From 24/7 Wall St.: The business of war is profitable. In 2011, the 100 largest contractors sold $410 billion in arms and military services. Just 10 of those companies sold over $208 billion. Based on a list of the top 100 arms-producing and military services companies in 2011 compiled by the Stockholm International Peace Research Institute, 24/7 Wall St. reviewed the 10 companies with the most military sales worldwide in 2011.
These companies have benefited tremendously from the growth in military spending in the U.S., which by far has the largest military budget in the world. In 2000, the U.S. defense budget was approximately $312 billion. By 2011, that figure had grown to $712 billion. Arm sales grew alongside general defense spending growth. SIPRI noted that between 2002 and 2011, arms sales among the top 100 companies grew by 51%.
