Established in March 2004, CTF 152 is one of three task forces operated by Combined Maritime Forces (CMF). CTF 152 enhances regional naval cooperation in the Arabian Gulf, especially between GCC nations.
CTF 152 operates in the Arabian Gulf where it coordinates Theatre Security Cooperation (TSC) activities with regional partners, conducts Maritime Security Operations (MSO), and remains prepared to respond to any crisis that may develop.
The Task Force also operates to protect key maritime infrastructure, including oil platforms, from a terrorist threat. CTF 152 operations influence events ashore as terrorist groups and others seeking to undermine maritime security or conduct other unlawful activity are denied the freedom to conduct activities to further their cause.
The Arabian Gulf is a 989 kilometer-long inland sea that separates Iran from the Arabian Peninsula. Countries with a coastline on the Arabian Gulf include Iran, United Arab Emirates, Saudi Arabia, Qatar, Bahrain, Kuwait and Iraq.
Today the Arabian Gulf is one of the most strategically important waterways in the world due to its importance in world oil transportation. It contains in the region of 813 billion barrels of proven oil reserves, representing nearly half of the world’s oil, and over 2,800 trillion cubic feet of natural gas reserves (42.5% of the world total). Arabian Gulf countries maintain about one-third of the world’s productive oil capacity. The majority of the oil exported from the Arabian Gulf is transported by sea.
CTF 152 consists of ships, aircraft and personnel from a range of nations including Saudi Arabia, Bahrain, Jordan, Qatar, Kuwait, UAE, UK and U.S, and has also included participation from Italy and Australia. Command of CTF 152 is rotated between participating nations on a three to twelve month basis.
