Marine Wing Support Group 47 (MWSG-47) was activated on 1 July 1962 at Naval Air Station Los Alamitos, CA. Its mission, to provide all aviation ground support for fixed and rotary wing units of the 4th Marine Aircraft Wing. The official designation was Marine Wing Support Group 47, Marine Air Reserve Training Unit, Marine Air Reserve Training Command, 4th Marine Aircraft Wing, U. S. Marine Corps Reserve. On 1 October 1965, the command was relocated to
Naval Air Station Twin Cities,
Minneapolis, MN. At the time, the Group was composed of two squadrons, Wing Engineer Squadron 47 (WES-47) and Wing Transportation Squadron 47 (WTS-47). These squadrons in turn comprised numerous detachments scattered across the United States. On 1 October 1977, MWSG-47 was again relocated; this time to
Selfridge Air National Guard Base,
Mt. Clemens, MI. Marines had been present at Selfridge since 20 April 1968, when the Marine Air Reserve Training Detachment (MARTD) supporting OV-10, UH-34 and CH-46 airframes arrived from its previous site a few miles downriver at
Naval Air Station Grosse Ile pending its closure in 1969. The MARTD was renamed a Marine Air Reserve Training Unit (MARTU) and still later it was re-designated as Headquarters & Ground Maintenance Squadron 47 (H&GMS-47), another squadron assigned to MWSG-47. At this time the Group comprised approximately 1105 Marines at five sites. In 1986, the Marine Corps began a reorganization of the aviation ground support (AGS) community. Marine Air Base Squadrons, up until then a part of the command structure of the Marine Corps Air Station, were transferred to the MWSGs. The MWSG was then restructured. The most significant change involved the creation of the Marine Wing Support Squadron. The mission of the new MWSS was to perform all of the AGS functions that were spread between the various squadrons that were being eliminated; the WES, WTS, MABS and H&GMS. Furthermore, the MWSSs were task organized to support either rotary wing (RW) or fixed wing (FW) flying squadrons. This change took additional time to complete in the Marine Corps Reserve, but by 1 October 1988 it was done and MWSG-47 comprised H&HS-47, MWSS-471(FW), MWSS-472(RW), MWSS-473(FW) and MWSS-474(RW). The Group had over 2500 Marines scattered across 14 sites. In January 1994, MWSG-47 oversaw further changes in locations of its subordinate commands. The Base Realignment and Closure Commission (BRAC) reports of 1991 and 1993 caused the movement of the MWSS headquarters detachments to the same geographic locations of the four Marine Aircraft Groups (MAGs) they supported. These changes were designed to make command and control relationships between the effected commands easier. During FY-2002, MWSG-47 was again reorganized. This included the deactivation of MWSS-474 and the re-flagging of other detachments. During this reorganization some squadron detachments were transferred to other major subordinate commands within Marine Forces Reserve and some were gained. At this time the designation for specific support to fixed or rotary wing squadrons was dropped. When the dust settled, MWSG-47 was left with Marines at nine sites across the United States. In 2010, the Marine Corps Force Structure Review Group submitted the recommendation that all MWSGs, active and reserve, be deactivated and their subordinate MWSSs reassigned to the MAGs they support. This recommendation led to MWSS-471 and MWSS-473 transferring to MAG-41 and MWSS-472 transferring to MAG-49 in 2012. When the MWSS transfers were complete, the deactivation of Marine Wing Support Group 47 occurred in July, 2012, concluding 50 years of service. ==Deployment History==
