The Russian tanker Kama, two Steregushchiy class corvettes, an Admiral Grigorovich class frigate, and two Karakurt class corvettes are reportedly operating in the North Sea.

The Russian ship Kama left its port of assignment on 4 January 2023, crossed the English Channel on 12 January, and then passed the Azores on 25 January under the surveillance of the Portuguese Navy on its way south.

It is possible that she made a diversionary move because after reaching the middle of the Atlantic Ocean towards South America, she finally diverted her course toward South Africa.

After a stop in Cape Town, she circled Africa via its south-eastern coast and headed back towards the Bab al Mandab Strait. After a wait, it crossed the Suez Canal in April but then turned back for a visit to Saudi Arabia.
