Europe is intensifying maritime security through a refreshed Maritime Security Strategy, a €347 million subsea infrastructure package, and an €92 million ocean-observation initiative, funded by mechanisms like SAFE and the European Defence Fund, with the latter allocating substantial shares to France, Germany, Italy, and Spain.

Russia’s war in Ukraine and related threats are driving EU spending, including measures against a shadow fleet of sanctioned tankers and disruption to Baltic cables, prompting security actions such as the Cable Security Action Plan and NATO Baltic Sentry patrols.

By March 2026, the EU rolled out an Industrial Maritime Strategy to boost competitiveness, resilience, and sustainability, alongside a Counter-Drone Action Plan targeting unmanned maritime drones and counter-drone capabilities across air, surface, and underwater domains.

The report outlines an integrated industry framework with chapters on market analysis and production, signaling a comprehensive approach rather than a single narrative.

Spain participates in Europe’s core naval industry circle but contends with structural and market hurdles in converting export potential into intra-EU orders and larger-scale contracts.

Commentary from policy experts argues that industrial concentration alone does not equate to military commitment, noting concerns about lack of broader regional engagement.

Submarine cables carry the vast majority of intercontinental internet traffic and also support electricity interconnectors, so disruptions have wide-reaching consequences beyond the immediate damage site.

Critics stress that high industrial concentration does not reflect true military commitment, pointing to Greece and Sweden as important but underrepresented contributors who highlight the need for credible, interoperable, and distributed forces with broader burden-sharing.

Other critiques argue the four-country focus omits vulnerable navies and emphasize inclusion of nations like Greece, Sweden, and potentially the UK and Norway to broaden a shared maritime security picture.

Denmark’s upcoming decision on its frigate winner by year-end keeps Navantia in play, illustrating ongoing competition among major European shipyards and potential shifts in leadership.

There is a clear call to move from strategy to action by building sensing, repair, and surveillance capabilities to protect critical undersea infrastructure.

Experts advocate a Europe-wide, interoperable system with a shared maritime picture and integrated information-to-action networks to monitor and defend underwater assets.
