The United States Air Force Memorial honors the service and sacrifices of the men and women of the United States Air Force. The spire structure consists of stainless steel plates with high-strength concrete filling the lower 2/3 of each spire. The upper third is hollow stainless steel.[6] At the transition between concrete and hollow steel portions, dampers provide aerodynamic stability and dissipate wind sway energy. Each damper consists of a lead ball weighing about a ton that is allowed to roll inside a steel box. The structural design of the spires was completed by the Arup engineering consultancy. Designed by American architect James Ingo Freed (known for the design of the United States Holocaust Memorial Museum) with the firm Pei Cobb Freed & Partners for the United States Air Force Memorial Foundation. Unveiled 14th October, 2006.
