US Sector Analysis: Defense & Aerospace Industry
The Contract Size Is Not the Point
Governments are not asking whether to spend more on defense anymore.
That question is closed.
The one they are now asking — how fast can we — is harder to answer, and the answer lives in a place most investors have not looked.
What the Spending Calendar Actually Means
For three decades, the dominant belief across NATO was that military budgets could stay thin because the conditions justifying them had passed.
That belief is gone now, and what replaced it is not a temporary response to active conflict.
It is a formal, institutionalized calendar.
NATO raised its collective target from 2% of GDP to 5% by 2035.
Poland is already at 4.3%.
Lithuania at 4.0%.
Germany, which spent decades treating defense expenditure as politically toxic, crossed 2% for the first time since 1990 and grew its budget 24% in a single year — reaching $114 billion — without being in active combat.
Spain raised its defense budget 50% to $40.2 billion.
European NATO members collectively spent $574 billion in 2025, up 20% in real terms in one year.
Total NATO expenditure hit $1.581 trillion.
These are not emergency allocations.
A country that spent 1% of GDP for thirty years cannot reach 4% without years of contracted procurement.
The calendar does not end when a conflict does.
It ends when the procurement cycle does.
Those are different dates.
The U.S. figure — $954 billion in 2025 — appeared to dip 7.5%, which confused some observers.
The dip was accounting, not strategy.
The prior year included emergency Ukraine supplemental funding that was not renewed.
The underlying budget did not shrink.
Congress approved over $1 trillion for 2026.
Global military spending reached $2.887 trillion in 2025, its eleventh consecutive year of growth.
Where Retail Analysis Has Stopped Too Early
Most investors in this sector carry a set of beliefs that are either incomplete or demonstrably wrong.
That defense is cyclical: spending follows wars up and follows peace down.
That only active conflicts move the sector.
That revenue follows contract announcements quickly.
That margins are roughly uniform across defense companies.
That only prime contractors capture the value.
The last one is where the real analytical gap sits.
Lockheed Martin, RTX, Northrop Grumman, General Dynamics — these are the names on the headline contract.
They are widely held and widely analyzed.
The tailwind is real.
But the question investors should be asking is not whether these companies benefit.
It is whether the bottleneck that limits how much and how fast they benefit already sits somewhere else.
It does.
Where the Money Actually Stops
Conflicts in Ukraine and the Middle East depleted an estimated 30 to 50% of key missile inventories — over 1,000 Tomahawk missiles and more than 1,200 Patriot interceptors.
Tomahawk production runs at a rate that would require roughly ten years to replace what was deployed.
Patriot interceptors carry the same constraint.
Governments signed multi-year replenishment contracts.
Those contracts immediately met a ceiling: the SM-6 missile factory was already at maximum production rate as of 2025.
Additional contracts cannot accelerate delivery because the factory cannot run faster.
Above that sits the constraint most retail analysis has not engaged:
rare earth materials.
A single F-35 contains 920 pounds of rare earth elements.
THAAD interceptors depend on samarium, neodymium, and dysprosium for guidance and propulsion.
China controls 93 to 99% of global refining capacity for these materials.
In April 2025, China placed rare earth exports under formal licensing requirements, creating a documented chokepoint in the supply chain for the exact materials needed to manufacture the systems currently under procurement.
A contract does not deliver revenue if the factory cannot build what it promised.
Here is the chain that follows:
conflict depletes inventories — governments commit to replenishment — contracts go to prime contractors — prime contractors hit manufacturing ceilings — those ceilings are set by component supply, not contract size — the real constraint moves upstream to rare earth processors and specialized electronics manufacturers outside Chinese supply chains — revenue recognition lags the contract by two to ten years depending on the system.
That single reality is where most headline-level defense analysis breaks down.
What Is Still True in Three Years
Several things here are not news events.
They are multi-year capital allocation changes already in motion.
Europe's rearmament reflects a governing consensus shift that took decades to reverse.
Germany is the clearest example.
That momentum does not unwind with a change in government or a diplomatic resolution in one theater.
Taiwan-China tension is driving a parallel rearmament across the Asia-Pacific that runs independently of the European situation.
The procurement logic is equally durable.
Drone warfare has changed the economics of conflict.
Ukraine demonstrated that cheap autonomous systems can accomplish what expensive legacy platforms were designed to do.
This has not reduced demand for expensive systems.
It has added an entirely new procurement category on top of existing demand while forcing faster production timelines on systems previously built on leisurely multi-decade schedules.
Modern warfare is also becoming software-heavy.
Electronic warfare, AI targeting, satellite systems, cyber defense — these categories carry recurring revenue and higher margins than hardware.
Analysis focused only on prime contractor hardware revenues does not fully capture what the sector is becoming.
Where the Crowding Is
The prime contractor rally began after February 2022.
The Europe rearming narrative entered mainstream financial coverage at that point.
NATO's 5% target has been public since June 2025.
Large-cap names carry valuations that reflect a market which has already absorbed the headline story.
What the market has not priced:
production capacity ceilings and what they mean for revenue timing.
Investors expecting 2026 earnings spikes from recent contract announcements may see that revenue arrive in 2028 or 2029.
The backlog is real.
The timeline is long.
What the market has not priced:
the rare earth chokepoint.
China's export licensing decision received financial coverage, but its specific implications for missile and aircraft production have not yet filtered through to how individual companies are valued.
Exposure varies by system and by how aggressively each contractor has diversified supply.
That variation is not yet reflected in how the sector trades as a whole.
What the market has not priced:
the second-tier supplier layer.
When an ETF holds 35 companies and the average retail investor recognizes three names, the remaining holdings represent companies that benefit from the same spending trajectory without carrying the same valuation premiums.
The crowding is concentrated at the top. So is the analysis. So is the pricing.
Defense software and intelligence names — Palantir, CACI International, Booz Allen Hamilton — operate at the intersection of defense and AI-driven systems work, growing faster than legacy hardware procurement and carrying more durable margin profiles.
MP Materials and Lynas operate in rare earth production outside Chinese control.
They are not defense companies in the traditional sense.
But China's April 2025 export licensing decision connects them directly to missile and aircraft manufacturing timelines.
The companies that benefit from a chokepoint the prime contractors cannot resolve internally are a different kind of defense play.
What to Hold
Margin and cash flow mechanics differ enough between missile systems, aircraft, and shipbuilding that generalizations flatten important distinctions.
Company-level financial work is required before any position.
The rare earth dependency is verifiable in outline.
Specific financial exposure by contractor requires procurement data that is not fully public and varies by system.
Everything in the spending figures is sourced and verifiable.
Claims about what is or is not priced into current valuations are interpretation, not data.
The Real Shift
For thirty years, defense analysis asked who won the contract.
The next decade belongs to whoever controls what the winner cannot build without.
