Northrop Grumman Corporation (NOC) Business Profile

What it does

Northrop Grumman Corporation is an aerospace and defense technology company founded in 1994 and headquartered in Falls Church. Kathy J. Warden is Chair, Chief Executive Officer and President. It designs, develops, builds, integrates, sustains and modernizes systems for the U.S. government, the intelligence community, international customers and some civil and commercial space customers.

Its four operating sectors cover different parts of national-security missions. Aeronautics Systems makes military aircraft and related sustainment, including long-range strike, fighter-aircraft structures, airborne command-and-control systems, and uncrewed surveillance aircraft. Defense Systems provides strategic missiles, missile defense, tactical weapons, ammunition, solid rocket motors, propulsion, command-and-control systems and weapons sustainment.

Mission Systems supplies the electronics and equipment that detect, communicate, navigate, process information and protect platforms: radars, infrared and acoustic sensors, electronic warfare, C4ISR systems, microelectronics, cyber capabilities, submarine propulsion equipment and aircraft countermeasures. Space Systems builds and operates spacecraft, satellites, payloads, ground systems, missile-defense systems, interceptors, launch vehicles and propulsion systems.

Some programs are restricted, meaning the U.S. government prohibits public discussion of their details. Restricted work accounts for approximately 40 percent of Aeronautics Systems, 30 percent of Mission Systems and 45 percent of Space Systems. The company had approximately 95,000 employees at December 31, 2025.

How it makes money

Northrop Grumman earns revenue primarily by performing long-term government contracts for development, production and support. It may be the prime contractor dealing directly with the customer, or a subcontractor to another contractor. Its four reportable segments are Aeronautics Systems, Defense Systems, Mission Systems and Space Systems.

Aeronautics Systems earns revenue from aircraft development, production, modernization and sustainment, including the B-21, B-2, E-130J, F-35 fuselages, E-2D, Triton and Global Hawk. Defense Systems earns from strategic deterrence, missile defense, weapons, ammunition, propulsion and command-and-control programs, including Sentinel, IBCS, GMLRS subsystems, AARGM, SiAW and solid rocket motors. Mission Systems sells sensors, radar, avionics, electronic warfare, cyber, aircraft-protection systems and naval propulsion equipment. Space Systems sells satellites, spacecraft, launch propulsion, ground systems and missile-defense products.

Cost-type contracts generally reimburse allowable costs plus a fee. They expose the company to less unanticipated-cost risk but generally provide lower margins. Fixed-price contracts set a negotiated price for a defined scope; they can provide higher margins, but the company bears more of the cost-growth risk.

Revenue can recur through follow-on production, spare parts, sustainment, modernization and operations support after an initial development award. For the year ended December 31, 2025, the company reported total sales; third-quarter 2026 sales were $11.1 billion.

Customers and how it sells

The U.S. government is Northrop Grumman’s largest customer and accounted for 84 percent of 2025 sales. The company principally serves the Department of War and the intelligence community, while also selling to other U.S. government agencies, international governments, civil-government customers and commercial customers in selected space activities. Its international sales include foreign military sales contracted through the U.S. government.

Each operating segment derives a substantial percentage of revenue from the U.S. government. Customer access is principally through direct government contracts and through subcontracts where another company is the prime contractor. On major defense programs, companies may share work; Northrop Grumman can compete against a peer for a prime award while supplying that peer on another program.

Its stated international markets include U.S. allies and partner nations. Examples of users named across its portfolio include Japan, France, Australia, Poland, NATO, the Republic of Korea and the U.S. Navy, Air Force and Army. The company expects international sales to be a growth driver and has a goal to double international sales by 2031.

Suppliers and costs

Northrop Grumman’s cost base includes labor, engineering, materials, components, subcontractors, manufacturing capacity and program-development spending. It had approximately 95,000 employees at December 31, 2025 and recruits for security clearances and skills in science, technology, engineering and math. About 4,300 employees were covered by 15 U.S. collective agreements.

The company uses suppliers and subcontractors extensively. At December 31, 2025, purchase obligations were $23.9 billion, largely open purchase orders to suppliers and subcontractors under U.S. government contracts. It has faced higher costs and longer lead times for some raw materials amid inflation, geopolitical conflicts and microelectronics shortages, although these conditions had not materially affected contract performance to that date.

Fixed-price work leaves the company more exposed if labor, material, supplier, design, production or schedule costs exceed estimates. The company is expanding facilities and capacity for B-21 production, solid rocket motors, hypersonic propulsion, space systems and aircraft work.

Competitive position

Northrop Grumman competes in defense, intelligence and federal civil markets with The Boeing Company, General Dynamics Corporation, L3Harris Technologies, Inc., Lockheed Martin Corporation and RTX Corporation, as well as newer entrants and startups. Competition occurs for government program awards across aircraft, weapons, missile defense, sensors, communications, space and intelligence systems. Competitors may also be customers or suppliers on separate programs.

The market has long operating cycles, competitive bid processes and protests of government procurement awards. New entrants can use commercial products, other transaction authority agreements and other procurement methods that can make it easier for them to pursue some opportunities. The company also faces pressure to be price- and cost-competitive and to respond to customer preferences for speed, affordability and different contracting structures.

Our reading: Long-running government programs, specialized engineering and manufacturing work, and restricted-program participation create meaningful barriers to entry, but these are not exclusive because multiple established contractors bid for the same work. [item1]

Our reading: Its installed base of sustainment, modernization and production programs supports continued work after development, although awards, options and production quantities remain controlled by customers. [item1]

Our reading: Technology protections provide a limited moat in government contracting because the U.S. government typically holds licenses to patents developed under its contracts and can authorize use for certain purposes. [item1]

Growth opportunities

Northrop Grumman’s growth plans center on production and development programs in strategic deterrence, military aircraft, national-security space, missile and munitions capacity, naval systems, autonomous aircraft, counter-uncrewed-aircraft systems, microelectronics and international sales. In the third quarter of 2026, bookings exceeded $16 billion and backlog reached $110 billion. Management expects full-year 2026 sales of $43.75 billion to $44.25 billion.

The company expects Sentinel to be a growth driver through the 2030s as development moves toward production. It is also investing to increase B-21 capacity, with higher production volumes expected later in the decade. Management expects B-21 acceleration capacity investments to continue through 2028. The company has 10 multiyear missile-acceleration agreements representing up to $10.0 billion of sales opportunity over the next seven years.

In space, the company launched and deployed its first 21 Tranche 1 transport-layer satellites and expects nearly 50 of its 150 satellites to be deployed over the following six months for transport and tracking missions. It is also evaluating strategic alternatives for its microelectronics capability while seeking defense and commercial applications for Fortitude and quantum technology.

The company expects 2027 sales growth of 5% to 7%, with growth in all four segments, and expects international sales to help drive growth. It has set a goal to double international sales by 2031.

Structural risks

• U.S. government concentration and funding: The U.S. government provided 84 percent of 2025 sales and can delay, modify, cancel or stop work on programs. Annual appropriations, continuing resolutions, shutdowns, debt-limit issues and changing priorities can delay funding, awards and payments.

• Contract execution and estimates: Large, complex contracts require estimates of revenue, cost and future performance. Cost growth, schedule delays, technical issues, supplier performance, labor and material availability, or unrecovered claims can reduce profitability.

• Fixed-price exposure: Approximately half of 2025 sales came from fixed-price contracts. These contracts shift more of the risk of inflation, labor shortages, supplier disruption, development uncertainty and production learning curves to the company.

• B-21 and Sentinel execution: B-21 low-rate initial production retains risk from remaining production learning-curve work. Sentinel continues through development, infrastructure and command-and-control work before an integrated test campaign and later production ramp.

• Competition and procurement change: Established peers, commercial contractors, startups and alternative acquisition approaches can reduce opportunities, increase pricing pressure and require the company to accept less favorable terms.

• Supply chain, workforce and regulation: Inflation, raw-material shortages, microelectronics constraints, tariffs, labor availability, cybersecurity and government-contract compliance requirements can increase costs, disrupt performance or lead to payment withholds and other sanctions.
