Direct Answer
General Dynamics reports revenue across 4 business segments in its fiscal 2025 Form 10-K. Marine Systems is the largest, with $16.7 billion of revenue (32% of the total), followed by Technologies at $13.5 billion (26%).
How Does General Dynamics Make Money?
No single line supplies a majority of revenue: the largest, Marine Systems, is 32%, which spreads General Dynamics's exposure across several demand drivers. Between fiscal 2024 and 2025, Marine Systems grew fastest (+16.6%) and Technologies slowest (+2.6%), so the revenue mix tilts toward Marine Systems while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Marine Systems | $16.7 billion | $14.3 billion | 31.8% | 16.6% |
| Technologies | $13.5 billion | $13.1 billion | 25.6% | 2.6% |
| Aerospace | $13.1 billion | $11.2 billion | 24.9% | 16.5% |
| Combat Systems | $9.2 billion | $9.0 billion | 17.6% | 2.8% |
Which General Dynamics Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Marine Systems | $1.2 billion | 7.0% |
| Technologies | $1.3 billion | 9.5% |
| Aerospace | $1.7 billion | 13.3% |
| Combat Systems | $1.3 billion | 14.4% |
Segment operating income is the profit measure General Dynamics reports to its chief operating decision maker for each segment. It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within General Dynamics more safely than against another company.
What Does General Dynamics Sell?
General Dynamics also breaks revenue down by product and service line, which shows what customers pay for rather than how management organizes the business.
| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Product | $33.0 billion | $28.6 billion | 62.8% | 15.3% |
| Service | $19.5 billion | $19.1 billion | 37.2% | 2.3% |
What the Segment Figures Do Not Show
The rows above add up to 100% of General Dynamics's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value General Dynamics reported in the segment note and revenue disclosures of its Form 10-K filed January 30, 2026 (accession 0000040533-26-000006), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
