Amazon's Kuiper satellites pile up as only Europe's Ariane 6 delivers launches

Amazon's Project Kuiper satellite internet constellation is facing a serious launch bottleneck. Despite manufacturing several satellites per day, hundreds are sitting idle in a Florida payload processing facility. Of the three large new rockets Amazon bet on four years ago—Ariane 6, Blue Origin's New Glenn, and ULA's Vulcan—only Arianespace's Ariane 6 has successfully launched Kuiper satellites, with two missions completed and a third launching Wednesday from French Guiana.

Meanwhile, New Glenn suffered a catastrophic test firing explosion in late May that damaged its launch pad, likely delaying its debut by 12-18 months. The same BE-4 engine powers Vulcan's first stage, complicating its return to flight as well. Amazon has diversified launch contracts—38 on Vulcan and up to 27 on New Glenn—but so far only about 330 of the planned 3,236 satellites are in orbit. Metayer insists Amazon remains on track to begin commercial service later this year, though the launch delays raise questions about timeline credibility.
