# L3Harris: Business Model & Revenue Engine

## Direct Answer

L3Harris reports revenue across 4 business segments in its fiscal 2025 Form 10-K. Space and Airborne Systems is the largest, with $6.9 billion of revenue (31% of the total), followed by Integrated Mission Systems at $6.6 billion (30%).

## How Does L3Harris Make Money?

No single line supplies a majority of revenue: the largest, Space and Airborne Systems, is 31%, which spreads L3Harris's exposure across several demand drivers. Between fiscal 2024 and 2025, Aerojet Rocketdyne grew fastest (+10.3%) and Integrated Mission Systems slowest (+0.2%), so the revenue mix tilts toward Aerojet Rocketdyne while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Space and Airborne Systems | $6.9 billion | $6.9 billion | 31.4% | 1.1% |
| Integrated Mission Systems | $6.6 billion | $6.6 billion | 30.0% | 0.2% |
| Communication Systems | $5.7 billion | $5.5 billion | 25.7% | 3.9% |
| Aerojet Rocketdyne | $2.8 billion | $2.6 billion | 12.9% | 10.3% |

## What Does L3Harris Sell?

L3Harris 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 | $15.5 billion | $15.1 billion | 70.8% | 2.3% |
| Service | $6.4 billion | $6.2 billion | 29.2% | 3.0% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of L3Harris'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 L3Harris reported in the segment note and revenue disclosures of its Form 10-K filed February 12, 2026 (accession 0000202058-26-000015), 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.
