General Dynamics makes money four ways: it builds nuclear-powered submarines and Navy destroyers, manufactures Gulfstream business jets, produces tanks and munitions, and runs technology and IT services for the U.S. government. Each time it delivers a ship, an aircraft, a vehicle, or completes a service contract, it gets paid. The U.S. government accounts for 68% of total revenue, making it by far the dominant customer. The diagram below traces where the money flows through each of these four businesses.
Five years of financial data tell a clear story: this is a business growing steadily in both size and cash generation. Revenue has climbed from $38.5 billion in 2021 to $52.5 billion in 2025. Operating cash flow has risen from $4.3 billion to $5.1 billion over the same period. Net debt has fallen from $9.9 billion to $5.7 billion, meaning the company owes meaningfully less than it did four years ago. These three trends moving together, more revenue, more cash, less debt, suggest a business that is not just growing but also getting financially healthier.
One number captures the forward momentum better than any single year of results. The total backlog, meaning contracts already won but not yet delivered, reached $118 billion at the end of 2025. That is up 30% from $90.6 billion at the end of 2024. The defense segments alone held $96.2 billion of that backlog. For the Marine Systems division, which builds submarines, the total estimated contract value including options stretched to $64.2 billion. The Columbia-class ballistic-missile submarine program alone has a Navy program of record worth more than $125 billion, with construction scheduled to span two decades.
There is one financial wrinkle worth examining. Gross margin has been quietly slipping each year, from 16.7% in 2021 down to 15.1% in 2025. This is not a dramatic collapse, but the direction is consistent. The most likely explanation is that the Marine Systems segment, which builds submarines and destroyers at operating margins of around 7%, is growing faster than higher-margin segments like Aerospace at 13% and Combat Systems at 14%. As submarine construction volume ramps up to meet Navy demand, it pulls the overall average down. Free cash flow dipped to $3.2 billion in 2024 before recovering to $4.0 billion in 2025, a reminder that large capital spending programs can create short-term cash pressure even when the underlying business is healthy.
The Gulfstream business runs on a different logic from the defense side. It sells to wealthy individuals and corporations, not governments. Revenue from aircraft manufacturing jumped from $5.7 billion in 2023 to $9.4 billion in 2025, driven by the new G700 and the G800, which received FAA certification in April 2025 and entered service that same year. The Aerospace segment booked orders at a rate of 1.2 times revenue in 2025, meaning new orders came in faster than deliveries went out. That backlog for Aerospace stood at $21.8 billion at year end. But this segment is the one most exposed to the broader economy. If wealthy customers stop buying jets or the economy weakens sharply, Gulfstream revenues can fall.
The company raised its quarterly dividend for the 28th consecutive year in 2025, to $1.50 per share. That kind of streak requires reliable cash generation through all kinds of economic conditions. The consistency is notable, but it also means the company has made a long-standing financial promise that must be funded regardless of what happens to contract timing or defense budgets in any given year.
The risks here are specific and documented. The U.S. government supplies approximately 68% of total revenue, meaning a single customer's budget decisions drive the majority of the business. The government can cancel contracts at any time for its own convenience, paying only for work already completed. In 2025, the Technologies segment experienced contract modifications, terminations, and award delays tied to federal spending reviews and a government shutdown at the start of the fiscal year. For some critical materials, including semiconductors, the company relies on a single supplier, so any disruption in that supply chain can halt production. Tariffs reduced Aerospace operating margins by 30 basis points in 2025, and an Israel-based supplier of mid-cabin airframes was disrupted by regional conflict. These are not hypothetical concerns. They showed up in the most recent results.
The structure of this business means that most of the interesting questions are about what happens over the next ten to twenty years, not the next quarter. Submarine programs span decades. The Columbia-class program is scheduled to run through the 2040s. The Virginia-class has 14 boats in backlog with deliveries through 2034. That kind of visibility is unusual. But it also means that today's margins on new submarine contracts, which start lower and improve as learning curve efficiencies kick in, will take years to work their way fully into the financial results.
