Military budget of the United States
The military budget is the 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. This 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 equipment. The budget funds all branches of the U.S. military: the Army, Marine Corps, Navy, Air Force, and Coast Guard.
For the period 2010-14, SIPRI found that the United States was the world's biggest exporter of major arms, accounting for 31 percent of global shares, followed by Russia with 27 percent. The USA delivered weapons to at least 94 recipients. The United States was also the world's eighth largest importer of major military equipment for the same period. The main imports were 19 transport aircraft from Italy; and equipment produced in the US under licence–including 252 trainer aircraft of Swiss design, 223 light helicopters of German design and 10 maritime patrol aircraft of Spanish design.
