Russian forces in the Mediterranean - Wk10/2021

Task force composition

As reported by OSINT on the morning of March 14

Weekly Brief

Russian naval forces inside the Mediterranean have been substantially reinforced with the arrival of the Improved Kilo Class submarine RFS Rostov-on-Don on the afternoon of March 07 and the return of the frigate RFS Admiral Grigorovich and patrol vessel RFS Dmitri Rogachev from their Indian Ocean deployment. Another change in the task force composition is the arrival of the small tanker RFS Iman and the departure of the rescue tug SB-739. It is unusual for these rescue tugs to leave the Mediterranean without escorting a warship. 
The fact that the patrol vessel RFS Dmitri Rogachev was refueling from the sea tanker RFS Vyazma the day after it passed through the Suez Canal, rather than from the SB-739, might suggest that SB-739 has encountered mechanical problems which prevents her from supporting warships. RFS Iman could thus be deployed to the Mediterranean to take over the escorting duties of SB-739.

With the Us Navy Dwight D. Eisenhower carrier strike group operating in the eastern Mediterranean [a], naval activity of Russian task force is expected to remain high with Russian warships monitoring the movements of the US carrier group.

Commercial satellite imagery detected the rescue tug Nikolay Chiker, Kaliningradneft class sea tanker RFS Vyazma and Bykov class patrol vessel RFS Dmitry Rogachev at anchor near Port Said, Egypt [5]. RFS Dmitry Rogachev is moored alongside RFS Vyazma, suggesting that the vessel is being refueled by the tanker.

The AIS signal of rescue tug SB-739 was last recorded southeast of Rhodes, Greece with the vessel heading northwest towards the Aegean Sea [6].
