<\/p>\nAmazon\u2019s announcement of three launch contracts totaling 83 flights split across Ariane 6, Vulcan, and New Glenn represents the largest commercial launch block buy in history and will unite Arianespace, United Launch Alliance, and Blue Origin in a multi-year effort to deploy the Kuiper internet constellation.<\/p>\n
The contracts represent unique challenges to some providers and opportunities for others to continue filling out the manifest offered by these heavy-lift rockets.<\/p>\n<\/p>\n
The contracted missions are in addition to the nine operational Kuiper launches already announced for the Atlas V rocket. The first two test satellites are also not included in the above figures and are scheduled to launch on ABL Space Systems\u2019 RS1 rocket by Quarter 4 of 2022.<\/p>\n
Exactly when launches of operational Kuiper satellites will begin has not been revealed by Amazon, but the constellation will feature a planned total of 3,236 broadband satellites to bring internet access to underserved communities and regions.<\/p>\n
Per FCC regulatory requirements, Amazon must deploy at least half of the 3,236 Kuiper satellites by July 2026.<\/p>\n
Arianespace<\/p>\n
Of the 83 missions awarded, Arianespace won 18, all of which will fly on the upcoming Ariane 6 in its A64 configuration.<\/p>\n

The A64 variant utilizes the Vulcain 2.1 engine \u2013 a liquid hydrogen and liquid oxygen fed engine \u2013 on the Lower Liquid Propulsion Module (or core stage) in combination with four side-mounted P120C solid rocket motors. <\/p>\n
The rocket also has the Upper Liquid Propulsion Module (or second stage), which features a restartable engine for precise orbital insertion operations.<\/p>\n
Speaking to NASASpaceflight about the award, Wiener Kernisan, President of Arianespace, Inc., said, \u201cThis is the largest contract we\u2019ve ever signed, and this is really a good boost of confidence for the Ariane 6 on the marketplace.\u201d<\/p>\n
For Arianespace, these 18 launches over three years will fit the existing Ariane 6 manifest for institutional commitments to European launch needs.<\/p>\n
\u201cThe manifest will basically be around the institutional launches that we will have to do for ESA and our partners,\u201d said Kernisan. \u201cAnd the manifest was constructed like that. We have a few opportunities during the years for commercial customers.\u201d<\/p>\n
The ability to process more than one Ariane 6 rocket in the new horizontal integration facility before moving to the pad for launch is an already-in-place operation that will help streamline the amount of time between launches.<\/p>\n
