According to NASA's National Space Science Data Center, Trumpet SIGINT satellites have a large deployable mesh antenna, and were initially aimed at monitoring Soviet communications and missile tests. Trumpet 5 is allegedly the second satellite of a new series. Its tasks are believed to be signals intelligence and early warning, using a SBIRS HEO-2 infrared missile early warning package. In addition it is supposed to carry a NASA/Los Alamos TWINS-B magnetospheric research payload.
