The ship is equipped with a newly designed Zvezda-1 integrated sonar system (with NATO reporting name Ox Tail) as its primary ASW sensor.

[1] After the collapse of the Soviet Union the project was frozen and only one ship, Neustrashimy (Неустрашимый - "Dauntless"), was in active service with the Russian Baltic Fleet by the mid-1990s.

[citation needed] In late September 2008, Neustrashimy left the Baltic Fleet and was sent to the Gulf of Aden waters off the Somali coast to fight piracy in the region.

Russian navy spokesman Captain Igor Dygalo told the Associated Press that the missile frigate Neustrashimy had left the Baltic Sea port of Baltiysk a day before the hijacking to cooperate with other unspecified countries in anti-piracy efforts.

In June 2016 Yaroslav Mudry was part of a maritime incident between Russian and United States navies in which the ship came in close proximity to USS Gravely in the Mediterranean, though both sides claim the other was at fault for the encounter.

[5] In April 2018, Yaroslav Mudry and Uda-class oiler Lena were escorted by the Royal Navy frigate HMS St Albans as they were passing through the English Channel en route to the Mediterranean Sea.

On 21 October, the frigate under the command of Captain 2nd rank Mikhail Navolotsky paid a visit to the Cypriot port of Limassol[8] and, in early December, patrolled the Gulf of Aden.

In April 2016, the director of the Yantar shipyard announced the incomplete hulk was to be scrapped as the high cost of completing the ship to an outdated design was considered inefficient and the space freed up by its disposal could be employed on more cost-effective projects.
