ula

ULA's remaining Atlas V rockets are exclusively reserved for Boeing's Starliner missions, while Amazon's Leo satellite constellation faces delays as it relies on Vulcan, New Glenn, Ariane 6, and Falcon 9 for launches, with only Ariane 6 and Falcon 9 currently operational.

Amazon has hundreds of flight-ready satellites waiting to launch for its Kuiper internet constellation, but only Europe's Arianespace has reliably delivered new rockets as scheduled, while Blue Origin and ULA lag behind.
