The United States Air Force Memorial honors the service of the personnel of the United States Air Force and its heritage organizations. The Memorial is located in Arlington County, Virginia, on the former grounds of the Navy Annex near The Pentagon and Arlington National Cemetery. The Memorial is southwest of the intersection of Columbia Pike and South Joyce Street and is accessible from the north side of Columbia Pike. It was the last project of American architect James Ingo Freed with the firm Pei Cobb Freed & Partners.

The Navy Annex was a building near the Pentagon in Arlington, Virginia mainly used as offices for the United States Department of the Navy. The facility was also known as Federal Office Building 2. It was demolished in 2013 to make room for an expansion of Arlington National Cemetery and other uses.
