We read the replacement question as an industrial problem wearing a legal costume. The challengers, Skydio, Parrot, Teal and the European entrants, are credible and improving, but they compete against a company that ships millions of aircraft a year, iterates annually, and controls the price-performance frontier in thermal imaging, transmission and ecosystem depth. The binding constraint is not airframe design but the component chain: cells, motors, magnets and sensors that even compliant Western drones still source from China. Our base case is that 2027 dependence deepens rather than breaks, because dependence is an equilibrium produced by cost and volume, and only a sustained subsidy-and-onshoring program, not another listing, changes equilibria.
The question is worth posing precisely, because in 2027 it may stop being hypothetical. Suppose the restriction machinery now in motion, FCC authorizations, procurement bans, component rules, actually excluded DJI from Western fleets rather than merely taxing it. The question then is whether Western industry could replace the workhorse. The honest answer splits into two scenarios, and any desk that gives only one is selling something. Every serious Western defense ministry now runs some version of this calculation, usually in classified annexes that leak only as procurement behavior. What follows is the case for each side, with the arithmetic that separates them.
Start with the challengers, because they are real. Skydio's X10, at roughly $15,000 and up, is a genuinely capable American aircraft with class-leading obstacle avoidance. Parrot's ANAFI USA, near $7,000, offers a compliant thermal quad from a European vendor. Teal, under Red Cat, and Performance Drone Works with the C100 build for the American defense buyer, and Anduril covers the heavier autonomous end. Europe adds Quantum Systems, Delair, Acecore and others, Auterion supplies the software layer for much of the Western fleet, and a long tail of venture-backed firms fills the space between presentation and production. Every one of these firms is better in 2026 than it was in 2023. None of them, individually or together, ships within two orders of magnitude of DJI's volume, and volume is where the workhorse problem lives.
The price-performance gap remains the immediate obstacle. A Mavic-class thermal quadcopter lists around $4,700; the compliant equivalents with comparable sensors run three to five times that, with longer lead times. The gaps are not only in price. Transmission range and robustness, thermal image quality, battery ecosystem, and the depth of the accessories and software market all favor the incumbent, because all of them compound with scale. DJI's transmission systems, iterated through the O3 and O4 generations, remain the benchmark Western links are measured against, and its yield on folded airframes and three-axis gimbals is a decade of process learning that cannot be bought off the shelf. Skydio's early deliveries to Ukraine reportedly struggled against Russian jamming before software revisions improved matters, an episode that showed both sides of the ledger: the deficit was real, and so was the speed of the fix.

Suppose enforcement actually excluded DJI in 2027. The honest answer has two scenarios: a partial, expensive replacement that succeeds at the high end, or a dependence that quietly deepens.
