On 9 September the ship fired 86 rounds from her 130 mm guns in support of the defenders of the Oranienbaum Bridgehead. On 10 and 12 September, "Grozyashchy" laid 54 mines and 90 mine defenders in Luga Bay and nearby areas. On the latter day, her propellers were damaged after they struck a reef and had to go to Kronstadt for repairs. On 22–23 September the ship was hit three times by German bombs which started a large fire that had to be put out by flooding the drydock that she was in. "Grozyashchy" was further damaged by splinters from artillery shells detonating in the dock on 29 September. The cumulative effects knocked out her steering, put her aft-most 130 mm gun out of action and damaged much of her machinery in addition to killing seven crewmen and injuring twenty others. The ship was towed to Shipyard No. 189 for repairs on 3 October.
