Patrol ship of the Russian Black Sea Fleet

In August 2013, "Ivanovets" underwent major repairs in drydock.

She subsequently tracked NATO ships at sea and made a voyage to Syria. 
In 2020, the ship carried out patrols near the Ukrainian offshore drilling platforms belonging to the Chornomornaftogaz company.
On 21 July 2023, during training exercises in the northwestern part of the Black Sea, "Ivanovets" sank the with an anti-ship cruise missile. "Ternopil", captured by Russia in 2014 during the annexation of Crimea by the Russian Federation, was used as a live-fire practice target. 
During the Russian invasion of Ukraine on 1 February 2024, "Ivanovets" was attacked by Ukrainian forces using MAGURA maritime drones. The vessel sustained severe damage to her hull from the detonations from anti-ship missiles and sunk. Although Russia claims the crew was evacuated, the Russian defense ministry did not comment on reports of the ship sinking. The attack took place from Donuzlav and from the village of Okunevka on the Black Sea coast. According to the main Intelligence Directorate of Ukraine, the loss of the boat cost Russia between 60 to 70 million.
