A Hellenic Navy frigate participating in the EUNAVFOR “Aspides” mission to protect shipping in the Red Sea and Gulf of Aden will remain docked in a Djibouti port until Sunday for resupply, defense ministry sources in Athens said on Friday.

The EU military mission aims to protect vessels plying the specific sea lanes from the Iran-backed Houthi rebels operating in Yemen.

The Greek warship “Hydra” has been fitted with the Drone Dome anti-drome system and with a new electronic warfare system.

The Hydra is a German-made MEKO 200HN type frigate laid in a Hamburg shipyard in 1991 and presented to the Hellenic Navy in October 1992.

The latest attack against a vessel in the Gulf of Aden this past week claimed the lives of three sailors, as a missile or drone struck a bulker. Another 20 crew-members and three security guards on board the “True Confidence” were evacuated by an Indian navy warship to Djibouti.

The Barbados-flagged, American-owned and Cypriot-managed vessel was hit and set on fire on Wednesday as it was sailing some 50 nautical miles south of Aden.
