United Launch Alliance (ULA) is preparing to resume Vulcan rocket flights following a suspension caused by recurring nozzle issues with GEM-63XL solid rocket boosters. The upcoming Amazon Leo LV-01 mission is scheduled for November 13 from Space Launch Complex 41 in Florida.
The Vulcan VC6L configuration will carry 40 satellites into a 450 km circular orbit. This launch marks the first of up to 38 missions contracted by Amazon to build its broadband constellation. The company aims to deploy 578 satellites for initial regional service, with a total network plan of 3,236 units.
Following nozzle failures on previous flights, Northrop Grumman implemented design and manufacturing fixes for the GEM-63XL boosters. Data gathered during the LV-01 mission will be used to further refine the hardware. The rocket is capable of generating 17.2 mN of thrust and carrying up to 27,200 kg to low-Earth orbit.
Amazon holds an FCC waiver allowing the company to complete its constellation by July 30, 2029. The project has secured commercial customers including Delta Air Lines and JetBlue Airways. ULA has established a dedicated Amazon Vertical Integration Facility to support the increased launch cadence required for the constellation.
