Operation Sea Guardian is NATO’s maritime security operation in the Mediterranean and is presently conducting three maritime security tasks: maritime security capacity building, support to maritime situational awareness and maritime counter-terrorism.
The world’s seas and oceans are of paramount importance in today’s globalised economy as 90 per cent of all traded goods are carried by sea, and communication cables on the sea-bed carry 95 per cent of the world’s cyberspace traffic. The Mediterranean Sea is no exception. Similarly, concerning energy, some 65 per cent of the oil and natural gas consumed in Western Europe passes through the Mediterranean.
In this context, NATO launched Operation Sea Guardian in the Mediterranean Sea. It is the successor to Operation Active Endeavour, NATO’s Article 5 operation in the Mediterranean that was launched in response to the 9/11 terrorist attacks against the United States in 2001. Operation Active Endeavour had helped deter terrorist activity in the Mediterranean Sea and secure one of the busiest trade routes in the world.
Operation Sea Guardian is not an Article 5 operation as Operation Active Endeavour was. It aims to establish maritime situational awareness, support counter-terrorism efforts, including through the hailing (and potentially boarding) of suspect vessels, and contribute to capacity-building for partners.
Operation Sea Guardian contributes to enhanced maritime security across the Mediterranean together with partner countries and other international organisations. NATO continues to cooperate through dialogue at the staff-to-staff level on operational cooperation with the European Union, notably in the framework of annual conferences on “Shared Awareness and De-confliction in the Mediterranean” co-chaired by the EU-led operation EUNAVFOR MED IRINI and Allied Maritime Command. Operation Sea Guardian also allows non-NATO countries to contribute as operational partners.
Operation Sea Guardian operates in the Mediterranean and performs the following three maritime security operation (MSO) tasks.
If agreed by the North Atlantic Council, Operation Sea Guardian can perform four additional MSO tasks:
Allies and partners can contribute to the operation in different ways: through “direct support” by placing assets under NATO operational command, and “associated support” with assets that remain under national command. Operation Sea Guardian is under the operational command of Allied Maritime Command in Northwood, United Kingdom, which serves as the Alliance’s hub for maritime security information sharing.
Every year, Operation Sea Guardian conducts five to six focused operations in specific areas of interest in the Mediterranean. These operations use sea, air, sub-sea and other assets, to gather, develop and maintain an accurate picture of daily activity in different parts of the Mediterranean Sea. In this context most focused operations conducted under Operation Sea Guardian also includes port visits to non-NATO countries.
