Amazon Leo is planning 40+ satellite launches on United Launch Alliance’s Vulcan rocket.

PlanGrowthRelationshipsValue 4.0Jul 2, 2026RT by @GewoonLukas_: RT by @GewoonLukas_: Last few launches were big for @AmazonLeo - bringing us to 390+ satellites deployed, enough to support continuous service across initial latitudes. Still lots of work ahead – including raising all these new satellites to their assigned altitude – but we’ve completed enough launches for initial service this yr, and future missions just add coverage and capacity. Thanks @ulalaunch Atlas V for getting us to this point. Ready for 40+ sat launches on Vulcan. 🚀 🚀 🚀

It's been impressive to watch ULA launch these Atlas V's in quick succession, especially the last couple months with sub-1 month turnarounds, and makes me excited for what will be possible with Vulcan.
