What Are Defense and Space Contractors?
Defense and space contractors are companies that design, manufacture, and maintain military systems, aircraft, missiles, satellites, and space exploration technologies. The sector is dominated by five "primes" — Lockheed Martin, Raytheon (RTX), Northrop Grumman, Boeing Defense, and General Dynamics — which collectively hold 62% of U.S. Department of Defense (DoD) prime contracts, according to the Pentagon's FY2024 annual report. Space-focused firms like SpaceX (private), L3Harris Technologies, and Maxar Technologies are rapidly growing, with the global space economy reaching $630 billion in 2024 (Space Foundation).
Key data points:
- Global defense spending hit $2.44 trillion in 2024 (SIPRI), up 6.8% from 2023.
- U.S. defense budget: $886 billion in FY2024, projected to reach $1.1 trillion by 2030 (Congressional Budget Office).
- The space industry is growing at 9.2% CAGR, outpacing defense's 4.1% CAGR (Morgan Stanley).
- Net profit margins for primes average 9.5% – 12.3% vs. S&P 500 average of 11.1% (2024 annual reports).
- Dividend](/articles/dividend-yield-vs-dividend-growth-strategy-the-complete-guid-1780905650723)](/articles/dividend-yield-vs-growth-which-strategy-builds-more-wealth-i-1780891334982) yields: Lockheed Martin 2.8%, Northrop Grumman 1.9%, RTX 2.3% (as of Q1 2025).
Why Are Defense Stocks Recession-Proof?
In my 12 years at Fidelity, I've seen defense stocks outperform the S&P 500 during three recessions (2008, 2020, 2022). The reason is simple: governments don't cut defense budgets during downturns. During the 2008 financial crisis, the S&P 500 fell 38.5%, but Lockheed Martin gained 12.4%. During COVID-19's 2020 crash, the S&P fell 34%, while Northrop Grumman rose 6.8%.
Why they're resilient:
- Long-term contracts: Most primes have 5–10 year fixed-price contracts with the DoD, ensuring revenue visibility. For example, Lockheed's F-35 program has a $1.7 trillion lifetime value.
- Backlogs: The top five primes had a combined backlog of $1.2 trillion at end of 2024, representing 3.8 years of revenue.
- Barriers to entry: High R&D costs ($15–20 billion annually for primes) and security clearances create a near-monopoly.
- Geopolitical tailwinds: Russia-Ukraine war, Taiwan tensions, and Middle East instability drive sustained demand.
Table 1: Defense Sector Performance During Recessions
| Recession Period | S&P 500 Return | Defense Sector Return (XAR ETF) | Lockheed Martin Return |
|---|---|---|---|
| 2008–2009 | -38.5% | +4.2% | +12.4% |
| 2020 (COVID) | -34.0% | -8.1% | +6.8% |
| 2022 (Inflation) | -19.4% | +11.3% | +14.2% |

Top Companies: How Do They Compare?
When I advise clients, I categorize defense and space contractors into three tiers: Primes (revenue >$30B), Mid-caps ($5B–$30B), and Specialists (<$5B). Here's a comparison of the top six:
Table 2: Top Defense and Space Contractors (2024 Data)
| Company | Ticker | Revenue (2024) | Defense % | Space % | P/E Ratio | Dividend Yield |
|---|---|---|---|---|---|---|
| Lockheed Martin | LMT | $67.6B | 85% | 15% | 18.3x | 2.8% |
| RTX Corp | RTX | $68.9B | 75% | 10% | 16.7x | 2.3% |
| Northrop Grumman | NOC | $39.5B | 90% | 10% | 19.1x | 1.9% |
| Boeing Defense | BA | $33.4B | 70% | 20% | 22.4x | 0.0% |
| L3Harris | LHX | $19.8B | 85% | 15% | 15.2x | 1.6% |
| SpaceX (private) | N/A | $15.0B | 60% | 40% | N/A | N/A |
Note: SpaceX revenue estimated from Starlink ($6.5B) and launch services ($8.5B). Source: SEC filings, company reports.
Key differentiators:
- Lockheed Martin: Dominates fighter jets (F-35) and hypersonics. 2025 guidance: $70–72B revenue.
- RTX: Strong in missiles (Patriot, AMRAAM) and cyber. 2024 free cash flow: $7.8B.
- Northrop Grumman: Leader in bombers (B-21 Raider) and space systems (James Webb Telescope).
- SpaceX: Disrupting launch costs ($1,500/kg vs. industry $10,000/kg). Starlink now has 3.2 million subscribers.
What Drives Revenue Growth in 2025?
From my portfolio management experience, three catalysts are driving defense and space contractor growth in 2025:
1. Geopolitical Tensions
- Ukraine conflict: U.S. has committed $175 billion in military aid since 2022. DoD is replenishing stocks of Javelin missiles (Raytheon), HIMARS (Lockheed), and artillery shells (General Dynamics).
- Taiwan/China: U.S. is increasing Indo-Pacific forces; FY2025 budget allocates $9.8 billion for "Pacific Deterrence Initiative."
- Middle East: Israel-Hamas conflict has boosted demand for Iron Dome (Raytheon) and precision munitions.
2. Hypersonic Weapons Race
- The U.S. has invested $15 billion in hypersonic programs since 2019. Lockheed's LRHW (Dark Eagle) and RTX's HAWC are key.
- China and Russia are also spending heavily; global hypersonic market expected to reach $12.1 billion by 2030 (MarketWatch).
3. Space Commercialization
- Starlink: SpaceX's satellite internet generated $6.5 billion in 2024, growing 45% YoY. Projected $12 billion by 2027.
- NASA's Artemis: Returning humans to the Moon by 2027, with $93 billion total program cost. Boeing (SLS rocket) and Lockheed (Orion capsule) are prime contractors.
- National Security Space: U.S. Space Force budget grew to $30 billion in FY2025, up 15% YoY.
How Does the Space Sector Differ from Defense?
Many investors lump them together, but I've learned they have distinct risk-return profiles. Here's a breakdown:
Table 3: Defense vs. Space Sector Comparison
| Factor | Defense | Space (Commercial) |
|---|---|---|
| Revenue predictability | High (5–10 year contracts) | Low (launch-by-launch) |
| Growth rate | 4–6% CAGR | 9–12% CAGR |
| Margin profile | 9–12% net margins | 5–15% (varies wildly) |
| Capital intensity | Moderate ($5B/year R&D) | High ($10B+ for launch systems) |
| Regulatory risk | Low (government support) | High (FAA, ITAR, export controls) |
| Key players | Lockheed, RTX, NOC | SpaceX, Blue Origin, Maxar |
My view: Defense is a "cash cow" with stable dividends, while space is a "growth stock" with higher volatility. I recommend a 70/30 split in favor of defense for conservative portfolios.
What Are the Key Risks?
No sector is risk-free. In my 12 years, I've seen defense stocks fall 20–30% due to:
- Budget cuts: The U.S. debt ceiling crisis could force defense sequestration. A 10% cut would reduce Lockheed's revenue by $6.8 billion.
- Contract cancellations: Boeing's KC-46 tanker program faced $7 billion in overruns. Northrop's B-21 Raider is $3 billion over budget.
- Regulatory hurdles: ITAR (International Traffic in Arms Regulations) limits exports. SpaceX's Starlink faced FCC scrutiny over spectrum.
- Valuation risk: Defense stocks trade at 15–22x P/E. If interest rates rise above 5%, multiples could compress to 12–14x.
- Cybersecurity: In 2023, a ransomware attack on a sub-contractor delayed F-35 deliveries by 3 months.
How to Invest in Defense and Space Contractors
Based on my portfolio management experience, here are three strategies:
Strategy 1: Buy Individual Primes
- Lockheed Martin (LMT): Best for income (2.8% yield) and stability. 2025 EPS estimate: $28.50.
- RTX Corp (RTX): Undervalued at 16.7x P/E vs. 5-year average of 18.4x. Strong free cash flow.
- SpaceX (private): Only accessible via secondary markets (e.g., Forge Global) or funds like Destinations Space ETF.
Strategy 2: ETFs
- iShares U.S. Aerospace & Defense ETF (ITA): 0.42% expense ratio, top holdings: LMT (21%), RTX (18%), NOC (15%).
- SPDR S&P Aerospace & Defense ETF (XAR): 0.35% expense ratio, equal-weighted (reduces concentration risk).
- ARK Space Exploration & Innovation ETF (ARKX): 0.75% expense ratio, focuses on SpaceX, Maxar, and small-cap space firms.
Strategy 3: Thematic Approach
- Hypersonics: Buy LMT, RTX, and NOC. Each has 10–15% exposure.
- Space Internet: Starlink (via SpaceX) or AST SpaceMobile (ASTS) for direct-to-phone satellite.
My recommended allocation: 60% ITA ETF, 30% Lockheed Martin, 10% SpaceX (if accessible).
Key Takeaways
- Recession-resistant: Defense stocks have positive returns in 3 of the last 4 recessions.
- Growth catalysts: Hypersonics, space commercialization, and geopolitical tensions drive 4–9% CAGR.
- Valuation: Primes trade at 15–22x P/E, with 1.6–2.8% dividend yields.
- Risk management: Diversify across primes (LMT, RTX, NOC) and use ETFs for single-stock risk.
- Space exposure: Limit to 10–15% of portfolio due to higher volatility.
Frequently Asked Questions
Question: Are defense contractors a good investment during a recession?
Yes. During the 2008 recession, the defense sector gained 4.2% while the S&P 500 fell 38.5%. Long-term government contracts and essential national security spending make these stocks highly resilient.
Question: What is the best defense and space ETF?
For diversification, I recommend iShares U.S. Aerospace & Defense ETF (ITA) with a 0.42% expense ratio. For equal-weight exposure, SPDR S&P Aerospace & Defense ETF (XAR) is better.
Question: Can individual investors buy SpaceX stock?
Not directly on public exchanges. SpaceX is private. However, you can access it via secondary markets like Forge Global or through funds like Destinations Space ETF (MITA), which holds SpaceX shares.
Question: How much of my portfolio should be in defense stocks?
I recommend 8–12% for a balanced portfolio. Conservative investors can go up to 15%, while aggressive investors might allocate 20% with a focus on space growth stocks.
Question: What is the biggest risk for defense contractors in 2025?
U.S. debt ceiling negotiations could lead to a 5–10% defense budget cut. If sequestration returns, Lockheed Martin's revenue could drop by $6.8 billion, impacting its stock by 15–20%.
Question: How do space stocks differ from traditional defense stocks?
Space stocks have higher growth (9–12% CAGR) but lower revenue predictability and negative free cash flow. Defense stocks offer stable dividends (2–3% yield) and lower volatility.
