Overview

The 624th Regional Support Group is a United States Air Force Reserve organization headquartered at Joint Base Pearl Harbor–Hickam, Hawaii. It is one of two Air Force Reserve groups stationed in the Pacific Area of Responsibility and reports directly to Fourth Air Force at March Air Reserve Base, California. Rather than being a consumer-facing commercial brand, the group is a military support formation whose identity represents a coordinated set of personnel, logistics, medical, civil-engineering, and aerial-port capabilities. The group was established as the 624th Regional Support Group on October 15, 2001, and activated on January 1, 2002. Its creation followed a reorganization of resources associated with earlier regional support structures, particularly the 604th Regional Support Group and related units. The reorganization changed the designations and assignments of several existing components while bringing aerial-port, medical, engineering, and personnel-support functions under the new 624th organization. The group’s stated organization includes a headquarters, four squadrons, and an aeromedical staging flight operating at Hickam and Andersen Air Force Base, Guam. The 44th Aerial Port Squadron at Andersen processes and loads personnel and cargo for United States Air Force aircraft and Civil Air Reserve Fleet operations. The 48th Aerial Port Squadron at Hickam can augment fixed aerial-port facilities or conduct stand-alone air-terminal operations. Its responsibilities include aircraft loading, cargo processing and inspection, passenger services, fleet servicing, and aerial-port command and control. These capabilities support exercises, contingency operations, unit movements, humanitarian relief, disaster response, and other worldwide missions. Medical readiness is provided by the 624th Aeromedical Staging Squadron and the 624th Aeromedical Staging Flight at Andersen. Their functions include maintaining trained personnel and equipment for patient movement, supporting aeromedical staging facilities, and deploying qualified medical staff when required. The organization also includes the 624th Civil Engineer Squadron, whose Prime Base Engineer Emergency Force, firefighting, and readiness teams can deploy to construct or maintain airfield facilities, provide fire protection, and assist with disaster planning and response. The Directorate of Personnel Management provides military personnel services to Reserve members and the retired military community. Collectively, the group’s functions support both peacetime readiness and expeditionary operations. Its personnel and component units may be called upon for military exercises, operational deployments, humanitarian assistance, disaster response, and the broader requirements of Air Force mobility and support missions. The group remains assigned to Fourth Air Force, with its principal station at Hickam, now part of Joint Base Pearl Harbor–Hickam.

History

The 624th Regional Support Group was established on October 15, 2001, and activated on January 1, 2002. Its formation was part of a reorganization of Air Force Reserve support resources in the Pacific. The new group emerged from the transformation and redistribution of personnel and components associated with the 604th Regional Support Group and other predecessor organizations. The reorganization replaced or redesignated several existing units. At Hickam, the 604th Aeromedical Staging Squadron became the 624th Aeromedical Staging Squadron, the 604th Logistics Support Flight was redesignated as the 624th Logistics Support Flight, and the 704th Civil Engineer Squadron became the 624th Civil Engineer Squadron. The 48th Aerial Port Squadron at Hickam and the 44th Aerial Port Squadron at Andersen Air Force Base, Guam, were transferred into the new group. At Andersen, the former operating location of the 604th Aeromedical Staging Squadron was replaced by an aeromedical staging flight and a logistics support flight associated with the new structure. The group has remained assigned to Fourth Air Force since its activation. Its principal station has also remained Hickam Air Force Base, which later became part of Joint Base Pearl Harbor–Hickam. The organization’s geographic position gives it a role in supporting Air Force Reserve activities across the Pacific Area of Responsibility while retaining the ability to deploy personnel and capabilities beyond the region. The 624th Regional Support Group’s history is defined less by commercial product development than by changes in military organization and mission readiness. Its component units provide complementary capabilities. Aerial-port personnel handle aircraft, cargo, passengers, and terminal operations. Aeromedical personnel prepare for and conduct patient movement and staging functions. Civil engineers provide emergency construction, airfield support, firefighting, and readiness assistance. Personnel-management staff serve Reserve members and retirees. These capabilities are maintained for peacetime training as well as wartime, contingency, exercise, humanitarian-relief, and disaster-response requirements. The group’s medical and engineering units can deploy qualified personnel and specialized teams, while its aerial-port squadrons can either reinforce established facilities or operate independently. The available reference material identifies the 624th Aeromedical Staging Squadron, 624th Civil Engineer Squadron, 44th Aerial Port Squadron, and 48th Aerial Port Squadron as continuing components. The 624th Logistics Support Flight and related Andersen logistics flight are listed in the historical lineage, but their later status is not clearly established in the supplied material.
