Lockheed derived nearly 72% of its $75 billion in 2025 sales servicing contracts from the US military, with the largest annual budget on Earth, and stands to operate the largest defense procurement program ever awarded (F-35) through the 2060s. Thus, as a bet on the defense industry, Lockheed is hard to beat. Biggest isn't always best, but Lockheed (and investors) benefit from the sheer scale of its tens of billions of dollars of contracts that provide defined decadeslong revenue and profit streams.
