Defense stock searches have grown 6x in the past year, signaling where retail capital is hunting.
Defense stocks are publicly traded companies with material revenue from military, defense, or national security products and services. The category includes the prime contractors (Lockheed Martin, RTX, Northrop Grumman, General Dynamics, L3Harris, Boeing through its defense segment), drone and unmanned systems specialists (AeroVironment, Kratos), missile and electronics specialists, defense IT and cyber (Booz Allen Hamilton, Leidos), and emerging defense tech.
The category overlaps with aerospace (Boeing, Textron, BWXT) and space (covered separately) but typically excludes pure commercial aerospace and space.
There are five main entry points.
Prime defense contractors are the largest and most stable defense names. Lockheed Martin (LMT) is the largest pure defense prime, with major programs including F-35, missile defense, and space systems. RTX (RTX) covers Pratt and Whitney engines, missiles, and air defense. Northrop Grumman (NOC) leads in nuclear modernization and the B-21 bomber program. General Dynamics (GD) covers combat vehicles, submarines, and defense IT. L3Harris (LHX) covers defense communications and electronics.
Drone and unmanned systems has been the fastest-growing sub-sector. AeroVironment (AVAV) leads US tactical unmanned systems. Kratos Defense (KTOS) supplies unmanned aircraft and missile defense systems. Red Cat Holdings (RCAT) is a smaller drone specialist.
Defense IT, cyber, and services include Booz Allen Hamilton (BAH), Leidos (LDOS), CACI International (CACI), and Science Applications International (SAIC). These have less binary exposure than equipment makers.
Emerging defense tech includes companies developing AI, autonomy, and space-based defense systems. Many are still pre-revenue or recently public.
Defense ETFs include the iShares US Aerospace and Defense ETF (ITA, the largest defense ETF), the SPDR S&P Aerospace and Defense ETF (XAR, equal-weighted, more small-cap exposure), the Invesco Aerospace and Defense ETF (PPA), and the Global X Defense Tech ETF (SHLD, focused on emerging defense technology).
Government contracts dominate revenue. The Department of Defense is the largest customer for nearly every major defense stock. Budget changes and procurement decisions affect them directly.
Election cycles matter. US administration changes can accelerate or slow procurement, especially for new programs.
International sales matter. Defense exports to NATO allies and others provide revenue diversification.
Production scaling is the constraint. Many primes have order backlogs measured in years. Production capacity expansions take time, which affects revenue conversion.
Prime Contractors: LMT, RTX, NOC, GD, LHX, BA (defense segment).
Drone and Unmanned Systems: AVAV, KTOS, RCAT.
Missile and Air Defense: LMT, RTX, NOC, AJRD (acquired).
Defense IT and Services: BAH, LDOS, CACI, SAIC, KBR.
Defense Technology and Emerging: PLTR (defense AI), ANDURIL (private), space defense names.
Defense ETFs: ITA, XAR, PPA, SHLD.
US defense spending continues to grow, with FY2026 enacted spending exceeding $890 billion. Munition production scaling remains a multi-year priority, with backlogs for missiles and key munition stocks at multi-year highs.
NATO defense spending has accelerated meaningfully since 2022. Most members have committed to the 2% of GDP minimum, and several (Poland, the Baltics, Greece) now exceed 3%.
Asia-Pacific tensions have driven Japan, South Korea, Australia, and Taiwan to increase defense spending substantially.
Drone and AI-enabled systems are the largest growth segments within defense, driven by lessons from Ukraine and accelerated US Department of Defense focus on autonomous systems.
What are the best defense stocks to buy?
The most-held US defense stocks among institutional investors are Lockheed Martin, RTX, Northrop Grumman, General Dynamics, and L3Harris.

What is the largest defense stock?
By market capitalization and defense revenue, RTX and Lockheed Martin are the two largest US defense primes. Both consistently report annual revenue above $60 billion, with most of it from defense.
What is a defense ETF?
A defense ETF is an exchange-traded fund focused on aerospace and defense stocks. The largest defense ETFs are the iShares US Aerospace and Defense ETF (ITA), the SPDR S&P Aerospace and Defense ETF (XAR), and the Invesco Aerospace and Defense ETF (PPA). The Global X Defense Tech ETF (SHLD) targets emerging defense technology specifically.
What stocks benefit from war?
Defense contractors typically benefit most from prolonged conflict, as governments accelerate procurement and replenish munitions. The most direct exposure is Lockheed Martin, RTX, Northrop Grumman, and General Dynamics. Drone makers like AeroVironment have seen accelerated growth from the Ukraine conflict specifically.
What are drone stocks?
Drone stocks are companies that manufacture or supply unmanned aerial systems and components. The largest publicly traded US drone-focused stocks include AeroVironment (AVAV), Kratos Defense (KTOS), and Red Cat Holdings (RCAT). Major defense primes also have significant drone programs.
Defense stocks are in the early years of the largest sustained defense build in 40 years. Coverage focuses on US-listed equities with real defense revenue, not pure speculation.
