Mission Details

Trumpet 4 (USA-184) (NROL-22)

These spacecraft are probably the replacement for the Trumpet SIGINT satellites operating in a Molniya orbit. As no name is known, these are referred here as "Trumpet Follow On". Possibly these satellites might be named Raven.

These satellite most likely use a large, unfurlable dish antenna to collect the signals. Advances in both antenna and electronics technologies have allowed for a large reduction in size compared the Trumpet predecessors.
