Menorca becomes a naval base for the NATO fleet, the third in Spain after Rota and Cartagena. Maó has more modest military facilities, whose origins date back to the British occupation of the island in the 19th century.

The cost of Spanish participation in this operation exceeds 27 million annually. The most important role, however, belongs to American destroyers stationed at the Rota naval base, which are part of the Atlantic Alliance Response Force (NRF) In 2024, Spain is expected to contribute a submarine, a maritime surveillance plane, a frigate and a supply ship.
