6th NATO Operation Sea Guardian Focused Patrol of 2021 is Underway

On 29 October, a NATO task group set sail in the Mediterranean Sea as part of NATO’s maritime security operation, Operation Sea Guardian (OSG).

The Hellenic Navy frigate HS Spetsai (flagship) and the Bulgarian Navy frigate BGS Drazki are being supported by submarines from Greece and Turkey. Aircrafts from Greece, Turkey and US will also support to the patrols.


The sixth and the last focused patrol of the year, includes a planned port visit to Haifa, Israel and Alexandria, Egypt. In conjunction with these visits, NATO will deploy a mobile training team from Greece to provide training to Israeli and Egyptian Navies. This activity aims to improve regional maritime situational awareness and to solidify NATO partnerships with Israel and Egypt.


This focused patrol also coincides with the 5th anniversary of NATO ships first starting to conduct Operation Sea Guardian in November 2016.
