The national security strategy of engagement and enlargement calls for the US to be engaged around the world with the objective of enlarging the family of democratic nations. This strategy depends on maintaining strong defense and ensuring that America's military forces are ready to deter, fight and win wars. At the same time the Air Force is reducing the number of forward deployed forces, and putting increased emphasis on expeditionary, mobile forces that can deploy quickly. Air power is well-suited to meet these requirements and offers the national a broad range of capabilities to support its security strategy. The Chairman of the Joint Chiefs of Staff recently published Joint Vision 2010, his vision for joint war fighting in the future. The Air Force is already developing many of the systems required to support Joint Vision 2010. This vision will support the national strategy and the Joint vision by recognizing the reality that in the first quarter of the 21st century, it will become possible to find, fix, or track, and target anything that moves on the surface of the earth.
