Spanish Navy Monitors Transit of Russian Attack Submarine

Maritime Executive – The Spanish Navy is reporting that it tracked a Russian attack submarine entering the Mediterranean and accompanied for part of the trip by a Russian tug.

The Balearic-Strait-Canaries Axis and Spanish Maritime Strategy​

Center for Maritime Strategy – On November 30th, 2023 the Spanish Navy (“Armada Española”) received the S-81 Isaac Peral, the first of four diesel-electric attack submarines of the S-80 Plus class, built by Spanish shipbuilder Navantia. The S-80 program is expected to revive the Navy’s diminished submarine fleet by 2028 and significantly enhance Spain’s maritime surveillance and area denial capabilities. The S-80-class submarines come at a time when the Spanish Navy is under-resourced to meet the strategic requirements and threats imposed by its current maritime environment.

Spain’s submarine fleet is beginning to regain operational capacity a year after the serious accident aboard the Tramontana in which water began infiltrating the hull while it was 300m deep and 15 nautical miles off the coast of Cartagena. The crew were able to get the submarine back to port. The incident led to the temporary withdrawal of the four submarines of the Agosta-class in order to review them.
