Northrop Grumman is a defense contractor building military aircraft, space systems and missile defense technology, including the B-21 Raider stealth bomber program and a significant share of the country's satellite and space launch infrastructure. Its business depends heavily on long-term government contracts and defense budget appropriations, giving it long revenue visibility on major programs but also exposure to the political process that determines how much the government spends on defense each year. Northrop's space division has grown into a major part of the business, building satellites and spacecraft components for both government and commercial customers as space has become a more contested and commercially significant domain. Major defense programs like the B-21 bomber often span decades from initial development through full production, giving contractors like Northrop unusually long-duration revenue streams once a program is secured.
