History

Proposals to coordinate the activities of the military services were initially considered by Congress in 1944. Specific plans were put forth in 1945 by the Army, the Navy, and the Joint Chiefs of Staff. In a special message to Congress on December 19, 1945, President Harry Truman proposed creation of a unified Department of National Defense. A proposal reached Congress in April 1946, but was held up by the Naval Affairs Committee held hearings in July 1946 due to objections to the concentration of power in a single department. Truman eventually sent new legislation to Congress in February 1947, where it was debated and amended for several months.

On July 26, 1947, Truman signed the National Security Act of 1947, which set up the National Military Establishment to begin operations on September 18, 1947, the day after the confirmation of James V. Forrestal as the first Secretary of Defense. The Establishment was later renamed the Department of Defense on August 10, 1949 and the secretary was given greater authority over the military departments of the Army, Navy, and Air Force.

It is based in The Pentagon in Arlington County, Virginia near Washington, DC. It was created by combining the War Department (founded in 1789) with the Navy Department (founded in 1798; formerly the Board of Admiralty, founded in 1780), and the newly created Department of the Air Force. The department was formed in order to reduce interservice rivalry which was believed to have reduced military effectiveness during World War II.

It includes Army, Air Force, Coast Guard (wartime only), Navy, Marines and agencies such as the National Security Agency and the Defense Intelligence Agency comprise the Department. Its annual budget is roughly $375 billion (~$1,300 per capita), which does not include billions more in supplemental expenditures alloted by Congress throughout the year.

The command structure of the Department of Defense is defined by the Goldwater-Nichols Act of 1986. Under the act, the chain of command runs from the President of the United States, through the Secretary of Defense, to the regional commanders within one of several commands who command all military forces within their area of operation. The Chairman of the Joint Chiefs of Staff and the several Chiefs of Staff are responsible for readiness of the U.S. military, but are not in the chain of command.

On February 22, 2002, the Department of Defense Office of the Inspector General has reported that DOD has not and will not account for $1.1 trillion of "undocumentable adjustments."

As part of the September 11, 2001 attacks, terrorists crashed a plane into one of the sections of The Pentagon, causing part of it to collapse, killing 189 people.

Operating units

In 2003, the National Communications System was moved to the United States Department of Homeland Security.

Technology

The DoD sponsored the research and development of the modern computer and through DARPA subsidized the creation of the Internet. It maintains the global positioning system (GPS). Each of these technologies was made available to the public worldwide at no charge.

The DoD commissioned the design of the Ada programming language.
