[1] The Kashtan CIWS on the first ship was replaced in subsequent vessels by 12 Redut VLS cells containing 9M96E medium-range SAMs of the S-400 system.

[2] The export version known as Project 20382 Tigr carries either eight supersonic SS-N-26 (P-800 Oniks) anti-ship missiles or sixteen subsonic SS-N-25 'Switchblade' (Kh-35E Uran).

During the exercise, the ships conducted artillery fire at sea and air targets, found and destroyed a simulated enemy submarine, and practiced joint maneuvering.

[12] On 31 August, during an exercise, the corvette crew repulsed a simulated torpedo attack in the Baltic Sea, and also conducted artillery firing at various targets, anti-sabotage defense measures, and an in-ship training to combat ship damage.

[13] On 18 June 2018, a detachment of ships of the Baltic Fleet, consisting of Boikiy and Stoikiy, the tanker Kola and the tugboat Viktor Konetsky, sailed into the North Atlantic to carry out planned tasks for a long voyage.

[15] On 16 December 2020, corvette Stoikiy, tanker Kola and tug Yakov Grebelskiy left Naval Base Baltiysk for Atlantic, Mediterranean and Indian Ocean.

[18] On 15 January, they met frigate Admiral Kasatonov and tug Nikolay Chiker in the western Mediterranean Sea.

At the time of the incident, maritime tracking website Vesselfinder.com temporarily misidentified Kola as Stoikiy (specifically "Russian Warship 545"); this was corrected on 25 March.

[35] In late November, both corvettes were absent from Tartus, likely shadowing French aircraft carrier, deployed to the East Mediterranean.

[37] In April 2023, the corvette, accompanied by Soobrazitelny and the frigate Admiral Grigorovich, was reported to have left the Mediterranean, transitting via the Atlantic to the Baltic.
