Russian Navy vessels in Algiers on 21 April 2025 - Analysis of GEOINT

Spectacular SAT image of Algiers. It looks like they have placed an anti-intrusion barrier.

If so, it would be the first time that a naval asset of the RFN in port has feared being attacked.

This is the first time a RFN submarine has been in a foreign port since the loss of the Naval Base in TARTUS, Syria.

At the moment it is not confirmed that it is an anti-intrusion barrier, in fact it could also be an anti-pollution barrier.

If so, we can say that the submarine has refueled.

I do not have the expertise to say if a refueling in a commercial port is possible for a submarine, but as is known, the Algerians have the ability to manage kilo-class submarines as they also have them.

We will look into this in other posts to understand what that barrier is.

The barrier is shown in the red dotted box, while the anchor point of the barrier to the pier is highlighted in yellow.

The Krasnodar submarine and the Eugeny Tchurov rescue tug, stopped at the port of Algiers from 20 to 24 April so the images analyzed confirm those already inserted in the previous posts.

These are some anti-intrusion barriers used in the port of Algiers.

Conclusions, we can not confirm anything for the moment if we had a confirmation with other images we could say if intrusion or pollution. I hope someone can add more info on this.
