Direct Answer
Lockheed Martin reports revenue across 4 business segments in its fiscal 2025 Form 10-K. Aeronautics is the largest, with $30.3 billion of revenue (40% of the total), followed by Rotary and Mission Systems at $17.3 billion (23%). 72% of revenue came from the United States.
How Does Lockheed Martin Make Money?
No single line supplies a majority of revenue: the largest, Aeronautics, is 40%, which spreads Lockheed Martin's exposure across several demand drivers. Between fiscal 2024 and 2025, Missiles and Fire Control grew fastest (+13.9%) and Rotary and Mission Systems slowest (+0.3%), so the revenue mix tilts toward Missiles and Fire Control while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Aeronautics | $30.3 billion | $28.6 billion | 40.3% | 5.7% |
| Rotary and Mission Systems | $17.3 billion | $17.3 billion | 23.1% | 0.3% |
| Missiles and Fire Control | $14.4 billion | $12.7 billion | 19.3% | 13.9% |
| Space | $13.0 billion | $12.5 billion | 17.4% | 4.4% |
Which Lockheed Martin Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Aeronautics | $2.1 billion | 6.9% |
| Rotary and Mission Systems | $1.3 billion | 7.6% |
| Missiles and Fire Control | $2.0 billion | 13.8% |
| Space | $1.3 billion | 10.3% |
Segment operating income is the profit measure Lockheed Martin 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 Lockheed Martin more safely than against another company.
What Does Lockheed Martin Sell?
Lockheed Martin 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 | $62.7 billion | $59.3 billion | 83.5% | 5.7% |
| Service | $12.4 billion | $11.8 billion | 16.5% | 5.3% |
Where Does Lockheed Martin's Revenue Come From?
Regions follow the definitions in the filing; most companies assign revenue by customer location.
| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| United States | $53.7 billion | $52.5 billion | 71.6% | 2.2% |
| Europe | $8.8 billion | $7.7 billion | 11.7% | 14.1% |

What the Segment Figures Do Not Show
The rows above add up to 100% of Lockheed Martin'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 Lockheed Martin reported in the segment note and revenue disclosures of its Form 10-K filed January 29, 2026 (accession 0001628280-26-004195), 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.
