SpaceX is pitching for the part of the Golden Dome initiative called the "custody layer," a constellation of satellites that would detect missiles, track their trajectory, and determine if they are heading toward the U.S., according to two sources familiar with SpaceX's goals.

Musk's rocket and satellite company is partnering with software maker Palantir PLTR.O and drone builder Anduril on a bid to build key parts of Golden Dome, news agency Reuters reported citing sources.
