SpaceX has posted a number of new job openings that suggest it may be developing a classified satellite network. As reported in Teslarati, the new positions require technical skills involving low-cost satellite networks but also require top secret clearances.
One reasonable explanation for these new job openings would be that the US Government is exploring new approaches to satellite networks. DARPA has previously announced funding of up to $117 million for the Blackjack program, seeking to place 20 test satellites in orbit.
SpaceX has announced current plans to raise $750 million in debt financing to support next generation rocket development as well as the Starlink program. It appears SpaceX might have its eyes on additional Starlink funding from government sources.
