“The payloads for this launch are the second set of 10 Iridium NEXT satellites. Iridium NEXT will replace the world’s largest commercial satellite network of low-Earth orbit satellites in what will be one of the largest “tech upgrades” in history. Iridium has partnered with Thales Alenia Space for the manufacturing, assembly and testing of all 81 Iridium NEXT satellites, 75 of which will be launched by SpaceX. The process of replacing the satellites one-by-one in a constellation of this size and scale has never been completed before.” -SpaceX
