How Northrop Grumman Makes Money

Northrop Grumman is a government contractor: the large majority of its sales come from the U.S. government, with the rest from allied governments (often through Foreign Military Sales) and a small commercial space business. It works across four segments. Aeronautics Systems builds the B-21 Raider, F-35 center fuselages, the E-2D Hawkeye and uncrewed aircraft such as Global Hawk and Triton. Defense Systems makes tactical weapons, ammunition, rocket motors for missiles and sustainment services. Mission Systems supplies radars (including the F-35's APG-81), electronic warfare, communications, the Army's IBCS air-defense command system and microelectronics. Space Systems builds satellites and payloads, the Sentinel ICBM, solid rocket boosters for NASA's SLS and the Cygnus cargo spacecraft. Revenue comes through a mix of cost-reimbursable development contracts and fixed-price production contracts; fixed-price work earns more when executed well but exposes the company to losses when costs run over, as happened on early B-21 production lots.

Northrop is concentrating investment where it already holds franchise positions: B-21 production capacity (more than $5 billion invested in digital engineering and manufacturing), the Sentinel ICBM, solid rocket motors and munitions, missile-defense systems such as IBCS and the Glide Phase Interceptor, and classified and missile-tracking space constellations. International sales of IBCS, E-2D, Triton and munitions to allies are another growth lever.
