Best defense ETF: how to compare funds
The best defense ETF is the one whose mandate, concentration, fee, and holdings overlap match the role you need in a portfolio.
Use case decides the best defense ETF
Use case decides the best defense ETF because the fund universe splits into broad aerospace, modified equal-weight defense, defense technology, and drone-specific mandates.
The iShares U.S. Aerospace & Defense ETF is a broad U.S. aerospace and defense fund. The State Street SPDR S&P Aerospace & Defense ETF tracks a modified equal-weight aerospace and defense index. The Invesco Aerospace & Defense ETF tracks an issuer-listed aerospace and defense index.
For newer defense technology, the Global X Defense Tech ETF and Defiance JEDI ETF are more explicit about modern military technology themes.
Defense ETF comparison framework
| Investor question | Fund type to research | Watch for |
|---|---|---|
| I want traditional U.S. primes. | ITA, XAR, or PPA. | Prime-contractor concentration and index weighting method. |
| I want defense technology. | SHLD or JEDI. | Theme definitions, holdings turnover, and smaller-company exposure. |
| I want drone exposure. | DRNZ first, then JEDI. | Drone purity, fund age, and overlap with existing holdings. |
| I want lower single-name concentration. | Equal or modified equal-weight approaches. | Rebalance rules and smaller-company weights. |
ITA vs XAR vs PPA vs SHLD: Which to Pick
No single defense ETF is universally superior because each vehicle serves a distinct allocation goal through its index construction. ITA and XAR hold the same industry but weight it in opposite ways. ITA uses capped market-cap weighting, putting 36.96% of fund assets into GE Aerospace and RTX combined as of October 1, 2026.
The XAR ETF tracks a modified equal-weighted index, keeping each prime contractor around a 2.8% to 2.9% weight. That modified equal weighting gives XAR a 5.69% combined allocation to AeroVironment and Kratos Defense & Security Solutions, compared to 1.04% in ITA. If you want domestic primes to drive fund returns, ITA fits. If you want mid-tier and smaller suppliers to carry equal weight, XAR fits.
ITA and PPA differ in how wide a mandate they cover and in what they charge. ITA limits its portfolio to domestic aerospace and defense manufacturers. The PPA ETF tracks the SPADE Defense Index, which covers companies that develop, make, operate or support U.S. defense, homeland security and government space operations.
PPA showed 67 holdings lines on October 1, 2026, including a money market fund line and a securities-lending line. Its index had 61 constituents as of June 30, 2026. Its holdings include foreign defense contractors listed on U.S. exchanges, such as Israel-based Elbit Systems at 2.72% alongside Canadian firms CAE and MDA Space. However, PPA charges a 0.58% total expense ratio.
That sits 21 basis points higher than ITA at 0.37% and 23 basis points above XAR at 0.35% gross. PPA fits if you want homeland-security and space names in the basket and accept the higher fee for them.
SHLD reaches into defense software, which ITA's aerospace-and-defense index barely touches. SHLD tracks the Global X Defense Tech Index, which requires constituents to earn at least 50% of aggregate revenue from cybersecurity, defense technology like artificial intelligence (AI), or advanced systems and robotics.
That mandate generated a 14.6% allocation to information technology as of August 31, 2026, led by Palantir Technologies at 11.98% of net assets on October 1, 2026. iShares puts 99.88% of ITA's market value in the Aerospace & Defense sector as of September 30, 2026, and its sector breakdown lists no software line.
SHLD charges a 0.50% total expense ratio across 50 holdings, offering an alternative for investors who want digital warfare and autonomous systems exposure instead of conventional equipment builders.
Each fund carries specific trade-offs that dictate who should avoid it. If your risk tolerance cannot handle concentrated valuation swings from software holdings, SHLD is the wrong fund, and ITA is the closer fit. If you want drone makers specifically, all four funds dilute them (AeroVironment plus Kratos peaks at 5.69% in XAR), and the best drone ETF comparison covers dedicated funds.
Before placing a trade, check current weights in the holdings files for ITA, XAR, PPA and SHLD. Price moves can push a stock above its index cap between rebalances: Palantir's 11.98% in SHLD on October 1, 2026 sat above that index's 8% rebalance cap.
| Fund | Index and Weighting | Expense Ratio | Holdings | AeroVironment + Kratos Weight | Who It Fits |
|---|---|---|---|---|---|
| ITA | Dow Jones U.S. Select Aerospace & Defense Index (capped market cap) | 0.37% | 50 as of Sep 30, 2026 | 1.04% as of Sep 30, 2026 | Investors seeking concentrated exposure to large U.S. prime defense contractors. |
| XAR | S&P Aerospace & Defense Select Industry Index (modified equal weight) | 0.35% gross | 50 as of Oct 01, 2026 | 5.69% as of Oct 01, 2026 | Investors wanting equalized exposure across small- and mid-cap defense suppliers. |
| PPA | SPADE Defense Index (modified market cap) | 0.58% | 67 lines as of Oct 01, 2026 (61 index constituents as of Jun 30, 2026) | 1.18% as of Oct 01, 2026 | Investors wanting broad defense scope, including homeland security and select U.S.-listed allies. |
| SHLD | Global X Defense Tech Index (modified market cap, 8% rebalance cap) | 0.50% | 50 as of Oct 01, 2026 | 2.11% as of Oct 01, 2026 | Investors targeting defense technology, software, cybersecurity, and unmanned systems over traditional primes. |
Index weighting changes the fund more than the fund name does
Two funds covering the same aerospace and defense sector can behave differently purely because of how their indexes assign weight. A cap-weighted approach of the kind the iShares U.S. Aerospace & Defense ETF uses gives the largest companies the largest positions, so the fund tracks the fortunes of a handful of primes and a bad quarter at one of them moves the whole portfolio.
A modified equal-weight approach of the kind the State Street SPDR S&P Aerospace & Defense ETF tracks starts from roughly similar position sizes and caps how far any one name can drift.
Work through what that means: if a mid-sized supplier and a prime are both in the index, the equal-weighted fund gives the supplier a position comparable to the prime's, so smaller and more cyclical companies drive far more of the return than their market value would suggest. The same sector, the same tickers, and a materially different risk profile.
That is also why comparing recent performance between the two tells you less than it appears to. A stretch in which smaller suppliers outperform flatters equal weighting; a stretch in which the primes lead flatters cap weighting. Neither outcome says the index rule was better, only that the cycle happened to favor one construction.
Confirm the current weighting method and any cap rules on the issuer pages, since methodologies are revised.
What “defense technology” means as an index rule
Defense technology is an index definition rather than an industry classification, which is why two defense-tech funds can look unlike each other. Sector-based indexes pull from an established classification scheme, but a theme index has to write its own eligibility test — typically some combination of business description, revenue derived from qualifying activities, and a committee judgment about whether a company belongs.
The Global X Defense Tech ETF and the Defiance JEDI ETF both write that test, and the differences in wording are what produce different portfolios: whether commercial as well as military applications qualify, whether software and cyber count alongside hardware, whether non-U.S. contractors are eligible, and how strictly a revenue threshold is applied.
A loose test admits large incumbents and makes the fund resemble a broad defense fund; a strict test concentrates the portfolio in specialists.
The related consequence is turnover. A theme defined by a committee gets re-examined at every reconstitution, so holdings can rotate faster than in a classification-driven sector fund, and the reader who bought a mandate should re-read the methodology document rather than assuming the roster is stable.
Why “best” should not mean recent winner
Best should not mean recent chart winner because short-term fund moves can reflect a defense cycle, one large holding, or market sentiment. Those are not the same as mandate fit. This page's fund list is chosen for research value — see the disclaimer for how we select and describe funds.
A stronger screen asks whether the ETF owns the defense segment you are studying. Then it checks whether the cost and concentration are acceptable for that role. Once you have chosen a fund, the guide on how to buy drone stocks covers the order-placement steps, which work the same way for ETF shares.
How drone exposure fits defense ETFs
Drone exposure fits defense ETFs as either a direct theme or an indirect slice of a larger aerospace fund. Direct exposure can be more volatile, while broad exposure can dilute the drone thesis.
Readers focused on unmanned systems should pair this page with the drone ETF list and the unmanned systems hub. Anyone deciding between this kind of fund and individual stocks should also see the drone ETF vs. stocks guide.
ETF FAQ
What is the best defense ETF?
The best defense ETF depends on whether you want broad aerospace, defense technology, modern warfare, or drone-specific exposure.
Are defense ETFs good drone investments?
Defense ETFs can provide indirect drone exposure, but only drone-focused funds or modern-warfare funds make the theme more explicit.
What should I check before choosing a defense ETF?
Check the issuer mandate, index rules, holdings concentration, fees, fund age, and overlap with other funds you own.
To check overlap concretely, list each fund's top-10 holdings from its own fact sheet on the same date and see how many repeat between funds; concentrated thematic funds like SHLD and JEDI often share the same large-cap defense primes, so adding a second fund can add less diversification than its different ticker suggests.
What is the difference between a defense ETF and an aerospace ETF?
In practice most U.S. funds combine the two into a single aerospace and defense index, so the labels often describe the same fund. Where they differ, an aerospace mandate can reach commercial aircraft, engines, and parts suppliers whose customers are airlines rather than governments, while a defense-only or defense-technology mandate screens for military and government revenue.
Read the index methodology to see which revenue actually qualifies. On this page "best" means best to research, not best to buy.
What is the expense ratio for ITA, XAR, PPA, SHLD, or JEDI?
Expense ratios are not listed on this page, because they can change and the issuer page is the only current source. Open each fund's summary prospectus or fact sheet directly — the fund links in the facts panel point to the issuer's own page — and compare the live number, not a cached figure from a screener.
A small ratio difference matters less than mandate fit, but it still compounds over a long holding period.
Do these defense ETFs pay dividends?
Dividend policy is not the same across these funds, and it is not shown on this page. Pull the distribution history and current yield from each issuer's own fund page, since aggregator sites can lag the official number. Whether a payout matters to you depends on whether you are buying this theme for income or for growth.
Do these defense ETFs hold only U.S. companies, or is there foreign exposure too?
It depends on the fund, and the mandate name alone does not tell you. A broad aerospace and defense index can include non-U.S. contractors if the index rules allow it. A stricter U.S.-focused mandate screens foreign companies out. Check the country breakdown on each issuer's fact sheet before assuming any fund here is a pure U.S. defense play.
Is DFEN a leveraged defense ETF, and is it the same fund as VanEck's "Defense ETF"?
No, and the ticker overlap is genuinely confusing. On NYSE Arca, DFEN belongs to Direxion's Daily Aerospace & Defense Bull 3X Shares, a leveraged fund from Direxion that uses derivatives to seek 300% of the daily return of the Dow Jones U.S. Select Aerospace & Defense Index.
None of the funds compared on this page (ITA, XAR, PPA, SHLD, JEDI) are leveraged or inverse products; they hold company shares directly under an index or mandate. Separately, VanEck's unleveraged Defense UCITS ETF also happens to use the ticker DFEN, but on the Xetra exchange in Germany rather than on a U.S. exchange, so venue is what tells the two apart, not the letters.
See the European defense ETF guide for VanEck's fund and its other exchange tickers.
A 3x fund like Direxion's resets its leverage daily, so its return compounds day over day rather than tracking the index in a straight line: over any stretch longer than one trading day, the fund's cumulative return can diverge meaningfully from 3x the index's cumulative return for that same stretch, and the gap tends to widen in choppy or volatile markets even when the underlying index ends up roughly flat.
That daily-reset mechanic is documented in Direxion's own fund materials, not a market forecast. Before buying any ticker with "defense" in the name, confirm on the issuer's own fund page whether it is a standard index fund or a leveraged product, and on which exchange it trades.
Is JEDI pure drone exposure, or broader defense-tech exposure?
Broader. JEDI's mandate spans drones, unmanned systems, AI-driven warfare, cyber, space, robotics, and advanced air mobility, not drones alone. See the JEDI ETF guide for the full mandate and holdings tilt.
What is DRNZ, and how does it differ from these broader funds?
DRNZ is a dedicated drone and UAV fund, narrower than the broad aerospace, defense-tech, and modern-warfare funds compared on this page. See the best drone ETF guide for how it compares against JEDI and the broader funds.
Should I buy an ETF or individual defense/drone stocks instead?
That decision turns on diversification, cost, and control over which companies you own. See the drone ETF vs. stocks guide for the tradeoffs.
Is there a European equivalent of these funds for non-US investors?
Yes, but most of those funds are UCITS-domiciled and are not directly accessible through a typical US retail brokerage account. See the European defense ETF guide for the fund list and the access limits.
Was there ever a pure drone ETF that failed or shut down?
Yes. AdvisorShares liquidated its UAV ETF in 2023. See the UAV ETF page for what happened and the liquidation mechanics.
What is the trading volume/liquidity like for JEDI or SHLD compared to ITA?
Liquidity generally favors ITA over newer thematic funds like JEDI or SHLD, because ITA is older, larger, and tends to trade with tighter bid-ask spreads and higher average daily volume.
That gap can narrow as a thematic fund gathers assets, so check each fund's current average daily volume and typical spread on your broker's quote screen before placing a large order rather than assuming it trades like ITA.
Can I lose money in these funds even though defense spending keeps rising?
Yes. A fund can lose value even while sector-wide defense spending is rising, through a broad market drawdown, a valuation reset after a run-up in defense-stock prices, or a weak quarter at one of its largest concentrated holdings. Rising government spending is not the same as a guaranteed fund return; this page is informational only, not investment advice.
Does Vanguard have a defense ETF?
No. Vanguard does not currently offer a dedicated aerospace and defense ETF. Its lineup runs to broad market-cap, total-market, and sector-index funds instead, and none of them isolate defense as a standalone theme. This page compares ITA, XAR, PPA, SHLD, JEDI, and DRNZ, and none of those six funds come from Vanguard. Check Vanguard's own fund list directly before assuming otherwise, since a lineup can change.
Can investors in India, Canada, Australia, or elsewhere outside the US buy ITA, XAR, PPA, SHLD, or JEDI?
ITA, XAR, PPA, SHLD, and JEDI are exchange-traded funds (ETFs) listed on United States (US) exchanges. Buying them directly from outside the US generally requires a brokerage account with international or US-market trading access, where availability, added fees, and currency-conversion costs depend entirely on your broker.
Investors seeking a locally domiciled alternative can consult our European Defense ETF guide, though Undertakings for Collective Investment in Transferable Securities (UCITS) funds are domiciled in Europe and only resolve that issue for European buyers.
No India-, Canada-, or Australia-domiciled equivalent fund is confirmed on this page, so readers in those countries should verify US-market trading access with their own brokerage rather than assume a local fund exists.
