The submarine destroyer (BPK) Severomorsk on August 13, 2011 began escorting the caravan of three merchant ships under the flags of Cyprus, Liberia and Panama, the Northern Fleet press service said.
The dry cargo carrier Valdai and the tanker Zaliv Anadyr have Russian crew on board.
For the Severomorsk this is the ninth convoy. Since its arrival in the Gulf of Aden the Russian warship has escorted 31 cargo ships of different states through the piracy infected area.
