Under Operation Active Endeavour, NATO ships are patrolling the Mediterranean,
monitoring shipping and providing escorts to non-military vessels through
the Straits of Gibraltar to help detect, deter and protect against terrorist
The operation has evolved out of NATOs immediate response to the
terrorist attacks against the United States of 11 September 2001.
The NATO Standing Naval Force Mediterranean and Standing Naval Force
Atlantic rotate on a three-monthly basis in Operation Active Endeavour.
Some NATO nations, mainly Greece, Italy, Spain and Turkey, contribute
directly to the operation with naval assets. Escort operations in the
Straits of Gibraltar involve the use of fast patrol boats from Northern
European Allies Denmark, Germany and Norway. Spain also provides additional
assets in the Straits. Operation Active Endeavour relies heavily on
the logistic support of Mediterranean NATO Allies. Russia and Ukraine
have also offered support and the modalities of their participation
are being finalised.
