About
Northrop Grumman Corporation is a Falls Church, Virginia-based global aerospace and defense technology company — publicly traded on the New York Stock Exchange (NYSE: NOC) as an S&P 500 Industrials component — designing, developing, producing, and maintaining advanced defense systems including stealth combat aircraft, space systems, ground-based strategic nuclear weapons, battle management systems, and unmanned systems through approximately 95,000 employees worldwide. In fiscal year 2024, Northrop Grumman reported revenue of approximately $41 billion, with defense spending tailwinds from NATO alliance expansion, Indo-Pacific military modernization, and US Air Force strategic deterrence modernization. Northrop Grumman secured $1.4 billion in contracts to advance the Integrated Battle Command System (IBCS) — a next-generation air and missile defense battle management system for the US Army and Poland, connecting disparate sensors (radar, sonar, space-based sensors) and effectors (Patriot batteries, short-range air defense missiles) through a unified software-defined kill chain. CEO Kathy Warden — the first female CEO of a major US defense contractor — leads Northrop's strategy of focusing on the highest-technology defense programs where integration complexity creates durable sole-source competitive positions. The B-21 Raider stealth strategic bomber (the first new US strategic bomber in 35 years, beginning operational deliveries in 2024) is Northrop's defining program — a next-generation nuclear-capable stealth aircraft intended to replace the B-2 Spirit and eventually the B-1 Lancer through the late 2030s.
