Project 21980 Grachonok boats are documented in Russian service during the 2014 Russia-Ukraine War through Ukrainian Navy and Ukrainian General Staff reporting, as relayed by Ukrainian and defense outlets. On 29-30 April 2026, Ukrainian Navy reporting said vessels guarding the Kerch Bridge near the Kerch Strait were struck, including a Russian anti-sabotage vessel identified as Grachonok.
A second dated report from Ukrinform, citing Ukraine's General Staff, said Ukraine's Defense Forces struck a Project 21980 Grachonok anti-sabotage boat near Kaspiysk in Dagestan on 17-18 May 2026. The General Staff-linked report described boats of this type as assets used to protect naval bases and counter sabotage forces.

Timeline
The public record for this class in the war is clearest in 2026, when Ukrainian reports named Grachonok boats in maritime-security contexts around occupied Crimea and Russian naval facilities. The April Kerch Strait report placed the boat with Russian vessels protecting the Kerch Bridge, while the May Kaspiysk report linked another Project 21980 boat to naval-base protection in the Caspian Sea area.
The reports describe Ukrainian strikes against the boats rather than offensive employment by the boats themselves. Their conflict role is therefore best treated as Russian force protection, harbor and bridge security, and counter-sabotage work.

Narrative
The Grachonok class appeared in the maritime layer of the war as a small Russian security vessel built for anti-sabotage and base-defense work. Defense Express described the Project 21980 boat hit near the Kerch Bridge as a sonar-equipped vessel with an unmanned underwater vehicle and diving chamber, and said it was reportedly carrying out underwater-drone defense near the bridge.
The Kerch Bridge role fits the vessel's anti-sabotage design. Ukrainian Navy reporting, summarized by Ukrainska Pravda, said the hit vessels were part of a Russian flotilla near the Kerch Strait and were used to guard the Kerch Bridge and counter sabotage groups. UNITED24 Media separately reported that the Project 21980 boat was struck by Ukrainian naval drones near the bridge and described the class as intended for protecting naval bases and critical maritime infrastructure.
The later Kaspiysk report expanded the documented geography beyond the Kerch Strait. Ukrinform reported that the General Staff named a Project 21980 Grachonok boat among targets struck near Kaspiysk in Dagestan, while also noting the type's base-protection and counter-sabotage function. That claim supports fielding in the wider war context but does not by itself identify the individual hull or final damage state.
