Amazon Leo rockets: why built satellites wait on the ground

Published 2026-11-04

As of Nov 3, 2026, rockets, not satellites, set Amazon Leo’s pace. Amazon says it has built more than 1,000 satellites, and its next launches with dates are LV-01 on Vulcan (targeted for Nov 13) and LE-04 on Ariane 6 (no earlier than Nov 23).

The gap is easy to see. On Oct 8, 2026, Amazon said it “has built more than 1,000 satellites for its growing constellation”. Its mission page says it “has launched nearly 400 satellites to date across 14 missions”. By subtraction, roughly 600 finished satellites are on the ground. No Leo satellite has launched since Jul 2, 2026.

Five rocket families, one table

Amazon Leo (formerly Project Kuiper) bought launches from four companies across five rocket types. In April 2022 Amazon signed for up to 83 launches over five years, on top of nine Atlas V launches bought in 2021. By late 2025 it had secured more than 100 launches in all.

The 14 production missions so far split eight on Atlas V, three on Falcon 9 and three on Ariane 6. The two rockets with the most bookings, Vulcan and New Glenn, account for zero.

Atlas V: the workhorse that’s done

Atlas V carried the program’s first hardware: two prototype satellites on Oct 6, 2023. Production launches followed from Apr 28, 2025, when the first 27 satellites went up. Atlas V flew KA-01 through KA-03 in 2025 and LA-04 in December 2025.

In April 2026, an engine upgrade on the rocket’s Centaur upper stage made room for a fourth tier of satellites, so LA-05 carried 29 instead of 27. LA-06 and LA-07 followed in April and May. LA-08 on Jul 2, 2026 was, by Amazon’s count, the ninth and final Atlas V bought for the program. It’s also the last Leo launch to date.

Falcon 9: three flights, ten more bought

In December 2023 Amazon bought three Falcon 9 launches from SpaceX, the company that also runs Starlink. They flew as KF-01 (Jul 16, 2025), KF-02 (Aug 11, 2025) and KF-03 (Oct 13, 2025, US Eastern time), with 24 satellites each.

Amazon said in March 2026 that “late last year, we secured another 10 launches on SpaceX’s Falcon 9 rocket”. None of those 10 had flown by late October 2026, and no dates have been published. Buying rides from its main competitor’s launch company is one more sign that launch capacity, not satellites, has been the constraint.

Ariane 6: three flights, more booked

Arianespace’s first four-booster Ariane 64 carried 32 Leo satellites on Feb 12, 2026 (LE-01). LE-02 added 32 more on Apr 30. LE-03, with upgraded P160C boosters, carried 36 on Jun 17, bringing Arianespace’s total for Amazon to 100 satellites across three flights.

On Sep 9, 2026, Amazon ordered six more Ariane 64 launches, taking its total from 18 to 24. Arianespace said those new flights begin in 2029, so they don’t speed up the next two years.

Next is LE-04: 36 satellites, “planned no earlier than November 23” from French Guiana, which would bring Arianespace’s total for Amazon to 136.

Vulcan: a booster anomaly, then a first Leo flight

Vulcan is the backbone of Amazon’s plan: 38 launches, each initially carrying 40 satellites. It hasn’t flown a Leo mission yet.

On Feb 12, 2026, a solid rocket booster underperformed on Vulcan’s USSF-87 launch for the US Space Force, though the payload still reached its orbit. ULA hasn’t flown Vulcan since. In July, SpacePolicyOnline reported that “Vulcan launches are on hold following an anomaly earlier this year.”

On Oct 28, 2026, Amazon set LV-01, its first Vulcan mission, “with liftoff targeted for Friday, November 13, 2026, pending range approval”, from Space Launch Complex 41 at Cape Canaveral. It carries 40 satellites, Amazon’s largest Leo payload so far. ULA’s own mission page lists the same date. Our news post on LV-01 has the details. Launch dates often slip, so check the tracker on the day.

New Glenn: 24 launches booked, a ground-test explosion

Amazon’s 2022 deal included 12 New Glenn launches plus 15 options. By late 2025 it had converted options to reach “a total of 24 firm launches on New Glenn.” Each initial mission would carry 48 satellites, the most of any rocket in the plan.

On the evening of May 28, 2026, New Glenn exploded during a static-fire test at Cape Canaveral. SpacePolicyOnline reported that the company was testing “in advance of the planned launch of 48 Amazon Leo satellites next week.” The satellites weren’t on the rocket. Neither Amazon nor Blue Origin has announced a new date for New Glenn’s first Leo mission.

How 2026 went, rocket by rocket

Read in date order, the year explains the gap better than any single setback:

• Jan 30: with about 180 satellites up, Amazon asked the FCC for more time on its July milestone, projecting about 700 satellites by July and citing late rockets.
• Feb 12: Ariane 6 flew its first Leo mission. The same day, Vulcan’s booster anomaly on a Space Force launch grounded the rocket that holds 38 of Amazon’s launches.
• Mar 23: Amazon said it planned more than 20 missions in its second year of deployment, including the first New Glenn and Vulcan flights, with over 200 satellites stacked and ready.
• Apr 4 to Jul 2: six missions flew, four on Atlas V and two on Ariane 6.
• May 28: New Glenn was lost in a ground test days before its first planned Leo launch.
• Jul 2: the last Atlas V bought for the program flew. No Leo launch has flown since.
• Jul 30: the FCC’s half-way date passed with Amazon at “nearly 400” satellites against 1,616 required. A June waiver kept the licence alive.
• Sep 9: Amazon added six Ariane 64 launches, starting in 2029.
• Oct 28: Amazon set LV-01 on Vulcan for Nov 13.

The pattern is a narrow pipeline. When Atlas V ran out, only Ariane 6 was flying for Amazon, and its next Leo flight was months away. The news post on the launch pause covers that gap.

What this means for coverage timing

For households, the rocket story answers one question: how fast can the network grow?

• The factory isn’t the limit. Amazon said in March its factory can build up to 30 satellites a week, and it now has hundreds waiting.
• The plan slipped. On Mar 23, 2026 Amazon said it was “on pace to more than double our annual launch rate to over 20 missions” in its second year of deployment. After that, six missions flew between Apr 4 and Jul 2, and none has flown since.
• The next month matters. If LV-01 and LE-04 both fly as planned, they’d add 76 satellites. Broadband Breakfast reported on Oct 9 that, according to a Leo vice president, there would be “at least three” launches in the rest of 2026, starting with Vulcan, then Ariane 6, then more Vulcans.
• The long deadline stands. Amazon must have all 3,232 first-generation satellites in orbit by Jul 30, 2029 under its FCC licence.

None of these launches comes with a promise about US home service. Amazon says initial service starts “in certain locations later this year”, without naming the US. The launch tracker logs every launch as it happens, and the launch-date page follows what Amazon says about service.
