Twenty-First Air Force
The Twenty-First Air Force (21 AF) is an active numbered air force of the United States Air Force. It was re-activated on September 5, 2025 during a ceremony hosted at Joint Base McGuire-Dix-Lakehurst. It had been inactive since 2012, when it was previously designated as the 21st Expeditionary Mobility Task Force (21 EMTF), headquartered at the McGuire AFB entity of Joint Base McGuire–Dix–Lakehurst until its inactivation in 2012. In this capacity, it was subordinate to Air Mobility Command's Eighteenth Air Force.
First created as a wing of the United States Army Air Forces during World War II, the unit initially ferried aircraft, but its mission soon changed to airlifting personnel and cargo.
The organization was redesignated several times, eventually becoming the Twenty-First Air Force in 1966.
In 2003, the unit was redesignated as the 21st Expeditionary Mobility Task Force, assuming responsibility for worldwide airlift operations in support of United States Joint Forces Command, United States European Command, and United States Central Command.
In 2012, the organization was inactivated, with its subordinate units and responsibilities being transferred to the United States Air Force Expeditionary Center.
The 21st Expeditionary Mobility Task Force (EMTF) provided a rapid, tailored, worldwide, air mobility response to combatant commander's needs. Reporting through Eighteenth Air Force, the EMTF extended existing AMC infrastructure, through both en route employment and rapid forward deployment capabilities.
Its mission was to command and assess the combat readiness of assigned air mobility forces over the Atlantic half of the globe in support of Global Reach. These forces were at more than 55 locations in eight countries. 21 EMTF's major units included six active duty wings, two operational flying groups, and two mobility operations/support groups. Additionally, the 21 EMTF was liaison to 40 Air Reserve Component Wings.
21 EMTF's strategic airlift force included the C-5 Galaxy, C-17 Globemaster III and the C-130 Hercules, aircraft, used to move cargo and passengers worldwide. The tanker force included KC-10 Extenders and KC-135 Stratotankers used for inflight refueling to provide increased global mobility.
