Joint Base Elmendorf–Richardson (JBER) is a United States military facility located in Anchorage, Alaska. It was formed in 2010 through the merger of the United States Air Force's Elmendorf Air Force Base and the United States Army's Fort Richardson, following the 2005 Base Closure and Realignment Commission. The base was originally built in 1940 as Elmendorf Field and Fort Richardson. JBER is owned by the Department of Defense and operated by the US Air Force, under the control of Pacific Air Forces (PACAF). Its mission involves supporting U.S. interests in the Asia Pacific region by providing units ready for worldwide air power projection and a base capable of meeting USINDOPACOM's theater staging and throughput requirements. The host unit is the 673rd Air Base Wing, which manages the joint base operations. Other major units stationed at JBER include the Headquarters, Alaskan Command (ALCOM), Alaskan NORAD Region (ANR), Joint Task Force-Alaska (JTF-AK), Eleventh Air Force (11 AF), the 3rd Wing, and the 176th Wing. The 176th Wing, part of the Alaska Air National Guard, relocated to JBER in 2011 from the former Kulis Air National Guard Base. The base features two asphalt runways: 06/24, measuring 3,048 meters (10,000 feet), and 16/34, measuring 2,283.8 meters (7,493 feet). JBER has been the site of aviation accidents, including a C-17 Globemaster III crash in 2010 and an F-22 Raptor crash in 2010.
