For the foreseeable future, there will be demand for defense companies and the products they make. Defense stocks tend not to be as glamorous as high-growth sectors, such as tech. However, they provide reliable revenue and income from a customer -- the U.S. government -- with a seemingly insatiable appetite for their products.
Defense stocks tend to be stable contributors to an income-focused portfolio. Their predictable long-term revenue streams translate into solid dividends and healthy returns for investors. Defense ETFs are a type of investment that holds a basket of defense stocks, allowing investors to gain exposure to multiple stocks in the sector instead of having to choose between the various companies.
Since no single defense contractor makes everything, an investor would have to buy shares in all the largest defense companies to gain full exposure to the sector. With that in mind, it might make more sense to invest in defense through an exchange-traded fund (ETF) that gives you a small interest in a large number of companies with ties to the aerospace and defense market.

Why invest
Why invest in defense ETFs?
There is solid, sustainable demand for both commercial and defense equipment, and top companies should be able to provide a steady stream of income and growth for long-term focused investors. But deciding between individual companies is difficult. And with both commercial aerospace and defense companies primarily serving a small number of customers, the stocks tend to move in unison based on demand.
Investing in defense ETFs allows you to gain exposure to those long-term growth trends without having to pick winners and losers among individual companies.
How to choose
How to choose defense ETFs
All these ETFs are broadly in the same category, but they contain different holdings driven by different themes. Investors should look for ETFs that cater to their specific interests, considering factors such as whether:
- The ETF is more focused on commercial or defense holdings.
- The ETF focuses on parts suppliers or prime manufacturers.
- The ETF is looking for growth, income, or a mix of the two.
- The ETF is focused on higher risk, higher reward disruptors or traditional manufacturer.
- The ETF is focused on companies doing business in the U.S., elsewhere, or both.
Investors can find the answers to these questions by visiting each ETF's website, where they will find a list of holdings and a paragraph discussing investment themes and goals.
You should also pay close attention to fees. ETF fees can vary from fund to fund and from company to company, and higher fees will make it harder for an ETF to beat the market.

Should I invest?
Are defense ETFs right for you?
When markets get volatile, it's nice to have a little diversification in your portfolio. Defense ETFs, like ETFs focused on the broader industrials sector, are unlikely to generate market-beating returns day in and day out. However, they do provide a basket of companies that tend to perform well in challenging times and offer a steady stream of income throughout the cycle.
The world can be a dangerous place. Investors may sleep better knowing that their portfolios contain companies designed to keep them safe when times get tough.
FAQ
Defense ETFs FAQ
What is the highest-rated defense ETF?
There is no single way to rate ETFs. Investors looking for the largest defense ETF should consider the iShares U.S. Aerospace & Defense ETF. Those interested in past performance and willing to accept added risk would likely view the Direxion Daily Aerospace & Defense Bull 3X Shares -- the top-performing of these choices during the 12 months ending July 2025 -- as the best choice.
Is there a military defense ETF?
Most of the defense ETFs also have substantial commercial aerospace exposure. However, the Kensho Future Security ETF is an intriguing option for investors focused solely on military security and cybersecurity.
Which is better, the iShares ETF or Invesco ETF?
Both are solid, but they offer slightly different options for investors. The iShares fund has a lower expense ratio, which is an important factor any time you are looking at ETFs. However, its two largest holdings are tied closely to the commercial aerospace sector, not defense. So, the Invesco ETF could be a better choice for investors most interested in defense companies.
Does Vanguard have a defense ETF?
Vanguard offers a number of industrial-focused ETFs that provide exposure to some defense companies, but it does not offer a standalone, defense-focused ETF. The other ETFs listed here can be purchased through a Vanguard account.
Is there an ETF for defense stocks?
There are a number of defense-related ETFs, including those featured on this page. However, it should be noted that most defense ETFs also have commercial aerospace exposure and are not pure-play defense investments. The Kensho Future Security ETF is an option for investors focused solely on military security and cybersecurity.
What is the best defense stock?
Choosing the best stock for everyone is difficult because each investor has their own unique set of circumstances. But speaking generally, Lockheed Martin and Northrop Grumman are considered the top choices for long-term investors seeking exposure to individual names among the defense prime contractors.
Are defense ETFs suitable for long-term investors?
Defense is a very long-cycle business, with it sometimes taking five years or longer for new contract awards to translate into revenue. That characteristic, coupled with the ability of defense stocks to pay stable dividends, makes defense ETFs best for long-term investors instead of market timers.
How do defense ETFs perform during war or geopolitical conflict?
Not surprisingly, when war is in the news, defense stocks tend to get a lot of attention. And defense ETFs tend to see a surge when a conflict breaks out. However, those surges are hardly ever sustainable, since new defense equipment takes years to be produced and there is usually very little impact on near-term numbers.
Arguably, defense stocks do better in times of peace because government investment in research and development (R&D) tends to be higher-margin for the companies than the government simply buying replacements for used equipment.
