Blockade
Fourteen nations contributed ships and patrol aircraft to the operation. At any given time, 22 ships and 8 aircraft were enforcing the blockade, with ships from Standing Naval Force Atlantic and Standing Naval Force Mediterranean establishing a rotating duty. (Belgium, Canada, Denmark, France, Germany, Greece, Italy, the Netherlands, Norway, Portugal, Spain, Turkey, the U.K., and the U.S.), and eight maritime patrol aircraft, were involved in searching for and stopping blockade runners. Most contributors to the operation supplied one or two ships. The Turkish Navy, for example, participated with frigates, submarines, and tankers.
The operational area was divided into a series of "sea boxes", each the responsibility of a single warship. Each boarding team was composed of a "guard team" to board and wrest control of the target ship, and a "search team", to conduct the search.
The ships were authorized to board, inspect, and seize both ships seeking to break the blockade and their cargo. The Combined Task Force 440 was commanded by Admiral Mario Angeli of Italy. It marked the first time since its founding in 1949 that NATO was involved in combat operations.
