Microsoft (NASDAQ:MSFT)'s $170 million Air Force cloud contract signals the massive defense modernization wave reshaping Pentagon technology buying. While Microsoft grabs headlines, the real winners are companies building hardware that protects American interests: fighter jets, missile systems, submarines, and bombers.

We ranked the top five defense and aerospace stocks based on profitability margins, operational efficiency, balance sheet strength, and positioning in the defense modernization cycle.
Boeing entered 2021 still reeling from the 737 MAX grounding, then faced COVID-19 decimating air travel demand, supply chain failures, a door plug blowout in early 2024, and a machinists' strike that produced just 57 commercial deliveries in Q4 2024. The company burned through cash, piled on debt, and suspended its dividend.
Rocket Lab's operational track record remains flawless. The company launched its 80th and 81st Electron missions in January, demonstrating reliability that wins contracts. That momentum translated into an $816 million contract from the U.S. Space Development Agency for 18 satellites, expected to add $200 million in annual revenue over four years. The company's $1 billion backlog grew 56% year over year in launch services alone.
When geopolitical tensions rise or defense budgets expand, investors often chase the sector through broad market funds. But SPDR S&P Aerospace & Defense ETF (NYSEARCA:XAR) doesn't work like most sector plays. It spreads capital equally across 41 holdings, giving smaller aerospace suppliers and emerging space companies the same weight as industry giants like Boeing ( NYSE:BA) and Lockheed Martin ( NYSE:LMT). That structural choice creates a fundamentally different risk profile than market-cap weighted alternatives.
