Lockheed Martin Corporation

The F-35 Lightning II is the most expensive weapons program in US history, with a total program cost exceeding $1.7 trillion when lifetime sustainment is included. For LMT shareholders, that number is an advantage rather than a liability: the aircraft requires continuous software upgrades, weapons system integration, and component replacement over a 30-40 year operational lifespan. Every country that buys an F-35 also enters a multi-decade sustainment relationship with Lockheed Martin, creating aftermarket revenue that is more predictable than new production contracts. By 2026, over 1,000 F-35s were delivered globally across 16 nations, with hundreds more on order.

The classified programs within LMT's Aeronautics and Space segments provide an additional earnings buffer that investors can model only partially through public disclosures. Programs like the Next Generation Air Dominance (NGAD) and classified satellite constellations generate cost-plus revenue with guaranteed margins, which stabilizes earnings against any slowdown in F-35 production rates. This combination — a high-volume legacy program with decades of sustainment ahead and classified growth programs with cost-plus margins — creates the earnings quality that institutional investors ascribe a premium multiple to, even as cyclical investors argue LMT is expensive relative to its near-term earnings growth rate.

Defense stocks move on two types of catalysts: budget events (Congressional appropriations, Pentagon budget requests, NATO summit commitments) and geopolitical shocks (conflict escalation, new threat environments requiring rapid procurement). LMT typically rallies on geopolitical shocks within hours of the news event, but the more durable move comes when the initial shock translates into congressional supplemental spending bills or allied procurement announcements — that is when the order backlog actually grows and earnings estimates get revised upward. Traders who chase the immediate news pop often buy the top; those who wait for the backlog confirmation typically enter closer to the bottom of the post-spike consolidation.

LMT's dividend history and share buyback program make it a holding that institutional investors are reluctant to sell during broad market corrections, which creates natural support levels during drawdowns. The stock tends to be range-bound in periods of geopolitical calm and sustained uptrends when threat environments deteriorate. Relative to RTX, LMT is the pure-play defense bet with more fixed-price contract risk but also more upside leverage to a defense spending surge, while RTX's commercial aerospace exposure provides a smoother earnings profile.
