It sent 36 Amazon Leo broadband internet satellites into low Earth orbit.<\/p>\n<p>This was the third of 18 Ariane 6 flights booked by Amazon Leo to deploy its constellation and followed successful flights in February and April.<\/p>\n<p>\u201cWe have both institutional and commercial clients and our main and biggest client today is Amazon. And I must say, we are very proud to work together,\u201d said David Cavaillol\u00e8s, CEO of Arianespace, during a pre-launch press briefing. \u201cFor me, it\u2019s much more than a contract. It\u2019s really a partnership.\u201d<\/p>\n<p>Liftoff from Europe\u2019s Spaceport in French Guiana happened at 9:21 a.m. Kourou time (8:21 a.m. EDT \/ 1221 UTC).<\/p>\n<p><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/qRLcka54WRQ?si=H52qcCxrdlWBO9Ws\" width=\"678\" height=\"381\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><span data-mce-type=\"bookmark\" style=\"display: inline-block; width: 0px; overflow: hidden; line-height: 0;\" class=\"mce_SELRES_start\">\ufeff<\/span><\/iframe><\/p>\n<p>While all three of the Amazon Leo missions for Arianespace have used the Ariane 64 configuration of the rocket with four solid rocket boosters, the LE-03 mission will debut the upgraded version, called P160C.<\/p>\n<p>Compared to the predecessor P120C design, the P160C is a meter longer and holds about 156 tons of solid propellant. That\u2019s about 14 more tons than the P120C boosters, allowing for a 10-15 percent increase in performance for the launcher.<\/p>\n<p>The P160C boosters can produce 3,800 kN of thrust each at liftoff compared to 3,700 kN of thrust from the P120C boosters. This iteration of the Ariane 64 can deliver 36 Amazon Leo satellites to orbit, four more than previously.<\/p>\n<p>Cavaillol\u00e8s said described this upcoming launch as a big milestone for the company.<\/p>\n<p>\u201cIt\u2019s important and we want to secure this milestone. This is our focus as of today, but of course, the story doesn\u2019t stop there,\u201d Cavaillol\u00e8s said. \u201cThe more we launch, the better we know the launcher. We are already looking at further improvements. So we\u2019ll do our best to keep increasing the performance of the launcher and thus the number of satellites we can carry for each launch.\u201d<\/p>\n<blockquote class=\"twitter-tweet\" data-twitter-extracted-i1782461142811246287=\"true\">\n<p dir=\"ltr\" lang=\"en\">For the first time, Ariane 64 will fly with four P160C boosters.<\/p>\n<p><img decoding=\"async\" draggable=\"false\" role=\"img\" class=\"emoji\" alt=\"\ud83d\udccf\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f4cf.svg\"> +1 meter longer than P120C<br \/>\n<img decoding=\"async\" draggable=\"false\" role=\"img\" class=\"emoji\" alt=\"\ud83d\udd25\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f525.svg\"> 156 tonnes of propellant pic.twitter.com\/q5gdSWT274<\/p>\n<p>\u2014 Arianespace (@Arianespace) June 4, 2026<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.x.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>Less than 2.5 minutes after liftoff, the four P160C boosters separated from the Ariane 6 main stage, followed by fairing jettison less than a minute later. The first and second stages separated nearly eight minutes into flight and the Vinci engine began the first of two, pre-deployment burns.<\/p>\n<p>The deployment sequence for the Amazon Leo satellites began nearly an hour-and-a-half into flight and conclude at about one hour and 51 minutes post-liftoff. The Vinci engine then performed a de-orbit burn about two hours and 40 minutes after takeoff.<\/p>\n<p>\u201cWhen this mission is complete, Arianespace will have launched 100 of our satellites to date. That\u2019s three missions in less than five months, which is just fantastic,\u201d said Steven Metayer, vice president of Production Operations at Amazon.<\/p>\n<p>\u201cIt\u2019s just something we really count on to build that constellation out at rate across all providers.\u201d<\/p>\n<h4>Building a constellation<\/h4>\n<p>Prior to Wednesday\u2019s launch, Amazon has deployed 331 satellites on 12 missions by three different launch providers: Arianespace, SpaceX, and United Launch Alliance.<\/p>\n<p>Metayer said production of the satellites is ramping up and is exceeding the rate at which they are currently able to get them into orbit. He said Amazon is currently manufacturing \u201cseveral satellites per day\u201d at their facilities in the State of Washington.<\/p>\n<p>In Florida, he said they are able to receive satellites at their payload processing facility at NASA\u2019s Kennedy Space Center and get them integrated into a dispenser in about a week.<\/p>\n<p>\u201cWe\u2019re comfortable right now running ahead of launch. We know that when these heavy lift vehicles, such as the Ariane 64 and then you add the Vulcan and New Glenn to that, we know that we\u2019ll have quite a consumption rate demand from launches,\u201d Metayer said. \u201cSo we\u2019re comfortable right now building ahead of where we need to be and to make sure we never ever run out of satellites.\u201d<\/p>\n<p>Those two launchers, New Glenn and Vulcan, are both grounded for an undetermined amount of time.<\/p>\n<p>For ULA, it\u2019s Vulcan rocket has been grounded due to a problem with one of its solid rocket boosters during the USSF-87 mission in February. The timeline for concluding its anomaly investigation isn\u2019t publicly known, but Metayer said Amazon is anticipating being able to launch its first Leo Vulcan mission \u201csometime in Q3, the end of Q3.\u201d<\/p>\n<p>ULA stacked its first Vulcan rocket that will carry Amazon Leo satellites inside the newly completed Vertical Integration Facility \u2013 Amazon (VIF-A) at Space Launch Complex 41 at Cape Canaveral Space Force Station. The rocket will roll out to the pad for a wet dress rehearsal this summer to validate ULA\u2019s new Centaur upper stage, which the company said is optimized for low Earth orbit missions.<\/p>\n<blockquote class=\"twitter-tweet\" data-twitter-extracted-i1782461142811246287=\"true\">\n<p dir=\"ltr\" lang=\"en\">Behind the scenes as prep continues for Leo Vulcan 1 (LV-01), the first of 38 Vulcan missions on contract with @ULAlaunch.<\/p>\n<p>Teams have completed integration of the first LEO-optimized Centaur upper stage with Vulcan inside Amazon\u2019s dedicated Vertical Integration Facility (VIF-A),\u2026 pic.twitter.com\/2BZgecrbbl<\/p>\n<p>\u2014 Amazon Leo (@Amazonleo) June 2, 2026<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.x.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>On the Blue Origin side of the equation, a month after recovering from an upper-stage, in-flight anomaly on its NG-3 mission, the company lost its sole launch pad in an explosion of its New Glenn rocket during a static fire test on May 28.<\/p>\n<p>During an appearance at the annual VivaTech conference in Paris on Wednesday, Blue Origin CEO Dave Limp reaffirmed the company\u2019s goal of resuming launches from Cape Canaveral Space Force Station by the end of the year.<\/p>\n<p>\u201cWe brought in 400 pieces of heavy equipment, brought in construction workers that were working 24\/7. And so now the pad has been cleared of all debris. It\u2019s amazing how quickly that\u2019s happened,\u201d Limp said to panel moderator and former NASA astronaut Mike Massimino. \u201cJust yesterday, we started the reconstruction. We\u2019re going to fly this year.\u201d<\/p>\n<p>Metayer noted that the 24 launches procured using New Glenn rockets represent \u201cless than 25 percent of our total.\u201d<\/p>\n<p>\u201cWe definitely want to see New Glenn come to service and we definitely look forward to flying on them, but they\u2019re not the only provider,\u201d Metayer said. \u201cWe have a diversified launch portfolio intentionally to do that and we have quite a few launches coming up on others.\u201d<\/p>\n<p>Metayer said Amazon is planning on launching about six more times this year across multiple launch vehicles. The next one after the Ariane 64 mission on Wednesday is expected to be the Leo Atlas 08 mission on July 3, which will be the final non-government launch of an Atlas 5 rocket.<\/p>\n<p>He said they also have one more Ariane 64 launch scheduled this year, but didn\u2019t specify exactly when.

I will say, they\u2019re very reliable on their manifest dates, they\u2019re very reliable and safe on their insertions in orbit,\u201d he said. \u201cSo we definitely would continue to look forward to the next 16 launches with them on our existing contract and we see them being a player long term beyond that.\u201d<\/p>\n<p>Amazon was up against a challenging deadline with the Federal Communications Commission since it was originally required to have deployed and be operating half of its 3,232 satellite constellation by July 30, 2026.<\/p>\n<p>However, earlier this month, the FCC granted a waiver requested by the tech giant, but not without some conditions attached.<\/p>\n<p>\u201cSpecifically, we impose upon Amazon Leo meaningful conditions that incent the company to continue deploying satellites at a rapid clip by temporarily demoting the spectral priority of satellites launched after the relevant July 2026 milestone deadline, until and unless Amazon Leo builds those satellites at a faster pace,\u201d wrote Jay Schwarz, the chief of the FCC\u2019s Space Bureau. \u201cWe act today mindful of the specific record developed on Amazon Leo and in a way that will encourage rapid builds and launches.\u201d<\/p>\n<p>He added that \u201cany authorized satellites in the Gen1 Authorization that are not deployed and operational, will temporarily lose the associated priority status granted in both the 2020 Ka\/Ku-band Processing Round and the 2021 V-band Processing Round and will be reassigned to a later priority status. This loss of status will last for twenty (20) months\u2014until March 30, 2028\u2014or until 50% of the constellation is launched and operational, whichever occurs first.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An Arianespace Ariane 64 rocket lifts off from Europe\u2019s Spaceport in French Guiana to begin the Leo Europe 03 mission for Amazon Leo.
