The drone war will be won by whoever owns the chokepoints.
Magnets, batteries, seekers, jammers, silicon. Drone Bottlenecks maps the physical supply chain behind every drone and counter-drone system — and the listed companies that own each choke. Own the strait, not the tanker.

The chokepoints
I
Rare-earth magnets & motors
NdFeB magnets are a China-controlled chokepoint sitting inside every drone motor.
MP · USAR · LYSCF · UUUU · UMAC · AREC · VULCAN
II
Batteries & energy density
Flight time is payload math; silicon-anode cells and non-Chinese LiPo supply are the unlock.
AMPX · ENVX · ENS · ULBI · LYTEN · NANOTECH
III
EO/IR & thermal sensors
Every ISR payload and interceptor seeker needs germanium optics and thermal cores.
TDY · DRS · LPTH · LHX · ESLT · MRCY · UMICY
IV
RF, EW & detection
The counter-UAS kill chain starts with detect/track; jamming is the cheap kill.
DRSHF · AVAV · KTOS · LHX · CACI · ANDURIL · EPIRUS
V
Autonomy compute
GPS-denied autonomy needs edge AI silicon that fits drone power budgets.
NVDA · AMBA · QCOM · LSCC · LTRX · HAILO · SHIELDAI
VI
Airframes & primes
The visible layer: platform makers and program-of-record winners.
AVAV · KTOS · RCAT · ONDS · DPRO · ANDURIL · SHIELDAI
VII
Comms, datalinks & PNT
Anti-jam GPS and resilient datalinks decide whether anything works in a contested environment.
IRDM · MSI · BAESY · LHX · MOB · NN · DOODLELABS
VIII
NDAA-compliant supply chain
The anti-DJI choke: Blue UAS framework components and the reshoring of small-drone parts.
AVAV · MOB · NEROS · ONDS · RCAT · SHIELDAI · UMAC
IX
Interceptors & effectors
The $1k-drone-vs-$1M-missile cost asymmetry forces new kinetic and directed-energy effectors.
RTX · AVAV · KTOS · DRSHF · ONDS · ANDURIL · EPIRUS
X
Private giants & exposure vehicles
Anduril, Shield AI, Skydio, Epirus, Neros — the names that define the sector without tickers, and the listed funds that hold them.

Latest brief · 2026-09-11
AeroVironment extended its post-earnings run on a record backlog while the rare-earth magnet chokepoint sold off on U.S.–China thaw hopes.
AeroVironment (AVAV) added 4.5% to $147.07, the drone basket's clear leader and one of the few large gains on a broadly red tape. The move extended the reaction to its latest quarterly report — record quarterly revenue of $480.5 million, a book-to-bill of 1.4, and a record $1.5 billion funded backlog, up 37% year over year, alongside a first international order (~$50 million) for its LOCUST counter-drone laser. On this vertical AVAV sits on the loitering-munition and counter-UAS chokepoint — the deployable-airframe-plus-effects layer — and a backlog growing faster than revenue is exactly the demand signal that layer trades on. It rose against the grain: the S&P 500 fell 0.58% and the Nasdaq 0.65% for a fourth straight down day, with WTI crude above $100 and Fed funds futures pricing roughly a 73% chance of a quarter-point rate hike next week.
The offset landed on the materials chokepoint. Energy Fuels (UUUU) fell 6.3% to $13.63, the basket's steepest decliner, part of a sector-wide reset in the rare-earth complex: MP Materials (MP) dropped 5.5% to $51.32 and USA Rare Earth (USAR) fell 6.0% to $16.04, with American Resources (AREC) down 5.2%. The catalyst was diplomatic, not operational — rare-earth names repriced lower on renewed U.S.–China thaw hopes, which deflate the scarcity premium built into the NdFeB magnet supply that every drone motor and actuator depends on. Nothing broke in the mines; the market simply paid less for the strait.
The rest of the tape split cleanly along the defense-versus-rate line. The primes and integrators held: CACI International (CACI) rose 2.8% to $624.01, Elbit Systems (ESLT) gained 1.3%, BAE Systems' ADR (BAESY) added 1.1%, and Motorola Solutions (MSI) rose 0.9% — the funded, backlog-heavy end of the vertical that a higher-oil, higher-rate session rewards. The speculative small-caps did not: Draganfly (DPRO) fell 5.2% to $5.47. The read is a rotation within the vertical toward names whose revenue is already contracted and away from those still pricing a supply-chain premium.
The catalyst path keeps the magnet chokepoint in focus. China's one-year suspension of its October 2025 rare-earth export controls expires November 10, and the parallel suspension of the gallium/germanium/antimony ban lapses November 27 — the dates that decide whether today's thaw trade holds. Nearer term, the FAA's Part 108 BVLOS final rule remains overdue against its H2 2026 target, the USAF's CCA Increment 1 competitive production decision is targeted by late September, and the AUSA Annual Meeting (Oct 12–14, Washington) is where the next tranche of program signals gets set.
