Defense remains one of the clearest structural themes in the market heading into May 2026. What began as a cyclical response to geopolitical shocks increasingly looks like a multi-year rearmament cycle, supported by NATO spending targets, inventory replenishment, and modernization plans that extend well beyond a single budget year. That backdrop matters for investors because it can create unusually durable demand visibility for the right contractors, especially those tied to programs that are hard to defer once procurement priorities are set.
The most attractive pockets of the theme are still the ones closest to urgent capability gaps: munitions and ammunition, missile and air-defense systems, military vehicles and land systems, defense electronics and sensors, and select aerospace primes with large installed bases and recurring sustainment revenue. The Pentagon’s March 25, 2026 framework agreements with BAE Systems, Lockheed Martin, and Honeywell to expand munitions production reinforce the idea that industrial capacity itself has become strategic, and that replenishment demand is still accelerating.
Still, this is no longer a theme where every defense name should be treated equally. Investors have become more selective, rewarding visible order books, consistent execution, and reasonable valuations while punishing margin pressure and earnings volatility. In that spirit, this list is ranked in countdown order from #10 to #1, with the strongest overall pick revealed at the end based on composite quality grade.
For this screen, we focused on U.S.-listed companies with market capitalizations above $500 million that have meaningful exposure to defense, aerospace, military systems, or government mission support. We then ranked the final list primarily by composite quality grade, while also weighing profitability, growth, earnings execution, and analyst sentiment to separate stronger all-around operators from more speculative names. This is a countdown, so the list starts at #10 and works toward the best pick at #1.
What they do. The company designs and supports robotic systems for government and business customers, with operations spanning Autonomous Systems and Space, Cyber and Directed Energy. Its portfolio includes uncrewed aircraft systems, counter-UAS, precision strike loitering munitions, electronic warfare systems, unmanned maritime and ground systems, and a range of space and cyber technologies.
Why it fits. AeroVironment sits in one of the most relevant corners of the defense theme: low-cost autonomous systems, counter-drone tools, and precision strike. Those categories line up directly with rising demand for loitering munitions, battlefield intelligence, electronic warfare, and distributed systems that can be fielded faster than traditional platforms.
Numbers that matter. Revenue is $1.61 billion, and year-over-year revenue growth is 143.4%, with earnings growth up 175.7%, so the top-line expansion story is real. But profitability is currently weak: gross margin is 25.0%, operating margin is -5.11%, net margin is -13.93%, ROE is -8.74%, and ROA is -1.26%. The company is also not currently profitable on a trailing basis, while forward P/E is 45.45, which helps explain the lower quality grade despite strong growth.
Recent momentum. Execution has been uneven. AeroVironment has beaten estimates in just 2 of its last 8 reported quarters, including misses of 11.7% on March 10, 2026 and 45.0% on December 3, 2025. Analysts still lean constructive, with a 4.5714 consensus and an average target of $309.8771, but the split is narrow at 1 Buy and 1 Hold, which suggests conviction is limited.
What they do. The company provides technology, hardware, systems, and software for defense and national security customers through Kratos Government Solutions and Unmanned Systems. Its offerings include virtualized satellite ground systems, jet-powered drones, hypersonic vehicles and rocket systems, propulsion for missiles and loitering munitions, microwave electronics for radar and missile defense, and counter-UAS and directed energy systems.
Why it fits. Kratos is tightly aligned with several of the market’s preferred defense sub-segments, including unmanned systems, missile-related electronics, hypersonics, and space infrastructure. That makes it a credible way to play the modernization side of defense spending rather than just traditional platform procurement.
Numbers that matter. Revenue stands at $1.42 billion, with year-over-year revenue growth of 22.6% and earnings growth of 130.6%, both strong for a mid-cap defense name. Profitability, however, remains thin: gross margin is 22.9%, operating margin is 1.78%, net margin is 2.08%, ROE is 1.23%, and ROA is 0.57%. Valuation is the main sticking point, with trailing P/E at 318.94 and forward P/E at 135.14, which is rich relative to current margins.
Recent momentum. Kratos has been one of the cleaner earnings executors on the list, beating estimates in 8 of the last 8 quarters. Most recently, it beat by 2.4% on May 13, 2026 after a 9.1% beat in February. Analysts remain positive overall, with a 4.1667 consensus, an average target of $111.95, and a breakdown of 2 Buys and 4 Holds.
What they do. The company supplies engineered products and services across Aerospace & Industrial, Defense Electronics, and Naval & Power. Its defense-relevant portfolio includes embedded computing, tactical communications, avionics, flight-test equipment, weapons handling systems, naval propulsion components, arresting systems, and ship repair and maintenance for the U.S. Navy.
Why it fits. Curtiss-Wright is a quieter but important enabler of the defense buildout because it sells the electronics, instrumentation, naval systems, and sustainment capabilities that sit inside larger programs. In a market rewarding installed-base exposure and recurring aftermarket revenue, that mix is especially attractive.
Numbers that matter. Revenue is $3.61 billion, with year-over-year revenue growth of 13.4% and earnings growth of 29.1%. Profitability is strong across the board: gross margin is 37.2%, operating margin is 17.56%, net margin is 14.17%, ROE is 19.69%, and ROA is 8.58%. Valuation is less forgiving, with trailing P/E at 52.08 and forward P/E at 28.41, so investors are paying up for quality and consistency.
Recent momentum. Momentum has been excellent. Curtiss-Wright has beaten estimates in 8 straight quarters, including a 17.2% beat on May 6, 2026 and an 18.0% beat in May 2025. Analysts are constructive but not euphoric, with a 4.2222 consensus, an average target of $756.5714, and 1 Buy versus 3 Holds.

What they do. The company designs, builds, overhauls, and repairs military ships through its Ingalls, Newport News, and Mission Technologies segments. It is deeply tied to U.S. naval power, spanning aircraft carriers, submarines, amphibious ships, surface combatants, and a growing mission systems business that includes C5ISR, AI, cyber, electronic warfare, and autonomous systems.
Why it fits. Huntington Ingalls is one of the clearest ways to gain exposure to fleet replacement, naval maintenance, and long-cycle shipbuilding budgets. In a world of sustained maritime competition and submarine demand, its role in carriers, submarines, and sustainment gives it unusually high strategic relevance.
Numbers that matter. Revenue is $12.85 billion, and year-over-year revenue growth is 13.4%. Margins are more modest than many electronics-heavy peers, with gross margin at 12.4%, operating margin at 6.55%, and net margin at 4.71%, but returns are still respectable at 12.20% ROE and 4.10% ROA. Valuation looks more grounded, with trailing P/E at 21.41 and forward P/E at 18.02.
Recent momentum. Huntington Ingalls has beaten estimates in 7 of its last 8 quarters, including a 2.2% beat on April 30, 2026 and a 5.5% beat on February 5, 2026. Analyst sentiment is more cautious than bullish, with a 3.3846 consensus, an average target of $388.2727, and a breakdown of 2 Buys, 8 Holds, and 1 Sell.
What they do. The company provides mission-critical systems through Space & Mission Systems, Communications & Spectrum Dominance, and Missile Solutions. Its portfolio spans missile warning and defense, tactical radios, satellite terminals, battlefield systems, night-vision products, propulsion technologies, and advanced missile and hypersonic capabilities.
Why it fits. L3Harris checks several of the highest-priority boxes in the current defense cycle: communications, spectrum dominance, missile solutions, sensors, and space-based mission systems. Those are exactly the kinds of enabling technologies that benefit when militaries invest in survivability, networking, and layered air and missile defense.
Numbers that matter. Revenue is $12.86 billion, with year-over-year revenue growth of 190.0%, though earnings growth is down 6.1%. Profitability remains solid, with gross margin at 30.4%, operating margin at 9.73%, net margin at 10.37%, ROE at 8.19%, and ROA at 4.24%. Valuation is not cheap but also not extreme for a major defense electronics franchise, with trailing P/E at 33.79 and forward P/E at 26.04.
Recent momentum. Earnings execution has been very steady, with 8 beats in the last 8 quarters. The latest report on April 23, 2026 beat estimates by 6.9%, following a 3.2% beat in January. Analysts are broadly constructive, with a 4.32 consensus, an average target of $381.9474, and 5 Buys against 6 Holds.
What they do. The company operates across Aeronautics Systems, Defense Systems, Mission Systems, and Space Systems. That gives it exposure to strategic aircraft, unmanned systems, tactical weapons, missile defense, ammunition and precision munitions, radar and electronic warfare, satellites, interceptors, and launch-related propulsion.
Why it fits. Northrop Grumman is one of the most complete plays on the structural rearmament story because it touches nearly every priority area: long-range strike, missile defense, munitions, sensors, and space. Its mix is especially relevant in an environment where strategic deterrence and air-defense capacity are both being funded at scale.
Numbers that matter. Revenue is $42.37 billion, with year-over-year revenue growth of 4.4% and earnings growth of 84.9%. Profitability is strong, with gross margin at 20.5%, operating margin at 11.69%, net margin at 10.8%, ROE at 28.51%, and ROA at 7.36%. Valuation is relatively reasonable for a prime contractor of this quality, with trailing P/E at 17.24 and forward P/E at 19.61.
Recent momentum. Northrop has beaten estimates in 6 of its last 7 completed quarters. Most recently, it posted a 1.3% beat on April 21, 2026 after a 3.9% beat in January, though investors will remember the 47.0% miss in April 2025. Analysts still lean positive, with a 3.96 consensus, an average target of $701.6354, and 4 Buys versus 11 Holds.
What they do. The company is one of the largest defense primes in the world, operating across Aeronautics, Missiles and Fire Control, Rotary and Mission Systems, and Space. Its portfolio includes combat aircraft, air and missile defense systems, tactical missiles, precision strike systems, helicopters, radar and laser systems, cyber solutions, satellites, and strategic defense programs.
Why it fits. Lockheed Martin is central to the current defense thesis because it sits directly in missile defense, precision strike, combat aviation, and space. The Pentagon’s March 2026 framework agreement to expand munitions production with Lockheed Martin also reinforces its relevance to the replenishment and industrial-capacity side of the theme.
Numbers that matter. Revenue is $75.11 billion, but growth has been muted, with year-over-year revenue growth of just 0.3% and earnings growth down 11.5%. Profitability is still solid, with operating margin at 11.0%, net margin at 6.38%, ROE at 67.64%, and ROA at 7.23%. Valuation looks more attractive on forward earnings than trailing results, with trailing P/E at 25.60 versus forward P/E at 16.81.
Recent momentum. Recent earnings have been mixed. Lockheed has beaten estimates in only 3 of its last 7 completed quarters, including misses of 4.3% in April 2026 and 2.7% in January 2026, with larger misses in July 2025 and January 2025. Analyst sentiment reflects that caution, with a 3.7083 consensus, an average target of $637.6, and a breakdown of 4 Buys, 12 Holds, and 1 Sell.
