SpaceX · V2 / V3 (Gen2 / Gen3)

SpaceX Starlink

SpaceX's LEO broadband constellation. The supply chain is almost entirely in-house: SpaceX builds the satellite bus, phased-array antennas, optical laser terminals and Hall-effect thrusters at Redmond, WA [2]. The one clearly-named external component supplier is STMicroelectronics, which co-designs RF/mixed-signal silicon used across user terminals and 10,000+ satellites including the latest V3 [3][4]. Generation trajectory: V2 Mini (Falcon 9 workhorse, ~740 kg) → V2 full Gen2 (~1,250 kg, Starship-class, largely superseded) → V3 (~2,000 kg, Starship, 1 Tbps downlink, first operational deliveries 2026) [1][2].

3 個 variant

Starlink V2 Mini

Operational (since 2023)

Current operational workhorse. ~740 kg launch mass, Ku/Ka-band user links, optical inter-satellite laser links, argon Hall-effect thrusters; stacks flat for Falcon 9 [2]. ~80 Gbps-class per-satellite downlink (widely reported). Baseline for the V3 step-up.

Starlink V2 (full Gen2)

Largely superseded by V3

Originally-planned full Gen2 satellite — ~1,250 kg, Ku/Ka/E-band phased arrays, designed to launch on Starship [2]. Largely superseded in practice: SpaceX flew V2 Mini on Falcon 9 as the interim and then jumped to V3, so few/no full-V2 units were deployed.

Starlink V3

First operational deliveries 2026 (Starship)

Next-gen, revealed 2025-10-13. ~2,000 kg, ~1 Tbps downlink and ~200 Gbps uplink per satellite; ~60 V3 sats per Starship launch add ~60 Tbps to the network (>20× a V2 Mini Falcon 9 launch) [1]. Ku/Ka/E-band; first operational deliveries targeted for 2026 [1].
