U.S. strikes on Iranian rocket launchers in the Strait of Hormuz, followed by retaliatory attacks on American bases in Jordan, have sharply escalated Middle East tensions.
The renewed conflict has triggered fresh investor interest in the defense sector, with analysts pointing to a sustained multi-year procurement cycle for major contractors.
Exchange-traded funds offer a diversified and strategically sound way to gain exposure to the defense industry’s potential upside without company-specific risk.
The current conflict traces back to Iran’s effective closure of the Strait of Hormuz, a chokepoint through which approximately 20% of the world’s oil once passed.
Iran’s deployment of sea mines and its demands for tanker traffic checks prompted U.S. military action, setting off what has become a prolonged and costly standoff.
Lockheed Martin (LMT), RTX Corp. (RTX), and Northrop Grumman (NOC) are among the prime contractors positioned to benefit most directly from escalating procurement demand.
Lockheed Martin saw increased demand for its Patriot missile systems, with over 800 interceptor missiles reportedly used in the conflict’s early weeks, and in July 2026 won a $59 billion Pentagon contract to triple Patriot missile production over seven years.
RTX, which produces guidance systems for Patriot missiles, secured a $22.9 billion U.S. Navy contract in mid-August to produce Tomahawk cruise missiles, of which more than 1,000 have been fired since Operation Epic Fury began in late February 2026.
Northrop Grumman’s B-2 Stealth Bomber was used to strike Iranian nuclear complexes, and the company signed two agreements worth $3 billion with the Pentagon and Lockheed Martin in August to support missile and interceptor production.
While individual defense stocks offer compelling upside, they also expose investors to elevated valuations and unexpected earnings misses that can erode gains quickly.
Defense ETFs sidestep that single-company risk by providing a basket of leading contractors and emerging defense technology firms across the entire supply chain.
With global defense spending projected to reach $2.6 trillion by the end of 2026, three ETFs stand out as particularly well-positioned for investors seeking sector exposure.
The iShares U.S. Aerospace and Defense ETF (ITA), with net assets of $13.94 billion, holds 48 U.S. aerospace and defense companies, with GE Aerospace at 21.60% weight and RTX at 17.23% weight.
ITA has gained 8.5% year to date, charges 37 basis points in fees, and holds a Zacks ETF Rank of 2, designated as a Buy.
The Invesco Aerospace and Defense ETF (PPA), valued at $8.16 billion, provides exposure to 62 companies in defense, homeland security, and aerospace, with RTX leading at 8.40% and LMT holding 6.59% weight.
PPA has also rallied 8.5% year to date, charges 58 basis points in fees, and carries the same Zacks ETF Rank of 2.
The State Street SPDR S&P Aerospace and Defense ETF (XAR), with assets under management of $5.97 billion, covers 47 aerospace and defense companies and charges just 35 basis points in annual fees.
XAR has risen 8.5% year to date and also holds a Zacks ETF Rank of 2, making it a competitive low-cost option for defense sector exposure.
All three ETFs provide meaningful weightings in LMT, RTX, and NOC, capturing upside from the largest active procurement contracts currently in play.
For investors seeking to capitalize on an extended cycle of defense spending without concentrating risk in any single contractor, these ETFs present a compelling and balanced opportunity.
