The largest sustained rearm cycle since the Cold War runs through six layers: the primes that win the contracts, the missiles and munitions inventory being rebuilt, the autonomous and software stack changing the doctrine, the C4ISR network that ties it together, and the naval and ground platforms still being delivered to the fleet. Below: the public US-listed companies operating in each layer.
Primes at the apex. Vehicles and logistics at the foundation. Every US-listed public company actually operating in between.
The five firms that win the largest Department of Defense contracts and assemble most major weapon systems. Together they capture a meaningful share of total defense outlay every year and set the pace for the rest of the supply chain.
The interceptors, precision-guided munitions, and standoff weapons whose inventories were drawn down sharply by the Ukraine conflict and which are now being rebuilt under multi-year procurement contracts. The subsystem suppliers behind each round.
The smaller, software-first defense companies winning programs the primes used to dominate. Unmanned aerial systems, loitering munitions, counter-UAS, and the data and AI platforms running over the top of them.
Command, control, communications, computers, intelligence, surveillance, and reconnaissance — the digital connective tissue that turns sensors and shooters into a kill chain. Plus the federal IT services firms that build and run it.
The two US shipbuilders qualified to deliver nuclear-powered submarines and major surface combatants, plus the supplier that makes the reactor cores that power them. Long-cycle programs, decade-long backlogs, very few credible bidders.
Tactical wheeled vehicles, rotorcraft, and tracked combat platforms — the moving parts of a modern force. Smaller margins than the missile and avionics businesses, but very long replacement cycles and steady program awards.
