Defense Industry Statistics: Backlog, Revenue, and Cash Flow

Defense industry statistics at a glance

The defense industry is shaped by scale, backlog, and the ability to turn multi-year demand into dependable cash flow. The latest figures in this dataset show how large the sector’s leading contractors have become, and how much of their value is tied to funded orders, free cash generation, and long-term program pipelines.

What the defense industry statistics show

The most useful way to read defense industry statistics is not as a single market total, but as a pattern across prime contractors. The numbers in this dataset point to five consistent themes: large revenue bases, very large backlogs, strong cash conversion at several firms, substantial shareholder returns, and workforces that combine scale with deep technical specialization.

Key takeaway: the sector is not just about annual sales. It is also about whether companies can preserve backlog, convert funded programs into cash, and sustain engineering capacity over time.

That is why this dataset emphasizes both operating results and backlog. A company with strong revenue but weak backlog would look very different from one with lower current sales but an exceptionally deep pipeline of funded work. The leading names here all show some combination of both.

Why the numbers matter

• Revenue and sales show current demand.
• Backlog shows how much work is already booked for future periods.
• Cash from operations and free cash flow show how efficiently programs are turning into cash.
• Employee counts show how much of the sector depends on specialized labor, not just capital.

Those dimensions matter because defense programs are long-cycle. A one-year sales figure is only part of the story. The backlog figures in this dataset reveal how much future activity is already committed.

Revenue, sales, and orders by major contractor

The biggest contractors in the dataset operate at very different scales, but they all sit in the same general range of very large annual revenue. The spread is useful because it shows how concentrated the industry is among a small number of global primes.

What stands out in the comparison

• RTX had the largest reported revenue in this dataset at $80.8 billion and the largest backlog at $218 billion (RTX Reports 2024 Results and Announces 2025 Outlook; RTX 2024 Annual Report).
• Lockheed Martin combined $71.0 billion of net sales with a $176.0 billion record backlog, which is one of the strongest revenue-to-backlog profiles in the group (Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results).
• Northrop Grumman and General Dynamics each sat in the low-to-mid-$40 billions on revenue while still holding backlogs around $90 billion (Northrop Grumman 2024 Annual Report; General Dynamics Reports Fourth-Quarter and Full-Year 2024 Financial Results).
• BAE Systems reported a very large Ł33.7 billion order intake and Ł77.8 billion backlog, reinforcing how order flow feeds future revenue visibility (BAE Systems 2024 full year results).
• L3Harris posted a smaller revenue base than the largest primes, but its $34 billion record backlog still signals a substantial work pipeline relative to its size (L3Harris Technologies Reports Fourth Quarter and Full-Year 2024 Results, Initiates 2025 Guidance).

Backlog as the clearest signal in defense

If you want one metric that best captures the defense industry from this dataset, it is backlog. Backlog is where the sector’s long-cycle nature becomes visible. It shows not only what companies sold this year, but how much work is already committed for future delivery.

Big backlog figures

• RTX: $218 billion total backlog, including $125 billion of commercial work and $93 billion of defense work (RTX Reports 2024 Results and Announces 2025 Outlook; RTX 2024 Annual Report).
• Lockheed Martin: $176.0 billion record backlog and $107.8 billion funded backlog at year-end 2024 (Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results; Lockheed Martin 2024 Annual Report).
• Northrop Grumman: $91.468 billion total backlog and $50.6 billion in net awards during 2024 (Northrop Grumman 2024 Annual Report).
• General Dynamics: $90.6 billion backlog and $53.4 billion estimated potential contract value at year-end 2024 (General Dynamics Reports Fourth-Quarter and Full-Year 2024 Financial Results).
• BAE Systems: Ł77.8 billion order backlog at year-end 2024 (BAE Systems 2024 full year results).
• L3Harris: $34 billion record backlog at year-end 2024 (L3Harris Technologies Reports Fourth Quarter and Full-Year 2024 Results, Initiates 2025 Guidance).

What backlog says about the industry

Backlog is not just a vanity number. It is the clearest signal of revenue visibility in a sector where multi-year contracts matter. The biggest backlog in this dataset belongs to RTX at $218 billion, and the second-largest belongs to Lockheed Martin at $176.0 billion. Those two numbers are materially larger than the sales figures reported for the same companies, which shows how much future work is already in the system.

That gap between current-year sales and future commitments is one of the defining features of the defense business model. For example:

• Lockheed Martin’s $176.0 billion backlog sits well above its $71.0 billion of annual net sales (Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results).
• RTX’s $218 billion backlog dwarfs its $80.8 billion revenue base (RTX Reports 2024 Results and Announces 2025 Outlook; RTX 2024 Annual Report).
• Northrop Grumman’s $91.468 billion backlog is more than twice its $41.0 billion in sales (Northrop Grumman Reports Fourth Quarter and Full-Year 2024 Financial Results; Northrop Grumman 2024 Annual Report).

That kind of gap matters because it indicates long-run program depth. In defense, companies can spend years building, sustaining, and delivering on large programs. A backlog-heavy profile can provide more predictability than a simple sales tally.

Cash flow, earnings, and capital discipline

Revenue tells you scale, but cash tells you quality. The defense industry statistics in this dataset show that several companies converted large parts of that scale into cash from operations and free cash flow. That is important because cash generation supports program investment, shareholder returns, and future capacity.

Notable cash and profit figures

• Lockheed Martin generated $7.0 billion in cash from operations and $5.3 billion in free cash flow in 2024 (Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results).
• RTX generated $2.6 billion in cash from operations and $2.3 billion in adjusted free cash flow in 2024 (RTX Reports 2024 Results and Announces 2025 Outlook).
• Northrop Grumman reported $4.4 billion in operating cash flow and $2.6 billion in free cash flow (Northrop Grumman Reports Fourth Quarter and Full-Year 2024 Financial Results).
• General Dynamics reported $3.8 billion in net earnings and $13.63 diluted EPS (General Dynamics Reports Fourth-Quarter and Full-Year 2024 Financial Results).
• BAE Systems reported Ł2,685 million operating profit under IFRS and Ł3,925 million net cash flow from operating activities under IFRS (BAE Systems 2024 full year results).
• L3Harris reported $7.87 diluted EPS and $13.10 non-GAAP diluted EPS (L3Harris Technologies Reports Fourth Quarter and Full-Year 2024 Results, Initiates 2025 Guidance).

Shareholder returns and reinvestment

This dataset also shows how mature defense companies balance reinvestment and returning cash to shareholders.

• Lockheed Martin returned $6.8 billion to shareholders through dividends and share repurchases in 2024 (Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results).
• Northrop Grumman returned $3.7 billion of cash to shareholders in 2024 (Northrop Grumman Reports Fourth Quarter and Full-Year 2024 Financial Results).
• Lockheed Martin invested over $3 billion in research and development and capital investment in 2024 (Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results).

Those figures suggest a mature industry that still needs to fund innovation and capacity, but also has enough cash generation to reward investors. That mix is common in large defense primes, where long-term contracts and engineering-heavy delivery models create the potential for stable cash flow.

Why cash flow matters in defense

Defense companies can report strong sales but still disappoint if working capital, contract timing, or margin structure weakens cash conversion. In this dataset, several firms show the opposite:

• strong sales,
• strong cash from operations,
• and meaningful free cash flow.

That combination is a sign that the business model is not purely accounting-driven. It also helps explain why backlog is paired so often with cash metrics in serious industry analysis.

Workforce scale and technical labor

The defense industry depends on large numbers of highly specialized employees. This dataset gives a useful snapshot of that labor intensity.

Workforce figures in the dataset

• Lockheed Martin had approximately 121,000 employees as of December 31, 2024, including approximately 70,000 engineers, scientists and information technology professionals (Lockheed Martin 2024 Annual Report).
• RTX had approximately 186,000 employees as of December 31, 2024 (RTX 2024 Annual Report).
• Northrop Grumman reported 4.4 billion in operating cash flow while sustaining a large workforce, underscoring the scale of its program execution model (Northrop Grumman Reports Fourth Quarter and Full-Year 2024 Financial Results).
• General Dynamics employed more than 110,000 people worldwide in 2024 (General Dynamics Reports Fourth-Quarter and Full-Year 2024 Financial Results).
• BAE Systems had around 107,400 employees in 2024 (BAE Systems Annual Report 2024).
• L3Harris employed about 50,000 people in 2024 (L3Harris Technologies Reports Fourth Quarter and Full-Year 2023 Results; L3Harris 2024 Sustainability Report).

What the labor numbers suggest

The workforce data confirms that defense is not a narrow software-style business. It is a large engineering and systems-integration industry. Lockheed Martin’s 70,000 engineers, scientists and information technology professionals are especially notable because they make the technical mix visible, not just the headcount (Lockheed Martin 2024 Annual Report).

The employee counts also help explain why revenues in this sector come with major fixed costs, long program cycles, and a premium on execution. High backlog is only useful if the organization can deliver. The workforce metrics suggest that these companies are built to do exactly that at scale.

Quick read on scale versus labor

• RTX appears to be the largest employer in the dataset at 186,000 employees (RTX 2024 Annual Report).
• Lockheed Martin has one of the most technically concentrated workforces in the dataset, with 70,000 engineers, scientists, and IT professionals (Lockheed Martin 2024 Annual Report).
• General Dynamics, BAE Systems, and L3Harris all show workforce footprints that are large enough to support multi-segment defense portfolios (General Dynamics Reports Fourth-Quarter and Full-Year 2024 Financial Results; BAE Systems Annual Report 2024; L3Harris 2024 Sustainability Report).

How to read the numbers together

Defense industry statistics are most useful when they are read as a system rather than as isolated company facts. The dataset shows a pattern that is easy to miss if you focus on one metric at a time.

The pattern across the sector

• Revenue and sales are large, but backlog is often larger.
• Cash generation is substantial enough to support reinvestment and shareholder returns.
• Workforce size remains a defining part of the business model.
• The largest contractors combine broad program portfolios with deep technical labor pools.

A simple way to interpret the data

If you are comparing companies in the defense sector, start with three questions:

1. How much revenue or sales did the company report this year?
2. How large is the backlog or order intake relative to that revenue?
3. How much cash did the company generate after operating costs and investment?

Using those questions, this dataset separates companies that merely had a strong year from companies that have a substantial runway. For example, RTX’s $218 billion backlog, Lockheed Martin’s $176.0 billion record backlog, and Northrop Grumman’s $91.468 billion backlog all point to heavy future demand already booked (RTX 2024 Annual Report; Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results; Northrop Grumman 2024 Annual Report).

At the same time, the cash flow figures show whether that booked work is translating into financial strength. Lockheed Martin’s $5.3 billion free cash flow, Northrop Grumman’s $2.6 billion free cash flow, and BAE Systems’ Ł3,925 million net cash flow from operating activities are all examples of that conversion (Lockheed Martin Reports Fourth Quarter and Full Year 2024 Financial Results; Northrop Grumman Reports Fourth Quarter and Full-Year 2024 Financial Results; BAE Systems 2024 full year results).

For readers trying to understand defense industry statistics in practical terms, the shortest answer is this: the sector is defined by large booked demand, technical depth, and the ability to turn long-cycle programs into durable cash generation.
