What Starlink Gen4 Will Probably Look Like — Reading the FCC Filings
SpaceX has filed for next-gen satellite hardware, V3 phased arrays, and a 'compact V4 user terminal' through 2025-2026. Here's what the public record actually says about the dish that comes after Gen3.
Speculation
Every few months a leaked render or supposed insider post predicts what the next Starlink dish will look like. Most of these are nonsense. But the FCC filings from SpaceX over the past 18 months are public, specific, and revealing — and they suggest a Gen4 product launch in late 2026 or early 2027 with three meaningful changes from Gen3.
What follows is built entirely from the public filing record. No insiders, no leaks, no Twitter screenshots.
What the FCC actually says
SpaceX's June 2025 amendment to its Gen2 LEO constellation authorisation filed for next-generation user terminal certification under the model code "UT-V4-CMP" (compact V4). The technical exhibit lists a phased-array aperture roughly 60% the size of the Gen3 dish, with double the element count and 2.3× the peak EIRP. Translation: a smaller, faster dish.
Separately, the November 2025 satellite filing for V3-class satellites (the Starship-launched generation) describes inter-satellite optical links at 200 Gbps — 4× the V2 Mini links — and ground-link bands that include the new 47.2-50.2 GHz V-band allocation.
Three meaningful changes I expect from Gen4
1. Smaller, lighter, more thermally efficient. If the FCC filing data is accurate, Gen4 will be roughly Mini-sized but with Gen3-class throughput. The form factor matters — a sub-2-kg dish with permanent install rating opens up scooter, light-aircraft, and small-vessel use cases that Gen3 currently rules out.
2. V-band ground links. Doubles or triples backhaul capacity per satellite. End-user-visible benefit: less throughput throttling during peak hours, particularly in already-saturated US markets like Texas and Florida.
3. Native Direct-to-Cell relay. The user terminal filing references "NTN coexistence" with 3GPP Release 17 satellite signaling. In plain English: a Gen4 dish may be able to act as a private 5G femtocell, providing local cellular coverage to phones near the dish. That would be a genuinely new product category.
What's almost certainly NOT happening
A flat-panel rectangular wall-mount dish. The viral renders showing a TV-thin Starlink panel are fan art. Phased-array physics requires a minimum aperture for reasonable gain at Ku-band; you cannot get below the current Mini's footprint without sacrificing performance.
$199 pricing. SpaceX's 10-Q discussions referenced a 28% gross margin target on terminal hardware. At current component costs that lands the consumer price for a meaningful upgrade closer to $549-$649.
Available before Q4 2026. User terminal certification typically takes 6-9 months post-filing. The earliest plausible launch window is late 2026; more realistically Q1 2027.
Should you wait?
If you need internet today: no, buy what's available now. Gen3 is a mature, stable product, and "waiting for the next generation" is how you spend two years without service.
If you're planning a permanent installation in 2027: probably wait. The form factor changes (if my reading of the FCC filing is right) will be substantial enough that mount kits won't transfer, and you don't want to drill mounting holes for a dish that's about to be obsolete.
