The Global Defense Supply Chain
From specialty materials to prime platforms: a complete supply-chain map for the rearmament cycle
The Iran war, European rearmament and rising Asia-Pacific defense budgets have pushed global military spending into a multi-year expansion. This topic breaks the defense supply chain into 8 layers and 54 listed companies — advanced materials → critical components → engines → mission electronics → prime platforms → uncrewed systems → services and defense space — with 53 of them already covered in depth by our research reports, each annotated with its role and weight in the chain.
Advanced Defense Materials
Titanium alloys, superalloys, carbon-fiber composites and beryllium form the physical foundation of the entire chain — airframe weight savings, engine heat tolerance and missile seekers all start here, with high qualification barriers and short supplier lists.
Leader in titanium and nickel-based superalloys, supplying specialty materials for aero engines and airframe structures, driven by both defense and commercial engine demand.
Specialty alloys and powder-metallurgy materials producer; superalloy bar and wire feed aero-engine parts and aerospace fasteners.
Primary supplier of aerospace-grade carbon fiber and honeycomb composites, serving weight-reduction needs on the F-35 and Airbus and Boeing widebodies.
Scarce supplier of beryllium and beryllium composites, used in missile seekers, satellite structures and nuclear applications.
China's core supplier of military-grade titanium alloy bar and wire and low-temperature superconducting wire — a key link in localizing structural materials for new-generation fighters.
Korean defense materials and components supplier, scaling with the export cycle of Korean platforms and munitions.
Critical Components & Subsystems
Bearings, fasteners, actuation, hydraulics, connectors and proprietary aftermarket parts: low unit prices, sole-source part numbers and exclusive certifications make this the best cash-flow segment of the defense chain.
Platform conglomerate of proprietary aerospace components; sole-source part numbers plus aftermarket pricing power, straddling defense and commercial.
FAA-approved replacement parts (PMA) and defense electronics group, an acquisition-driven portfolio of niche components.

Maker of missile and launch-vehicle structures, separation systems and thermal protection — a direct beneficiary of hypersonic and interceptor volume growth.
Engines & Propulsion
Military aero propulsion is down to a handful of players worldwide and certification cycles run in decades; once an engine is selected, propulsion and aftermarket lock in for the platform's entire life.
The world's leading military and commercial aero-engine maker — F110, T700 and other military powerplants plus a decades-long aftermarket tail.
Supplier of fighter and naval propulsion, and of nuclear reactors for UK and AUKUS submarines — the bedrock of British defense propulsion.
CFM joint-venture partner and leader in helicopter turboshafts, alongside military optronics and landing-gear systems.
Defense Electronics · Radar · C4ISR
Modern war is first a contest of sensing and command: radar, electronic warfare, tactical communications and mission computing decide platform lethality — and this is the highest-beta segment of European rearmament.
Tactical communications, electronic warfare and space payloads group, positioned as America's 'sixth prime'.
Europe's leader in radar, air-defense command systems and military avionics — the hub of French defense electronics.
Italian defense group spanning helicopters and defense electronics, and a core participant in the GCAP next-generation fighter.

Infrared imaging (FLIR), uncrewed-system payloads and defense instruments group, with sensors across land, sea, air and space.
Military embedded computing and RF subsystems maker, benefiting from re-shoring of the US defense electronics supply chain.
Small-cap supplier of military and space-grade precision timing devices — the timing link in satellites and missile guidance.
Norwegian defense group: NSM/JSM anti-ship missiles and remote weapon stations exported worldwide, with air defense and maritime systems as twin engines.
Germany's leader in military radar and electro-optical sensors, a direct beneficiary of the sensor layer of European rearmament.
Primes & Complete Platforms
The integrators of fighters, warships, armor and missiles, facing defense ministries directly; this cycle's keywords are capacity, munitions and exports — order books at European and Asia-Pacific primes are rewriting their histories.

We converted the cross-references inside 1,068 research reports into a directed network: 680 reports naming 1,623 distinct companies 4,010 times across 183 industries. Four gravity centers — NVIDIA (56 mentions), Microsoft, Alphabet and Amazon — anchor roughly 30 industries each, and the highest-scoring growth stories lean on Microsoft even more than on NVIDIA. Exactly four companies are named four or more times without a report of their own — Nexans, NKT, Dentsply Sirona and Hensoldt — and that gap list now goes straight into our production queue.
First edition of our quarterly Growth Score Index, built from 897 fully scored companies in the Zen Horizon research library. The median score is 43/100 and exactly one company clears 65, because the test is a credible ten-year 5x path, and durable quality turns out to be far more common than durable hypergrowth. Twelve names combine a top-decile score with a price below our fair-value band.
When a big company joins the S&P 500, index funds are genuinely forced by the rules to buy it. The "inclusion premium" that used to come with that, though, has all but vanished over the past two decades. Drawing on the membership rules of the three major index families, the mechanical buying from $20 trillion in passive money, and first-hand academic evidence on the "disappearing index effect," this piece asks what a spot in an index is really worth. The verdict: passive demand equals roughly 7–8% of a new member's float and is genuinely measurable, but the excess return from announcement to effective date has fallen from 7.4% in the 1990s to 0.3% over the last decade. SpaceX cannot get into the S&P 500 and is about 15 trading days from the Nasdaq-100; its rock-bottom 4.25% float is the real variable.
Three years into the AI rally, leadership has rotated from compute chips to power, to memory, and now toward application software, and the question most people get stuck on is simply "where are we now." This piece reconstructs the rotation logic from verifiable data, the annual leaders, the capex trajectory, and the bottleneck of the moment. Money follows the tightest chokepoint in the supply chain, and whoever holds the chokepoint leads. Our read, June 2026 sits in the overlap between the late-middle of the infrastructure rally and the early innings of applications taking the baton. Memory and power are still the tightest bottlenecks, software applications are up just 17.6% over three years, and the application rally has not really begun.
