United States Department of Defense

The National Security Act of 1947 was a law enacting major restructuring of the United States government's military and intelligence agencies following World War II. The majority of the provisions of the act took effect on September 18, 1947, the day after the Senate confirmed James Forrestal as the first secretary of defense.

The Parliament of Great Britain was formed in May 1707 following the ratification of the Acts of Union by both the Parliament of England and the Parliament of Scotland. The Acts ratified the treaty of Union which created a new unified Kingdom of Great Britain and created the parliament of Great Britain located in the former home of the English parliament in the Palace of Westminster, near the City of London. This lasted nearly a century, until the Acts of Union 1800 merged the separate British and Irish Parliaments into a single Parliament of the United Kingdom with effect from 1 January 1801.

The First Continental Congress was a meeting of delegates from 12 of the 13 British colonies that became the United States. It met from September 5 to October 26, 1774, at Carpenters' Hall in Philadelphia, Pennsylvania, after the British Navy instituted a blockade of Boston Harbor and the Parliament of Great Britain passed the punitive Intolerable Acts in response to the December 1773 Boston Tea Party. During the opening weeks of the Congress, the delegates conducted a spirited discussion about how the colonies could collectively respond to the British government's coercive actions, and they worked to make a common cause.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was the military conflict of the American Revolution in which American Patriot forces under George Washington's command defeated the British, establishing and securing the independence of the United States. Fighting began on April 19, 1775, at the Battles of Lexington and Concord. The war was formalized and intensified following passage of the Lee Resolution on July 2, 1776, which asserted that the Thirteen Colonies were "free and independent states", and the Declaration of Independence, drafted by the Committee of Five and written primarily by Thomas Jefferson, two days later, on July 4, 1776, by the Second Continental Congress in Philadelphia.

The Second Continental Congress was a late-18th-century meeting of delegates from the Thirteen Colonies that united in support of the American Revolutionary War. The Congress created a new country that it first named the United Colonies, and in 1776, it renamed the United States of America. The Congress convened in Philadelphia, then the federal capital, on May 10, 1775, with representatives from 12 of the 13 colonies. This came shortly after the Battles of Lexington and Concord and was in succession to the First Continental Congress which met from September 5 to October 26, 1774. The Second Congress functioned as a de facto national government at the outset of the Revolutionary War by raising armies, directing strategy, appointing diplomats, and writing petitions such as the Declaration of the Causes and Necessity of Taking Up Arms and the Olive Branch Petition. All thirteen colonies were represented by the time the Congress adopted the Lee Resolution which declared independence from Britain on July 2, 1776, and the congress agreed to the Declaration of Independence two days later.

The Continental Army was the army of the United Colonies representing the Thirteen Colonies and later the United States during the American Revolutionary War. It was formed on June 14, 1775 by a resolution passed by the Second Continental Congress, meeting in Philadelphia after the war's outbreak. The Continental Army was created to coordinate military efforts of the colonies in the war against the British, who sought to maintain control over the American colonies. General George Washington was appointed commander-in-chief of the Continental Army and maintained this position throughout the war.

In the United States, Flag Day is celebrated on June 14. It commemorates the adoption of the flag of the United States on June 14, 1777, by resolution of the Second Continental Congress. The Flag Resolution, passed on June 14, 1777, stated: "Resolved, That the flag of the thirteen United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new constellation."

The Continental Navy was the navy of the Thirteen Colonies during the American Revolutionary War. Founded on October 13, 1775, the fleet developed into a relatively substantial force throughout the Revolutionary War, owing partially to the substantial efforts of the Continental Navy's patrons within the Continental Congress. These Congressional Patrons included the likes of John Adams, who served as the Chairman of the Naval Committee until 1776, when Commodore Esek Hopkins received instruction from the Continental Congress to assume command of the force.

The Continental Marines were the amphibious infantry of the American Colonies during the American Revolutionary War. The Corps was formed by the Continental Congress on November 10, 1775 and was disbanded in 1783. Their mission was multi-purpose, but their most important duty was to serve as onboard security forces, protecting the captain of a ship and his officers. During naval engagements, in addition to manning the cannons along with the crew of the ship, Marine sharpshooters were stationed in the fighting tops of a ship's masts specifically to shoot the opponent's officers, naval gunners, and helmsmen.

The 1st United States Congress, comprising the United States Senate and the United States House of Representatives, met from March 4, 1789, to March 4, 1791, during the first two years of George Washington's presidency, first at Federal Hall in New York City and later at Congress Hall in Philadelphia. With the initial meeting of the First Congress, the United States federal government officially began operations under the new frame of government established by the 1787 Constitution. The apportionment of seats in the House of Representatives was based on the provisions of Article I, Section 2, Clause 3, of the Constitution. Both chambers had a Pro-Administration majority. Twelve articles of amendment to the Constitution were passed by this Congress and sent to the states for ratification; the ten ratified as additions to the Constitution on December 15, 1791, are collectively known as the Bill of Rights, with an additional amendment ratified more than two centuries later to become the Twenty-seventh Amendment to the United States Constitution.

George Washington was an American military officer, statesman, and Founding Father who served as the first president of the United States from 1789 to 1797. Appointed by the Continental Congress as commander of the Continental Army, Washington led Patriot forces to victory in the American Revolutionary War and served as president of the Constitutional Convention of 1787, which created and ratified the Constitution of the United States and the American federal government. Washington has been called the "Father of his Country" for his manifold leadership in the nation's founding.

The Central Intelligence Agency, known informally as the Agency and historically as the company, is a civilian foreign intelligence service of the federal government of the United States, officially tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT) and conducting covert action. As a principal member of the United States Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet of the United States. Following the dissolution of the Office of Strategic Services (OSS) at the end of World War II, President Harry S. Truman created the Central Intelligence Group under the direction of a Director of Central Intelligence by presidential directive on January 22, 1946, and this group was transformed into the Central Intelligence Agency by implementation of the National Security Act of 1947.

The United States Department of Defense (DoD) has a complex organizational structure. It includes the Army, Navy, the Marine Corps, Air Force, Space Force, the Unified combatant commands, U.S. elements of multinational commands, as well as non-combat agencies such as the Defense Intelligence Agency and the National Security Agency. The DoD's annual budget was roughly US$496.1 billion in 2015. This figure is the base amount and does not include the $64.3 billion spent on "War/Non-War Supplementals". Including those items brings the total to $560.6 billion for 2015.

The Constitution of the United States is the supreme law of the United States of America. It superseded the Articles of Confederation, the nation's first constitution, in 1789. Originally comprising seven articles, it delineates the national frame and constraints of government. The Constitution's first three articles embody the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral Congress ; the executive, consisting of the president and subordinate officers ; and the judicial, consisting of the Supreme Court and other federal courts. Article IV, Article V, and Article VI embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment. Article VII establishes the procedure subsequently used by the 13 states to ratify it. The Constitution of the United States is the oldest and longest-standing written and codified national constitution in force in the world today.

The United States Congress is the legislature of the federal government of the United States. It is bicameral, composed of a lower body, the House of Representatives, and an upper body, the Senate. It meets in the U.S. Capitol in Washington, D.C. Senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a governor's appointment. Congress has 535 voting members: 100 senators and 435 representatives. The U.S. vice president has a vote in the Senate only when senators are evenly divided. The House of Representatives has six non-voting members.

The Office of the Secretary of Defense (OSD) is a headquarters-level staff of the United States Department of Defense. It is the principal civilian staff element of the U.S. Secretary of Defense, and it assists the Secretary in carrying out authority, direction and control of the Department of Defense in the exercise of policy development, planning, resource management, fiscal, and program evaluation responsibilities. OSD is the Secretary of Defense's support staff for managing the Department of Defense, and it corresponds to what the Executive Office of the President of the U.S. is to the U.S. president for managing the whole of the Executive branch of the federal government.

The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, that advises the president of the United States, the secretary of defense, the Homeland Security Council and the National Security Council on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of a chairman (CJCS), a vice chairman (VJCS), the chiefs of the Army, Marine Corps, Navy, Air Force, Space Force, and the chief of the National Guard Bureau. Each of the individual service chiefs, outside their JCS obligations, works directly under the secretaries of their respective military departments, e.g. the secretary of the Army, the secretary of the Navy, and the secretary of the Air Force.

The United States Department of the Army (DA) is one of the three military departments within the Department of Defense of the U.S. The Department of the Army is the federal government agency within which the United States Army (U.S.) is organized, and it is led by the secretary of the Army, who has statutory authority under 10 United States Code § 7013 to conduct its affairs and to prescribe regulations for its government, subject to the limits of the law, and the directions of the secretary of defense and the president.

The United States Department of the Navy (DON) is one of the three military departments within the Department of Defense of the United States of America. It was established by an Act of Congress on 30 April 1798, at the urging of Secretary of War James McHenry, to provide a government organizational structure to the United States Navy (USN); since 1834, it has exercised jurisdiction over the U.S. Marine Corps (USMC) and, during wartime, the U.S. Coast Guard (USCG), though each remains an independent service branch. It is led by the Secretary of the Navy (SECNAV), a statutory civilian officer.

The United States Department of the Air Force (DAF) is one of the three military departments within the Department of Defense of the United States of America. The Department of the Air Force was formed on September 18, 1947, per the National Security Act of 1947 and it is the military department within which the United States Air Force and the United States Space Force are organized.

The National Guard Bureau is the federal instrument responsible for the administration of the National Guard established by the United States Congress as a joint bureau of the Department of the Army and the Department of the Air Force. It was created by the Militia Act of 1903. The National Defense Authorization Act for Fiscal Year 2008, elevated the National Guard to a joint function of the Department of Defense. The 2007 NDAA, from the previous year, elevated the chief of the National Guard Bureau from a lieutenant general to a four-star general.

After leaving the CIA, Gates became president of Texas A&M University and was a member of several corporate boards. Gates served as a member of the Iraq Study Group, the bipartisan commission co-chaired by James A. Baker III and Lee H. Hamilton, that studied the lessons of the Iraq War.

The military budget is the largest portion of the discretionary United States federal budget allocated to the Department of Defense, or more broadly, the portion of the budget that goes to any military-related expenditures. The military budget pays the salaries, training, and health care of uniformed and civilian personnel, maintains arms, equipment and facilities, funds operations, and develops and buys new items. The budget funds five branches of the U.S. military: the Army, Navy, Marine Corps, Air Force, and Space Force.

This is a list of countries by military expenditure in a given year. Military expenditure figures are presented in United States dollars based on either constant or current exchange rates.

In American public finance, discretionary spending is government spending implemented through an appropriations bill. This spending is an optional part of fiscal policy, in contrast to social programs for which funding is mandatory and determined by the number of eligible recipients. Some examples of areas funded by discretionary spending are national defense, foreign aid, education and transportation.

The United States Federal Budget for Fiscal Year 2010, titled A New Era of Responsibility: Renewing America's Promise, is a spending request by President Barack Obama to fund government operations for October 2009–September 2010. Figures shown in the spending request do not reflect the actual appropriations for Fiscal Year 2010, which must be authorized by Congress.

A fiscal year is used in government accounting, which varies between countries, and for budget purposes. It is also used for financial reporting by businesses and other organizations. Laws in many jurisdictions require company financial reports to be prepared and published on an annual basis but generally not the reporting period to align with the calendar year. Taxation laws generally require accounting records to be maintained and taxes calculated on an annual basis, which usually corresponds to the fiscal year used for government purposes. The calculation of tax on an annual basis is especially relevant for direct taxes, such as income tax. Many annual government fees—such as council tax and license fees, are also levied on a fiscal year basis, but others are charged on an anniversary basis.

The United States Congress is the legislature of the federal government of the United States. It is bicameral, composed of a lower body, the House of Representatives, and an upper body, the Senate.

The bill merged the responsibilities of the Committee on Naval Affairs and the Committee on Military Affairs.

The United States Department of Defense is one of the largest single consumers of energy in the world, responsible for 93% of all US government fuel consumption in 2007 (Air Force: 52%; Navy: 33%; Army: 7%. Other DoD: 1%). In FY 2006, the DoD used almost 30,000 gigawatt hours (GWH) of electricity, at a cost of almost $2.2 billion. The DoD's electricity use would supply enough electricity to power more than 2.3 million average American homes. In electricity consumption, if it were a country, the DoD would rank 58th in the world, using slightly less than Denmark and slightly more than Syria (CIA World Factbook, 2006). The Department of Defense uses 4,600,000,000 US gallons (1.7×1010 L) of fuel annually, an average of 12,600,000 US gallons (48,000,000 L) of fuel per day. A large Army division may use about 6,000 US gallons (23,000 L) per day. According to the 2005 CIA World Factbook, if it were a country, the DoD would rank 34th in the world in average daily oil use, coming in just behind Iraq and just ahead of Sweden.
