Operation Aspides, also known as EUNAVFOR Aspides, is an EU military operation in response to Houthi engagements with international shipping in the Red Sea. Named after the Greek word for shields, Operation Aspides—unlike the US-led Operation Prosperity Guardian—is a "purely defensive" mission to increase maritime surveillance in the region, provide escort to merchant vessels, and defend against strikes.

Background
Since the start of the Israel–Gaza war, the Houthi movement has engaged with and boarded certain ships passing through the Red Sea, as a response to the Israeli attacks in Gaza and the rest of Palestine since October.
Since the beginning of the conflict, at least four EU country-flagged ships have been struck by the Houthis.
Mission
On 8 February 2024, EU member states took a decision in the Council of the European Union to start Operation Aspides, which was to begin on 19 February and last one year, with its base of operations being in Greece and with a Hellenic Navy officer being in charge of operations.
According to the European External Action Service, the purpose of the operation is to protect merchant vessels against strikes, to accompany them and to reinforce maritime situational awareness in the region. 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. The mission is instructed to coordinate closely with Operation Atalanta, another EU-led naval mission in the wider region.
Force structure
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. The European External Action Service has indicated that 130 staff officers will be based in the operational headquarters.
On 22 February, the Government of Sweden announced that Sweden would be sending some military personnel to participate in Operation Apsides. Sweden will initially send four staff officers with the possibility to increase the number to ten. 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. On 28 March, the government of Estonia announced that one member of the Estonian Defence Forces will participate in the operation.
The Force Commander in the Red Sea is Italian Rear Admiral Stefano Costantino, based on the Italian destroyer Caio Duilio.
