Operation Aspides: How the European Union protects merchant ships in volatile maritime zones
In short: In response to Houthi attacks on international shipping, the European Union launched a defensive naval mission named after the Greek word for shields. Operating across critical waterways from the Red Sea to the Persian Gulf, this coalition provides armed escorts to merchant vessels while reinforcing regional maritime situational awareness.
Formally established in February 2024, Operation Aspides maintains a strictly defensive mandate, distinguishing it from other international efforts in the region. Headquartered in Larissa, Greece, the mission is led by Rear Admiral Vasileios Gryparis. The operational area is expansive, covering the Bab al-Mandab Straits, the Strait of Hormuz, and the surrounding international waters of the Arabian and Red Seas. The mission relies on a rotating force of ships and a dedicated staff of 130 officers at its headquarters to coordinate protection for commercial traffic.
The operational reality involves constant vigilance against drones, missiles, and uncrewed surface vessels. Since its inception, participating frigates and destroyers from nations including Germany, Greece, Italy, France, and the Netherlands have engaged in numerous defensive actions. These range from intercepting incoming projectiles to conducting rescue operations for crews of struck merchant vessels. For instance, in August 2024, the French frigate Chevalier Paul rescued the crew of the tanker Sounion while simultaneously neutralizing an approaching explosive boat.
The mission has faced logistical and technical hurdles, including equipment failures that delayed the deployment of certain vessels. Despite these challenges, the coalition has demonstrated resilience, with command rotating between various European naval officers and flagships. Initially set for a one-year duration, the Council of the European Union extended the mandate in February 2025, ensuring the operation remains active through February 2026. As regional tensions evolved, the mission has adapted, with France announcing additional support in March 2026 to bolster security in the Strait of Hormuz.
The effectiveness of the operation is measured by its ability to maintain the flow of trade despite persistent threats. By providing a visible naval presence and active defense, the EU aims to secure vital maritime lanes. The coordination between Aspides and other regional naval missions underscores the complexity of maintaining stability in these high-stakes waters, where a single incident can necessitate rapid, multi-national responses to protect both civilian lives and global supply chains.
