General Dynamics Corp

General Dynamics sells defense systems and business jets. It has four main businesses: building Gulfstream private jets and servicing aircraft; making armored military vehicles (M1 Abrams tanks, Stryker carriers) and munitions; constructing and maintaining nuclear submarines, destroyers, and naval ships; and providing IT services and military electronics (communications, surveillance, reconnaissance systems) primarily to government customers. Revenue comes from long-term government defense contracts and direct jet sales, with the U.S. military as its dominant customer.
