United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947.
NROL-22 (Trumpet 4)
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.
