The 721st Air Mobility Operations Group (721 AMOG) is a United States Air Force (USAF) unit assigned to the 521st Air Mobility Operations Wing, stationed at Ramstein Air Base, Germany. History The squadron was reactivated in 1977 to operate the Military Airlift Command (MAC) aerial port at Ramstein Air Base. It serviced transient C-5 Galaxy and C-17 Globemaster transports at Ramstein, loading and unloading cargo and also received airlifted equipment and personnel for United States Army Europe (USAREUR) forces units in Germany. In August 1983, the squadron expanded to group size and was assigned separate aerial port and maintenance squadrons to carry out its mission. It was also assigned its first flying squadron, the 58th Military Airlift Squadron (MAS), which was assigned from the 322d Airlift Division. The assumption of the airlift mission was reflected when the group was redesignated the 608th Military Airlift Group. The 10th MAS at Zweibrücken Air Base which operated C-23 Sherpa transports in support of USAFE's European Distribution System (EDS) was also reassigned from the 322d Airlift Division in 1984. The EDS was organized to give units in Europe a quicker way to receive small equipment items or supplies on a round-the-clock basis, without the expense of the larger cargo aircraft. The group also supported Special Air Transportation of HQ USAFE executives with a fleet of light transport. The 10th MAS was inactivated in 1991. in 1992, USAF embarked on a major reorganization of its Major Commands. In this reorganization, theater airlift was reassigned from the inactivating MAC. The host 86th Fighter Wing at Ramstein became the 86th Wing and the 58th MAS was redesignated the 58th Airlift Squadron and assigned to the wing's 86th Operations Group. The 608th's mission became strategic airlift support once again as it was redesignated the 608th Airlift Support Group of Air Mobility Command (AMC). However, its mission expanded to include support for all of Europe and it was assigned squadrons at Torrejon AB, Spain, and RAF Mildenhall, England. In recognition of its responsibility to support not only airlift, but the air refueling mission of AMC, it became the 621st Air Mobility Support Group in 1994 and was renumbered the because USAF policy required subordinate support units numbers to reflect their parent organization's number and the group was assigned to Twenty-First Air Force. It became the 721st Air Mobility Operations Group in 2001. The group's Detachment 5 was located at
