The iShares U.S. Aerospace & Defense ETF (ITA) commands $6.23 billion in net assets, and that number alone tells you something important about where serious money is flowing. Defense ETFs have quietly become one of the more compelling corners of the market for investors who want stable income backed by the kind of budgets that never really shrink. These specialized funds focus on companies in the military and defense sectors, from aerospace giants to weapons manufacturers, and while they’ve lagged the broader market at times, they tap into a spending engine powered by some of the largest government budgets on earth.

Defense ETFs give you a direct route into military and defense industry stocks without the stress of picking individual winners. They cover a wide spectrum, from leading aerospace firms to entities deep in weapons production and defense technology. That variety means broad exposure to an industry that doesn’t disappear when economic cycles turn. And because the underlying companies often operate on long-term government contracts, the revenue profile looks very different from your typical growth stock.

Understanding Defense ETFs

Defense ETFs have become a go-to option for investors who want real exposure to aerospace and defense without the risk of concentrating everything into one or two names. You get a broad stake in companies building military technology, armaments, and aerospace systems, including businesses specializing in guided missile systems. Think of it as buying the whole ecosystem rather than betting on a single player.

What Are Defense ETFs

Defense ETFs are exchange-traded funds built specifically around the defense sector, covering everything from armaments and defense technology to aerospace equipment, cybersecurity, and unmanned vehicles. They track indexes designed for this space, such as the MarketVector™ Global Defense Industry Index and the MarketVane Defense Index, which set clear criteria for the kinds of companies that qualify.

Why Invest in Defense ETFs?

The case for defense ETFs comes down to one word: predictability. Government-backed demand doesn’t evaporate when consumer sentiment dips or when tech stocks correct. That consistency flows through to steady income and dividends for investors. Funds like the VanEck Defense UCITS ETF and the HANetf Future of Defence UCITS ETF, both domiciled in Ireland, give you access to this dynamic without you having to manage individual positions.

Market Performance and Trends

Defense ETF performance tends to track the broader defense industry closely, and lately that industry has been moving. The MarketVector™ Global Defense Industry Index posted a 51.69% gain over one year, with a 5.20% rise in a single month. Specific funds followed suit. The VanEck Defense UCITS ETF gained 22.46% in 2024, while the HANetf Future of Defence UCITS ETF delivered a 17.08% return over the same period.

When you start comparing funds, the details matter. The Invesco Aerospace & Defense ETF (PPA) posted the highest one-year return at 26.8%. The SPDR S&P 500 Aerospace & Defense ETF (XAR) wins on cost efficiency with an expense ratio of just 0.35%. And if liquidity is your priority, the iShares U.S. Aerospace & Defense ETF (ITA) leads the pack with 452,818 shares traded daily and $5.8 billion in assets under management.

Those numbers matter. Defense ETFs offer stability rooted in government contracts and a relentless appetite for new defense technology, which makes them worth considering as a core holding rather than just a tactical trade.

Top Defense ETFs in the Market

A few names consistently rise to the top when you’re building a strategic defense allocation. The iShares U.S. Aerospace & Defense ETF (ITA), the Invesco Aerospace & Defense ETF (PPA), and the SPDR S&P Aerospace & Defense ETF (XAR) stand out for their combination of strong performance, high liquidity, and competitive fees.

iShares U.S. Aerospace & Defense ETF (ITA)

ITA is the heavyweight of the group. With $6.23 billion in net assets as of May 2024, a 30-day average daily volume of 452,818, and an expense ratio of 0.39%, it gives you serious scale and tradability. The top five holdings account for 55% of total assets, so you get meaningful exposure to the sector’s biggest names without excessive dilution.

Invesco Aerospace & Defense ETF (PPA)

If performance is your benchmark, PPA is hard to ignore. A one-year return of 26.8% puts it ahead of the pack. It manages around $3.178 billion in assets with an expense ratio of 0.58%, and its top five holdings make up 30.8% of the portfolio. That’s a more balanced concentration than ITA, which some investors will prefer.

SPDR S&P Aerospace & Defense ETF (XAR)

XAR makes a compelling case if you’re watching costs. At a 0.35% expense ratio, it’s the most affordable option in this group, and its $2.11 billion in assets confirms it’s no fringe product. With the top five holdings covering just 21.7% of assets and 65 total positions, XAR offers the widest diversification across the aerospace and defense sector of the three.

Focusing on these top defense ETFs lets you diversify your portfolio with purpose. You get exposure to a sector known for consistency and steady growth. Whether you’re prioritizing performance, keeping costs low, or aiming for a balanced position, these three funds cover the ground well.

How To Invest In Defense ETFs

Defense ETFs appeal to investors who want military and aerospace exposure without picking individual stocks. They give you access to a sector funded substantially by the U.S. government, blending stability with long-term growth potential. Here’s how to approach them the right way.

Step-by-Step Investment Guide

A methodical approach makes all the difference when you’re putting money into defense ETFs.

Start by defining your goals. Are you after growth, income, or a mix of both? That answer shapes everything. From there, dig into performance histories. The iShares U.S. Aerospace & Defense ETF (ITA) posted a 25.1% gain, while the SPDR S&P 500 Aerospace & Defense ETF (XAR) returned 24.1%. Those numbers give you a starting point for comparison.

Don’t skip expense ratios and yields since they compound over time. ITA sits at 0.39%, while XAR comes in at 0.35%. Liquidity matters too, because you want to be able to enter and exit positions cleanly. And take a close look at how diversified each fund actually is. A well-spread portfolio can soften the blow when individual names underperform. You might also find it useful to understand how index rebalancing works and what it means for your returns.

Choosing the Right ETF

Picking the right defense ETF is less about finding the “best” one and more about matching the fund to your situation.

If you want steady income, lean toward ETFs with stronger yield profiles like ITA. If minimizing costs is the priority, XAR’s 0.35% expense ratio makes it the natural choice. And if past performance is your guide, PPA’s 26.8% one-year track record speaks for itself.

Think about market exposure as well. A fund that blends different company sizes gives you a more balanced risk and return profile. ITA, for instance, holds major players like Boeing and Lockheed Martin. Getting into defense ETFs requires real analysis, but the payoff in portfolio stability and sector growth can be worth it.

Benefits of Investing in Defense ETFs

Defense ETFs bring a set of genuine advantages that make them worth a close look, especially if you’re building a portfolio that needs to weather uncertainty. Stability and income potential are the headline draws, but the benefits run deeper than that.

Diversification

One of the strongest arguments for defense ETFs is diversification. Instead of concentrating risk in a single defense name, you spread your exposure across dozens of companies in the aerospace and defense sectors. Firms like Boeing, Lockheed Martin, and Raytheon Technologies all contribute to the collective performance, which smooths out the bumps that any one stock might hit.

The iShares U.S. Aerospace & Defense ETF (ITA) manages $5.8 billion in assets, while the SPDR S&P 500 Aerospace & Defense ETF (XAR) trades at an average daily volume of 57,658 shares. Both give you a diversified entry point into the defense industry without the concentration risk of going stock by stock.

Reliable Revenue Streams

Government contracts are the backbone of defense company revenues, and that’s a significant advantage for investors. Statista tracks the steady growth in the U.S. defense budget since 2017, and that trend looks set to extend through 2032. Companies inside aerospace ETFs and defense funds benefit from that long-duration spending in ways that most commercial businesses simply can’t match.

That consistency shows up as stable financial performance for investors. When the underlying companies know their revenue years in advance, it creates a very different risk profile from market-dependent businesses.

Stable Income and Dividends

Defense ETFs often deliver attractive dividend yields, a natural result of the long-term, capital-intensive nature of defense projects. When companies are locked into multi-year government programs, they generate predictable cash flows, and a portion of that flows back to you as a shareholder.

Risks and Considerations

Defense ETFs offer real advantages, but you’d be doing yourself a disservice by ignoring the risks. When you’re putting money into defense contractors through an ETF structure, understanding the full picture is what separates a good decision from a costly one.

Market Risks

Market risks are real here. Geopolitical tensions and shifts in government budgets can create meaningful volatility. The MarketVector™ Global Defense Industry Index spans sectors from aerospace to cybersecurity, but it requires companies to clear a market cap above $1 billion and a monthly trading volume of at least 250,000 shares. That filter adds a layer of quality control, but it doesn’t eliminate market-driven swings.

Ethical and Moral Considerations

For some investors, the ethical dimension of defense investing is a genuine concern. Companies in this space are often deeply involved in weapons development and military technology, which can sit uneasily alongside certain values or mandates. The MarketVector™ Global Defense Industry Index does screen out firms that seriously breach UN Global Compact Principles, but the connection to arms and military operations won’t fit every investor’s ethical framework.

Performance Volatility

Performance in defense ETFs can move with shifts in government spending priorities and geopolitical developments. The MarketVector™ index caps individual company weights at 8% to manage concentration risk, but volatility in the broader defense sector can still work its way through to your returns. It’s worth going in with realistic expectations rather than assuming the government contract backing makes these funds immune to market swings.

Detailed Review of the Best Defense ETFs

Getting a real read on defense ETFs means going beyond the headlines and looking at the actual numbers. Performance metrics, top holdings, and expense ratios together give you the clearest picture of which funds deserve a place in your portfolio.

Performance Metrics

Net assets and liquidity are two of the most telling indicators of an ETF’s market standing. The iShares U.S. Aerospace & Defense ETF leads with $6.23 billion in assets as of May 2024. The Invesco Aerospace & Defense ETF follows with approximately $3.178 billion. The SPDR S&P Aerospace & Defense ETF sits at around $2.11 billion, rounding out the top three.

Smaller funds occupy interesting niches further down the list. The ARK Space Exploration & Innovation ETF holds $249.3 million in assets. The Direxion Daily Aerospace & Defense Bull 3X Shares and the SPDR S&P Kensho Future Security ETF report $156.9 million and $55.7 million respectively.

Top Holdings

Looking at top holdings reveals a lot about focus and risk. The iShares U.S. Aerospace & Defense ETF holds 38 stocks, with the top five accounting for over 55% of assets. The Invesco Aerospace & Defense ETF holds 52 stocks, where the top five make up 30.8% of the portfolio. Understanding how concentration risk plays out during market stress is essential before committing capital.

The SPDR S&P Aerospace & Defense ETF carries 65 holdings, with the top five representing 21.7% of assets. The ARK Space Exploration & Innovation ETF’s top five holdings account for 39% of its portfolio. The Direxion Daily Aerospace & Defense Bull 3X Shares and the SPDR S&P Kensho Future Security ETF see their top five holdings make up 54.7% and roughly 33% respectively.

These metrics matter more than most investors realize. High asset levels signal institutional confidence, and diverse holdings reduce the drag of any single name underperforming. Whether you’re focused on defense technology or guided missile systems exposure, getting these numbers right is the foundation of a solid long-term position.
