The F-35 program: why a single aircraft creates decades of earnings visibility
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.
- Watch F-35 delivery counts (quarterly) and international order announcements as leading indicators of future sustainment revenue.
- Classified program revenue as a percentage of total sales shows whether LMT's highest-margin business is growing.
- NATO defense spending pledges (2% GDP target now moving toward 3-5% in some countries) are the macro driver for international LMT orders.
