Operation Aspides, also known as EUNAVFOR Aspides, is a European Union (EU) military operation in response to the Houthi attacks on international shipping in the Red Sea.^[2] In contrast to the US-led Operation Prosperity Guardian, EU officials have underlined the "purely defensive" nature of EUNAVFOR Aspides. The purpose of the operation is to provide escort to merchant vessels in the area, defend against attacks and increase maritime surveillance in the region. The name of the operation comes from the Greek word for shields.^[3]

Since the start of the Israel–Hamas war, the Houthi movement has been attacking and hijacking ships passing through the Red Sea, claiming to be in response to the Israeli counter-attack in the Gaza Strip after the 7 October, Hamas attack on Israel.^[4]

On 8 February, EU member states took a decision in the Council of the European Union to start Operation Aspides which is to begin on 19 February and last one year, with its base of operations being in Greece and in charge of operations being a Hellenic Navy officer.^[9][10]

The purpose of the operation is, according the European External Action Service, to protect merchant vessels against attacks, to accompany them and to reinforce maritime situational awareness in the region.^[11] It thus has a "purely defensive" mandate, something which has also been underlined by EU officials, in contrast to the US-led Operation Prosperity Guardian.^[12] The mission is instructed to coordinate closely with Operation Atalanta, another EU-led naval mission in the wider region.^[1]

The operational headquarters of EUNAVFOR ASPIDES is the Hellenic European Union Operational Headquarters (EL EU OHQ) in Larissa, Greece, led by the Operation Commander, Greek Commodore Vasileios Gryparis.^[13][1] The European External Action Service has indicated that 130 staff officers will be based in the operational headquarters.^[11]

Sweden will initially send four staff officers with the possibility to increase the number to ten.^[14][15] On 8 March, Finland made a decision to participate in the operation by sending a maximum of five soldiers with staff duties, in addition to dispatching up to two soldiers with similar responsibilities to Operation Prosperity Guardian.^[16] On 28 March, the government of Estonia announced that one member of the Estonian Defence Forces will participate in the operation.^[17]
