The 621st Contingency Response Wing (621 CRW) is a United States Air Force rapid response expeditionary wing, based out of Joint Base McGuire-Dix-Lakehurst, New Jersey and Travis Air Force Base, California highly-specialized in training and rapidly deploying personnel globally to quickly open airfields and establish, expand, sustain, and coordinate air mobility operations during a variety of contingency operations. The 621st consists of approximately 1500 airmen in six groups, fourteen squadrons and more than 20 geographically separated operating locations aligned with major Army and Marine Corps combat units. Four Contingency Response Groups (817th, 818th, 570th and 571st CRGs) provide the core cadre of expeditionary command and control, airlift and air refueling operations and aircraft maintenance personnel for deployment worldwide as mobility control teams and airfield assessment teams. These teams rapidly survey, assess and establish contingency air bases and expand existing Air Mobility Command support infrastructure worldwide. Mission The 621st CRW is highly specialized in training and rapidly deploying personnel to quickly open airfields and establish, expand, sustain, and coordinate air mobility operations. From wartime taskings to disaster relief, the 621st extends Air Mobility Command's (AMC) reach in deploying people and equipment around the globe. Most of the operations can be classified by three types: Joint Task Force - Port Opening (JTF-PO), where USAF and US Army units create distribution chains; Expeditionary Air Mobility Support, (EAMS) where CRW personnel augment existing forces for the mission; and Initial Airbase Opening (IAO). Other operations include: Air Advisory with partner nations, augmenting or stand alone Command and Control (C2), and Air Advisory of airlift assets for U.S. Army and Marine Units. History The 621st was established on 24 June 1994 as the 621st Air Mobility Operations Group before being activated on 22 July of that year at McGuire Air Force Base (part of Joint Base McGuire–Dix–Lakehurst since 2009). It was expanded into the 621st Contingency Response Wing on 1 March 2005. The 621st included four groups, eight squadrons and ten geographically separated operating locations aligned with major US Army and Marine Corps combat units. The wing maintains a ready corps of light, lean and agile mobility support forces able to respond as directed by the 18th Air Force at Scott Air Force Base, Ill., in order to meet Combatant Command wartime and humanitarian requirements. Following the 2010 Haiti earthquake of 12 January, the 817th Contingency Response Group deployed to Toussaint L'Ouverture International Airport, Port-au-Prince, Haiti
