman among Project 861M medium intelligence ships. Those class references align with the conflict reporting that describes Liman as a signals-intelligence ship and Kildin as a spy ship packed with intelligence-gathering equipment.
The evidence supports surveillance, intelligence collection, and operational support around the Russian naval presence at Tartus. USNI separately reported in January 2017 that Russia and Syria had agreed to expand the Tartus naval facility and described the site as a key hub for Russian support to Bashar al-Assad. The Moma-class evidence does not show direct kinetic employment, missile launches, or shipboard weapons use in Syria.
Public sourcing is hull-specific rather than class-wide: Liman is tied to recent support for Russian operations in and around Syria, and Kildin is tied to intelligence gathering off Tartus. Together they establish the class's documented conflict use as Russian naval reconnaissance and electronic-intelligence support.
