Building a megaconstellation requires an industrial base that doesn’t fully exist yet — and the RF semiconductor supply chain is the bottleneck most operators aren’t talking about publicly.
Low Earth orbit constellations are displacing legacy GEO-based inflight Wi-Fi at speed, and the competition between Starlink and Amazon Leo for airline contracts is becoming a genuine two-horse race.
The FCC’s April 2026 overhaul of satellite spectrum-sharing rules scrapped a 1990s framework that was systematically suppressing the capacity of every LEO constellation flying today.
The single biggest barrier to scaling LEO broadband has never been rockets or spectrum — it is the cost of putting a flat-panel phased-array antenna on every rooftop.
Project Kuiper enters a market where a rival already has satellites, subscribers, and a head start — so its real challenge is not technology but timing.
