Direct Answer
RTX Corporation reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Pratt and Whitney is the largest, with $32.9 billion of revenue (37% of the total), followed by Collins Aerospace at $30.2 billion (34%). 53% of revenue came from the United States.
How Does RTX Corporation Make Money?
No single line supplies a majority of revenue: the largest, Pratt and Whitney, is 37%, which spreads RTX Corporation's exposure across several demand drivers. Between fiscal 2024 and 2025, Pratt and Whitney grew fastest (+17.3%) and Raytheon slowest (+5.0%), so the revenue mix tilts toward Pratt and Whitney while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Pratt and Whitney | $32.9 billion | $28.1 billion | 37.1% | 17.3% |
| Collins Aerospace | $30.2 billion | $25.9 billion | 34.1% | 16.5% |
| Raytheon | $28.0 billion | $26.7 billion | 31.7% | 5.0% |
Which RTX Corporation Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Pratt and Whitney | $2.6 billion | 7.9% |
| Collins Aerospace | $4.9 billion | 16.3% |
| Raytheon | $3.2 billion | 11.5% |
Segment operating income is the profit measure RTX Corporation 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 RTX Corporation more safely than against another company.
What Does RTX Corporation Sell?
RTX Corporation 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 | $64.2 billion | $59.6 billion | 72.4% | 7.6% |
| Service | $24.4 billion | $21.1 billion | 27.6% | 15.6% |
Where Does RTX Corporation's Revenue Come From?

| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| United States | $47.3 billion | $46.1 billion | 53.4% | 2.6% |
| Europe | $18.8 billion | $16.0 billion | 21.2% | 17.7% |

What the Segment Figures Do Not Show
The rows above add up to 103% of RTX Corporation'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 RTX Corporation reported in the segment note and revenue disclosures of its Form 10-K filed February 6, 2026 (accession 0000101829-26-000006), 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.
