Thermal camera prices jump in steps because ECCN 6A003.b.4.b splits control on 111,000 focal-plane elements: 384×288 clears it by 408 pixels, 640×512 is three times over, nothing common sits between, and FLIR prices the Boson 640 at 2.04–2.31× the 320. The Note 3.b carve-out then limits not resolution but focal length — you may have a thermal camera, just not a telephoto one.
The public evidence of a production ramp isn't in the factory but in the government e-procurement system: the fire service's 88 thermal drone sets were priced centrally, six fire departments' first tenders drew no qualifying bidder, all seven awards I pulled equal the budget to the dollar, and the bidder pool is about six firms. A control group added afterwards — aerial ladder trucks, at 0.54 failed-to-awarded versus the drones' 0.33 — refutes this post's original first conclusion: failed tenders are the norm in Taiwanese fire-service procurement.
Hover power scales with takeoff weight to the 1.5 power while battery energy scales linearly, and that one exponent gap makes added battery hit diminishing returns fast — the optimum battery fraction solves to two-thirds of takeoff weight, independent of rotor diameter, rotor count, efficiency and energy density. What actually caps endurance is payload, not the regulatory weight thresholds: 60 minutes needs a 314 Wh/kg cell, and the best high-rate cell today is 242 Wh/kg.
Measuring the drone sector against supply chain chokepoint / structural demand / high switching cost / long-term institutional holding: Taiwan sits at the most substitutable layer, 80% of demand comes from public budgets rather than end-user behavior, and only the certification-driven switching cost genuinely holds. The Army's NT$988M counter-drone contract — failed three times, terminated in full, NT$98.78M performance bond forfeited — is the most expensive lesson in why winning a bid is not revenue.
Hardware runs 35–55% gross margin under permanent DJI price pressure; autonomy software and DaaS subscriptions run 60–80% and recur. Skydio's software subscriptions were already ~30% of revenue in 2023 at a 38% blended margin; India's Garuda had DaaS at 62% of FY24 revenue with a 351-day cash conversion cycle against a defense-heavy peer's 597. Taiwan is almost entirely concentrated in the lowest-margin, most substitutable cell.
The 2016 consumer drone bubble left specific wreckage: 3D Robotics stopped making hardware, GoPro recalled all 2,500 Karma units six weeks after launch and cut 15% of staff, Parrot cut 35% of its drone workforce, and Lily Robotics collapsed after taking $34M in pre-orders. In 2023 even Skydio — $570M raised — exited consumer, and three years later it is valued at $4.4 billion. This wave runs on a completely different engine, but three things are exactly the same.
The global drone market is roughly US$69B in 2026 (IDTechEx). China holds about 80% of it (CSIS) and DJI over 70% of multi-rotor. The FCC put every foreign-made drone on its Covered List in December 2025; Taiwan's drone output jumped from NT$5.0B to NT$12.9B in one year, and Q1 2026 exports already beat all of 2025. This piece breaks down the five-layer supply chain, the four demand blocks, and the two ceilings holding back scale.
Of the 267 companies the Ministry of Economic Affairs counted, 164 are in northern Taiwan. But geography is not division of labor — Thunder Tiger's published bill of materials shows motors, batteries, frames, and propellers sourced locally, while flight control, comms/GPS, and camera modules go to US, European, and Japanese partners. Exports were only 23% of 2025's NT$12.9B output, and 88.1% of export value sits in the 2–7 kg weight band per Ministry of Finance statistics.
