On 17 October 2014, Combined Joint Task Force – Operation Inherent Resolve was formally established by the Department of Defense in response to ongoing military actions against the rising threat posed by the Islamic State of Iraq and Syria (ISIS). Spawn from al Qaeda in Iraq after U.S. forces departed Iraq on 15 December 2011, ISIS rose to power and claimed to have an Islamic caliphate throughout the region. By June 2014, the security situation in Syria and Iraq had severely deteriorated with the Iraqi cities of Mosul and Tikrit falling into ISIS hands.
During the operation, U.S. Navy ships and assets deployed to the Arabian Gulf in the U.S. fleet area of operations and provided maritime security and support. While in the region, ships and strike groups conducted missions to annihilate the Islamic state group as well as reassure U.S. allies and partners, preserve freedom of navigation, and maintain the free flow of commerce.
By July 2017, CJTF-OIR coalition, Syrian and Iraqi partnered forces made enormous progress against ISIS ambitions. The cities of Mosul and Tikrit have been liberated, and coalition forces defeated insurgent counterattacks and reclaimed thousands of square kilometers. By 2019, the footprint of ISIS had all but been eliminated in Iraq and Syria.
Operation Inherent Resolve is still ongoing. Information will be added as it becomes available.
