Defense is one of the few sectors where demand is structurally insulated from economic cycles. Nations do not reduce military spending during recessions — if anything, geopolitical stress tends to increase it. For dividend investors seeking income that survives downturns, the major defense contractors offer something rare: long-cycle government contracts, predictable cash flows, and dividend track records spanning decades.
Lockheed Martin (LMT) and Northrop Grumman (NOC) are the two most compelling income stories in the sector. Both have grown their dividends for more than 20 consecutive years. Both generate substantial free cash flow from long-term government programs. But they are more different than they appear — and those differences matter significantly for how each dividend will perform over the next decade.
The Business Behind Each Dividend
Lockheed Martin is the largest defense contractor in the world by revenue, with approximately $67 billion in annual sales. Its dominant program is the F-35 Lightning II fighter jet — the most expensive weapons program in history, with a projected total cost exceeding $1.7 trillion over its lifetime. The F-35 is sold to the U.S. military and 17 allied nations, and the maintenance, upgrade, and sustainment contracts attached to it will generate revenue for decades after production ends. Lockheed also operates significant businesses in missiles and fire control (including the Javelin and HIMARS systems that gained prominence in Ukraine), rotary wing aircraft (Sikorsky helicopters), and space systems.
The F-35's dominance is both Lockheed's greatest strength and its most significant concentration risk. The program represents roughly 25–30% of total revenue. Any technical setbacks, political disputes with allied customers, or long-term platform competition from next-generation aircraft could meaningfully affect the top line.
Northrop Grumman operates with a more diversified business mix across four segments: aeronautics (B-21 Raider stealth bomber, E-2D Advanced Hawkeye), defense systems (missiles, ammunition, battle management), mission systems (electronics, sensors, cyber), and space systems (satellites, ground systems, missile defense). No single program approaches the F-35's revenue concentration in Lockheed's portfolio.
The B-21 Raider is Northrop's flagship next-generation program — the U.S. Air Force's replacement for the aging B-2 Spirit. It is a classified program, which creates uncertainty for analysts, but the long-term trajectory is clear: the Air Force has committed to a significant fleet, and Northrop is the sole manufacturer. Space is Northrop's fastest-growing segment, benefiting from both government satellite programs and missile defense investments.
Dividend Track Records
Lockheed Martin has increased its dividend for 21 consecutive years, with a 10-year compound growth rate of approximately 8–9%. The company has been among the most consistent capital returners in the S&P 500 — combining dividends with substantial share buybacks (it has reduced its share count by roughly 40% over the past decade). The current yield sits in the 2.5–3.5% range depending on where the stock trades relative to its historical bands.
Northrop Grumman has a similarly long streak — 20+ consecutive years — but with a higher dividend growth rate: approximately 11–13% over the past decade. This reflects Northrop's faster earnings growth, driven by the expansion of its space and cyber segments and the ramp-up of the B-21 program. The current yield is typically lower than Lockheed's (1.5–2.5%), reflecting the market's higher growth expectations.
The difference in yield and growth rate is the central trade-off in this comparison: Lockheed offers more current income, Northrop offers faster income growth.
The Weiss Method Applied to Defense
Defense contractors are well-suited to Weiss analysis for several reasons. They have long, stable dividend histories. Their earnings, while not immune to volatility, are far smoother than cyclical industrials because of the long-term nature of government contracts. And the Weiss signal on both stocks has historically been a reliable indicator of entry quality.
Lockheed Martin's yield has spiked meaningfully during periods of political uncertainty — budget sequestration fears in 2012-2013, defense spending debates in 2020-2021, and periodic concerns about F-35 program delays. Each of these moments pushed the yield toward the upper end of its historical range and, in retrospect, each was a good entry point for long-term investors.
Northrop Grumman's lower yield means the Weiss signal triggers less frequently. But when it does — most notably during the broader industrial selloff of 2022, when rising rates compressed multiples across capital-intensive industries — the signal has proven equally valid.
For investors monitoring both stocks, the Weiss signal matters more on Lockheed because it appears more regularly. Northrop rarely gets cheap enough to trigger the undervalued signal, which is itself a commentary on how the market values its growth runway.
Payout Sustainability and Financial Health
Both companies generate free cash flow well in excess of their dividend obligations. Lockheed's FCF payout ratio (dividends as a percentage of free cash flow) is typically in the 40–50% range — conservative enough to sustain growth and buybacks simultaneously. Northrop's FCF payout ratio is even lower, typically 30–40%, reflecting both higher FCF generation and a lower absolute dividend cost.
Neither company faces balance sheet risk that threatens the dividend. Both carry investment-grade debt at manageable leverage ratios. Defense contractors are among the most creditworthy businesses in the industrial sector — their customer is the United States government.
The one risk worth monitoring for Lockheed specifically is the F-35 unit cost and production rate. Fixed-price development contracts have historically created cost overruns in the defense industry. Lockheed has managed this well on the F-35, but cost control remains critical to margin preservation.
The Geopolitical Tailwind
Both companies benefit from a structural shift that has been underway since Russia's invasion of Ukraine in 2022: NATO allies are increasing defense spending toward the 2% of GDP target, and some are going beyond it. European rearmament, Indo-Pacific deterrence requirements, and modernization of aging Cold War-era equipment all translate directly into backlog growth for U.S. defense primes.
Lockheed benefits most directly through international F-35 orders and HIMARS demand. Northrop benefits through satellite constellations, missile defense systems, and the B-21's classified international interest. Both backlogs are at or near record levels, providing multi-year revenue visibility that most industrial companies cannot match.
The Portfolio Decision
Own Lockheed Martin if you want higher current yield, the world's most valuable defense franchise in the F-35, and a business with extraordinary sustainment revenue locked in for decades. Accept that F-35 concentration is real and that the stock tends to trade on political and contract news more than fundamentals.
Own Northrop Grumman if you want faster dividend growth, better business diversification across space/cyber/stealth, and exposure to the next generation of U.S. military platforms (B-21, missile defense). Accept a lower starting yield in exchange for higher income growth over time.
The case for owning both is straightforward: they have limited business overlap (one is primarily aircraft and missiles, the other is stealth/space/cyber), they both benefit from the same geopolitical tailwind, and holding both provides income diversification across the two most important segments of U.S. defense investment. For a dividend portfolio built for 15–20 years, this is a low-regret combination.
Defense is rarely exciting. That is precisely why it works so well in an income portfolio.
