what does the united states produce the most of
Manufacturing in the United States The largest manufacturing industries in the United States by revenue include petroleum, steel, automobiles, aerospace, telecommunications, chemicals, electronics, food processing, consumer goods, lumber, and mining. A large portion of U.S. industrial output, the United States leads the world in airplane manufacturing. American companies such as Boeing, Cessna (see: Textron), Lockheed Martin (see: Skunk Works), and General Dynamics produce a vast majority of the world's civilian and military aircraft in factories stretching across the United States.
Automotive industry in the United States The automotive industry in the United States began in the 1890s and, as a result of the size of the domestic market and the use of mass-production, rapidly evolved into the largest in the world. However, the United States was overtaken as the largest automobile producer by Japan in the 1980s, and subsequently by China in 2008. The U.S. is currently second among the largest manufacturer in the world by volume, with approximately 8-10 million manufactured annually. Notable exceptions were 5.7 million automobiles manufactured in 2009 (due to crisis), and peak production levels of 13-15 million units during the 1970s and early 2000s.[1][2][3]
